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:
1376 dogs
Step-by-step explanation:
This is just a multiplication problem if we convert the words to mathematical formulas.
There are 86 teams:
. Each team has 16 dogs:
.
So, we can add up 16 to itself 86 times, which is just 16 * 86 = 1376
Thus, the answer is 1376 dogs.
Hope this helps!
