Answer:
The volume of the water in the pool is 1,017 cubic feet
Step-by-step explanation:
we know that
The volume of a cylinder is equal to
we have
----> the radius is half the diameter
Remember that
so
To find out the height of the water, subtract 0.5 feet from the height of the swimming pool
assume
Find the volume of the water
-2n + 9mn - 17np
All you do is simplify the equation by distributing and multiplying the 1/3n to each of the numbers.
Hope this helps!
The answer is given by the
second choice: letter B. 14.75 is the answer because to get the mean, you
should add all the numbers and then divide it by how many numbers there are.
For example, in this case, you add 12, 17, 16, 10, 20, 13, 14, 14, 12, 12, 19,
18 to each other. You will get the answer 172. After that, you should
divide 172 by 12 because there are 12 numbers in the data set.
Since u brought up the 15 combining like terms it would be 4+15 which =19 and the bottom bringing 2x down makes it -2x so (3x+x^2+2x-2x) would =3x^2 (three x squared)
