Question

you are using a magnifying glass. use the actual length of the insect and the magnification level to determine the length of the image of the insect seen through the magnifying glass.

ladybug magnification: 10 ×

the magnified length is □ millimeters.

Explanation:

Step1: Recall the magnification formula

The formula for magnification \(M=\frac{\text{Image length}}{\text{Actual length}}\).

Step2: Rearrange the formula to find the image length

We can rewrite the formula as \(\text{Image length}=M\times\text{Actual length}\). Given that \(M = 10\) (magnification) and \(\text{Actual length}=4.5\) mm.
Substitute the values into the formula: \(\text{Image length}=10\times4.5\)

Answer:

\(45\) mm
