Given the proportional steel cost, how much do 200 pounds of steel cost?

Answers

Answer:

Your answer is B, 150

Step-by-step explanation:

If we look at the chart it says 160 pounds of steel is 120, so for example if we start from 40 we will have 30, so every time we add 40 pounds 30$ are added, meaning that 160+40=200, 120+30= 150, Thus B or 150 is our answer.

Answer:

$150

Step-by-step explanation:

Hi,

We know that 160Ibs of steel costs $120. To find the cost of 1Ib of steel, we have to divide both 160Ibs and $120 by 160. Here's what I mean...

Total amount: 160Ibs

Divide by 160...

Total amount: 1Ib

Total cost: $120

Divide by 160...

Total cost: $.75

That means that each pound of steel costs $.75

Now, multiply by 200 to get the total cost if you buy 200Ibs of steel...

200 x .75 = 150

The total cost would be $150

Repost the same with the picture of the graph so we can help you!

The length of side XY on the coordinate plane is 4 units.

What is distance between two points?

The distance between two points is the length of the line segment joining them.

Given that a coordinate plane, a rectangle has 4 points. Point W is (-5, 3), point X is (0, 3), point Y is (0, -1), and point Z is (-5, 0).

Distance between two points = [tex]\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

Therefore,

XY = [tex]\sqrt{(0-0)^2+(-1-3)^2}[/tex]

XY = [tex]\sqrt{4^2}[/tex]

XY = 4

Hence, the length of side XY on the coordinate plane is 4 units.

Josh said his shoe was exactly a foot long.

Answers

First step is to subtract 986 from both sides.

Step-by-step explanation:

I would subtract 986 from both sides because then it will balance out the equation; variable on one side and the number on one side. With this it will be easier to solve for n.

I would subtract 986 to each side to get 49n by itself then divide the coefficient 49n by itself to get N alone
