Answer:

x=8

Step-by-step explanation:

Notice that 4 divided by itself equals one. So if you take 4 times one, it equals 4. Do the same to the 2, multiplying it by 4 making 8. It would be 8 over 4. Add the 2 zeros to the 4 and the 1 making 2/100 and 8/400.

X=8

So you have 2/100 and x/400. To solve, you must first do cross multiplication. That means you multiply x by 100 and 2 by 400. You will get 100x=800. You then simplify the equation to find out that x=8.

Ashton bought 5 cans of olive oil. Each can had a radius of 3.2 inches and was 15 inches tall. Find the total cubic inches of ol

amid [387]

Step-by-step explanation:

A can is a cylinder.

Volume of a can = Volume of Cylinder

$= \pi {r}^{2} h$

Given Radius = 3.2 inches and height = 15 inches,

Volume of one olive oil can =

$\pi( {3.2}^{2} )(15) \\ = 153.6\pi {in}^{3}$

Volume of 5 olive oil cans = 5 x volume of one olive can

$= 5 \times 153.6\pi \\ = 768\pi {in}^{3}$

I will just leave the answer in terms of pi as I'm not sure if you need to round off your answers.
