Answer:

After 40 weeks

Step-by-step explanation:

To get the answer to this question, we need to first know the difference in the amount of money deposited by the 2 individuals and in this case it us $400 since one deposited $500 and the other $100

The next thing to do is to divide the difference in amount(400) by the amount contributed by each person per week.

Catherine deposits $20 per week

400/20 = 20

Lance deposits $10 per week

400/10 = 40

The LCM between 40 and 20 is 40 weeks.

Therefore, both individuals need to deposit money for 40 weeks for both of their savings to be the same.

If Catherine deposits $20 for 40 weeks,she will have 40 × 20 = $800 + $100(initial deposit that she made) = $900

Lance deposits $10 for for 40 weeks and he will have 40 × 10 = $400 + $500(initial deposit made by him)= $900

Twenty percent of candies in a package are red. The rest are another color.
kenny6666 [7]

Answer:

  5

Step-by-step explanation:

Among the 20 digits shown, each digit appears in the list twice except 0 and 1 appear 3 times and 6 and 9 appear once. That means ...

  • 1 appears 3 times
  • 2 appears 2 times

So, if 1 and 2 represent red candies, there are 3+2 = 5 red candies in the simulated random sample of 20 candies.

_____

<em>Comment on the question</em>

The simulation makes sense only if it represents taking a single candy from each of 20 packages (of unknown quantity of candies). That is, it seems we cannot answer the question, "how many red candies will be in the packages?" We can only answer the question, "how many of the simulated candies are red?"

If hospital ICU room rates are $784.00 per day, how many days was a patient in ICU if their total room charge is $10,192.00?​
babunello [35]
Answer:
13 days
Step-by-step explanation:
The easiest way to calculate this is to take the total room charge ($10,192.00) and divide by the room rate per dayday ($784.00). This equation looks like 10,192 ÷ 784 = 13
This works out because you are just trying to see how many times that one day charge will fit into the total cost charge.

Hope this helps you out. If you have any questions feel free to comment! :)
