The initial number of carbon-14 atoms in the organism
at death is
After 11,460 years, there will be carbon-14
atoms in the organism.
After
years, there will be 24.298 carbon-14
atoms in the organism.

The death is 500, there will be 125 carbon-14 atoms, and after 25,000 years.

Step-by-step explanation:

I just took a test and got it right, I can't do math (;

step-by-step explanation:

δabc ≅ δdcb by sas because

db ≅ ac . . given (side)

bc ≅ bc . . reflexive property (side)

∠dbc ≅ ∠ acb . . alternate interior angles where transversal bc crosses parallel lines bd and ac (included angle)
