Answer:
f
Step-by-step explanation:
It would be D.
First of all, consider one side of a cube as x. If x is raised to the third, it would equal the area of that cube, maybe y. For example, if the side of a cube was 10 m and you had to find the volume of that cube, 10^3= 10x10x10= 1000 m^3.
For this problem, you just have to reverse the process. Instead of cubing a side to find the volume, take the third root of the volume to get the side length. So, if y is the volume of a cube, take the third root of y which could equal x. If you were to relate it the previous example, 1000 is the volume. So, <span>³√1000= 10.
Therefore, to find the side length of a cube with volume 125m^3, you would have to </span><span>³√125m = 5.</span>
Answer:
20
Step-by-step explanation:
The triangles are similar so we can use ratios
8 32
--- = -----
8+5 32+x
Using cross products
8(32+x) = 32(13)
Divide each side by 8
(32+x) = 32(13)/8
32+x = 4*13
32+x =52
Subtract 32
x = 20
To find the amount she makes per hour, divide the total amount she made by the number of hours she worked:
225 / 18 = 12.5
This means she made $12.50 per hour.
