D. 13 to 18
Cause there are 13 pens to every 18 pencils
Hope this helped :)
Answer: The sample is 13414 years old.
Step-by-step explanation:
Expression for rate law for first order kinetics is given by:
where,
k = rate constant
t = age of sample
a = let initial amount of the reactant= 100
a - x = amount left after decay process=
a) for completion of half life:
Half life is the amount of time taken by a radioactive material to decay to half of its original value.
b) for completion of 20% of reaction
The sample is 13414 years old.

We have been given that red, green, and white jellybeans are combined in a ratio of 5:4:3 respectively. We are asked to find out the ratio of green jelly beans to the total number of jelly beans.
In order to find out the ratio of green jelly beans to the total number of jelly beans we have to find out the total number of jelly beans.
![\text{Total number of jelly beans}=5+4+3=12](https://tex.z-dn.net/?f=%5Ctext%7BTotal%20number%20of%20jelly%20beans%7D%3D5%2B4%2B3%3D12)
Now we can find out out our desirable ratio by substituting our finding in the ratio.
![\text{Number of green jelly beans}:\text{Total number of jelly beans}=4:12\\=1:3](https://tex.z-dn.net/?f=%5Ctext%7BNumber%20of%20green%20jelly%20beans%7D%3A%5Ctext%7BTotal%20number%20of%20jelly%20beans%7D%3D4%3A12%5C%5C%3D1%3A3)
Therefore, ratio of green jelly beans with respect to all jelly beans is 1:3.
