10. Suppose you want to buy concrete for a

36 ft by 24 ft by 9 in. patio. If concrete costs

$55/yd', how much will the concrete for the

patio cost?

$1430

Step-by-step explanation:

1. Convert feet to yard

     36ft=12yd

     24ft=8yd

      9inch=.25yard

2.We need to find the volume

 v=12*8*0.25

 v=26yards³

cost=26*55=$1430

the answer is:

the answer is:

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!
