Answer:
Approximately 3 grams left.
Step-by-step explanation:
We will utilize the standard form of an exponential function, given by:

In the case of half-life, our rate <em>r</em> will be 1/2. This is because 1/2 or 50% will be left after <em>t </em>half-lives.
Our initial amount <em>a </em>is 185 grams.
So, by substitution, we have:

Where <em>f(t)</em> denotes the amount of grams left after <em>t</em> half-lives.
We want to find the amount left after 6 half-lives. Therefore, <em>t </em>= 6. Then using our function, we acquire:

Evaluate:

So, after six half-lives, there will be approximately 3 grams left.
You lay out the triangle formula for area which would be A=(1/2)(b)(h)
plug in for variables
375=(1/2)(23.8)(b)
solve for b
Thanks for using Brainly!

I just gave you 0.888 is it's fraction and percentage.
First, 111/125 is the simplified answer and is over the 100th and is not big enough for the 1,000's.
Second, 111/125 as a percentage is 88.8%.
Have a great day.
The answer is
4 I hope this helps
The answer is 15. Just count the spaces between A and D.
