Question

phytoplankton is 3 μm long. under a microscope, it looks 46,500 μm long. what magnification scale was used? hint: scale factor = scaled image dimension / original dimension

Explanation:

Step1: Identify values

Scaled image dimension = 46500 μm, Original dimension = 3 μm

Step2: Apply scale - factor formula

Scale factor = $\frac{Scaled\ Image\ Dimension}{Original\ Dimension}=\frac{46500}{3}$

Step3: Calculate the result

$\frac{46500}{3}=15500$

Answer:

15,500
