Answer:
sorry I couldn't help but I'm not really sure about this I have done this but I actually did have to ask brainly if you choose a subject if you can go to the top right corner and hit mathematics you will automatically get to answer to it but you can't just ask it to community tab because we don't know
The answer will be $13,439.16
if the notebooks cost 3.59 and pens cost 1.49, with x representing the notebooks and y representing the number of pens and an amount of $13, the inequality would be written as 3.59x+1.49y13
Pls mark as brainliest if this helped :)
We'll say beginning amount is 100
Ending Amount = Beginning Amount / 2^n where n is the number of half-lives
100 hours mean six and 2/3 half-lives will elapse
Ending Amount = 100/2^(6.666666)
Ending Amount = 100 /

<span>
101.59
</span></span></span>Ending Amount =
<span>
<span>
<span>
0.9843488532

</span>
So if we started with 100 grams after 100 hours (or 6.6666666 half-lives) we would only have <span>
<span>
0.9843488532
</span>
grams remaining.
