Answer:
10/3 hours
Step-by-step explanation:
12x=15x-10
12x-15x=15x-10-15x
-3x=-10
-3x/-3=-10/-3
x=10/3
The domain { x | x = -5 , -3 , 1 , 2 , 6}
You can use calculus ( related rates). Given the rate os change of the radius for example you can find the rate of change of volume using differential calculus.
The last one is correct because 60+35+35+35=165
55+55+55=165
At least about 20 points it can depend on the class but not really.
