Three pipes A, B and C take 24, 36 and 32 hours to fill a pool, respectively. How long would it take the three pipes to fill the

Murrr4er [49]

Answer:

12 hours

Step-by-step explanation:

Time taken by pipe A = 24 hours

Time taken by pipe B = 36 hours

Time taken by pipe C = 32 hours

To find:

How long would it take the three pipes to fill the pool if pipe B is turned on 3 hours after pipe A and pipe C is turned on 1 hour after pipe B?

Solution:

First of all, let us assume the total capacity of the pool.

Let us take LCM of 24, 36 and 32.

LCM of 24, 36 and 32 = 288

Let the total capacity of the pool = 288 units

Total units filled by pipe A in one hour = $\frac{288}{24} = 12\ units$

Total units filled by pipe B in one hour = $\frac{288}{36} = 8\ units$

Total units filled by pipe C in one hour = $\frac{288}{32} = 9\ units$

Now, for the first 3 hours, only pipe A operates, so units filled in first three hours = $12\times 3 =36\ units$

For the next one hour, A and B both operate together, so units filled in the next 1 hour = 12 + 8 = 20 units

Total number of units filled in 4 hours = 36 + 20 = 56 units

Units to be filled to completely fill the pool = 288 - 56 = 232 units

Now, after the 4th hours, all the pipes operate together.

So, number of units filled in each hour = 12 + 8 + 9 = 29 units

Time taken to fill 232 units = $\frac{232}{29} = 8\ hours$

Total time taken = 4 + 8 = 12 hours

UNO [17]

Answer: she played 5 games and went on 8 rides

Step-by-step explanation:

Let x represent the number of games that Sydney played.

Let y represent the number of rides that Sydney went on.

Each game cost $1.25 and each ride cost $2.25. If Sydney spent $24.25 altogether at the carnival, then the expression is

1.25x + 2.25y = 24.25- - - - - - - - - - -1

If the number of rides that she went on is 3 more than the number of games that she played, the expression would be

y = x + 3

Substituting y = x + 3 into equation 1, it becomes

1.25x + 2.25(x + 3) = 24.25

1.25x + 2.25x + 6.75 = 24.25

3.5x = 24.25 - 6.75

3.5x = 17.5

x = 17.5/3.5

x = 5

y = x + 3 = 5 + 3

y = 8

Find the expression that represents the value of v. 2(v - 8) = n+y

Sophie [7]

Answer:

$v = \frac{n+y+16}{2}$

Step-by-step explanation:

2(v-8) = n+y

Distribute

2v-16 = n+y

Move -16 to the other side

2v = n+y+16

Divide everything by 2

$v = \frac{n+y+16}{2}$
