This is a typical radioactive decay problem which uses the general form:
A = A0e^(-kt)
So, in the given equation, A0 = 192 and k = 0.015. We are to find the amount of substance left after t = 55 years. That would be represented by A. The solution is as follows:
A = 192e^(-0.015*55)
<em>A = 84 mg</em>
Answer:
It's 6/7
Step-by-step explanation:
Answer:
125
Step-by-step explanation:
First, solve the exponent:
5^2 = 5x5 = 25
Then solve the rest:
5x25-125
For the answer to the question above, the answer is 16.
You would divide 12 by 3 since that's the number of red dots per blue. Then multiply by four and there's the answer!
I hope my answer helped you. Feel free to ask more questions. Have a nice day!
