The age of the radioactive artifact is approximately 19029.6 years old
<h3>Radioactivity</h3>
Radioactivity is the phenomenon of the spontaneous disintegration of unstable atomic nuclei to atomic nuclei to form more energetically stable atomic nuclei. Radioactive decay is a highly exoergic, statistically random, first-order process that occurs with a small amount of mass being converted to energy.
To solve this problem, we have to find the disintegration constant and we can use the formula of half-life of the sample to do that.
The half-life of a sample is given as;
The formula of radioactivity is given as
Substituting the values into the equation
The artifact is approximately 19029.6 years.

Could you rate this is the brainliest answer?</span>
the answer is 1/8. Because you divide how many pieces there are by that same number.
Answer:
37cm
Step-by-step explanation:
width = w
length = 2w+1
perimeter = 2(length +width)
110 =2(2w+1+w)
110 = 2(3w+1)
110 = 6w+2
108 =6w
18 = w
width = w = 18cm
length = 2w+1 =2(18)+1 =36+1 =37cm
