The common difference is 17
Answer:
V =1236.4 ft^3
Step-by-step explanation:
The volume of a cylinder is given by
V = pi r^2 h
The radius is d/2 =15/2 = 7.5
V = 3.14 (7.5)^2 * 7
V = 1236.375
Rounding to the nearest tenth
V =1236.4 ft^3
A = 2(9*11) + 1/2(8*11) + 1/2(8 * 9)
A = 198 + 44 + 36
A = 278
Answer
B. 278 in^2
The problem says that V(x)
varies directly with its length. This is a proportionality problem. So, V(x) =
kl. If you are given a length of 25 inches and a k (proportionality constant)
of 15, you are required to find its volume V(x).
V(x) = kl
V(x) = (15) (25 inches)
<u>V(x) = 375 cubic inches</u>

Answer:
There are 25 students in the class.
Step-by-step explanation:
Since we know the percentage of students who want an ice cream party is 20%, and 5 students want an ice cream party, we know that:
, where S is the total amount of students. We can then solve for S:
Given equation
Multiply by S
Divide by 0.2
Therefore, there are 25 students in the class.
