The difference between the coat cost for Delaware vs Fairfield is $0.60

Explanation:
For Delaware: 80 × .0725 = $5.80
80+5.80= $85.80

For Fairfield: 80 × .065 = $5.20
80+5.20=$85.20

85.80-85.20=0.60

Suppose we want to build a rectangular storage container with open top whose volume is $$12 cubic meters. Assume that the cost o

Snezhnost [94]

Answer:265.25

Step-by-step explanation:

Given

Volume of box $=12 m^3$

height is 3 times the width

let height, length and breadth be H, L & B

$H=3\times B$

$V=12=L\times B\times H$

4=B^2\times L[/tex]

$L=\frac{4}{B^2}$

Cost of side walls $ $8/m^2$

Cost of base $ $12/m^2$

Cost of side walls $=(2LH+2BH)\cdot 8$

Cost of base $=12LB$

Total cost $C=16LH+16BH+12LB$

$C=48LB+48B^2+12LB$

$C=\frac{192}{B}+48B^2+\frac{48}{B}$

differentiate C w.r.t B to get minimum cost

$\frac{\mathrm{d} C}{\mathrm{d} B}=-\frac{192}{B^2}+2\times 48 B-\frac{48}{B^2}$

$B^3=\frac{240}{2\times 48}$

$B=1.35 m$

$H=3\times 1.35=4.07 m$

L=2.19 m

C=$ 265.25

Factor out the coefficient of the variable term.

aivan3 [116]

Given:

The expression is

$\dfrac{1}{2}n-\dfrac{1}{2}$

To find:

The factored form of given expression after factor out the coefficient of the variable term.

Solution:

We have,

$\dfrac{1}{2}n-\dfrac{1}{2}$

Here, the coefficient of variable n is $\dfrac{1}{2}$ .

It can be written as

$=\dfrac{1}{2}\times n-\dfrac{1}{2}\times 1$

Taking out $\dfrac{1}{2}$ as common factor, we get

$=\dfrac{1}{2}(n-1)$

Therefore, the factored from of given expression is $\dfrac{1}{2}(n-1)$ .
