391
Step-by-step explanation:
17 x 23 = 391
Answer:
Hence the new height is 3 times the original height .(h1=3h)
Step-by-step explanation:
Given:
A cone with has height and base with radius r .
To Find:
What is new height
Solution:
Consider as cone with height h base radius r, and volume v
Here given that only height changes for the cone i.e. r remains the unchanged or same or constant
The volume for a regular cone is given by ,

Here V is directly proportional to h i.ee pie ,3 and r being constant

i.e V/h=constant
V1 and h1 are new dimensions for new cone
V/h=V1/h1
Here V1=3V
So V/h=3V/h1
1/h=3/h1
i.e h1=3h
Hence the height is 3 times the original height .

I don't know, but I tried.
Answer: maybe 200
Step-by-step explanation: it looks like all you have did for the other ones is take 20 and multiply it by the denominator. so that is what i have done
Answer:
60 hours
Step-by-step explanation:
Let X be the total capacity.
Inlet speed: X/15
Outlet speed: X/20
Combined:
X/15 - X/20 = X/60
X/60 = X/time
Time = 60 hours
