First convert 2kg to grams which would be 2000g.
Maximum number of books=2000g/200g=10
The maximum number of books she can send is 10.
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.
Add 31 to both sides which will give you
9h = 130
-33=-11*3
-8=-11+3
so
(x-11)(x+3)
Answer:
4
Step-by-step explanation:
2 x 4 = 8
Absolute value means no symbols so it would just be 2 x something equals 8 which is 4.
