The wheels on a car have a diameter of 28 inches. How many full revolutions will the wheels need to make to travel 200 feet?

rodikova [14]

Here we're interested in the circumference: C = pi*d. In this case C = 3.14*(28 inches) = 88 inches.

Now divide this 88 inches into 200 feet to get the # of revolutions ncessary to travel 200 feet.

200 feet 12 in
------------ * --------- = 2400 inches
1 1 ft

2400 inches
----------------------- = 27.2 revolutions (answer)

In the table below, y varies inversely as x. What is the missing value?

Minchanka [31]

Answer:

<h2>The value of y is 0.5, so the answer is C.</h2>

Step-by-step explanation:

Find first the constant of variation.

Given: x = 3, y = 4

Find: k = ?

Formula:

$y = \frac{k}{x}$

Solution:

$y = \frac{k}{x} \\ 4 = \frac{k}{3} \\ 12 = k$

Then, find the value of y in the third box.

Given: x = 24, k = 12

Find: y = ?

Formula:

$y = \frac{k}{x}$

Solution:

$y = \frac{k}{x} \\ y = \frac{12}{24} \\ y = \frac{1}{2} \\\boxed{y = 0.5}$
