Answer : The substances half life in days is, 5.6 days.
Step-by-step explanation :
Half life : It is defined as the amount of time taken by a radioactive material to decay to half of its original value.
All radioactive decays follow first order kinetics.
The relation between the half-life and rate constant is:

where,
k = rate constant = 0.1235 per days
= half-life
Now put all the given values in the above formula, we get:


Thus, the substances half life in days is, 5.6 days.
Answer:
4 1/6 ft
Step-by-step explanation:
Since each of the 18 students gets an equal length of ribbon, we need to divide the 75 ft of ribbon into 18 equal parts.
75/18= 4 1/6
Each student gets 4 1/6 ft of ribbon
