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!
For this case you can use the following equation:
d = (2 2/5) h
Rewriting:
d = (2.4) h
Then, we have that the height is:
h = 22 1/4
Rewriting:
h = 22.25
Finally the diameter is:
d = (2.4) (22.25)
d = 53.4 feet
The volume of the cylinder is:
V = pi * ((d / 2) ^ 2) * (h)
V = (3.14) * ((53.4 / 2) ^ 2) * (22.25)
V = 49806.05985 feet ^ 3
Nearest hundreth:
V = 49806.06 feet ^ 3
Answer:
The volume of the cylinder is:
V = 49806.06 feet ^ 3
5/7, I don't know what that is as a decimal, but I hope it helps
