Answer:

Maximum Volume = 29,659.5 cubic inches

Step-by-step explanation:

We can write the perimeter as 2*(x+h) and this is equal to 117

$2(x+h) = 117\\x+h=58.5\\h=58.5-x$

The volume is $x^2(h)$

Plugging the expression for h, we have:

$V=x^2 h\\V=x^2(58.5-x)\\V=58.5x^2-x^3$

The max volume can be found when this differentiated is equal to 0, or dV/dx=0

$V=58.5x^2-x^3\\\frac{dV}{dx}=117x-3x^2=0\\3x(39-x)=0\\x=0,39$

x can't be 0, so we take x = 39

and thus h=58.5-x = 58.5-39=19.5

Max Volume = $x^2h=(39)^2 (19.5)=29,659.5$

german

Answer:

They sold 120 milkshakes that day

Step-by-step explanation:

We can set up a proportion

$\frac{48}{m} =\frac{2}{5}$

$48*5=2m\\ 2m = 240\\m = 120\\$

Note: If you have some value, $v$ , and it is $\frac{x}{100}$ of the total amount, you can find the value by doing the equation $\frac{v}{x}*100$
