Which equations represent the scenario if w is the number of white shirts and t is the number of tie-dye shirts sold? Check all that apply. w + t = 500
w + t = 9000
15w + 20t = 500
15w + 20t = 9000
20w + 15t = 9000

54.864 meters

answer: im sorry i dont get it

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
