Answer:
72
Step-by-step explanation:
You can find ten percent of 180 pretty easily, it is 18 (divide by 10) then multiply by 4 to get 40%.
Answer:
140 feet
Step-by-step explanation:
You will need to find the perimeter of the backyard to find how many feet of fencing will be needed
the formula for perimeter is: 2l+2w
So 2 times 30 is 60
with 2 times 40 80
60+80 is 140
Thus you will need 140 feet to cover the backyard
Hope this helps!

Answer:
75 degrees
Step-by-step explanation:
both the angles must add up to 18.
180 - 105 = 75
105 + 75 = 180
If rectangle ABCD, defined by the coordinates A(0, 0), B(0, -4), C(-2, -4), D(-2, 0), is dilated by a scale factor of 2, with re
notsponge [240]
Answer:
D) (-2, -4).
Step-by-step explanation:
Let
be the center of dilation. Imagine that
is the center of origin of a new Cartesian Plane. What would the coordinates of point A and A' on the new plane?
Dilating
about the "origin" of the new plane by a factor of two will give the point
, also on the new plane.
For coordinates of A' on the original plane,
.
As a result,
.
.
.
In other words,
is the center of dilation.
