An archaeologist in turkey discovers a spear head that contains 80% of its original amount of c-14. find the age of the spear head to the nearest year.

The age of the spear head to the nearest year is 1845 years

Step-by-step explanation:

We know that

half life time of C-14 is 5730 years

so, h=5730

we can use formula

now, we can plug value

an archaeologist in turkey discovers a spear head that contains 80% of its original amount of C-14

so,

we can plug it

now, we can solve for t

So,

The age of the spear head to the nearest year is 1845 years

0.16 or 16%

step-by-step explanation:

lets take a coin for example.

if you toss it twice, it has a 1/4 chance of landing on heads both times because 1/2 * 1/2 is 1/4.

with the cards, the chance of picking dog is 0.4. having two people pick one is like picking a card twice in a row. so 0.4 * 0.4 is 0.16, or 16%

95.03 is the answer. hope this !
