The ratio is 4:5 meaning out of 9 students 4 are girls and 5 are boys. If there are 36 students, 9 will go into 36 four times so if we multiply each number of the ratio by 4 it gives us the answer.
4:5
4x4 = 16
5x4 = 20
The ratio is 16:20
16 girls to 20 boys... 16 +20 = 36
1 radian = 57.3 degrees
60 <span>÷ 57.3 = 1.047

correct answer: C
V = volume of cone
r = radius
h = height
Formula:
V = pi*r^2*h
Plug in r = 1.5 (since d = 3 is the diameter, you cut it in half to get the radius) and h = 6
V = pi*r^2*h
V = pi*1.5^2*6
V = 13.5*pi
V = 13.5*3.14
V = 42.39
Answer: 42.39
Answer:
n = 20
Step-by-step explanation:
n/2 - 9 = 1
Add 9 to each side
n/2 -9+9 = 1+9
n/2 = 10
Multiply by 2 on each side
n/2*2 = 10*2
n = 20
