A microscope shows you an image of an object that is 20 times the object's actual size. So the scale factor of the enlargement is 20.
An insect has a body length of 15 millimeters. What is the body length of the insect under the microscope?
20 millimeters
200 millimeters
3,000 millimeters
300 millimeters
300 millimeters
To find the body length of the insect under the microscope, you would multiply the actual body length by the scale factor of 20.
15 mm x 20 = 300 mm
Therefore, the body length of the insect under the microscope is 300 millimeters.
