Answer:
WX = 9
Step-by-step explanation:
WY is the entire line - this tells you that the length of the entire line is 11.
XY is a section of the line, and WX is the section you need to find the length for. Since it is given that XY is of length 2, we can find the length of WX by subtracting the length of XY from WY.
11 (WY) - 2 (XY) = 9.

Answer:
First question: 2.04%
Second question: 2.5
Third question: 339.29
Step-by-step explanation:
First, find the volume of Container A. This can be found by pir^2h. r is 6, and h is 12, so the volume is 1357.17. Next, find the volume of Container B. We will use the same equation. This gives us 1385.44 for the volume of Container B. We will subtract the volume of A from B to see the difference. The difference is 28.27. We will then take the difference and divide is by the volume of B. This is 0.02. This means that 2% of Container B will be empty. Specifically, 2.04%.
For this one we can simply divide 20 by 8. This gives us a scale factor of 2.5.
In order to find the surface area of a cylinder we will use the equation 2pirh + 2pir^2. We will plug in the values of r and h in order to give us the surface area. This gives us the answer 339.29.
Each friend gets 
cards
<em><u>Solution:</u></em>
Let the number of cards in $ 27 set be "x"
Given that Nicole has $9 to spend on cards
Amount with Nicole to spend on cards = $ 9
One set costs $27
Therefore, cost of 1 set = $ 27
Each friend gets the same number of cards
She finds friends with the same amount of money to split the cost of a set
Therefore, to get total cost of 1 set which is $ 27 , we can say
$ 9 + $ 9 + $ 9 = $ 27
So 2 friends pay each $ 9 and nicole pays $ 9
Now, Number of cards each friend gets is given by
Thus each friend gets cards
