x=4, because 10+(4*2)=10+8=18 and since it is a rectangle the sides are the same.
Volume is base * height
Volume is hence 24 in * 6 in
Which gives you 144 in
Volume is 144in^3 (144 in cubed)
68% is around 70%
70% of 1 is 0.7
0.7'*3=2.1
Hope this helps :)
Answer:
D) -2
Step-by-step explanation:
to identify the slope of a line written in slope-intercept form, it would be
the coefficient of the 'x' term
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
