Question

В резервуаре 3150 л воды. Ежедневно, для орошения, 450 л воды. Напишите формулу, выражающую функциональную зависимость оставшейся воды в резервуаре после ежедневного потребления. Через сколько дней в резервуаре останется 1350 л воды? Через сколько дней резервуар будет пуст? используют

Answer 1

Ответ:

1)через 4 дня в резервуаре будет 1350л

3150-1350 = 1800

1800:450 = 4

2) 3150:450=7

через 7 дней резервуар будет пуст

Объяснение:

Answer 2

Functional Dependency Formula for Remaining Water in the Reservoir

To express the functional dependency of the remaining water in the reservoir after daily consumption, we can use the following formula:

Remaining water = Initial water - (Daily consumption * Number of days)

In this case, the initial water in the reservoir is 3150 liters, and the daily consumption is 450 liters. Let's use this formula to calculate the number of days it will take for the reservoir to have 1350 liters of water remaining and when it will be empty.

Calculation for 1350 Liters of Remaining Water

To find out how many days it will take for the reservoir to have 1350 liters of water remaining, we can rearrange the formula as follows:

Number of days = (Initial water - Remaining water) / Daily consumption

Substituting the given values into the formula:

Number of days = (3150 - 1350) / 450 = 1800 / 450 = 4 days

Therefore, it will take 4 days for the reservoir to have 1350 liters of water remaining.

Calculation for Empty Reservoir

To determine when the reservoir will be empty, we can set the remaining water to 0 in the formula:

Number of days = (Initial water - 0) / Daily consumption

Substituting the given values into the formula:

Number of days = 3150 / 450 = 7 days

Therefore, the reservoir will be empty after 7 days.

Please note that the calculations provided above are based on the given information and assume a constant daily consumption rate.
