I think the answer is 2.7 hours

Using the formula Time = Distance ÷ Speed, we find that the driver would spend approximately 1.67 hours on the first 100 miles and 0.91 hours on the last 50 miles. Adding these two times gives a total travel time of approximately 2.58 hours.

The first thing you need to do is calculate the time spent in each part of the trip. To calculate time, we use the formula Time = Distance ÷ Speed. For the first 100 miles at 60 mi/h, it takes: Time = 100 miles ÷ 60 mi/h = 1.67 hours. Moving on to the next 50 miles at 55 mi/h, it takes: Time = 50 miles ÷ 55 mi/h = 0.91 hours.

Adding these two times together gives us the total time for the trip: 1.67 hours + 0.91 hours = 2.58 hours. So, the driver would take approximately 2.58 hours to reach his destination if he traveled 100 miles at 60 mi/h and the remaining 50 miles at 55 mi/h.

Note that RT is the whole line segment, and RS and ST are parts of it

RS = 6y + 5

ST = 2y - 3

RT = 12y - 14

Set the equation

RS + ST = RT

(6y + 5) + (2y - 3) = 12y - 14

Simplify. Combine like terms

6y + 2y + 5 - 3 = 12y - 14

(6y + 2y) + (5 - 3) = 12y - 14

8y + 2 = 12y - 14

Note the equal sign. What you do to one side, you do to the other. Isolate the variable (y). Subtract 12y from both sides, and 2 from both sides.

8y (-12y) + 2 (-2) = 12y (-12y) - 14 (-2)

8y - 12y = -14 - 2

Simplify. Combine like terms

(8y - 12y) = (-14 - 2)

-4y = -16

Isolate the y. Divide -4 from both sides

-4y/-4 = -16/-4

y = (-16)/-4

y = 4

Answer:

42.7716% of the variation in the number of bags of trash collected can be explained by differences in the number of volunteers.

Step-by-step explanation:

The correlation coefficient (r) between the number of volunteers x and the number of bags of trash collected y is 0.654

For finding the percent of the variation in one variable explained by the other variable, we just need to take square of the correlation coefficient.

Here,  [tex]r=0.654[/tex]

So,  [tex]r^2 = (0.654)^2 = 0.427716[/tex]

Now, for converting it into percentage, we will multiply it by 100.

So, [tex]0.427716*100\% = 42.7716 \%[/tex]

Thus, 42.7716% of the variation in the number of bags of trash collected can be explained by differences in the number of volunteers.

Final answer:

About 42.8% of the variation in the bags of trash collected can be attributed to the number of volunteers, as indicated by the squared correlation coefficient (0.654²).

Explanation:

The correlation coefficient (r) measures the strength and direction of a linear relationship between two variables. When squared to calculate the coefficient of determination (r²), it represents the proportion of the variance in the dependent variable that is predictable from the independent variable. In the given scenario, with a correlation coefficient of 0.654, the coefficient of determination would be 0.654², which calculates to approximately 42.8%. This percentage indicates that about 42.8% of the variation in the number of bags of trash collected (y) can be explained by the variation in the number of volunteers (x).

Given

One month julia collected 8.4 gallons of rainwater.

she used 5.2 gallons of rainwater to water her garden

6.5 gallons of rainwater to water flowers

Find out how much was the supply of rainwater increased or decreased by the end of the month.

To proof

As given in the question

One month julia collected 8.4 gallons of rainwater

she used 5.2 gallons of rainwater to water her garden and 6.5 gallons of rainwater to water flowers

Total water she used in the month = 5.2 gallons + 6.5gallons

                                                         = 11.7 gallons

Let the supply of rainwater increased or decreased by the end of the month

be x .

Than the equation become in the form

x + 8.4 = 11.7

x = 3.3 gallons

Therefore the supply of rainwater increased or decreased by the end of the month is 3.3 gallons.

Hence proved

Total rainwater collected by Julia = 8.4 gallons

Water used for watering garden = 5.2 gallons

Water used for watering flowers = 6.5 gallons

Hence, total water used by Julia = [tex]5.2+6.5=11.7[/tex] gallons

11.7 gallons were used and only 8.4 gallons were collected , so supply of rainwater decreased by [tex]11.7-8.4=3.3[/tex] gallons

To find the height of the original oil tank from the sample, you set up a proportion using the scale given. The calculation shows that the original tank is 25 meters tall, corresponding to answer A.

The question is asking us to find the height of the original oil tank given that the sample tank is [tex]\frac{1}{25}th[/tex] the size of the original and that the sample is 1 meter tall. Since the sample is a scaled-down version of the original, we can set up a proportion to find the original height.

To set up the proportion, we assume the scale is such that 1 meter on the sample represents 25 meters on the original. Therefore, we can write the proportion as:

[tex]\frac{1\ meter}{ x\ meters} = \frac{1}{25}[/tex]

We can then cross-multiply to solve for x:

1 * x = 25 * 1

x = 25 meters

Thus, the height of the original oil container tank is 25 meters, which corresponds to answer choice A.

Answer:

The required number of bowls are 5.  

Step-by-step explanation:

Given : A sugar bowl holds 237 grams. You have a one kilogram bag of sugar.

To find : Estimate how many bowls of sugar you can fill from the bag?

Solution :

1 bowl can hold 237 gram of sugar.

We have, 1 kg of sugar or 1000 gram of sugar.                

According to question,

237 gram of sugar can hold in 1 bowl.

So, 1 gram of sugar can hold in [tex]\frac{1}{237}[/tex] bowl.

1000 gram of sugar can hold in [tex]\frac{1000}{237}[/tex] bowl.      

1000 gram of sugar can hold in [tex]4.21[/tex] bowl.  

Which means, The required number of bowls are 5.

As 4 bowls have [tex]237\times 4=948[/tex] grams of sugar.

Sugar left is 1000-948=52 grams

That 52 grams is filled into 5th bowl.

A Pythagorean triplet is a set of 3 positive integer numbers which may be the sides of a right triangle, i.e. they meet the Pythagorean theorem c² = a² + b².

You can check that the numbers on your table are Pythagorean triplets by substituting them in the Pythagorean equation:

Now, lets look for the pattern:

x-value     Pythagorean

                 triple    

3               (6, 8, 10)              6/2 = 3

                                            3² - 1 = 9 - 1 = 8

                                            3² + 1 = 9 + 1 = 10

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

4               (8, 15, 17)              8/2 = 4

                                             4² - 1 = 16 - 1 = 15

                                             4² + 1 = 16 + 1 = 17

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

5               (10, 24, 26)              10/2 = 5

                                                 5² - 1 = 25 - 1 = 24

                                                 24² + 1   = 25 + 1 = 26

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

6               (12, 35, 37)              12/2 = 6

                                                6² - 1 = 36 - 1 = 35

                                               6² + 1   = 36 + 1 = 37

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

From which you find the pattern: the first number is 2x, the second number is x² - 1, and the third number is x² + 1

                                            ⇒ (2x)² + (x² - 1)² = (x² + 1)², or

                                                (x² - 1)² + (2x)² = (x² + 1)².

Other example of a Pythagorean triple is (3, 4, 5). You migth think that it does not follow the pattern, but if you do x = 2, you end with:

Hence, (3, 4, 5) also follows the pattern.

Only  right triangles with non-integer sides do not form Pythagorean triples.

Of course you may proof that (x² - 1)² + (2x)² = (x² + 1)² is an identity (always true):

Left hand side: (x⁴ - 2x² + 1) + 4x² = x⁴ + 2x² + 1

Right hand side: x⁴ + 2x² + 1

∴ The equation is always true.

At the end, the pattern is true for any Pythagorean triplet, but a more formal proof is beyond the scope of this question.

ANSWER

The correct answers are option B and C

EXPLANATION

A linear function with slope [tex]m=1[/tex] and y - intercept [tex]0[/tex] has equation, [tex]f(x)=x[/tex]

Option A

[tex]f(-1)=-1[/tex]

[tex]g(-1)=(-1)^2=1[/tex]

Therefore [tex]f(-1) \ne g(-1)[/tex]

Option B

[tex]f(1)=1[/tex]

[tex]g(1)=(1)^2=1[/tex]

Therefore [tex]f(1) = g(1)[/tex]

Option C

[tex]f(0.5)=0.5[/tex]

[tex]g(0.5)=(0.5)^2=0.25[/tex]

Therefore [tex]f(x) > g(x)[/tex]

on [tex](0,1)[/tex] See graph also.

Option D

At y-intercept, [tex]x=0[/tex]

This implies that,

[tex]f(0)=0[/tex]

[tex]g(0)=(0)^2=0[/tex]

Therefore g(x) does not have a greater y-intercept.

The function f(x) with a slope of 1 and a y-intercept of 0 is compared with the quadratic function g(x)=x^2. f(1) is equal to g(1) and f(x) is greater than g(x) on the interval (0,1).

The function g(x)=x^2 is a quadratic function, and the function f(x) with a slope of 1 and a y-intercept of 0 is a linear function. Let's evaluate the given statements:

In summary, the true statements are: f(1) is equal to g(1), and f(x) is greater than g(x) on the interval (0,1).

answer is (-7,2)

y = -x -5

y= x+9

Both equations have y on the left hand side

So we equate both equations

We replace -x-5 for  y in the second equation

-x -5 = x+9

Subtract x on both sides

-2x -5 = 9

Now add 5 on both sides

-2x = 14

Divide by -2 from both sides

x = -7

Now plug in -7 for x in the first equation

y = -x -5

y = -(-7)  -5= 7-5 = 2

Answer

−5a⁴(2a²+4)=−10a⁶−20a⁴ is correct.

−4x²(2x²+5)=−8x⁴−20x²  is correct.

−6y⁴(4y²+2)=−24y⁸−12y⁴ is NOT correct.

−4b³(5b²+3)=−20b⁶−12b³  is NOT correct.

Explanation

Equation 1

−5a⁴(2a²+4)=−10a⁶−20a²    ⇒ −5a⁴(2a²+4) = ( −5a⁴×2a²)+ ( −5a⁴×4)

                                                                      = -10a⁶ - 20a⁴

−5a⁴(2a²+4)=−10a⁶−20a² is correct

Equation 2

−4x²(2x²+5)=−8x⁴−20x²        ⇒   −4x²(2x²+5) = (-4x²×2x²) + (-4x²×5)

                                                                           = -8x⁴ - 20x²

−4x²(2x²+5)=−8x⁴−20x²  is correct.

Equation 3

−6y⁴(4y²+2)=−24y⁸−12y⁴     ⇒ −6y⁴(4y²+2) =  (−6y⁴×4y²) + (-6y⁴×2)

                                                                       = -24y⁶ - 12y⁴

−6y⁴(4y²+2)=−24y⁸−12y⁴ is NOT correct.

Equation 4

−4b³(5b²+3)=−20b⁶−12b³       ⇒ −4b³(5b²+3) = (−4b³×5b²) + (-4b³×3)

                                                                           = -20b⁵ - 12b³

−4b³(5b²+3)=−20b⁶−12b³  is NOT correct.                                        

y = - [tex]\frac{3}{4}[/tex] x  - [tex]\frac{7}{2}[/tex]

the equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

to calculate m use the gradient formula

m = ( y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (- 6, 1 ) and (x₂, y₂ ) = (2, - 5 )

m = [tex]\frac{-5-1}{2+6}[/tex] = [tex]\frac{-6}{8}[/tex] = - [tex]\frac{3}{4}[/tex]

the partial equation is

y = - [tex]\frac{3}{4}[/tex] x + c

to find c substitute either of the 2 given points into the partial equation

using (- 6, 1 ), then

1 = [tex]\frac{9}{2}[/tex] + c ⇒ c = 1 - [tex]\frac{9}{2}[/tex] = - [tex]\frac{7}{2}[/tex]

y = - [tex]\frac{3}{4}[/tex] x - [tex]\frac{7}{2}[/tex] ← equation of line

Answer:

5.13 feet

Step-by-step explanation:

Engine is driving the propeller with a radius of 8 feet and its centerline 13 feet above the ground.

And the speed is 700 revolutions per minute, the height of one propeller tip as a function of time is given by:

[tex]h=13+8 \sin(700t)[/tex]

We have been asked to find the value of height, 'h', when t=4 minutes.

Plugging the value of time, 't', in the equation, we already know that we need to use degrees (not radians) we get:

[tex]h=13+8 \sin (700 \times 4)[/tex]

[tex]h=13+8 \sin (2800)[/tex]

[tex]h=13+8 \times (-0.984)[/tex]

[tex]h=13+(-7.872)[/tex]

[tex]h=13-7.872[/tex]

[tex]h=5.128\approx 5.13[/tex]

So the height of one propeller tip at t=4 minutes is 5.13 feet.

The question centers on mathematics, where we calculate the number of cookies Tovah needs and explore probability and trading scenarios related to assorted cookies and resource allocation.

The subject of this question is Mathematics, particularly focusing on basic arithmetic, probability, and problem-solving. Tovah needs a total of 700 cookies and already has 300 cookies. To determine how many more cookies Tovah needs, we can subtract the number she already has from the total number needed: 700 - 300 = 400. Hence, she needs to obtain 400 more cookies.

Additionally, when discussing assorted cookies, we can delve into probability and combinatorics. For instance, if we consider a scenario with cookies containing chocolate, nuts, or both, we can calculate the probability that a certain combination is selected. This involves understanding percentages, probability trees, and independence of events.

Lastly, we can explore resource allocation and trading as seen in examples where individuals barter items like chocolate bars or Halloween candy. This introduces concepts like gains from trade and distribution of resources, which are essential to economic mathematics.
