M(x)=-x²+14x
m'(x)=-2x+14
set this equal to 0 and solve for x
-2x+14=0
-2x=-14
x=7
m(7)=-7²+14(7)=-49+98=49 million mosquitoes

Answer: $\frac{5}{12}$

Step-by-step explanation:

We will subtract the amount of water that leaked out from the amount of water originally in the fish tank.

$\displaystyle \frac{3}{4} - \frac{1}{3} =\frac{3*3}{4*3} -\frac{1*4}{3*4} =\frac{9}{12} -\frac{4}{12}=\frac{5}{12}$

The fish tank is $\frac{5}{12}$ of the way full.

so it's 2( 14 + 21 + 6) = 2(41) = 82
