Radioactive dating math problems

In the case of radiocarbon dating, the half-life of carbon 14 is 5,730 years.This half life is a relatively small number, which means that carbon 14 dating is not particularly helpful for very recent deaths and deaths more than 50,000 years ago.Try the problems out, then check your answer below. If an element has a half-life of twenty million years, and there is 6.25% of it remaining in a rock, how old is the rock? In a certain rock, there is 1/16th of the original parent element, and 15/16th of the daughter element. Both species have skin flaps that let them glide from tree to tree, although they are not closely related to each other. Australian sugar gliders are squirrel-like marsupial mammals (their young develop inside an external pouch).

If 1/8 of the parent material remains, that means that the rock is 3 half-lives old. 2 half-lives = 1/4 remaining, and 3 half-lives = 1/8 remaining. D is the only tree that shows that species A is more closely related to species D.

Why do scientists think that bipedal posture evolved in humans?

The environment of east Africa became more forested.

After 5,730 years, the amount of carbon 14 left in the body is half of the original amount.

If the amount of carbon 14 is halved every 5,730 years, it will not take very long to reach an amount that is too small to analyze.
