Astudent sees a newspaper ad for an apartment that has 1345 square feet (ft2) of floor space. how many square meters of area are there? area of apartment

For this case we have the following conversion of units:

Therefore, we must apply this conversion for the apartment area.

We have then:

The area of the apartment in square meters is given by:

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
