In mathematics, the term "center of dilation" refers to a constant point on a surface from which all other points are either enlarged or compressed. The center of dilation and the scale factor comprise the two properties of a dilation.
Add the amount of choices, and divide by the number of customers surveyed.
40 + 32 + 8 + 20 = 100
40 customers were surveyed
100/40 = 2.5
The average number should be D) 2.5

1. The problem gives the following information: <span>Ashley said she drank 1/2 pints and Claire said she drank 0.7 pints.
2. Therefore, to solve this problem you must follow the proccedure that is shown below:
3. You must sum the amount of water that Ashley and Claire drank before the practice. Then, you have:
1/2 pints=0.5 pints (Ashley)
0.7 pints (Claire)
x=0.5 pints+0.7 pints
x=1.2 pints
</span><span>

Answer:
3/5
Step-by-step explanation:
The given ratio is ...
water : juice = 3 : 5
Divide both numbers by 5 to see how much water is needed with 1 cup of juice.
water : juice = (3/5) : 1
3/5 parts of water are mixed with 1 part of juice.
