Answer:
The rock is 3.75 billion years ago.
Explanation:
Given that:
Half life = 1.25 billion years
1 billion years = 10⁹ years
So,
Half life = 1.25 × 10⁹ years

Where, k is rate constant
So,


The rate constant, k = 5.5452 × 10⁻¹⁰ years⁻¹
Initial amount [A₀] = 80 micrograms
Final amount
= 10 micrograms
Using integrated rate law for first order kinetics as:
![[A_t]=[A_0]e^{-kt}](https://tex.z-dn.net/?f=%5BA_t%5D%3D%5BA_0%5De%5E%7B-kt%7D)
So,





So,
<u>The rock is 3.75 billion years ago.</u>
According to <span>The Gospel of Wealth, every person has to get paid the same amount of money, whereas the idea of social Darwinism is that only the strongest will survive, so, I bet the way how </span><span>the gospel of wealth justifies social darwinism is that if everyone will get paid the same amount of money, the strong person won't be able to win as everyone would be alike (reminds of basic ideas of socialism).

Answer:
The left side of the equation will result in a rational number, which could be a non-perfect square.
Explanation:
According to the Pythagorean theorem, the sum of the squares of the legs of a right triangle is equal to the square of the hypotenuse.
Take 

As
,
Here, 29 is not a perfect square.
So, c is irrational.
If a is a rational number and b is a rational number, c could be an irrational number as the left side of the equation will result in a rational number, which could be a non-perfect square.
Answer:
Hi. When searching for your question on the internet, I was able to find another question exactly the same as yours that had answer options, which you didn't show in this question. These answer options are in the attached image below and the correct answer is option B.
Explanation:
As shown in the question, the Andersen and Bem experiment was a replication of the getting-acquainted telephone study by Snyder, Elizabeth Tanke, and Berscheid, the difference being that the Andersen and Bem experiment used photos of men and female volunteers, while the other experiment featured photos of women and male volunteers. In the two experiments, the results were similar.
In these results, the researchers noticed that volunteers tended to think they were talking to people they found attractive when looking at the photos. In this case, volunteers were more open and more likely to keep in touch with those they thought were attractive people.
Answer:
avoid the routes that include a McDonald's and instead drive by Wendy's
Explanation:
Based on the information provided within the question it can be said that one way of doing this would be to avoid the routes that include a McDonald's. Instead drive by an alternative SD such as Wendy's and when passing near the Wendy's ask the student if they would like to eat at Wendy's. This would recondition the child's inappropriate chain of behaviors and substitute a new one with Wendy's.
