Steven is saving $5 of his earned income, and now has a total of $12,350 in his savings account.
Given that
time required to filled 1/7 of pool = 1/10
so time required to fill 1 pool = 1/10 ÷ 1/7 = 1/10 × 7 = 7/10 hrs
So 0.7 hrs will require to fill the pool at given rate
Answer:
The probability that he will get a red gumdrop and a piece of butterscotch candy is 2/25
Step-by-step explanation:
The path to find the answer is to find the probability of both things happening and then multiply them. First, there is 1 red gumdrop and 4 green gumdrops in a jar. There are 5 gumdrops total so the probability of choosing a red one is 1/5. Next, there are 2 pieces of butterscotch candy and 3 pieces of cinnamon candy in another jar. There are 5 pieces of candy total so the probability of choosing a piece of butterscotch candy is 2/5. Finally multiply the two probabilities: 1/5 * 2/5 = <u>2/25.</u>
6-4(2/3)
5(3/3)-4(2/3)
1(1/3)
Answer:
The equation that describes the amount of mass left after a time t of a radioactive isotope is the following:
where
is the mass of the sample at t = 0
is the half-life of the sample
For the element X in this problem,
We want to find the time t at which
So we need to re-arrange the equation making t the subject:
