About 92 days are taken for 90 % of the material to <em>decay</em>.
The mass of radioisotopes (
), measured in milligrams, decreases exponentially in time (
), measured in days. The model that represents such decrease is described below:
(1)
Where:
- Initial mass, in milligrams.
- Current mass, in milligrams.
- Time constant, in days.
In addition, the time constant is defined in terms of half-life (
), in days:
(2)
If we know that 
, 
and 
, then the time required for decaying is:
About 92 days are taken for 90 % of the material to <em>decay</em>.

Answer:
224 with a remainder of 9
Answer:
72
Step-by-step explanation:
Stage A has 6 outcomes, then B has 4 and C has 3
Take for example only 1 outcome of A, it will have 4 outcomes of B and each outcome of B will have 3 outcomes.
Then a single outcome of A has a total of 12 outcomes (4*3)
Writing it in a way A, B, C:
1,1,1
1,1,2
1,1,3
1,2,1
1,2,2
1,2,3
1,3,1
1,3,2
1,3,3
1,4,1
1,4,2
1,4,3
This is only taking in consideration 1 outcome of A, A has a total of 6 outcomes.
The total of outcomes in the experiment = 6*12=72
