Answer:
C: ![-7ab \sqrt[3]{3ab^{2} }](https://tex.z-dn.net/?f=-7ab%20%5Csqrt%5B3%5D%7B3ab%5E%7B2%7D%20%7D)
Step-by-step explanation:
Simplify or expand:
![2ab\sqrt[3]{192ab^{2} } - 5\sqrt[3]{81a^{4} b^{5} }](https://tex.z-dn.net/?f=2ab%5Csqrt%5B3%5D%7B192ab%5E%7B2%7D%20%7D%20-%205%5Csqrt%5B3%5D%7B81a%5E%7B4%7D%20b%5E%7B5%7D%20%7D)
Transform the expression:
- ![5\sqrt[3]{3^{3}*3a*ab^{3} b^{2} }](https://tex.z-dn.net/?f=5%5Csqrt%5B3%5D%7B3%5E%7B3%7D%2A3a%2Aab%5E%7B3%7D%20b%5E%7B2%7D%20%20%7D)

Multiply
Combine like terms.
First, we need to find his unit rate, the amount he earns in 1 hour.
So, we have to divide 28.50 by 2.
That is:
28.50 / 2 = $14.25 per hour
To find the amount he earns in 8 hours, we will need to multiply hourly rate found by "8". So,
14.25 * 8 = $114
<h2>Rolando earns $114 in 8 hours</h2>
Volume = (Area of the base)x(Height)
66.85 = 15(H)
66.85/15 = H
H = 4.4567
The height is 4.4567mm.
