27: a patio measures 12 feet by 14 feet. how many 8-inch-square paving stones are needed to pave a patio

Otrada [13]

The side of the patio that is 12 feet is equal to 144 inches. 144 inches divided by 8 inches for each stone tells you that you can fit 18 stones along this edge. The side of the patio that is 14 feet is equal to 168 inches. 168 divided by 8 is 21, telling you that 21 stones fit along this edge. By multiplying the number of stones on each edge, you can find the total number of stones needed. 21 times 18 equals 378 stones to pave the whole patio.

If x varies inversely as y 2, and x = 2 when y = 20, find x when y = 5.

Dominik [7]

Step-by-step explanation:

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

x varies inversely as y. This means that x is equal to the inverse of y which can be translated as x = 1/y but the problem said that x is not exactly equal to the inverse of y. Therefore, we need to introduce a factor k. Factor k will represent the word "varies" in the problem.

To illustrate:

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

Since we don't have the value of k, we have to solve for it by using the first values of x and y which was given as x=2 and y=20.

$x = \frac{k}{y} \\ 2 = \frac{k}{20} \\ k = 2(20) = 40$

Now that we have the value of k, we can now solve for the value of x when y=5.

$x = \frac{k}{y} \\ = \frac{40}{5} \\ = 8$

Therefore, when y is 5, the value of x is 8.
