Answer:
21.46 cm²
Step-by-step explanation:
So we need to find the r for the circle
r=10/4=5/2
so the area of one circle is Ac=πr²
Ac=π(5/2)²=25/4π
and there are 4 of them: 25/4π*4=25π=78.54
the area of square is 10²=100
100-78.54=21.46 cm²

1.125 yards of fabric. To do this you need to divide .75 or 3/4 by 2 because .75 is 2/3 what you had. multiply .75/2 which is .375 and multiply it by 3 which then becomes 1.125 yards which is your answer. Don't forget the label!!! :)
Answer:
FG = 47
Step-by-step explanation:
The opposite sides of a parallelogram are parallel and congruent, thus
EH = FG, that is
5z - 18 = 3z + 8 ( subtract 3z from both sides )
2z - 18 = 8 ( add 18 to both sides )
2z = 26 ( divide both sides by 2 )
z = 13
Hence
FG = 3z + 8 = (3 × 13) + 8 = 39 + 8 = 47
Answer:
Associative
Step-by-step explanation:
The associative property of addition states that you can add numbers however they are grouped inside parentheses.
It doesn't matter where you put the parentheses. You will always get the same answer.
For example,
![\begin{array}{rcl}(5 + 3) + 7 & = & 5 + (3 + 7)\\8 + 7& = & 5 + 10\\15 & = & 15\\\end{array}](https://tex.z-dn.net/?f=%5Cbegin%7Barray%7D%7Brcl%7D%285%20%2B%203%29%20%2B%207%20%26%20%3D%20%26%205%20%2B%20%283%20%2B%207%29%5C%5C8%20%2B%207%26%20%3D%20%26%205%20%2B%2010%5C%5C15%20%26%20%3D%20%26%2015%5C%5C%5Cend%7Barray%7D)
