This is not as hard as it seems. All shapes will follow ratios when they undergo a change in overall size. The first part is finding the size of line G-A. Since we know perimiter, we can simply subtract the other sides from the total permitier. This gives us that GA is 30. Since the ratio of
=
, we can simply do 14/35 = x/30. Sp x = 30*14/35 =12
The percentage of the original sample that is left after 115 days is; 23.4733%
<h3>How to calculate the decay percentage?</h3>
Formula for radioactive decay is;
A = A₀ * (1/2)^(t/t_¹/₂)
where;
A = quantity of the substance remaining
A₀ = initial quantity of the substance
t = time elapsed
t_¹/₂ = half life of the substance
Thus;
A/A₀ = (1/2)^(115/55)
A/A₀ = 0.234733 or 23.4733%

Answer:
2x10^3
Step-by-step explanation:
(5x10^-3) is .005
(4x10^5) is 400,000
Multiply together and you get 2000
move the decimal to the right 3 times and you get 2x10^3
