B) 231
To get the answer, you first need to figure out how many men are in the book club:
- Multiply the total number of members (315) by the fraction of members that are men (4/15)
- (4/15) * 315
- Multiply 4 by 315, and then divide by 15.
- This will give you the number of men (84)
Then you need to figure out how many women there are:
- Subtract the number of men (84) from the total number of members (315)
- 315 total members - 84 male members = 231 female members
Solution: Let "m" be the number of marbles Santana has.
First he wants to give one-tenth of his marbles to his brother. That is:
He also wants to give 8 more marbles to his brother.
Therefore,
Santana wants to give 
marbles to his brother
Answer: 1 cup of sugar
Step-by-step explanation:
A recipe for banana bread requires 3 cups of bananas for every 1 1/2 cups of sugar used.
Converting 1 1/2 cups of sugar to improper fraction becomes 3/2 cups of sugar.
If 3 cups of bananas is required for 3/2 cups of sugar,
x cups of bananas will require 1 cup of sugar
3x / 2 = 3
3x = 6
x = 6/3 = 2
Therefore,
2 cups of bananas will require 1 cup of sugar.
We are looking for the number of cups of sugar that would require 2 cups of bananas.
We already got the answer.
1 cup of sugar would be used if 2 cups of bananas are used.
Answer:
total surface area Stot = 753.9816 m2
lateral surface area Slat = 351.85808 m2
top surface area Stop = 201.06176 m2
bottom surface area Sbot = 201.06176 m2
Answer:
Max vol = 2 cubic metres
Step-by-step explanation:
Given that from a square piece of cardboard paper of area size 9 m2 , squares of the same size are cut off from each corner of the paper.
Side of the square = 3m
If squares are to be cut from the corners of the cardboard we have the dimensions of the box as
3-2x, 3-2x and x.
Hence x can never be greater than or equal to 1.5
V(x) = Volume = 
We use derivative test to find the maxima
Equate I derivative to 0
If x= 3/2 box will have 0 volume
So this is ignored
V"(1/2) <0
So maximum when x =1/2
Maximum volume
=
cubic metres
