Answer 1

Ответ: 830 дней

Пошаговое объяснение:1)9*5*24=1080 часов

2)194444:24=810,17 сумов

4)810,17:1080*24=18,06 сумов

5)15000:18,06≈830 дней

Answer 2

To solve this problem, we need to find out how much it costs to use one lamp for one hour and then calculate how many days the given amount of money will last when using 6 lamps for 4 hours each day.

Step 1: Calculate the cost of using one lamp for one hour

- We know that 9 lamps burn for 5 hours each day and the total cost for 24 days is 19,444 sum. - Let's calculate the cost of using one lamp for one hour: - Cost of using one lamp for one hour = (Total cost for 24 days) / (Number of lamps) / (Number of hours per day) - Cost of using one lamp for one hour = 19,444 sum / 9 lamps / 5 hours = 431.98 sum

Step 2: Calculate how many days 15,000 sum will last when using 6 lamps for 4 hours each day

- Now, we need to find out how many days 15,000 sum will last when using 6 lamps for 4 hours each day. - Let's calculate the number of days: - Number of days = (Given amount of money) / (Cost of using one lamp for one hour) / (Number of lamps) / (Number of hours per day) - Number of days = 15,000 sum / 431.98 sum / 6 lamps / 4 hours ≈ 9.93 days

Therefore, 15,000 sum will last for approximately 9.93 days when using 6 lamps for 4 hours each day.
