Answer 1

Table of Water Level in the Bathtub by Hour

| Hour | Water Level (liters) | |------|---------------------| | 1 | 25 | | 2 | 35 | | 3 | 65 | | 4 | 80 | | 5 | 105 | | 6 | 140 | | 7 | 150 | | 8 | 170 | | 9 | 180 |

The table above shows the water level in the bathtub at different hours. The water is being filled by switching the water pressure. The following amounts of water were added sequentially: 25 liters, 10 liters, 30 liters, 15 liters, 25 liters, 35 liters, 10 liters, 20 liters, and 10 liters.

To calculate the water level in the bathtub at each hour, we can add up the amounts of water added at each hour. Starting with an initial water level of 0 liters, we can update the water level by adding the amount of water added at each hour.

Here is the step-by-step calculation:

1. Hour 1: The water level is 0 liters + 25 liters = 25 liters. 2. Hour 2: The water level is 25 liters + 10 liters = 35 liters. 3. Hour 3: The water level is 35 liters + 30 liters = 65 liters. 4. Hour 4: The water level is 65 liters + 15 liters = 80 liters. 5. Hour 5: The water level is 80 liters + 25 liters = 105 liters. 6. Hour 6: The water level is 105 liters + 35 liters = 140 liters. 7. Hour 7: The water level is 140 liters + 10 liters = 150 liters. 8. Hour 8: The water level is 150 liters + 20 liters = 170 liters. 9. Hour 9: The water level is 170 liters + 10 liters = 180 liters.

Therefore, the water level in the bathtub at each hour is as follows:

- Hour 1: 25 liters - Hour 2: 35 liters - Hour 3: 65 liters - Hour 4: 80 liters - Hour 5: 105 liters - Hour 6: 140 liters - Hour 7: 150 liters - Hour 8: 170 liters - Hour 9: 180 liters

Please note that the calculations assume that there is no water loss due to evaporation or leakage during the filling process.
