In the given question, there are several information's of immense importance. using these information's the correct and the required answer can be determined. It is given that an unknown number has to be found from the information's provided.
Let us assume the unknown number = x
Then
3x + 3 = 2x -1
3x - 2x = -1 -3
x = -4
So the unknown number is -4.
It should be remembered that these are trick questions and it is important to go through each lines very carefully to understand the inner meaning.
Answer:
Step-by-step explanation:
We have been given that Radium-226, a common isotope of radium, has a half-life of 1,620 years.
We will use half life formula to solve our given problem.
, where,
,
,
.
As we are told that the sample has 120 grams, this means that a equals 120. Upon substituting our given values in half life formula we will get,
Therefore, the equation represents the remaining amount of Radium-226 after t years.
