Ahomeowner has decided to fill in his in-ground pool because it is no longer used assume the pool is rectangular and measures 20 ft wide 40 ft long and 5.5 ft deep throughout each cubic yard of fill dirt cost $12 how much will it cost to fill the pool assume that you must purchase for cubic yards only

So for this problem we need to find the volume. The formula for volume is

l * w * h

40 * 20 * 5.5 = 4400

So now you need to put ft into yards

4400ft = 1466.667

Now multiply this by 12

1466.667 * 12 = 17600.004

Because you cant have $00.004 I believe that for this equation you would round to the nearest hundred, so that would be $17600.01.

Your answer is $17600.01

option 1 is correct.

step-by-step explanation:

y varies inversely with x and constant of variation is 4

the equation will be:

y = k/x

where k =4 so,

y = 4/x

if we put values of x of option 1 in the above equation and find values of y

y = 4/-2 => y =-2

y = 4/-1 => y = -4

y = 4/1 => y = 4

y = 4/2 => y =2

so, all the values of x and y are correct.

if we put values of x given in other options and find value of y we cannot find whole table satisfying the equation.

hence option 1 is correct.
