A carpenter wants to build a rectangular box with square sides in which to put round things. the material for the bottom costs $

alexira [117]

Answer: $1.627\times 1.627\times 1.88\ ft^3$

Step-by-step explanation:

Given

Suppose side face have a dimension of l\times l

and width of h

volume $V=l^2\cdot h$

$h=\frac{V}{l^2}$

volume $V=5 ft^3$

Area of side wall is $A_s=l^2$

Area of top Wall $A_t=l\times h$

Area of bottom $A_b=l\times h$

Cost of bottom wall $c_b=20\times l\times h=20lh$

Cost of top wall $c_t=50\times l\times h=50lh$

Cost of side walls $c_s=4\times l^2\times 10=40l^2$

total cost $C=c_s+c_t+c_b=20lh+50lh+40l^2$

$C=70lh+40l^2$

$C=70\times l\times \frac{5}{l^2}+40l^2$

differentiate C w.r.t l to get minima or maxima

$\frac{\mathrm{d} C}{\mathrm{d} l}=0$

$-\frac{350}{l}+80l^2=0$

$l^3=\frac{350}{80}$

$l=1.627 ft$

$h=\frac{5}{2.648}$

$h=1.88 ft$

Dimension of Box is $1.627\times 1.627\times 1.88\ ft^3$

A baker puts 5 cups of fruit into each pie he bakes. he pays $0.75 for 1 cup of fruit and $2.50 for the pie crust. He sells each

kirill [66]

Answer:

He earn $40

Step-by-step explanation:

To solve this problem, we first have to calculate how much it spends to make each pie

cups of fruit = 5

5 * $0.75 = $3.75

This means that per pie he spends $ 3.75 on cups of fruit and $ 2.50 on pie crust

If we add them together we will get how much he spends for each pie

$3.75 + $2.50 = $6.25

Now to the price that the pie sells we subtract this value to know how much you earn for each pie

$10.25 - $6.25 = $4

if he sold 10 pies we multiply this number by 10 and we will get his total profit

$4 * 10 = $40

He earn $40
