A sample of a radioactive isotope had an initial mass of 730 mg in 2000 and decays exponentially over time. A measurement in the year 2002
found that the sample's mass had decayed to 510 mg. What would be the
expected mass of the sample in the year 2011, to the nearest whole number?

x+y = 29, 5x + 2y = 100

step-by-step explanation:

i'm guessing it was a multiple first option was the correct answer

part 1 answer = 8

part 2 answer = 72

step-by-step explanation:

part 1 explanation = add all of the numbers, then divide by how many numbers you have. so, 200/25 = 8.

part 2 explanation = not gonna lie, this is hard to explain, so just google how to do it.

10000

step-by-step explanation: divide by 2,
