<h2>
Half Life</h2>
The half life period is the time in which only half of the given population remains. It can be represented through this equation:
- <em>t</em> = time passed
- <em>a</em> = y-intercept
- <em>h</em> = half life
<h2>Solving the Question</h2>
We're given:
- <em>h</em> = 28 million years
- <em>a</em> = 184 grams (this is the initial mass, after 0 time has passed)
For most questions like this, we would have to plug these values into the equation mentioned above. However, this question asks for the time elapsed after 3 half-lives.
This can be calculated simply by multiplying the given half-life by 3:
28 million years x 3
= 84 million years
<h2>Answer</h2>
84 million years
We will recommend option C which is Salaried pay. Salaried employees make more per week than hourly employees.
<h3>How do you find out the best salary option?</h3>
Given that, Salary per year = $78,000.
Hourly employees get paid $26 per hour, but get $39 per hour for each hour over 40 hours.
The total number of working hours from Sunday to Saturday is 47.
The payment for 47 hours of work per week will be given below.
Salary per week = 
Salary per week = $1313
We know that there are 52 weeks in one year. So the salary for one year is given below.
Salary per year = 
Salary per year = $68276
We can see that we calculate the yearly salary with per hour rate, the amount will be lower than the salary per year $78000.
Hence we will recommend option C which is Salaried pay. Salaried employees make more per week than hourly employees.

Answer:
See explanation
Step-by-step explanation:
Solution:-
- We will use the basic formulas for calculating the volumes of two solid bodies.
- The volume of a cylinder ( V_l ) is represented by:
- Similarly, the volume of cone ( V_c ) is represented by:
Where,
r : The radius of cylinder / radius of circular base of the cone
h : The height of the cylinder / cone
- We will investigate the correlation between the volume of each of the two bodies wit the radius ( r ). We will assume that the height of cylinder/cone as a constant.
- We will represent a proportionality of Volume ( V ) with respect to ( r ):
Where,
C: The constant of proportionality
- Hence the proportional relation is expressed as:
V∝ r^2
- The volume ( V ) is proportional to the square of the radius. Now we will see the effect of multiplying the radius ( r ) with a positive number ( a ) on the volume of either of the two bodies:
- Hence, we see a general rule frm above relation that multiplying the result by square of the multiple ( a^2 ) will give us the equivalent result as multiplying a multiple ( a ) with radius ( r ).
- Hence, the relations for each of the two bodies becomes:
