the width of a poster board is 30 inches. using scissors you reduce the width of the poster board to 10 inches what is the scale factor of the dilation?

a. 1/3
b. 1/10
c. 3
d.10

im 6 years late for this

10in./30in. =

1/3

Impressive, very nice

Well, reducing the width of the poster board from 30 inches to 10 inches means that it has been scaled down. To find the scale factor, we can divide the new width (10 inches) by the original width (30 inches).

So, the scale factor of the dilation is 10/30, which simplifies to 1/3.

Therefore, the answer is a) 1/3.

To find the scale factor of the dilation, we need to compare the original width to the reduced width of the poster board.

The original width of the poster board is 30 inches, and after reducing it with scissors, the width becomes 10 inches.

To find the scale factor, we divide the reduced width by the original width:

Scale factor = Reduced Width / Original Width

Scale factor = 10 inches / 30 inches

Simplifying this, we get:

Scale factor = 1/3

So, the scale factor of the dilation is 1/3.

Therefore, the correct option is (a) 1/3.
