Answer:
45 mph
251 ft
Step-by-step explanation:
a.)
Answer: 45 mph
b.)
Answer: 251 ft
Answer:
A = a^2.....the Area (A) of a square = a^2...where a = one side
79 = a^2...now take the sqrt of both sides, this eliminates the ^2
sqrt 79 = a
8.888 rounded = 8.89 = a......so one side = 8.89 ft

Answer:
V ≈ 714 in³
Step-by-step explanation:
The volume of a triangular prism can be found using the formula:
V = Bh, where B = the area of the base and h = the height of the prism. Since the base is a triangle, you will need to use the formula for area of a triangle: A = bh.
In this figure, the base of the triangle = 23.25 and the height of the triangle is 10.25. So, the area = ()(23.35)(10.25) ≈ 119 in²
With the B = 119 and the height of the prism = 6:
V = 119(6) = 714 in³
