Answer:
Per hour decay of the isotope is 0.96%.
Step-by-step explanation:
Amount of radioactive element remaining after t hours is represented by

where a = initial amount
t = duration of decay (in hours)
Amount remaining after 1 hour will be,

y = 0.9904a
So amount of decay in one hour = a - 0.9904a
= 0.0096a gms
Percentage decay every hour = 
= 
= 0.958 %
≈ 0.96 %
Therefore, per hour decay of the radioactive isotope is 0.96%.

u tell me bro
Step-by-step explanation:
Answer: choice 1 and 6
Step-by-step explanation:
just plug in 9 for every X making sure they equal each other.
24 divided by 8 is 3.
3 times 9 is 27 so your ratio would be
24/27 = 8/9
or 24: 27= 8:9
so your answer is 27
