What is the length of the midsegment of this trapezoid? Enter your answer in the box.

7 units

Step-by-step explanation:

the midsegment is equal to the half of the sum of both bases. they're equal to 6 and 8 units so the midsegmet is equal to (6+8)/2=7units

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
