Answer:
B
Step-by-step explanation:
A is missing a combination AR and has repeats such as AG and GA. Since the order of the sides doesn't matter, AG and GA are the same thing.
C is missing many combinations, it only has 4
D has two of the same sides. The question states "you can choose two <em>different </em>sides" so something like AA is not an option
We can use the process of elimination to conclude the answer is B.
Katie has read 32%, so 32%=80 pages. To get the total number of pages, you have to divide 32 and 80 by 8 to get 4% and 10 pages. 4% of the book is 10 pages, and in order to get 100%, you have to multiply by 25(4*25=100) on both sides. Remember, what you do to one side, you do to the other side. That leaves you with 100% and 250 pages. The book is 250 pages long. If she has read 80 pages, you subtract 80 from 250 to find how many pages she has left to read. The difference is 170. Katie has 170 pages left to read.
Answer:
1296π m^3
Step-by-step explanation:
The volume of a cylinder is given by
V=πr^2h
We are given the diameter. To find the radius, divide the diameter in half.
r = d/2 = 24/2 = 12
Substituting in what we know
V = pi * (12)^2 * 9
V = pi *1296 m^3
3.20 for 8 ounces would be 25.60 or 25.6
