the width of a picture is 20 cm. using a color copier, you reduce the width of the picture to 5 cm. what is the scale factor of the dilation?
pls help
1/4
To find the scale factor of the dilation, divide the new width of the picture by the original width:
Scale factor = New width / Original width = 5 cm / 20 cm
Simplifying the fraction, we get:
Scale factor = 1/4
Therefore, the scale factor of the dilation is 1/4.
To find the scale factor of the dilation, you need to divide the new width by the original width.
In this case, the new width is 5 cm and the original width is 20 cm.
So, to find the scale factor, divide the new width (5 cm) by the original width (20 cm):
Scale factor = new width / original width
Scale factor = 5 cm / 20 cm
Now, simplify the fraction:
Scale factor = 1/4
Therefore, the scale factor of the dilation is 1/4.
