The two figures are congruent because the side lengths are the same, therefore making the angle measures the same.
Answer:
A
Step-by-step explanation:
The volume of a cone has the formula:

Where
V is the volume
r is the radius
h is the height
Given,
h = 50
V = 5400π
We want the radius, r.
Lets substitute and solve for r:

The radius is 18 meters
Correct answer A
1/2x(25-7). Difference means to subtract. And then just multiply by 1/2 since it is asking for half.
Just isolate the y in both cases:
4y=-3+2x, y=-3/4+1/2x
-2y=-3x+4, y=3/2x-2
Answer:
36.19047619 million
or 36,190,476 students
Step-by-step explanation:
7.6 million / all students = 21% / 100%
7.6 * 100 / 21 = 36.19047619
36.19047619 million
or 36,190,476 students
