Question

The zoom feature on a camera lens allows you to dilate what appears on the display. When you change from 100% to 600%, the new image on your screen in an enlargement of the original image with a scale factor of 5. If the new image is 36 millimeters wide, what was the width of the original image?

A: 6 mm
B: 2mm
C: 12 mm
D:5 mm

Answer 1

Answer:6mm

Explanation:

So we know that you started with 100% and ended with 600% to get from 100 to 600 you would need to multiply by 6

100 * 6 = 600

So you know that to get back to your original number you would need to divide by 6

If you are trying to figure out what the original width is you would divide your current number by 6 to get the original number

36 / 6 = 6
