Step-by-step explanation:
The volume of a cone can be derived by writing an expression that represents the volume of one cone within the cylinder.
the expression for the volume of a cylinder is
the volume of a cone is a part of the volume of a cylinder
Hence the volume of a cone can be derived by dividing the volume of a cylinder by 3
Jan > Eli per hour. The slope is the rate per hour, which is almost 6, but Jan only has 20/4 = 5
No. We claim that
and use algebra to prove the statement.
Let
. Multiply this by ten to get
. Subtract the initial equation to give
and divide by
to see that
. Substituting into the original equation gives
, proving the desired statement.
It is Rong the answer is 2
