Arectangular magazine cover is photocopied by using a scale factor of 1/3. the length of the photocopy of the magazine cover is. a)enlarge by a factor of three b)enlarged by a factor of 1/3 c)reduced by a factor of three d)reduced by a factor of 1/3

Option D. Reduced by a factor of

Step-by-step explanation:

we know that

The scale factor is equal to divide the length of the photocopy of the magazine cover by the length of the original magazine cover

Let

z-----> the scale factor

x------> the length of the photocopy of the magazine cover

y-----> the length of the original magazine cover

so

we know that

If z > 1 ---------> is an enlargement

If z<1 ------> is a reduction

In this problem we have

------> is a reduction

substitute

------> reduced by a factor of
