The correct answer is C. So, lets go first to the equations that determine the volume of these solids. For the cylinder, that is simple; pi*r*r*h where r is the radius, h is the height and pi is the constant 3.14. For the cone, it is not easy to derive but one gets that the formula is:
.
We notice thus that
. That holds irrespective of their radius or height; we only need to know that the heights and radii of the two objects are the same. Now, we have thus that:
.
We can check if this holds for Jared's statement; 1178/4712=0.25=1/4. So, it does not hold and thus Jared's statement is incorrect.

Answer:
b) (5, -3)
Step-by-step explanation:
The given equations are;
I prefer using substitution because of the first equation.
Put equation (1) into equation (2) to obtain;
We expand the parenthesis to obtain;
Group similar terms to get;
Simplify
Divide through by 5;
Put into equation (1) to get;
The solution is (5,-3).
The correct answer is B
Answer:
-8 to the power of 0 = 1
(Anything to the power of 0 = 1)
and 6 to the power of -1 = 1/6
( Any number to the power of a negative number will become a fraction)
Example.
So is will be 1/6 over 1
Which gives you your final answer.
