Answer:
Option D. 
Step-by-step explanation:
we know that
The volume of the cylinder is equal to

In this problem we have


substitute
-----> exact value of the volume
5p = 80b
3(5p) = (80b)3
15p = 240b
Lan need 240g of butter to make fish pie for 15 people.
<h3>
Answer: 9</h3>
========================================================
Work Shown:
Apply the pythagorean theorem
a^2 + b^2 = c^2
12^2 + b^2 = 15^2
144 + b^2 = 225
b^2 = 225-144
b^2 = 81
b = sqrt(81)
b = 9
The answer is B. A reflection across the x-axis.
