Answer:
The perimeter is 22.
Step-by-step explanation:
If you turn this shape into a rectangle, the perimeter doesn't change.
The width is given, it is 7.5. The height is BC+DE = 3.5
Then the perimeter is twice the width plus twice the height:
7.5*2 + 3.5*2 = 15+7 = 22
-2×-y=3-9×-y=17
=2×+9×=1y+1y=17+3
11×=2y=20
11=y=20÷2
11y=10
y=10/11
10%-8%=2
2/8=0.25
0.25×100=25
The net percentage is 25%
about 10 without a remainder of 4
So, add up the number and divide by how many number you have (definition of mean). 8 + 25 + 9 + 10 + 11 + 1 all divide by 6 (since there are 6 numbers)
8 + 25 + 9 + 10 + 11 + 1 is 64.
64/6 is about 10 without a remainder of 4
