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:

Answer:
62.8 inches
Step-by-step explanation:
✓We can determine the
Circumference of the wheel of the bicycle using the expression below;
Circumference= (πd) ...........eqn(1)
Where d= diameter = 20inches
If we substitute the value of " diameter" into eqn(1)
Circumference = (π × 20)
= 62.8inches
(Where π= 3.142)
Therefore, measurement that is closest to the circumference of the wheel is 62.8inches
