Since you can 4 pieces from 1 foot, you multiply 4 by 5 and you get 20 pieces.
Answer:
- A'(0,1), B'(1,0) and the lines are parallel
- dilation factor is 2
- A(-2,0), B(2,0); twice the length
Step-by-step explanation:
1. Whenever dilation is about the origin, the dilation factor affects each coordinate individually. When the dilation factor is 1/2, each coordinate of the image is 1/2 the coordinate of the pre-image:
A(0, 2) ⇒ A'(0, 1)
B(2, 0) ⇒ B'(1, 0)

2. The above description works in reverse, as well. If the dilation factor is 1/2, the pre-image has coordinate values twice those of the image. Dilation does not change directions or angles, so any dilated lines are parallel.
__
3. The center of dilation is an invariant point: it does not move. As in the second problem, the pre-image is twice the size of the image when the scale factor is 1/2.
Answer:
c
Step-by-step explanation:
The volume (V) of a square based pyramid is calculated as
V = 
Ah ( A is the area of the base and h is the height )
Here V = 1350, thus
× 15²h = 1350 ( multiply both sides by 3 to clear the fraction )
225h = 4050 ( divide both sides by 225 )
h = 18 ft → c
62.5/100 is what i think the answer is i might be wrong
Answer:
57.6 miles per hour
Step-by-step explanation:
0.96 miles per minute
60 minutes per hour
0.96X60=57.6 miles per hour
