Matt plans to put concrete on a rectangular portion of his driveway. the portion is 8 feet long and 4 inches high. the price of concrete is $98 per cubic yard. the total cost of the concrete matt needs is $58.07. which of the following is closest to the width of the portion of the driveway on which matt plans to put concrete?

[1 foot = 12 inches; 1 yard = 3 feet]

0.5 feet

1.5 feet

3 feet

6 feet

Hi,
   
1 cubic yard = 27 cubit feet
 
Then we must find the no. of cubic yards for 1 cubic yard = $98 for "x" cubic yard = $58.07 1/x =98/58.07 x = 0.5925
 
Now we have to convert this in to cubic feet... 1 cubic yard = 27 cubic feet 0.5925 cubic yard = x cubic feet 1/0.5925= 27/x x = 15 .99

cubic feet now width x height x length = 16 cubic feet w x 8 x (1/3) = 16 w = 48/8 = 6 feet yep!

there for the width of the yard is approximately 6 feet.. hope this will help ya !

What’s the equation you are trying to solve to get x?

Hello!

the answer is:

the answer is:

why?

to solve the problem, we need to remember the quotient of power property, it's defined by the following relation:

if we have a quotienf of powers that have the same base, we need to keep the same base and subtract the exponent of the denominator power to the exponent of the numerator power.

so, we are given the expression:

then, calculating we have:

hence, the answer is:

have a nice day!
