Answer:
10.5 hours.
Step-by-step explanation:
Please consider the complete question.
Working together, two pumps can drain a certain pool in 6 hours. If it takes the older pump 14 hours to drain the pool by itself, how long will it take the newer pump to drain the pool on its own?
Let t represent time taken by newer pump in hours to drain the pool on its own.
So part of pool drained by newer pump in one hour would be
.
We have been given that it takes the older pump 14 hours to drain the pool by itself, so part of pool drained by older pump in one hour would be
.
Part of pool drained by both pumps working together in one hour would be
.
Now, we will equate the sum of part of pool emptied by both pumps with
and solve for t as:








Therefore, it will take 10.5 hours for the newer pump to drain the pool on its own.
So you divide 22. 44 by 6 it will be 3.74 . See image for steps
On a number line, you would find -1, then count to the left 6 spaces and you would get -7
X = -5 . I used photomath to solve this so it should be correct, hope this helps

Answer:</h2>
The volume of the cone in terms of π is:
A. 392π in³
<h2>
Step-by-step explanation:</h2>
The radius of the cone i.e. r is: 7 in.
and the slant height of the cone i.e. l=y=25 in.
and let h=x be the height of the cone.
Now, using the Pythagorean Theorem we have:

Hence, we get:

Now, the volume of the cone is given by:

Hence, the answer is: Option: A
