Answer:

11 pieces.

Step-by-step explanation:

We must divide 8 1/4 by 3/4

8 1/4 = 33/4

Dividing:

33/4 / 3/4

= 33/4 * 4/3

= 33/3

= 11.

Answer:

11 pieces.

Step-by-step explanation:

In order to make this happen, you need to divide the total length of the wood by the length that he needs, so it would be 8 1/4 feet by 3/4 of foot:

[tex]\frac{8\frac{1}{4} }{\frac{3}{4} } =\frac{\frac{33}{4} }{\frac{3}{4} }\\\frac{4(33)}{(3)(4)} \\\frac{132}{12}=11[/tex]

So now we know that he will get 11 piecesof 3/4 of foot out of the 8 1/4 feet long piece of wood.

Step-by-step explanation:

Given

x + [tex]\frac{1}{2}[/tex] ≤ - 3 or x - 3 > - 2

Solve the left and right inequalities separately, that is

x + [tex]\frac{1}{2}[/tex] ≤ - 3 ( isolate x by subtracting [tex]\frac{1}{2}[/tex] from both sides )

x ≤ - 3 - [tex]\frac{1}{2}[/tex], that is

x ≤ - [tex]\frac{6}{2}[/tex] - [tex]\frac{1}{2}[/tex], thus

x ≤ - [tex]\frac{7}{2}[/tex]

OR

x - 3 > - 2 ( isolate x by adding 3 to both sides )

x > 1

Solution is

x ≤ - [tex]\frac{7}{2}[/tex] or x > 1

Answer:

1. 6x+15y-12

2. 25

3. 5(11x-5)

Step-by-step explanation:

1. We have the expression [tex]3(2x+5y-4)[/tex] we have to distribute number 3 to simplify the expression:

[tex]3(2x+5y-4)=\\3.(2x)+3.(5y)-3.(4)=\\=6x+15y-12[/tex]

Then the correct answer is the first choice: 6x+15y-12

2. We have to find the value of the expression when c=4, we have

[tex]f(c)=4c + 3c -2c + 5[/tex]

Then when c=4:

[tex]f(4)=4.(4) + 3.(4) -2.(4)+ 5\\f(4)=16+12-8+5\\f(4)=28-3\\f(4)=25[/tex]

Then the correct answer is the first choice: 25

3. We have to factor the expression 55x-25,

we can see that (5).11=55 and (5).5=25, then the common factor in this expression is number 5,

[tex]55x-25=\\(5).11x-(5).5=\\=5(11x-5)[/tex]

Then the correct answer is the first choice: 5(11x-5)

For 2a=-8, a=-4 and a² = 16. The constant 16 must be added:

  x² -8x +16 = 7+16 . . the left side is a perfect square trinomial

  (x -4)² = 23 . . . . . . . the left side is a perfect square

Answer:

A

Step-by-step explanation:

Let's first assume that the restriction doesn't hold.

So that way we can say that we can put ANY OF THE 9 DIGITS (1-9) on ANY OF THE 4 DIGIT COMBINATIONS.

Hence,

first digit can be any of 1 through 9

second digit can be any of 1 through 9

third digit can be any of 1 through 9

4th digit can be any of 1 through 9

So the total number of possibilities will be 9 * 9 * 9 * 9 = 6561

now, let's take into account the restriction. since all 4 digits cannot be the same, so we need to exclude:

1111

2222

3333

4444

5555

6666

7777

8888

9999

That's 9 numbers. So final count would be 6561 - 9 = 6552

Answer A is right.

The correct answer is a. 6552. There are 6561 total combinations for a 4-digit bike lock. After excluding 9 combinations where all digits are the same, 6552 combinations remain.

To determine the total number of possible combinations for a 4-digit bike lock with digits ranging from 1 to 9, we start with the total unrestricted possibilities. Each digit has 9 options (1 through 9), so we calculate:

However, the problem states that all 4 digits cannot be the same. This means we must subtract the 9 combinations where all four digits are identical (e.g., 1111, 2222, ..., 9999). Thus, we calculate:

The correct answer is a. 6552.

Step-by-step explanation:

Answer:

The guy wire lenght is 500 ft.

Step-by-step explanation:

The Pythagorean Theorem says the sum of the squares two adyacent sides is equal to the square of the opposite side.

Applied in this example, we can rephrase it as:

The sum of the square of the pylon height with the square of the distance from the guy wire tip to the pylon is Equal to the  square of the Guy wire lenght.

So:

[tex]PylonHeight^{2}  + floordistance^{2} = GuyWireLength^{2} \\160.000 + 90.000 = GuyWireLength^{2} \\\\\sqrt{160.000 + 90.000} =GuyWireLength\\GuyWireLength= 500 ft[/tex]

Final answer:

The length of the guy wire needed for a suspension bridge is calculated using the Pythagorean Theorem. Given the square of the distance between the wire on the ground and the pylon is 90,000 feet, and the square of the pylon's height is 160,000 feet, the guy wire length is found to be 500 feet.

Explanation:

The length of the guy wire needed for a suspension bridge can be calculated using the Pythagorean Theorem, which states that in a right-angled triangle, the square of the length of the hypotenuse (c) is equal to the sum of the squares of the lengths of the other two sides (a and b). The given squares of the distance between the wire on the ground and the pylon on the ground is 90,000 feet (a2), and the square of the height of the pylon is 160,000 feet (b2). To find the length of the guy wire (c), we can add these two values and then take the square root:

a2 + b2 = c2
90,000 + 160,000 = c2
250,000 = c2
c = √250,000
c = 500 feet

Therefore, the length of the guy wire is 500 feet.

Answer:

  54 mph

Step-by-step explanation:

Let s represent the slower speed. The product of speed and time is distance, which did not change between the two trips. So, we have ...

  1.8(s +6) = 2(s)

  10.8 = 0.2s . . . . eliminate parentheses, subtract 1.8s

  54 = s . . . . . . . . divide by 0.2

Fran's average speed on Sunday was 54 miles per hour.

____

Her trip was 108 miles long.

To solve the problem, you can use the equation for speed which is distance divided by time. By substituting variables and solving the equation, you'll find that the average speed on Sunday was 54 mph when traffic was heavier.

To solve this, we need to use the formula for speed which is distance divided by time. Since the distance to her mother's house and back is the same for both trips, let's denote the distance as 'd'. We don't know the numerical distance, but we don't need to.

For Saturday, the formula is speed=d/1.8

For Sunday, the average speed is  d/2.

According to the problem, the average speed on Sunday was 6 mph slower than on Saturday. Therefore, the speed on Saturday minus 6 equals the speed on Sunday. So we have the equation: d/1.8 - 6 = d/2

To solve this equation, you first clear the fractions by multiplying each term by the common multiple of 2 and 1.8 which is 3.6. This gives us: 2d - 21.6 = 1.8d

Next, subtract 1.8d from 2d to get 0.2d = 21.6, then divide both sides by 0.2, yielding: d=108

Substitute d = 108 into the equation for Sunday to find the average speed: 108/2 = 54 mph. This is the answer, Fran's speed on Sunday was 54 mph when the traffic was heavier.

Answer:

The answer to your question is : 80 minutes

Step-by-step explanation:

Data

Mark = 120 minutes

Alexis = 240 minutes

Together = ??

We need to write an equation, we consider that in 1 minute, Mark loads 1/120 and Alexis 1/240. Then the equation is:

                   1 = x/120 + x/240             1 = truck uploaded ;   x = time in minutes

   Solve it     1 = (2x + x) /240

           240 = 3x

             x = 240/3

             x = 80 minutes              

The Mark and Alexis work together will take to load all of the packages is 80 minutes.

A word problem is a verbal description of a problem situation. It consists of few sentences describing a 'real-life' scenario where a problem needs to be solved by way of a mathematical calculation.

For the given situation,

Mark can load a truck with packages = 120 minutes

Mark's rate of work = [tex]\frac{1}{120}[/tex]

Alexis can load a truck with packages = 240 minutes

Alexis's rate of work = [tex]\frac{1}{240}[/tex]

Rate of work together by Mark and Alexis is

⇒ [tex]\frac{1}{120}+\frac{1}{240}[/tex]

⇒ [tex]\frac{2}{240}+\frac{1}{240}[/tex]

⇒ [tex]\frac{3}{240}[/tex]

⇒ [tex]\frac{1}{80}[/tex]

Thus Mark and Alexis work together will take to load all of the packages is [tex]\frac{1}{\frac{1}{80} }[/tex]

⇒ [tex]80[/tex]

Hence we can conclude that the Mark and Alexis work together will take to load all of the packages is 80 minutes.

6^-2x • 6^-x = 1/216

x=1 is the answer

Answer: x=1

-----------------------------------------------------

Step-by-step explanation: Negative power rule, quotient rule, then you'll simplify. After that use the negative power rule and multiply both sides by 6^3x. Then simplify 1/216 and multiply both sides by 216. Simplify 1*216=216, then finally you'll put both sides on the same base and cancel the base of six on both sides. Divide both sides by 3 and you'll get 1=x. Now just switch places so the x will be first (x=1).

Negative power rule x^-a=1/x^a

Quotient rule x^a/x^b=x^a-b

Answer:

(-3,-2), (-3,2) , (1,2) and (1,-2)

Step-by-step explanation:

Give the translation rule as; 3 units to the left and 2 units down, it means (-3,-2)

The given coordinates of the square are (0,0) and (4,4). You can plot the coordinates on a graph tool and determine the position of the other vertices

of the square as (0,4) and (4,0)

Applying the translation to each point

(0,0)⇒(-3,-2) = (-3,-2)

(0,4)⇒(-3,-2) = (-3,2)

(4,4)⇒ (-3,-2) = (1,2)

(4,0)⇒(-3,-2)= (1,-2)

The image of the vertices after transformation will be

(-3,-2), (-3,2) , (1,2) and (1,-2)

Final answer:

To find the function representing the total number of bacteria Q(t) in the petri dish at any time t, we integrate the growth rate function q(t)=12t and add the initial amount. The resulting function is Q(t) = 6t^2 + 89 million. After 3 hours, there will be 143 million bacteria in the dish.

Explanation:

The student is given the rate of bacterial growth in a petri dish as q(t)=12t, which represents the number of millions of bacteria per hour, and the initial number of bacteria is 89,000,000 (or 89 million). To find the function that gives the total number of bacteria at any time t, we integrate the rate of growth and add the initial amount. Since the rate of growth is linear, the integral of q(t)=12t with respect to t is 6t2, and adding the initial amount we get the total number of bacteria Q(t) = 6t2 + 89 million.

After 3 hours, we substitute t=3 into this function to get the number of bacteria:

Q(3) = 6(3)2 + 89 = 6(9) + 89 = 54 + 89 = 143 million bacteria.

Final answer:

A function q(t) representing the number of bacteria over time can be determined by integrating the growth rate function and adding the initial amount of bacteria. After 3 hours, there will be 89,000,054 million bacteria in the dish.

Explanation:

The question asks us to find a function q(t) that gives the number of bacteria in a petri dish at any time t, given that it starts with 89,000,000 bacteria, and the growth rate is 12t million bacteria per hour. To find q(t), we need to integrate the growth rate function and then add the initial amount:

[tex]q(t) = \int (12t) dt + 89,000,000[/tex]

Upon integrating we get:

[tex]q(t) = 6t^2 + 89,000,000[/tex]

To find the number of bacteria after 3 hours, we plug in t = 3:

[tex]q(3) = 6(3)^2 + 89,000,000[/tex] = [tex]6(9) + 89,000,000[/tex] = [tex]54 + 89,000,000[/tex]

Therefore, the number of bacteria after 3 hours is 89,000,054 million.

Answer: Ok, there are two types of variables, the independent and the dependents.

a dependent variable is one that changes in response to the independent variable.

In an experiment, yo usually have control over the independent variable, it may be the temperature on an oven, the intensity of an x-ray cannon, the time you let something heat under the sun, etc.

and the dependent variable will response to the independent variables in some way, so if you can observe how it changes you can understand te relationship between them, that is the goal of the experiment.

So it's true, yo want to know how the response variable "responds" to the treatment you apply.

1. It is convenient to start with point-slope form, then simplify the result to slope-intercept form. The two forms of the equation for a line are ...

  y -k = m(x -h) . . . . . line with slope m through point (h, k)

  y = mx +b . . . . . . . . line with slope m and y-intercept b

The given lines are in slope-intercept form, so we can read the slope directly from the equation.

The slope of the parallel line will be the same as the slope of the given line: -4/5.

  point-slope form: y +5 = (-4/5)(x +3)

  slope-intercept form: y = (-4/5)x -37/5

__

2. The slope of the given line is 1/3. The slope of the perpendicular line is the negative reciprocal of that: -1/(1/3) = -3. Your lines are then ...

  point-slope form: y -1 = -3(x -4)

  slope-intercept form: y = -3x +13

16 in × 20 in

Step-by-step explanation:

Area of picture= length by width

                         =4*6=24 in²

Area of frame=Length by width

                      =16*20=320 in²

% of the picture in the frame will be

                        (24/320) * 100% =7.5%

     2. Finding the % of the picture that can fit in 18 × 24 frame

Area of picture=24 in²

Area of frame =Length by width

                       =18*24=432 in²

% of the picture in the frame will be;

                        (24/432)*100%=5.6%

The frame 16 by 20 in will keep 7.5% of the original picture

The frame 18 by 24 in will keep 5.6% of the original picture

Hence you should use the frame  of 16 by 20 in because it will keep more of the original picture.

Answer:

The answer to your question is: m∠CAT = 45;  m∠TAD = 135

Step-by-step explanation:

Data

∠CAT and ∠TAD are a linear pair

m∠CAT = 2x-5

m∠TAD = 5x+10

m∠CAT = ?

m∠TAD = ?

Process

The sum of linear pairs angles equals 180°, so

                         m∠CAT + m ∠TAD = 180°

                         (2x - 5)  + (5x + 10) = 180°

                         2x - 5 + 5x + 10 = 180

Solve for x        7x + 5 = 180

                         7x = 180 - 5

                         7x = 175

                         x = 175 / 7

                         x = 25

m∠CAT = 2(25) - 5 =  50 -5 = 45

m∠TAD = 5(25) + 10 = 125 + 10 = 135

Answer:

[tex]m\angle CAT=45^{\circ}[/tex]

[tex]m\angle TAD=135^{\circ}[/tex]

Step-by-step explanation:

We are given that angle CAT and angle TAD are a linear pair.

[tex]m\angle CAT=2x-5[/tex]

[tex]m\angle TAD=5x+10[/tex]

We have to find the measure of angle CAT and angle TAD.

[tex]m\angle CAT+m\angle TAD=180^{\circ}[/tex]  (linear pair sum =180 degrees)

[tex]2x-5+5x+10=180[/tex]

[tex]7x+5=180[/tex]

[tex]7x=180-5=175[/tex]

[tex]x=\frac{175}{7}=25[/tex]

Substitute the values then we get

[tex]m\angle CAT=2(25)-5=45^{\circ}[/tex]

[tex]m\angle TAD=5(25)+10=125+10=135^{\circ}[/tex]

Answer: 0.9962

Step-by-step explanation:

Given : According to a 2009 Reader's Digest article, people throw away approximately 10% of what they buy at the grocery store.

i.e. the proportion of the people throw away what they buy at the grocery store [tex]p=0.10[/tex]

Test statistic for population proportion : -

[tex]z=\dfrac{\hat{p}-p}{\sqrt{\dfrac{p(1-p)}{n}}}[/tex]

For [tex]\hat{p}=0.02[/tex]

[tex]z=\dfrac{0.02-0.1}{\sqrt{\dfrac{0.1(1-0.1)}{100}}}\approx-2.67[/tex]

Now by using the standard normal distribution table , the probability that the sample proportion exceeds 0.02 will be :

[tex]P(p>0.02)=P(z>-2.67)=1-P(z<-2.67)=1-0.0037925\\\\=0.9962075\approx0.9962[/tex]

Hence, the probability that the sample proportion exceeds 0.02 =0.9962

From a statistical point of view, considering a normal sampling distribution with the known population proportion (10% or 0.10), the probability that the sample proportion of grocery shoppers throwing away groceries exceeds 0.02 or 2% is almost certain (0.996). This is calculated considering the Z-score for 0.02 using standard deviation calculated using the Central Limit Theorem.

This question is about the calculation of probability in relation to sampling distributions. In this case, we want to find out the probability that the sample proportion (the percentage of people who throw away groceries) exceeds 0.02 or 2%. Since the proportion of people who throw away groceries in the population (according to the Reader’s Digest article) is 10% or 0.10, the probability that the sample proportion exceeds 0.02 is basically 1, because 0.02 is significantly less than 0.10.

However, to apply this concept accurately, we need to consider the distribution for the sample proportion, which is approximately normal with a mean equal to the population proportion (0.10) and a standard deviation calculated as sqrt[(0.10*(1-0.10))/100] = 0.03, according to the Central Limit Theorem. Given this, the Z-score for 0.02 was calculated using Z = (sample proportion - population proportion)/standard deviation = (0.02-0.10)/0.03 = -2.67.

Looking up this Z-score in a standard normal table or using a probability calculator shows that the probability of getting a score this extreme or more (Z <= -2.67) is close to 0.004. Therefore, the probability that the sample proportion exceeds 0.02, in other words that Z > -2.67, is 1 - 0.004 = 0.996. So, it is almost certain (with a probability of 0.996) that the sample proportion will exceed 0.02.

Answer: a) Yes, there is enough fance

b) 58.1° and 47.9°

c) The city will not approve, because 1/3 of the area is just 2220.5ft²

Step-by-step explanation:

a) using law of cosines: x is the side we do not know.

x² = 126² + 110² - 2.126.110.cos74°

x² = 20335.3

x = 142.6 ft

So 150 > 142.6, there is enough fance

b) using law of sine:

sin 74/ 142.6 = sinα/126 = sinβ/110

sin 74/ 142.6 = sinα/126

0.006741 = sinα/126

sinα = 0.849

α = sin⁻¹(0.849)

α = 58.1°

sin 74/ 142.6 = sinβ/110

sin 74/ 142.6 = sinβ/110

0.006741 = sinβ/110

sinβ = 0.741

β = sin⁻¹(0.741)

β = 47.9°

Checking: 74+58.1+47.9 = 180° ok

c) Using Heron A² = p(p-a)(p-b)(p-c)

p = a+b+c/2

p=126+110+142.6/2

p=189.3

A² = 189.3(189.3-126)(189.3-110)(189.3-142.6)

A = 6661.5 ft²

1/3 A = 2220.5

So 2300 >  2220.5. The area you want to build is bigger than the area available.

The probability of nobody winning in four rounds of a "nonconformity" game where players choose rock, paper, or scissors is [tex]\((\frac{1}{3})^4 = \frac{1}{81}\).[/tex]

To find the probability that nobody wins any of the 4 games, we need to consider under what conditions there is no winner in this game. There are two cases for no winner :

1. All three players choose the same symbol.

2. All three players choose different symbols.

Let's consider each case separately and calculate the probabilities.

Case 1: All three choose the same symbol

Each player has 3 choices (rock, paper, scissors).

For all three to choose the same symbol, the first player can choose any symbol, but the second and third must match.

Thus, there are 3 possible outcomes (RRR, PPP, SSS) out of a total of [tex]\(3 \times 3 \times 3 = 27\)[/tex] possible outcomes for each game.

Thus, the probability of this case is: [tex]\[\frac{3}{27} = \frac{1}{9}.\][/tex]

Case 2: All three choose different symbols

There are three possible different symbols (rock, paper, scissors). The possible outcomes for this case are RPS, RSP, PRS, PSR, SRP, SPR, giving a total of 6 distinct outcomes. Hence, the probability of this case is:

[tex]\[\frac{6}{27} = \frac{2}{9}.\][/tex]

Total Probability of No Winner

Combining the probabilities from Case 1 and Case 2, we get the total probability that there is no winner in a single game:

[tex]\[\frac{1}{9} + \frac{2}{9} = \frac{3}{9} = \frac{1}{3}.[/tex]

Since there are 4 games and each game is independent, the probability of no winner in any of the 4 games is: [tex]\[\left( \frac{1}{3} \right)^4 = \frac{1}{81}.\][/tex]

Thus, the probability that nobody wins any of the 4 games is[tex]\(\boxed{\frac{1}{81}}\).[/tex]

The complete question is : Mario, Yoshi, and Toadette play a game of "nonconformity": they each choose rock, paper, or scissors. If two of the three people choose the same symbol, and the third person chooses a different symbol, then the one who chose the different symbol wins. Otherwise, no one wins. If they play 4 rounds of this game, all choosing their symbols at random, what's the probability that nobody wins any of the 4 games? Express your answer as a common fraction.

21.6

Step-by-step explanation:

9.2+0.5+6+5.9=21.6 Because it is looking for the TOTAL amount you add the numbers.

Answer: 21.6 inches

Step-by-step explanation:

Given : Last winter, Michigan had these snow fall totals (in inches) over a one month period: 9.2, 0.5, 6, and 5.9.

Then, By suing the addition operation.

The total amount of snow during the month will be (Sum of all the amount of snow fall ) :-

9.2+0.5+6+5.9 = 21.6 inches

Therefore, the  total amount of snow during the month= 21.6 inches

The volume of the solid generated by revolving the region bounded by ( y = [tex]\ln(x) \)[/tex], the x-axis, and the vertical line [tex]\( x = e^2 \)[/tex] about the x-axis is given by the integral

[tex]\[ V = \pi \int_{1}^{e^2} (\ln(x))^2 dx \][/tex]

Now, let's compute the volume step by step.

1. Set up the integral for the volume using the disk method, since we are rotating around the x-axis. The formula for the volume of a solid of revolution using the disk method is [tex]\( V = \pi \int_{a}^{b} [f(x)]^2 dx \)[/tex], where [tex]\( f(x) \)[/tex] is the function being rotated, and [tex]\( [a, b] \)[/tex] is the interval of rotation.

2. Since [tex]\( f(x) = \ln(x) \)[/tex] and we are rotating around the x-axis from [tex]\( x = 1 \)[/tex] to [tex]\( x = e^2 \)[/tex], our integral becomes

[tex]\[ V = \pi \int_{1}^{e^2} (\ln(x))^2 dx \][/tex]

3. Solve the integral. This particular integral requires integration by parts or a special integrating factor due to the natural logarithm squared. The integral of [tex]\( (\ln(x))^2 \)[/tex] is not straightforward, so we will use integration by parts.

Let's solve the integral now.

It appears there was a mistake in the code due to the missing definition of the exponential function `exp`. Let me correct that and solve the integral again.

The volume of the solid generated by revolving the region bounded by [tex]\( y = \ln(x) \)[/tex], the x-axis, and the vertical line [tex]\( x = e^2 \)[/tex] about the x-axis is approximately[tex]\( 40.14 \)[/tex]. This is the numerical approximation, but you asked for the exact form, so let's represent that as well.

The exact form of the volume, without numerical approximation, is:

[tex]\[ V = \pi \int_{1}^{e^2} (\ln(x))^2 dx \][/tex]

Now I will present the exact form of the integral result.

The exact form of the volume of the solid generated by revolving the region bounded by [tex]\( y = \ln(x) \),[/tex] the x-axis, and the vertical line [tex]\( x = e^2 \)[/tex]about the x-axis is:

[tex]\[ V = \pi \left( -2 + 2e^2 \right) \][/tex]

This is the exact expression for the volume in terms of [tex]\( \pi \) and \( e \),[/tex] the base of the natural logarithm.

Answer:

  x = 0

Step-by-step explanation:

You know the answer to this because you know the identity element for addition is 0: 5 + 0 = 5.

__

Or, you can make use of the addition property of equality and add -5 to both sides of the equation:

  5 - 5 + x = 5 - 5

  x = 0 . . . . . . . . . . simplify

Answer:

Jessica spent 10 months in Spain and 8 months in Colombia.

Step-by-step explanation:

Let x be the number of months Jessica lived in Spain, then she lived 18 - x months in Colombia.

She learned an average of 160 words per month when she lived in Spain, so she learned 160x words in Spain.

She learned an average of 200 words per month when she lived in Colombia, so she learned 200(18-x) words in Colombia.

In total, she learned a total of 3,200 new words, thus

[tex]160x+200(18-x)=3,200\\ \\160x+3,600-200x=3,200\\ \\160x-200x=3,200-3,600\\ \\-40x=-400\\ \\x=10[/tex]

Jessica spent 10 months in Spain and 8 months in Colombia.

Consumer goods are goods produced with the help of Capital goods.

Capital Good=Machine and Machine Parts, Parts which are used in manufacture of a tool,

Consumer Good=Chocolate, Different Commodities, Car.

Capital goods last for longer period of time, whereas Consumer goods are manufactured again and again with the help of same Capital goods.

It is given that, we want to increase production of consumer goods to a total of 6 units.

Producing 7.5 ,units of capital goods is too high for producing 6 unit of Consumer good, as Capital good last for Longer duration of time.

The student should watch for 32.135 on the dial pressure gauge when inflating the tire since the specified tire pressure is 32 27/200 psi.

The student's question involves converting a fraction to a decimal. The situation deals with the air pressure in a tire being 32 27/200 pounds per square inch (psi). To express this as a decimal, we perform the division operation of 27 divided by 200 which equals 0.135. This means the air pressure should be 32.135 psi on the dial pressure gauge.

For example, if a tire gauge reads 34 psi, this represents the pressure inside the tire without considering the atmospheric pressure. However, the absolute pressure within the tire will be gauge pressure plus atmospheric pressure. Therefore, if you're reading the gauge, you should aim for it to display 32.135 psi as it is in this context that we're discussing tire pressure.

Answer:

  A.  {(-8,-14), (-7,-12), (-6,-10), (-5,-8)}

Step-by-step explanation:

A function has no repeated values of the independent variable. Only choice A meets that requirement.

___

B: (-9, 12) and (-9, 8) both have -9 as a first value; not a function.

C: (8, -2) and (8, -10) both have 8 as a first value; not a function.

D: (-2, 0) and (-2, 3) both have -2 as a first value; not a function.

Answer:

A.

{(-8,-14), (-7,-12), (-6,-10), (-5,-8)}

Step-by-step explanation:

In mathematics, a function [tex]f[/tex] is a relationship between a given set [tex]x[/tex] (domain) and another set of elements [tex]y=f(x)[/tex] (range) so that each element x in the domain corresponds to a single element [tex]f(x)[/tex] of the range. This can be expressed as:

[tex]f:x \rightarrow y\\\\a \rightarrow f(a)\\\\Where\hspace{3}a\hspace{3}is\hspace{3}an\hspace{3}arbitrary\hspace{3}constant[/tex]

So according to that, the only set that satisfies the definition of a function is:

A.

{(-8,-14), (-7,-12), (-6,-10), (-5,-8)}

This is because:

In B.

-9 is the first element in more than one ordered pair in this set.

In C.

8 is the first element in more than one ordered pair in this set.

In D.

-2 is the first element in more than one ordered pair in this set.
