The cost of renting a car is $85/wk plus $0.15/mi traveled during that week. An equation to represent the cost would be y = 85 +
meriva

Answer:

I was being charged for 65 miles

Step-by-step explanation:

Given

y = 85 + 0.15x

Required

Find x when y = 94.75

Substitute 94.75 for y in y = 85 + 0.15x

94.75 = 85 + 0.15x

Collect Like Terms

0.15x = 94.75 - 85

0.15x = 9.75

Solve for x

x = \frac{9.75}{0.15}

x = 65\\

The height and weight of adults can be related by the equation y=48.3x−127 where x is height in feet and y is weight in pounds.
suter [353]

we conclude that the correct option is A, the slope is:

<em>"the average number of pounds per foot tall"</em>

<h3>What does the slope of the line represent?</h3>

The linear equation:

y = 48.3*x - 127

Relates the height, x, and the weight, y of an adult.

Then the slope, which is 48.3, should have units of mass over height.

Now, if x is in feet and y is in pounds, then the slope has units of pounds/feet.

Then it represents the mean number of pounds per feet. So we conclude that the correct option is A:

"the average number of pounds per foot tall"

They are going to build wind turbines off the coast of Staten Island. It requires ⅙ square miles of land. How many turbines can
Mila [183]

Answer:

48

Step-by-step explanation:

Here we will show you how to calculate 8 divided by 1/6. We will give you the answer in fraction form and in decimal form.

Here is 8 divided by 1/6 displayed mathematically in colors:

8

 ÷    

1

6

The numbers in 8 divided by 1/6 are labeled below:

8 = whole number

1 = numerator

6 = denominator

To make it a fraction form answer, you multiply the whole number by the denominator and make the result the new numerator. The old numerator becomes the new denominator:

8 x 6

1

 =  

48

1

Thus, the answer to 8 divided by 1/6 in fraction form is:

48

1

To make the answer to 8 divided by 1/6 in decimal form, you simply divide the numerator by the denominator from the fraction answer above:

48 / 1 = 48

The answer is rounded to the nearest two decimal points if necessary.

48/1 is an improper fraction and should be written as 48.

Answer:

Check the figure a for the complete solution.

<em>Translation in Portuguese:</em> Verifique a figura a para a solução completa.

Step-by-step explanation:

Complete os espaços com os números da tabela, de forma que a soma dos valores em todos os círculos seja zero.

Como

5 +  (-2) + (-3) = 5 - 2 - 3 = 0

10 + (-2) + (-8) = 10 - 2 - 8 = 0

0 + (-8) + (8) = 0 - 8 - 8 = 0

-11 + 3 + (8) = -11 + 3 + 8 = 0

-9 + 3 + (6) = -9 + 3 + 6 = 0

-15 + (9) + (6) = -15 + 9 + 6 = 0

-15 + (5) + (10) = -15 + 5 + 10 = 0

-7 + (10) + (-3) = -7 + 10 - 3 = 0

Check the figure a for the complete solution.
