I think the answer is 15, because 5 divided by 2 is 2.5. 2.5 times 6 is 15
900=(1/2)*b*10*15
1800=150b
b=12
I hope you can figure out FC with this info.
Given:

To find:
Which statement are true?
Solution:
Option A: The entire expression is a sum.
It is true because it performed addition operation.
Option B: The coefficient of s is 3.

It is not true because the coefficient of s is
.
Option C: The term
is a quotient.
If we divide 7 by r, we obtain a quotient.
So it is true.
Option D: The term
has a variable.
It is not true because it does not contain any variable.
Therefore the entire expression is a sum and the term
is a quotient are true statement.
The answer is 705.6 cm^3.
Remember that volume of a box, rectangular prism, is: V = LWH.
So, V = 7(9)(11.2) = 705.6 cm^3
