solniwko [45]

Answer:

Step-by-step explanation:

Given :

|x – 72.5| = 4.

|x - 72.5| = 4\\it\  can \ be \ written \ as \\72.5-x=4\\-x=4-72.5\\x=68.5

When the Temperature of x is maximum So the Maximum Temperature is

A driveway 18 ft wide and 36 ft. long is to be paved with concrete 3 in. thick. How many cubic yards of concrete are required?
amm1812

Answer:

6 yds^3

Step-by-step explanation:

I find these easiest if you put all of the dimensions into yards and then multiply

18 ft =  6 yds

36 ft = 12 yds

3 in = 3/36 yds    = 1/12 yds     now multiply them together

6 x 12 x 1/12 = 6 yds^3
