48 students are girls they make up 60% of the class how many students total
qwelly [4]
For this you would do
48 \div .60
Because 60% is the same as 0.60. And solving a problem like this is the opposite of finding a percent of a number. When you solve this you get 80. So there are 80 students in total.

Organize your data and find the rate of change.
LuckyWell [14K]
A .E is 7 inches for the left arm
E is 8 1/2 inches for the left foot
the inputs look like the length of the arm (ie x) the outputs are the length of the foot 
<span>rate of change=<span>change in y change in x</span></span> use the data you gathered or this equation they give you  = 0.860 •  + 3.302


B. find the difference in y, then the difference in x, then divide (y over x) to get the slope
8-7/7 1/2-6 1/2 = 1/1 =1

C.you plug in any (x,y) point you used to find the slope
Solve for B
y = mx+b y = 1*x + b 7.5 = 1*8 + b b =
7.5 - 8 = -0.5
<span>y = x - 0.5</span>

Hope this helps
