a scientist found a fossilized bison. using Carbon-14 dating, she found that the fossil was about 45,840 years old. Carbon-14 has a half-life of 5730 years. how many half-lives have passed?
45840/5730= 8
I DON'T KNOW THE ANSWER
To determine the number of half-lives that have passed, we need to divide the age of the fossil by its half-life.
In this case, the age of the fossil is given as 45,840 years, and the half-life of Carbon-14 is 5730 years.
To find the number of half-lives, we can divide the age of the fossil by the half-life:
Number of half-lives = Age of the fossil / Half-life
Number of half-lives = 45,840 years / 5730 years
Calculating this division, we find:
Number of half-lives ≈ 8
Therefore, approximately 8 half-lives have passed since the fossil was formed.
