Answer:
402 is your correct answer
Answer:
Step-by-step explanation:
Total sum of age of 12 students = 12*18 = 216;
Total sum of age of 8 students = 8*23 = 184;
Total sum of age of 20 students = 216+184 = 400;
Mean age of all the students = total age / number of students;
= 400/20 = 20 year

Answer:
60 pages
Step-by-step explanation:
% or
pages
You can mutiply 12 by 5 to get 60 pages OR: Create an expression
(0.2)x = 12 Divide both sides by 0.2
x = 60
Answer:
A=78.23in²
Step-by-step explanation:
First we need to solve for the radius. The volume of a cylinder can be found using the formula:

Now we have the variables:
V = 1177.5 in³
h = 15
r = ?




≅24.99
≅
r≅4.99in
Now since we're looking for the area of the base, we can use the formula for the area of a circle which is:


A=78.23in²
