Number of students in each bus: 387÷9=43
Answer: I think the answer is 34.. sorry if I’m wrong
Step-by-step explanation:
None of the answers are correct. The correct answer would be x=(P-25)/2
I think the logical question for this would be to find the reaction rate constant, k, for radioactive decay of Rhodium. The general formula is:
ln A/A₀ = -kt,
where
A is the amount of substance after time t,
A₀ is the original amount of substance
t is the time
After 30 s, the amount of Rhodium would be in half. So, A/A₀ = 1/2
ln(1/2) = -k(30 s)
k = 0.023 s⁻¹
