Exponential decay:How much of a radioactive kind of chromium will be left after 2 months if you start with 96 grams and the half life is 1 month? So we are using the formula A=p times r^t 2) An online recipe has 95000 page views so far. In addition, thAT NUMBER continues to grow 35% every week. How many page views will the recipe have in 10 weeks?

Answer 1
Answer:
Relax, settle down, forget about the problems for a minute, and think
about "half-life" until you're sure you understand what it means.
"Half life"means the length of time it takes for half of the shaky atoms that
you started with to fall apart. If you start with 100 of them, then 50 of them
die in the first half-life. If you start with 2 million of them, then 1 million of
them die in the first half-life. If you start with 2 radioactive atoms, then
one or the other will decay during the first half-life.
In this problem, you started with 96 grams of radioactive chromium.
Half of it ... 48 grams ... decays away in the first half-life.
What happens after that ? Exactly the same thing.
You start the next half-life with 48 grams of radioactive chromium.
Half of that ... 24 grams ... decays away in the next half-life.
After two half-lifes, you have 1/4 of what you started with.

20/10 as a mixed number:
20 ÷ 10 = 2.
10 goes into 20 two times. So 20/10 as a mixed number is a whole number: 2.
20/10 = 2
20 ÷ 10 = 2.
10 goes into 20 two times. So 20/10 as a mixed number is a whole number: 2.
20/10 = 2
First, decide how many times 10 can go into 20. 10 can "fit in" to 20 exactly 2 times. Since there is nothing left over, the "mixed number" is simply 2.
Another way to do this is to just divide the top by bottom, since it will divide evenly.
20/10 = 2.
