Answer:
%12.5
Step-by-step explanation:
<em>Step 1: Make an equation</em>
<em>400x = 450</em>
<u>Step 2: Divide both sides by 400</u>
400x / 400 = 450 / 400
<em>x = 1.125</em>
<u>Step 3: Convert into a percentage</u>
1.125 * 100
<em>%112.5</em>
<em>The increase is %12.5</em>
Answer: %12.5
Angle between 16 and 18 = 90 + 55 = 145°

Answer:
Its A)Linear
Step-by-step explanation:
So first get a graph paper and draw the Graph, then plot the points, and then see what it is. Its a linear because the line is straight.
Hope this helps
Answer:
The slope is 4 or 4/1.
Step-by-step explanation:
Since these are all in numbers evenly divisible by 10, we can go ahead and make this easier by dividing everything by 10. When we do this, we can see a point crossing an intersection at (3,1), or if you left it, (30, 10). Next, we can see another point crossing another intersection at (4,5) or (40, 50). Since we have two points that are easy for us to subtract, we can use the slope formula. The formula is as follows: y2-y1 / x2-x1. We can pick which of these we want to be 1 or 2, but whichever one we pick has to be 1 or two on both the top on the bottom. for example, I did (50-10) / (40-30). That gets us 40/10. If you divided by ten in the first place, you would get 4/1. From there, if you have the bigger answer, you need to simplify to simply 4. The shorter answer doesn't need to be simplified because we already simplified. I hope this helps!
