<span>Formula for exponential decay is:
N = No * e^-kt
N = 1/2(45) = 22.5
No = 45
k = 0.1109
The solution to your problem is as follows:
Let's try to solve the half-life if it is 45 grams, after which, you will now have an idea on how to solve the problem.
22.5 = 45 * e^(-0.1109t)
1/2 = e^(-0.1109t)
ln(1/2) = -0.1109t
t = (ln(1/2))/(-0.1109) = 6.25 days

Answer:
It's 975 because they traveled for 17 hours and had stopped for 2 hours do 17-2=15, so 15×65=975
Step-by-step explanation:
Answer:
17.7
Step-by-step explanation:
<em>First off, we do not need to do anything to the 17, it is already set up for a decimal. So we have to find out how much 1/50 is so we divide:</em>
<u>Divide:</u>
1/50=0.02
<u>Multiply by 35:</u>
0.02 times 35= 0.7
<u>Add the 17:</u>
17+0.7=<em><u>17.7</u></em>
I hope this helps u pls give a brainliest and a thx ;)
leave a comment if i am wrong
Answer is 12.50. u can comment on my answer if you would like to see how that is the correct answer :)
