Answer:
Step-by-step explanation:
If we're asked to use any positive value. It means we could have a wide variety of answer. A positive value of k that makes the equation 20k to be less than 20, yet greater than zero has to be any decimal value or a fraction, if you so wish.
As an example, if k is 0.5. Then we have
20k = 20 * 0.5 = 10, which is less than 20 and greater than zero
Again, if k is 0.9. Then we have
20k = 20 * 0.9 = 18, which is less than 20 and greater than zero.
So, you use any decimal number greater than 0, yet less than 1

The percentage of the radioactive isotope left is 25.0000%.
<h3>What is the half life?</h3>
The half life of a radioactive isotope is the time that will elapse before only half of the number of original isotopes will remain.
Now;
We are told that;
Half life (t1/2) = 55 days
Time taken (t) = 115 days
Ratio of isotope remaining = N/No
Thus;
N/No = (1/2)^t/t1/2
N/No = (1/2)^115/55
N/No = (1/2)^2
N/No =1/4
Hence, the percentage = 1/4 * 100/1 = 25.0000%
