Answer:

Ms.Johnson folded <u>120 cards</u> and Ms.Siple folded <u>180 cards</u>.

Step-by-step explanation:

Given:

Ms.Johnson and Ms.Siple were folding report cards to send home to parents. The ratio of number of report cards Ms.Johnson folded to the number of report cards to Ms.Siple folded is 2:3. At the end if the day, Ms.Johnson and Ms.Siple folded a total of 300 report cards.

Now, to get the number of cards each person fold.

As, the ratio is given.

Ms.Johnson folded to the number of report cards to Ms.Siple folded is 2:3.

So, let the number of cards Ms.Johnson folded be 2x.

And, let the number of cards Ms.Siple folded be 3x.

Total number of cards folded by both of them = 300.

According to question:

2x+3x=300\\\5x=300\\\Dividing\ both\ sides\ by\ 5\ we\ get:\\x=60.

Now, to get the number of cards folded by Ms.Johnson and Ms.Siple we substitute the value of x:

Ms.Johnson folded:

2x=2\times60=120.

Ms.Siple folded:

3x=3\times 60=180.

Therefore, Ms.Johnson folded 120 cards and Ms.Siple folded 180 cards.

Faucet A flows at a rate of 100 liters per 5 minutes and Faucet B flows at a rate of 100 liters per 4 minutes into an empty pool
Dmitriy789 [7]

Answer:

It will take both faucets 200 minutes to fill a pool with 9,000 liters of water

Step-by-step explanation:

Here, we want to know the time it will take for both faucets to fill a pool with 9,000 liters of water

What we need here is to have a joint rate for both faucets;

For the first faucet, we have a rate of 100 liters per 5 minutes so this means in a minute;

100/5 = 20 liters per minute

For the second faucet, the per minute rate will be 100/4 = 25 liters per minute

So therefore, the joint rate will be;

25 liters per minute + 20 liters per minute = 45 liters per minute

So the time needed to fill 9,000 liters of water in a pool will be ;

9000 liters/ 45 liters per minute = 200 minutes
