Answer:
16 girls in the class
14 boys in the class
Step-by-step explanation:
Because of the ratio of 7:8, I added 7+8.
7+8= 15
30 (the number of students in the class) divided by 15 (the sum of the ratio)
30/15= 2
I then multiplied 8 from the "girls" part of the ratio by 2 (the quotient of 30/15) and got 16. Then I subtracted 16 from 30 and got 14, which s the number of boys in the class.
Hope this helps!

Answer:
V =150.8 in ^3
Step-by-step explanation:

V = pi * (2^2) * 12
V =3.14159 * 4*12
V =150.7964474 in^3
to the nearest tenth
V =150.8 in ^3
× 100 = 7%
