A real 3cm bug is drawn to be 10 cm in a picture. What scale factor was used?
To determine the scale factor, we can divide the size in the picture by the actual size.
Scale factor = Size in the picture / Actual size
Given that the bug measures 10 cm in the picture and its actual size is 3 cm,
Scale factor = 10 cm / 3 cm = 3.33 (rounded to two decimal places)
Therefore, the scale factor used is approximately 3.33.
