Answer:
64/80
Step-by-step explanation:
When you put in your calculator 4/5 it spits out ".8".
You are looking for another fraction that spits out 0.8.
One of the choices that gets my attention is 64. Let's test it to see if I was right first try.
Calculator: 64/80 = 0.8; 64/80 is equivalent to 4/5.
At death means x= 0, so on the graph you can see that (0, 500), so 500 carbon atoms are present at death.
Plug 11,240 in for t in the equation, and you are left with N(t) = 500(1/2)^2 = 125 carbon atoms.
See the graph point (25,000, 24.298)? That means that after 25,000 years 24.298 carbon atoms will be present. So the answer is 25,000 years.
No, it's not.
15/28 equals to (about) 0.54 while 25/45 is (about) 0.56.
They are close, but not equivalent.<span />
