Dakota drew a scale drawing of a summer camp. The sand volleyball court, which is 8 meters wide in real life, is 4 millimeters wide in the drawing. What is the scale of the drawing?

1 millimeter = 2 meters

Step-by-step explanation:

Scales are used in drawings to represent large buildings and places.

Given

Original width of basketball court = w = 8 meters

Width in drawing = s = 4 millimeters

In order to find the scale we have to divide the original width by the width in drawing.

This means that 1 millimeter represents 2 meters of the original court

1 millimeter = 2 meters

ending amount = beginning amount / (2^n)

where "n" = number of half-lives (or elapsed time / half-life)

ending amount = 50 mg / (2 ^10 / 5.3)

ending amount = 50 mg / (2 ^ 1.8867924528)

ending amount = 50 m / 3.6981210597

ending amount = 13.5203794557 mg

or about 13.5 mg remain
