The system of inequalities that best describes this situation provided A represents the area in which the entire field exists:

$$\left \{ {{A \geq x^{2} +10x+300} \atop {A \leq 1200}} \right.$

<h3>What are word problems?</h3>

Word problems in mathematics exist methods we can utilize variables, algebra notations, and arithmetic operations to solve real-life cases.

We have a new addition to the current rectangular field,

Let that new addition to the current rectangular field be x

Length of the new addition = 10x

Twice the width of the new addition = 2x²

Original area of the field = 300

From the above information, we can derive a quadratic equation:

2x² + 10x + 300

Also, we exist given a constraint that the total area of the practice field should be no more than 1200.

It can be less than 1200 or equivalent to 1200.

Therefore, the system of inequalities that best describes this situation provided A represents the area in which the entire field exists:

$$\left \{ {{A \geq x^{2} +10x+300} \atop {A \leq 1200}} \right.$

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 = <em>12 hours</em>
