Question

!!!!!!!!!!!!Срочно!!!!!!!!!!! помогите решить: плавательный бассейн вмещает 525 м3 воды . За один час через первую трубку вливается 30 м3 , а через вторую 25 м3 воды. 1) сколько потребуется времени , чтобы наполнить бассеин. 2) какой объем бассейна останется не заполненым через 3 часа. заранее СПАСИБО!!!!!!!!!!!! даю 35 баллов

Answer 1

1) 525:(30+25) приблизительно = 9,5 (часов) - наполнится бассейн.

2) 525-((30+25)*3) = 360 (м куб.) - останется незаполненным через 3 часа.

Answer 2

Calculation of Time to Fill the Pool

To calculate the time required to fill the pool, we need to determine the rate at which water is being poured into the pool. Given that 30 m3 of water is poured through the first pipe and 25 m3 of water is poured through the second pipe in one hour, we can add these values to find the total rate of water flow:

30 m3/hour + 25 m3/hour = 55 m3/hour

Now, we can divide the total volume of the pool (525 m3) by the rate of water flow (55 m3/hour) to find the time required to fill the pool:

Time to fill the pool = Volume of the pool / Rate of water flow Time to fill the pool = 525 m3 / 55 m3/hour

Let's calculate this:

525 m3 / 55 m3/hour = 9.55 hours

Therefore, it will take approximately 9.55 hours to fill the pool.

Calculation of Remaining Volume after 3 Hours

To calculate the volume of the pool that will remain unfilled after 3 hours, we need to determine the total volume of water poured into the pool in 3 hours. Given that 55 m3 of water is poured into the pool every hour, we can multiply this rate by the number of hours:

55 m3/hour * 3 hours = 165 m3

Now, we can subtract the volume of water poured into the pool in 3 hours from the total volume of the pool to find the remaining volume:

Remaining volume = Total volume of the pool - Volume of water poured in 3 hours Remaining volume = 525 m3 - 165 m3

Let's calculate this:

525 m3 - 165 m3 = 360 m3

Therefore, after 3 hours, there will be approximately 360 m3 of the pool that remains unfilled.

I hope this helps! Let me know if you have any further questions.
