Answer:
I don't know what to pick! both look sooooo yummy =P. If i had to chosse i would pick the second one.
Step-by-step explanation:
<span>So we need to find the value of 8.3*24.2*0.03 and round it to the nearest hundredth. So lets multiply the numbers first: 8.03 * 24.2 * 0.03 = 6.0258 and now we need to round it to the nearest hundreth. The nearest hundreth is .03 and we get: 6.03 so the correct answer is D.</span>
<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
