Answer:
Louise is 16
Todd is 18
Step-by-step explanation:
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:
x = 10/3
Step-by-step explanation:
Solve:
- 7x + 1 = 10x - 9
- 1 = 3x - 9 Isolate x
- 10 = 3x Isolate x
- x = 10/3
x = 
-Chetan K
(A) 450 ft squared.
First, calculate the old arena's dimensions.
10 x 15 = 150.
Calculate the new arena's dimensions.
20 x 30 = 600.
Now subtract 150 from 600.
600 - 150 = 450.
Hope I helped!
