An amount of radium (R) disintegrates at a rate proportional to the amount present at a given time (t). It takes 1200 years for the Radium to disintegrate to 70% of its original amount (Ro), Which of the following equations best describe this condition? O R(1200) = 0.3Ro O R(1200) = 0.7R9 O R(1200) = e0.7Ro O R(1200) = e0.3Ro
