A commercial building has seven levels of car parking spaces. Each level has four rows and each row has 38 car spaces. How many

tatyana61 [14]

So, all we have to do here is multiply:

First, the amount of car spaces by the amount of rows:

38 x 4 = 152

This is the number of parking spots per level.

Then, the number of levels by the number of parking spots on each level:

152 x 7 = 1064

So, a total of 1,064 cars can be parked in this building!

Dana walks 3/5 mile in 1/4 hour. What is dana's walking rate in miles per hour?

Flura [38]

Here, our equation is 3/5 (0.6) mile per 1/4 (0.25) hour. 0.25 times 4 = 1, so we have to multiply 1/4 (0.25) 4 times to get 1 mile. To get a proportional answer, we must also multiply 3/5 (0.6) by 4. This comes out to 2.4. So her walking rate is 2.4 miles per hour.

What are the surface area and volume of a spherical barrel cactus with a radius of 5 inches?

tino4ka555 [31]

$\bf \textit{surface area of a sphere}\\\\ SA=4\pi r^2~~ \begin{cases} r=radius\\[-0.5em] \hrulefill\\ r = 5 \end{cases}\implies SA=4\pi (5)^2 \\\\\\ SA=100\pi\implies SA\approx 314.16 \\\\[-0.35em] ~\dotfill\\\\ \textit{volume of a sphere}\\\\ V=\cfrac{4\pi r^3}{3}\qquad \qquad V=\cfrac{4\pi (5)^3}{3}\implies V=\cfrac{500\pi }{3}\implies V\approx 523.60$
