The daughter should be around twelve years old.
Shes 3 and a half as stated on wiki

At the time the rock is created, the radioactive isotope is present in that rock in a ratio of 1 to zero with regard to the stable daughter. After one half-life, which is 10,000 years, the isotope to daughter ratio is 1 to 1. After another half-life, which is another 10,000 years, the ratio is 1 to 3. The rock is 20,000 years old.To see it another way, after the first half-life is complete, half the material is the original isotope, and half is the daughter. That's a 1 to 1 ratio. After another half-life (another 10,000 years) has passed, half the original isotope that was left has become the daughter. That's one quarter more of the daughter that will be added to the quantity of the daughter existing after the first half-life. That means that one quarter of the original isotope will be left after 2 half-lives, and the rest (the other 3/4ths of the material) will be the daughter. The ratio of the original isotope to the daughter after 2 half-lives (20,000 years) is 1 to 3.
yes because shes half human
Shes is shes half from Ecuador and half from Ireland. Because Ecuador is known for being Spanish
no shes half Asian and half Jewish
Yes she does. I'm sorry but I'm the person who answered the question ' Does Tess Daly have any children?'. I answered basically these words 'Yes she does. A daughter about 2 years old. I'm sorry I can't remember her name'. That answer is half right and half wrong. She does have a daughter. Correction, she has two. And I found out there names. They are called Phoebe Elisabeth Kay and Amber Isabelle Kay. Sorry again!
Then, she is obviously in half-danger.
no. shes half latino and half mexican
a sample is brought to the laboratory and the chemist determines the percentage of the daughter isotope is 87.5%. if the half-life of the isotope is 150 million years, how old is the sample?
