 Question 36076This question is from textbook Algebra 2 : A paleontonlogist finds a bone that has 25% of the amount of carbon-14 found in living b tissue. How old is the bone?This question is from textbook Algebra 2 Answer by stanbon(57387)   (Show Source): You can put this solution on YOUR website!A paleontonlogist finds a bone that has 25% of the amount of carbon-14 found in living b tissue. How old is the bone? Half-life of carbon-14 is 5700 years. Let "x" be the original amount of carbon-14 in the bone. EQUATION: (1/4)x=x(1/2)^(t/5700) 1/4= (1/2)^(t/5700) (1/2)^2= (1/2)^(t/5700) 2=t/5700 t = 11400 years. Cheers, Stan H.
