There are 1000 grams in a gram and 1000 times 10 is 10000 so yes 100 mg is less than a 10g
Answer:
C.
Step-by-step explanation:
I can explain in comments if needed, but c is the correct answer :)
The question is incomplete, here is the complete question:
Recall that m(t) = m.(1/2)^t/h for radioactive decay, where h is the half-life. Suppose that a 500 g sample of phosphorus-32 decays to 356 g over 7 days. Calculate the half life of the sample.
<u>Answer:</u> The half life of the sample of phosphorus-32 is 
<u>Step-by-step explanation:</u>
The equation used to calculate the half life of the sample is given as:

where,
m(t) = amount of sample after time 't' = 356 g
= initial amount of the sample = 500 g
t = time period = 7 days
h = half life of the sample = ?
Putting values in above equation, we get:

Hence, the half life of the sample of phosphorus-32 is 
Answer:
they payed 3.825 each
Step-by-step explanation:
15% of 51 is 7.65 so you divide that by two and get 3.825
