Linear. because when you decrease 10 by 3 squared which is 9 you go to one and then when you decrease one by 9 you get negative 8. :)
Answer: Let us assume that our income is $X.
In the first case:
1) We received a raise and our income increased to 135% of its previous amount.
"increased to" denotes that we will multiply our original income by the percentage given.
Therefore our income would be = $X * 1.35 = $1.35
X
In the second case:
2) We received a raise and our income increased by 135%.
"increased by" denotes that we have to add the given percentage of our income to our original income.
<em><u>Therefore our income would be $X + $X*1.35= $2.35X</u></em>
Answer: from 10 to 15
Step-by-step explanation: Toby didn’t run as much in those five minutes, compared to his other times.
Alright let's start by noting that due to it having a square bottom and top the Length is equal to the Width. They gave us the surface area, but what we need is the length/width of the square top/bottom. So let's take the surface area and make it equal to the equation for the surface area of a rectangular prism (our shape):
192cm^2 = 2(lw + lh + hw)
Let's replace all the "l's" with w's (we can do this due to the fact that the length (l) equals the width (w) (l = w))
192cm^2 = 2(w*w + wh + hw)
192cm^2 = 2(w^2 + 2wh)
We know what the height (h) is as it is given in the problem (5cm).
192cm^2 = 2(w^2 + 2*5w)
192cm^2 = 2(w^2 + 10w)
Divide 2 on both sides.
96cm^2 = w^2 + 10w
Subtract 96 on both sides.
0 = w^2 + 10w - 96
Factor it out.
0 = (w - __)(w + ___)
0 = (w - 6)(w+16)
We have two possible answers of:
w = 6
w = -16
The only answer which makes sense is the positive one, because a box in real life can't have negative length.
So,
w = 6 cm.
