For number 2 you start with parenthesis first. 4×2=8. 24-2+8. Then u add 2+8=10. 24-10=14. 14 is your answer for 2.
Answer:
3.12 kg.
Step-by-step explanation:
Mass after t years:
The mass of the elements after t years is given by the following equation:
In which M(0) is the initial mass and r is the decay rate, as a decimal.
The half life of Cs-137 is 30.2 years.
This means that:
We use this to find r.
So
If the initial mass of the sample is 100kg, how much will remain after 151 years?
This is M(151), with M(0) = 100. So
The answer is 3.12 kg.
