Answer: B
Step-by-step explanation:
trust me the answer is B if the answer is not reported me
Answer:
y=8/(P+q+4)
we can find out that three items have y
so we can get them together Py+qy+4y=8
next(P+q+4)y=8 so y=8/(p+q+4)
4.63 cubic yard.
Given,
The length of sidewalk, l = 100 feet,
Width, w = 5 feet,
Depth, h = 3 inches = 0.25 feet,
Thus, the volume of the concrete needed for making the sidewalk,
= 125 cubic feet,
∵ 1 cubic yard = 27 cubic feet,
⇒ 1 cubic feet = cubic yard,
Thus, the quantity of concrete needed = ≈ 4.63 cubic yard.
