I just had the question and the correct answer is 36.
Answer:
The volume is changing at a rate given by:

Step-by-step explanation:
Let's recall the formula for the volume of acone, since it is the rate of the cone changing what we need to answer:
Volume of cone = 
where B is the area of the base (a circle of radius R) which equals = 
and where H stands for the cone's height.
We apply the derivative over time operator (
) on both sides of the volume equation, making sure that we apply the rule for the derivative of a product:

A + s = 444
s = 2a
a + 2a = 444
3a = 444
a = 444/3
a = 148 <== adults
s = 2a
s = 2(148)
s = 296 ...students
Answer:
m=2j+10
m+j=52
Step-by-step explanation:
juan = j
maria = m
m = 2j + 10
m + j = 52
