Answer:
Nothing happens to the soap or the floor.
Step-by-step explanation:
"container" of soap
X^2=-80 divided by 8 both sides
X^2 =80i^2 (do you remember i^2=-1)
X=4i(square roof of 5)
First you need the formula for SA of a cylinder: SA = 2(πr^2) + 2πr*h
(area of the top and bottom circles plus the side)
Then plug your values into the equation and rearrange to make h the subject:
1470.3 = 2π13^2 + 2π*13*h
26πh = 1470.3 - 338π
h = (1470.3 - 338π)/26π
=5.00042...
so h is approximately 5 units :)
4/5 recommend, so about 4/5(120) = 96 doctors recommend the brand.
He should take them out at 9:20.
Hope this helps!
