Answer:
B. 60
Step-by-step explanation:
There are a total of 200 students here, and 45% got Cs, to find how many got Cs, multiply 200 by 45%, or 0.45: 200*0.45 = 90, 90 people got Cs.
15% got Ds, multiply 200 by 15%, or 0.15 to get 30, 30 got Ds
The amount who got Cs minus the amount who got Cs is 90 - 30 = 60, 60 more students got Cs than Ds
The slope of a line can be found with any two points on the line:
slope=(y2-y1)/(x2-x1) where (x1,y1) and (x2,y2) are any two points...
slope=(25-17)/(7-3)
slope=8/4
slope=2
The equation for this line would be y=((-4/9)x)+4
A = ab ( the area of rectangle )
a b = 192
a b r² = 363
192 r² = 363
r = √363 / 192 = √121/64
r = 11/8
The similarity ratio of the two rectangles is 11/8.
