Answer:
4 cm
Step-by-step explanation:
1. If you want to find the mean you should add all fundraiser totals and divide it by number of years:

2. In order to find the median, firstly you have to order the fundraiser totals from the smallest number to the greatest number:
880, 896, 914, 925, 963.
The median is the middle number, then

3. 915.6-914=1.6 - the mean is $1.60 greater than the median.
Answer: correct choice is B.
The equation given in the question is
2s + s + 12 = 132
3s + 12 = 132
3s = 132 - 12
3s = 120
s = 120/3
= 40
From the above deduction we can see that the value of the unknown variable comes out to be exactly 40. This is possible because there is a single unknown variable and a single equation to get the value of the variable from. So the correct option among all the options given in the question is option "D".
Answer:
answer a
Step-by-step explanation:
<span>If the width is w, and the length is w+10, then the perimeter is
2w+2(w+10),
If that is the case you need
4w+20-4,or 4w+16 tiles </span>
