A seven-digit number has a 0 in the ones place,a 6 in the ten thousands place, an 8 in the millions place, and fives in each of the remaining places and what is the number

Answer:

c = 63

w = 85

Step-by-step explanation:

Since the 2 lines are parallels c is the same angle as 63 and w is the supplementary angle of 95

Yes, the average speed for the entire trip from A to C is equal to 80 km/h.

Given

You travel from point A to point B in a car moving at a constant speed of 70 km/h.

You travel the same distance from point B to another point C, moving at a constant speed of 90 km/h.

The average speed is defined as the change in displacement and change in a time interval.

The formula is used to calculate average speed;

[tex]\rm Average \ speed= \dfrac{V_1+V_2}{2}[/tex]

Where [tex]\rm V_1[/tex] is 70 and [tex]\rm V_2[/tex] is 90.

Substitute all the values in the formula

[tex]\rm Average \ speed= \dfrac{V_1+V_2}{2}\\\\\rm Average \ speed= \dfrac{70+90}{2}\\\\\rm Average \ speed= \dfrac{160}{2}\\\\\rm Average \ speed= 80[/tex]

Hence, the average speed for the entire trip from A to C is equal to 80 km/h.

Answer:

A

Step-by-step explanation:

Option: A is the correct answer.

A.    There is a charge of $0.15 for each minute of use.

We know that the slope of the line of best fit represents the ratio of change in the dependent variable to the change in the independent variable.

Here the dependent variable is: Phone bill

and the independent variable is the number of minutes used.

Let the line of best fit passes through (100,60) and (300,90).

This means that the slope of the line of best fit is:

[tex]Slope=\dfrac{90-60}{300-100}\\\\Slope=\dfrac{30}{200}\\\\Slope=0.15[/tex]

Hence, the answer is: Option: A

Final answer:

Juanita will arrive at her aunt's home around 3:00 pm after accounting for 5 hours and 20 minutes of driving time and a 40-minute break to her journey that began at 9:00 am.

Explanation:

The question is asking us to estimate the arrival time for Juanita who is traveling to her aunt's home 320 miles away. Juanita leaves at 9:00 am, drives at an average speed of 60 miles per hour, and plans to take a 40-minute break halfway through her trip.

To estimate the time it will take Juanita to reach her aunt's house, we need to calculate the driving time and add the time for the break.

The driving time is calculated by dividing the total distance by the average speed. The total driving time is 320 miles \'d'vided by' 60 miles per hour, which equals approximately 5.33 hours or 5 hours and 20 minutes of driving time.

Next, we add the 40-minute break to the driving time. Convert 40 minutes to hours by dividing by 60, which is approximately 0.67 hours or 40 minutes. Now, we sum the hours: 5 hours and 20 minutes driving + 40 minutes break = 6 hours total time spent.

Juanita left at 9:00 am, so we add the 6 hours to this time. Therefore, Juanita should arrive at her aunt's home around 3:00 pm.

Answer: a) 70%

b) 6%

c) 24%

d) and: 6%

   or: 66%

e) 46.2%

Step-by-step explanation:

Living on campus = 30%

Living off Campus = 70%

Living on campus with car = 20% of 30% = 0.2 x 0.3 = 0.06 = 6%

Living on campus w/o car = 80% of 30% = 0.8 x 0.3 = 0.24 = 24%

Living off campus with car = 60% of 70% = 0.6 x 0.7 = 0.42 = 42%

Living off campus w/o car = 40% of 70% = 0.4 x 0.7 = 0.28 = 28%

a) 70%

b) 6%

c) 24%

d) Student lives on campus and has an automobile: 6%

   Student lives on campus or has an automobile = 66%

living on campus 30%

students with car = 6% (on campus)  42% (off campus)

30 - 6 + 42 = 66

e) P (living on campus/not have a car) = P(living on campus w/o a car)/P(not have a car)

P(living on campus w/o a car) = 24

Answer: 175760000

Step-by-step explanation:

We know that the total number of digits in the number system is 10  [0,1,2,3,4,5,6,7,8,9]

The total number of letters in English Alphabet = 26

Now, if standard automobile license plates in a country display 2 numbers, followed by 3 letters, followed by 2 numbers, then the number of different standard plates are possible in this system (if repetition of letters and numbers is allowed)will be :_

[tex]= 10\times10\times26\times26\times26\times10\times10\\\\=175760000[/tex]

Hence, the number of different standard plates are possible in this system = [tex]175760000[/tex]

In the given license plate system, there are 175,760,000 possible combinations by calculating the combinations for each segment (2 numbers, 3 letters, 2 numbers) and multiplying them together.

A standard automobile license plate in this system consists of 2 numbers, followed by 3 letters, followed by 2 numbers. To determine the number of different plates possible, we calculate the combinations for each part separately and then multiply them together.

To find the total number of different standard license plates possible, we multiply the combinations for each part:

Total Plates = 100 x 17,576 x 100 = 175,760,000

Therefore, there are 175,760,000 different possible license plates in this system.

Answer:

180h + 15h²

Step-by-step explanation:

Since both have same function i.e. function of f, so we simply put 6 + h and 6 in place of x in f(x)

Here,

f(x) = 15x² + 6

Then, f(6+h) - f(6)

= [15(6 + h )² + 6] - [15(6 )² + 6]

⇒ [15 (36 + 12h + h²) + 6] - [15 × 36 + 6]

⇒ [ 15 × 36 + 15 × 12h + 15h² + 6 - 15 × 36 - 6 ]

⇒ 15 × 12h + 15h²

⇒ 180h + 15h²

Answer:

The answer to your question is:   F = (-6, -4)

Step-by-step explanation:

Segment = EF

mpM = (-2, 2)

first point = E = (2, 8)

second point = F = (x, y)

Formula

      Xmp = (x1 + x2) / 2                         Ymp = (y1 + y2) / 2

      x2 = 2xmp - x1                                y2 = 2ymp - y1

Process

     x2 = 2(-2) - 2                                   y2 = 2(2) - 8

     x2 = -4 - 2                                       y2 = 4 - 8

     x2 = -6                                            y2 = -4

                     F = (-6, -4)

The coordinates of the other endpoint of the line segment EF, given that the midpoint M is (-2,2) and the endpoint E is (2,8), are (-6,-4). This is determined by using the midpoint formula and solving for the remaining variables.

To find the coordinates of the other endpoint F, we apply the midpoint formula which is M ( (x₁ + x₂) / 2, (y₁ + y₂) / 2 ). Here, we have the midpoint M(-2,2) and one endpoint E(2,8).

It's like saying: (-2,2) = ( (2 + x₂) / 2, (8 + y₂) / 2 ).

To solve for x₂ (the x-coordinate of point F) and y₂ (the y-coordinate of point F), we will set up two separate equations based on the x and y coordinates.

For the x-coordinate, (-2) = (2 + x₂) / 2. Solve for x₂ gives x₂ = -2*2 - 2 = -6.

For the y-coordinate, 2 = (8 + y₂) / 2. Solve for y₂ gives y₂ = 2*2 - 8 = -4.

So, point F, the other endpoint of the line segment EF, has the coordinates (-6,-4).

For solving these types of question we use Least Common Multiples (L.C.M.).

Since for getting a common time they will meet, we interested in a multiplier.

Now, We will take L.C.M. of all the numbers:

10 = 2 × 5

8 = 2 × 2 × 2

12 = 2 × 2 × 3

Answer:

[tex]\frac{9x}{40}[/tex] is the answer.

Step-by-step explanation:

The question has some typo errors.

Rashid and Mikhail submitted a total of x pastries to a baking competition.

Suppose say :

Mikhail made x pastries .

Hence Rashid made [tex]\frac{2x}{3}[/tex] pastries.

And in total they made [tex]\frac{5x}{3}[/tex] pastries.

Now we have that out of x, [tex]\frac{5}{8}[/tex] of x were brushed with olive oil.

So, [tex]\frac{3}{8}[/tex] of x that is [tex]\frac{3x}{8}[/tex] are brushed by butter.

So, it becomes [tex](\frac{3}{8}) / ( \frac{5x}{3} )[/tex]

= [tex]\frac{3}{8} \times\frac{3x}{5}[/tex] = [tex]\frac{9x}{40}[/tex]

Hence, answer is option B.

The expression (4 + 5i)(4 - 5i) simplifies to 41, as the multiplication of complex conjugates yields a real number.

The expression (4 + 5i)(4 - 5i) is a product of two complex conjugates. When multiplied, the product of complex conjugates results in a real number because the imaginary parts cancel out. The multiplication proceeds as follows:

Multiplying the real parts: 4 * 4 = 16.

Multiplying the outer terms: 4 * (-5i) = -20i (but this will cancel out with the next step).

Multiplying the inner terms: 5i*4 = 20i (which cancels out the -20i from the outer multiplication).

Multiplying the imaginary parts: 5i * -5i = -25[tex]i^2[/tex]. Remembering that i^2 = -1, we simplify this to -25 * -1 = 25.

Adding the results from steps 1 and 4, we get 16 + 25 = 41.

Therefore, the simplified expression is 41.

Answer:

Tax due on the property : $ 960

Step-by-step explanation:

We know that the property is assessed at the 40% of it's current value.

First we are going to find the value assessed.

40% of $40,000 = 0.4 * 40,000 = $ 16,000

Now, at the value, we are aplying a factor of 1.5. This equalization factor is the multiplier we use to calculate the value of a property that is in line with statewide tax assessments

So, we do, 1.5* $16,000 = $24,000

Now we got that we the tax rate is $4 per $100 assessed.

So we got $24,000 * $4  / $100 = $ 960

Answer:

y = - 2x

Step-by-step explanation:

Given that x and y vary directly then the equation relating them is

y = kx ← k is the constant of variation

To find k use the condition x = - 5, y = 10, thus

k = [tex]\frac{y}{x}[/tex] = [tex]\frac{10}{-5}[/tex] = - 2, hence

y = - 2x ← is the equation relating them

Answer:

The initial population P0 is 7500

Step-by-step explanation:

First of all, we are told that the population is proportional to time. This means that as time goes by, the population will increase. This type of relationship between two variables has the form of a linear equation expressed as:

y = mx + b,

where m is the slope of the curve and b is the intercept of it.

In this case we can state the following equation:

P = mt + P0

Where P is the population at a certain time "t", "m" is the slope of the curve, "t" is the time (this is the independent variable) and P0 is the intercept of the curve and represents the initial population.

Once we state the equation, let's see what we know:

If t = 0, then P = P0

If t = 3, then P = 12000 just as we are told

and if t = 5, then P = 2 P0 because after five years the population has doubled compared to the initial population (P0).

From the definition of the slope of the curve:

(Y2 - Y1)/(X2-X1) = m

and using the data described before we can formulate the slope value:

m = (2P0 - P0)/(5-0)

m = (2P0 - P0)/5

m = P0/5

Then, let's replace the value of m in the following equation:

P = mt + P0

12000 = (P0/5) × 3 + P0 → This is the equation presented when 3 years has gone by and we now have a population of 12000.

12000 = (3/5) P0 + P0

12000 = (8/5) P0

12000×5/8 = P0 = 7500

Then we can calculate the value of the slope m:

m = P0/5

m = 7500/5 = 1500

Now, knowing the value of m and the initial population P0 we are able to calculate the population at any value of "t".

Answer:

(a) The temperature at a specific location as a function of time.

This is a continuous function as the temperature cannot increase in an instant like time.

(b) The temperature at a specific time as a function of the distance due west from New York City.

Final answer:

a) Continuous

b) Continuous

c) Continuous

d) Discontinuous

e) Continuous

Explanation:

In examining whether a function is continuous or discontinuous, we consider if there are any interruptions in the value of the function as the input changes. Here's an analysis for each given scenario:

A continuous probability function has been defined such that probability equals area under the curve of the function over an interval. For real-world phenomena like temperature and altitude, these functions tend to be continuous as they reflect gradual changes over time or distance.

Final answer:

To find the common denominator of 5/6 and 2/7, multiply each fraction by a factor that will give the least common denominator of 42, then subtract the resulting fractions with the same denominator.

Explanation:

To find the common denominator for the fractions 5/6 and 2/7, we need to determine a shared denominator that both original denominators can be multiplied into without changing the value of the fractions. Multiplication is the key technique to creating a common denominator. In this case, the least common denominator (LCD) is 42 because 6 and 7 have no common factors other than 1, and 6 times 7 equals 42. To transform these fractions, we multiply the numerator and denominator of each fraction by the number that will give us our LCD as the new denominator.

To calculate the difference using the LCD:

Multiply 5/6 by 7/7 to get 35/42.

Multiply 2/7 by 6/6 to get 12/42.

Now, subtract the two new fractions: 35/42 - 12/42 = 23/42.

It is essential to remember that we never add or subtract the denominators when combining fractions; we only combine the numerators after establishing a common denominator.

Hello!

if he bought it with no interest applied, then the last payment will be $1400

1670 - 100 = 1570

if he has to pay it off in 18 months (1 and a half years), and only pays $10 per month, that means he will pay off $170 before the last payment is due.

1570 - 170 = 1400

so his last payment will have to be $1400 to pay it off completely

I hope this helps, and have a nice day!

$1,400 is the amount of his last payment.

1. First, determine the total amount Adam needs to pay after the down payment. Adam made a $100 down payment on the $1,670 system, so the remaining amount to be paid is:

[tex]\[ \text{Remaining amount} = \$1,670 - \$100 = \$1,570 \][/tex]

2. Next, calculate the total number of monthly payments Adam will make. Since he agreed to pay off the purchase in 1 and a half years, and there are 12 months in a year, the total number of payments is:

[tex]\[ \text{Total payments} = 1.5 \times 12 = 18 \text{ payments} \][/tex]

3. The minimum monthly payment is $10. To find out how much Adam will have paid after 17 payments (one less than the total number of payments), we multiply the monthly payment by the number of payments:

[tex]\[ \text{Amount paid after 17 payments} = 17 \times \$10 = \$170 \][/tex]

4. Now, subtract the amount paid after 17 payments from the remaining amount to find the last payment:

[tex]\[ \text{Last payment} = \$1,570 - \$170 = \$1,400 \][/tex]

Therefore, the amount of Adam's last payment will be $1,400.

Answer:

[tex]PT =-0.0005^2 +5x - 500[/tex]

Step-by-step explanation:

We have price (P) = [tex]-0.0002x + 9[/tex]

to calculate Total revenue (TR) we have to multiply Price by Production quantity.

[tex]TR=P * X[/tex]   , we denote production quantity with the letter X.

[tex] TR=(-0.0002x + 9)*x[/tex]  

We apply distributive law and then we have:

[tex] TR=-0.0002x^2 + 9x[/tex]  , this is the Total revenue (TR) of selling X amount of production at a P price.

Now we only have to find the Profit (PT) using the formula:

[tex]PT=TR - TC[/tex]  , TR is total revenue and TC is total cost

The expression of the daily profit (PT) for the manufacturer is:

[tex] PT=-0.0002x^2 + 9x - (0.0003x^2 + 4x + 500)[/tex]

[tex] PT= - 0.0002^2 + 9x -0.0003^2 -4x -500[/tex]

[tex]PT =-0.0005^2 +5x - 500[/tex]

The daily profit for the manufacturer, given by P, is equal to -0.0005x^2 + 5x - 500, where x represents the number of rackets manufactured and sold each day.

In this example, the manufacturer's daily profit, P, is given by the difference between the total revenue and the total cost. The total revenue is found by multiplying the price of each racket, p , by the number of rackets sold daily, x. i.e, px. The total cost is given by the equation 0.0003x^2 + 4x + 500. Thus, the daily profit is P = (px) - (0.0003x^2 + 4x + 500). Substituting the expression for p gives P = [(−0.0002x + 9)x] - (0.0003x^2 + 4x + 500), which simplifies to P = - 0.0002x^2 + 9x - 0.0003x^2 - 4x - 500. Further simplification leads to P = -0.0005x^2 + 5x - 500. Therefore, the daily profit for the manufacturer is given by P = -0.0005x^2 + 5x - 500.

Gn= 36(1/3)^n-1, then, substitute the values of n as 1,2,3,4 and 5 to get the values of G1,G2,G3,G4 and G5 respectively.

G1=36(1/3)^1-1 = 36

G2= 36(1/3)^2-1= 12

G3= 36(1/3)^3-1 = 4

G4= 36(1/3)^4-1 = 4/3

G5= 36(1/3)^5-1=4/9

Answer:

36, 12, 4, 4/3, 4/9.

Step-by-step explanation:

We find each term by substituting the sequence number.

So the first term (where n = 1)

= 36(1/3)^(1-1)

=  36(1/3)^0

=  36 * 1

= 36.  

The second term is 36(1/3)^(2-1)  = 36 * 1/3

= 12.

We can  find subsequent terms by just multiplying the previous term by 1/3 so the third term = 12 * 1/3 = 4.

So the first 5 terms are   36, 12, 4, 4/3, 4/9.

Answer:

  $2300

Step-by-step explanation:

The commission earned by the representative is ...

  commission = 0.02 × $15,000 = $300

so the total to be paid to the sales representative is ...

  salary + commission

  = $2000 +300 = $2300
