Step-by-step explanation:
the radius is diameter divided by 2
7/2/2 =1 .75
circumference of a circle is 2πr
2*22/7*1.75=11
3.14*11 =34.54
Answer:
21%
Step-by-step explanation:
Out of the 25 + 9 + 12 + 21 + 12 + 21 = 100 total rolls, 6 came up 21 times so the percentage is 21/100 = 21%.
I hope this helps.

In order to express this in the distributive property, they have to have something in common, (also called the GCF or Greatest Common Factor). So, the greatest common factor of 35 and 7 is in fact 7. So you would divide both of these numbers by 7, and then put them in parentheses with a seven as the division on the outside.
Your final product should look like this 7(5+1).
Hi!
First, let's find the LCD of the denominators. (5, 4, and 2)
2, 4, 6, 8, 10, 12, 14, 16, 18, 20
4, 8, 12, 16, 20
5, 10, 15, 20
Now we have to change all of the numerators to match the denominators.
Since 5 goes into 20 four times..
2 x 4 = 8
8/20
Since 4 goes into 20 five times...
3 x 5 = 15
15/20
Since 2 goes into 20 ten times...
1 x 10 = 10
10/20
Our new fractions are..
8/20+15/20+10/20=?
Now just add the numerators.
33/20
If you want to simplify it to a mixed number, your answer is 1 13/20
If you want to keep it as a fraction, it's already in simplest form. So the answer is 33/20
Hope this helps! :)
Answer:
b = 18 + a
Step-by-step explanation:
because b is the total number of employees during the holidays
so 18 is what they already have/have all the time plus the number of employees who are temporary during the holidays
