If you want to dilate a figure that has a side length of 20 yards, to create a dilated image with a corresponding side length of 15 yards, what scale factor should you use?
1.3/4 yards
2.5 yards
3.4/3
4.3/4
To find the scale factor, we need to divide the corresponding side length of the dilated image by the corresponding side length of the original figure.
The scale factor is given by:
Scale factor = (corresponding side length of dilated image) / (corresponding side length of original figure)
In this case, the corresponding side length of the dilated image is 15 yards, and the corresponding side length of the original figure is 20 yards.
So the scale factor is:
Scale factor = 15 yards / 20 yards = 3/4
Therefore, the correct answer is 1. 3/4 yards.
