Arectangular bathroom mirror has a perimeter of 22 feet and an area of 24 square feet. what are the dimensions of the mirror?

feet by
feet

3*8

Step-by-step explanation:

The side lengths are integer, so we have to find the factors of 24.

They are : 1, 2, 3, 4, 6, 8, 12, 24

Then we have to find a pair of factors that multiply to get 24, and add up to get 11. They have to add up to 11 because the length plus the width should be half of the perimeter. in our case, the perimeter is 22, so the width plus the length should equal 11. The only two factors that satisfy these conditions are 3 and 8

step-by-step explanation:

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
