Answer:
4.63 cubic yard.
Step-by-step explanation:
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.
Answer:
I think the width would be 7.5
Step-by-step explanation:
25 x 18 = 450
450/60 = 7.5
Therefore the width is 7.5
Sorry if wrong hope this helped and pls mark brainliest!
Step-by-step explanation:
using trig, tangent is equal to opposite over adjacent.
in this case, the angle is 45, opposite is 7, and adjacent is a.
thus tan 45° = 7/a
solve for a to get a = 7/tan 45° = 4.32
Answer:
14
Explanation:
The constant of proportionality is 14, when we divide all of the y values by all of the x values, we get 14.
hope this helps!
