Answer:
7.74 square cm
Step-by-step explanation:
To find the leftovers, calculate the area of the square and the area of the circle. Then subtract the two.
Square: A = s*s = 6*6 = 36
Circle: 
The area leftover is A = 36 - 28.26 = 7.74
Answer:
12
Step-by-step explanation:
0 + 12 = 12
If there were 5 yes votes for every 4 no votes, there were 5 yes votes for every 9 total votes, so 5/9 of the 7911 votes were yes. 5/9*7911=4395.
To find which ratio is higher, we can first convert the ratios into fractions (that makes it easier, at least for me) and then simplify the fractions and see which one is greater.
Since ratios are basically division, 15:20 =
, and
12:16 = 
Now we simplify these fractions. 15 and 20 have a GCF of 5, so taking out the common number gives us the simplified fraction of
.
12 and 16 have a GCF of 4, so taking out the common number gives us the simplified fraction of
. Since
=
, these ratios are the same.
Solution
Part 3
For this case we have 6 different terms
Part 4
We can do the following:

Part 5
And we can simplify on this way:
