After the first three days, the sample size will be half of the initial; therefore, 400g/2= 200g. However, it is asking how long will it take to decay to 100g, so we will take 200g/2= 100g, which will take another three days. It will take 2 half-lives, which will encompass 6 days.
Answer:

Step-by-step explanation:
To find the LCM of two numbers, factorize both these numbers:

These two numbers have the common factor of 
Now multiply this common factor by the remaining factors:

Therefore, the LCM is 952.
If he does three hours, its 9 strips, for four, its 12, six is 18, seven is 21, and nine is 27
If you divide 36 by 4, it equals 9, so each side is 9. Then you multiply 9 to 9, which equals 81 in^2.
