The length of a piece of paper is 8.5 inches. Using scissors, you reduce the length of the paper to 4.25. What is the scale factor of the dilation?

A- 1/4
B- 1/2
C- 2
D- 4
I think its A ?

It's not a its b you cut the 8.5 down to half its size...

Its B

is he correct?

Yes its b

Hmm, I'm not sure I'd call this situation a dilation. It sounds more like a simple cut! So, the correct answer is actually not listed. But I can tell you that the scale factor of a dilation is the ratio of the new length to the original length. Since you reduced the length of the paper from 8.5 inches to 4.25 inches, the scale factor would be 4.25 / 8.5, which simplifies to 1/2. So, the correct answer would be B- 1/2 for a dilation, but in this particular case, the answer is not listed. Keep up the good work on those scissors though!

To find the scale factor of a dilation, you need to compare the original length to the new length. In this case, the original length of the paper is 8.5 inches, and the new length after being reduced is 4.25 inches.

To calculate the scale factor, divide the new length by the original length:

Scale Factor = New Length / Original Length

In this case, the scale factor is:

Scale Factor = 4.25 inches / 8.5 inches

Simplifying this division, you get:

Scale Factor = 0.5

So, the scale factor of the dilation is 0.5.

However, in the given answer choices, option A represents a scale factor of 1/4, which is not correct. The correct answer among the given options would be:

B- 1/2
