Answer: 18
Step-by-step explanation:
The question is asked to know 30% of 60, we get
60 x 30% = 60 x 0.3 = 18
Answer:
C.
Step-by-step explanation:
The diameter is the line across the center of the circle
Answer:



Step-by-step explanation:
Given



Rotation: 90 degrees clockwise
Required
Determine A'B'C'
When a point
is rotated 90 degrees in the clockwise direction, the new coordinates is: 
So, we have:



Becomes



So 9 students = 25% (100%-75%=25%)
100 : 25 = 4
4 * 9 =
36 students
hmmm let's find the distance between B and C first off.

hmmm if BC is that much, then AB + AC = 7, since AB + AC + BC = 12 which is the perimeter, Check the picture below.
