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
Answer:
15 × 2 = 30

Answer:
a=1
Step-by-step explanation:
35a-29=14-8a
35a+8a=43a
43a-29=14
14+29=43
43a=43
A=1
Answer:
Option C: Copying an angle
Step-by-step explanation:
Angle bisector is a line through an angle that will split that angle to 2 equal angles. Thus, option A is wrong as no angle is being split.
Copying an angle involves reproducing a particular angle in another construction. The image shows us that there is an attempt to reproduce the perpendicular angle of 90°. Thus, option B is correct.
Copying a line segment involves creating the exact size of line in another construction. The image doesn't depict that. Thus option C is wrong.
Perpendicular bisector is when we draw a perpendicular line through a horizontal one to divide it into 2 equal parts. This is not the case here. Thus, option D is wrong.
