Which of the following functions gives the length of the base edge, a(v), of a right square pyramid that is 8 inches tall as a f

Reil [10]

Answer:

$\large\boxed{a(V)=\sqrt{\dfrac{3V}{8}}}$

Step-by-step explanation:

The formula of a volume of a square pyramid:

$V=\dfrac{1}{3}a^2h$

a - base edge

h - height of a pyramid

We have H = 8in.

Substitute and solve for a:

$\dfrac{1}{3}a^2(8)=V\\\\\dfrac{8}{3}a^2=V\qquad\text{multiply both sides by}\ \dfrac{3}{8}\\\\\dfrac{3\!\!\!\!\diagup^1}{8\!\!\!\!\diagup_1}\cdot\dfrac{8\!\!\!\!\diagup^1}{3\!\!\!\!\diagup_1}a^2=\dfrac{3}{8}V\\\\a^2=\dfrac{3V}{8}\Rightarrow a=\sqrt{\dfrac{3V}{8}}$

A train covers a distance of 80 miles in 2 hours. At this rate, about how many hours will it take to cover a distance of 200 mil

Vadim26 [7]

Let's write miles over hours
80 / 2 = 200/ x
cross multiply
80x = 400
divide both sides by 80
x = 5

It will take 5 hours to cover 200 miles

Hope this helps :)

If the spray paint costs approximately $1.50 per foot of coverage, how much should the coach budget for the spray paint?

torisob [31]

Since the cost of the spray paint is approx $1.50,

The range for the cost of the spray paint is'

$\pm0.05\text{ dollars}$

Therefore, the coach budget should be between,

$\begin{gathered} \text{for }+0.05\text{ dollars,} \\ =1.5+0.05=1.55\text{ dollars and,} \\ \text{for -0.05 dollars,} \\ =1.5-0.05=1.45\text{ dollars} \end{gathered}$

Hence, the budget of the coach should be between $1.45 and $1.55.
