Answer:
I think 20 but i may of done my math wrong
Step-by-step explanation:
Answer:
65*h=c
Because if it's per hour c is dependent on the amount of hours.
Note: a radioactive decay constant is always negative.
time = [natural log(ending amount / beginning amount)] / k
time = ln (20 / 24) / -.00011
time = ln (5/6) / -.00011
time = -.018232155683 / -.00011
time =
