D. ∆UTS ≅ ∆RST

26

step-by-step explanation:

236 cm 16 time 12 = 192

6 times 7 = 42

192+42

whaere is the picture

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
