Answer:

y=1/3x+4

Step-by-step explanation:

y=mx+b

(0,4) and (-4,-8)

use the slope formula to find the slope between these two points:

(-4-0)/(-8-4)

the slope is 1/3.

y=1/3x+b

plug in one of the points. I used (0,4).

4=1/3(0)+b

4=b

y=1/3x+4

Alecia builds a box in the shape of a cube with an open top. She plans to paint the box. Alecia calculates that there are 256 sq

STALIN [3.7K]

Answer:

See Explanation

Step-by-step explanation:

The question is incomplete, as the options to select the required condition from were not listed. So, I will answer on general terms

From the question, we understand that the cube has an open-top and the surface ares is 256 in^2

Let L represents the edge length, the surface area (S) is:

$S = 5L^2$

Substitute 256 for S

$256 = 5L^2$

Divide both sides by 5

$51.2 = L^2$

Take square roots of both sides:

$\sqrt{51.2} = L$

$7.155= L$

$L=7.16in$ ---- approximated

The volume of the cube is:

$Volume = L^3$

$Volume = \sqrt{51.2}^3$

$Volume = 366.3573$

$Volume = 366.36in^3$

So, the edge length of the cube is 7.16 inches and the volume is 366.36 cubic inches

A particular style of jacket costs the retailer $85 per jacket. At what price should the retailer mark them so he can sell them

postnew [5]

Answer:

$130

Step-by-step explanation:

Cost = 85

To make 30% profit, he would need to sell them at:

85 + (0.3)(85) = 110.5

Now, he would need to sell them at 110.5 AFTER giving a 15% discount. So essentially we are asking, "What number discounted (decreased) by 15% would give us 110.5??"

We can let that price be x and write the equation:

x - (0.15)(x) = 110.5

x - 0.15x = 110.5

0.85x = 110.5

x = 110.5/0.85 = 130

The retailer should mark the jacket at $130
