Answer:
So Cindy can use 5 bags and have 4 marbles in each bag and 5 jacks in each bag.
Step-by-step explanation:
You start by dividing the 20 marbles by 5 and the 25 jacks by 5 since 5 is the GCF. So Cindy can use 5 bags and have 4 marbles in each bag and 5 jacks in each bag. Now each package will have the same number of marbles and each package will have the same number of jacks.
Well she could in theory have a wall of any of those sizes, but most likely A - 10 feet by 22 feet is the correct answer, as it seems most likely for a bedroom wall.
<span> the probability that she rolls an odd number AND and pulls a red chip
so it is = Prob(odd no) * Prob(red chip)
Prob(odd no) for a fair die = 1/2
Prob(red chip) = red chip / total chip = 2/(2+1) = 2/3
so the ans is 1/2 * 2/3 = 1/3

Answer:
- <u>59.0891 g (rounded to 4 decimal places)</u>
Explanation:
<em>Half-life time</em> of a radioactive substance is the time for half of the substance to decay.
Thus, the amount of the radioactive substance that remains after a number n of half-lives is given by:
Where:
- A is the amount that remains of the substance after n half-lives have elapses, and
- A₀ is the starting amount of the substance.
In this problem, you have that the half-live for your sample (polonium-210) is 138 days and the number of days elapsed is 330 days. Thus, the number of half-lives elapsed is:
- 330 days / 138 days = 2.3913
Therefore, the amount of polonium-210 that will be left in 330 days is:
0.3333 as a fraction is 1/3
