How would I plot this?
____ [38]

Answer:

Step-by-step explanation:

As the center of dilation is A, it does not change.

As A is the origin, B is (12, 4)

So B' will be (12/4, 4/4) = (3, 1)

Or from A move 3 right and 1 up

As A is the origin, C is (8, - 8)

So C' will be (8/4, -8/4) = (2, -2)

Or from A move 2 right and 2 down.

Zoey can tile 1 1/4 square yards in 1/3 hour. What is her unit rate?
alukav5142 [94]
We know that Zoey can tile 1.25 square yards in 20 minutes (which is 1/3 of an hour) so we wanna see how much she can tile in an hour. Multiply 1.25 by 3.

1.25•3= 3.75 or 3 3/4
