You find the overall change in temperature by adding them together.
-8 would be from were is decreased 8 degrees and +8 would be from where it increased 8 degrees
Like: -8+8=0
Answer:
10
Step-by-step explanation:
Assuming that each square is one unit, you plug it into the distance formula.
A is the answer Bc I did this before and my teacher said I did an excellent job!
A circular concrete slab is a cylinder. Vol = pi%2Ar%5E2%2Ah
in this cylinder:
r = 18%2F2 = 9 ft
h = 3%2F12 = .25 ft
:
Find the volume in cu/ft:
V = pi%2A9%5E2%2A.25
V = 63.61725 cu/ft
:
Change to cubic yds; (1 cu/yd = 27 cu/ft) and multiply by $40:
Cost = 63.61725%2F27 * 40
Cost = $94.25
In practical terms , they may require you to buy 3 cu/yds , which is $120
