Five times a number is the same as 30 more than 8 times the number. a. Find the number. b. If n is "the number," what equation could be used to solve for the number? Five times a number is the same as 30 more than 8 times the number. Find the number. If n is "t...
Radioactive Decay (Half Life) Equation Radioactive Decay Graph Lesson Summary Frequently Asked Questions How do you calculate half-life decay? To calculate half-life decay, the percentage of the initial sample must decrease by half for each half-life that occurs. If the half-life of a sa...
Now the activityRis found using the equationR=0.693Nt1/2R=0.693Nt1/2. Entering known values gives R=0.693(6.52×1013)5730y=7.89×109y−1R=0.693(6.52×1013)5730y=7.89×109y−1 or 7.89 × 109decays per year. To convert this to the unit Bq, we simply convert years to seconds. Thus...
