<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
Answer:
Option b - Subtract
Step-by-step explanation:
Given : Expression
To find : Which operation should be completed first in the expression below?
Solution :
P - Parentheses
E - Exponent
D - Divide
M - Multiplication
A - Addition
S - Subtraction
In the first step we solve the bracket in the expression
So, we do subtraction i.e. 12-8=4
Therefore, option b is correct.
im sorry but did you ever get the answer?
Well, I suppose you could break up the coordinate plane
in millions of different ways.
If you take each region to be all the space that is not crossed
by an axis, then you have the four Quadrants.
