Question

Срочно надо , умоляю, напишите, как делать!!! Продолжительность дня a ч.Чему равна продолжительность ночи? Составьте выражение. Найдите его значение при a= 8; 10; 12.

Answer 1

Я понимаю так.
В сутках всего 24 часа. Соответственно, если продолжительность дня - а часов, то продолжительность ночи - 24-а. Выражение - 24-а.
Теперь. Если а=8, то 24-8=16
Если а=10, то 24-10=14
Если а=12, то 24-12=12.

Answer 2

Duration of Day and Night

The duration of the day and night can be calculated based on the time of sunrise and sunset. The duration of the day is the time between sunrise and sunset, while the duration of the night is the time between sunset and the following sunrise.

Duration of Day: The duration of the day can be calculated by subtracting the time of sunrise from the time of sunset.

Duration of Night: The duration of the night can be calculated by subtracting the time of sunset from the time of the following sunrise.

Expression and Values

The expression for the duration of the day (D) and night (N) can be represented as: - D = Sunset - Sunrise - N = Next Sunrise - Sunset

Values for a = 8, 10, 12

For a = 8: - D = 12 - 8 - N = Next Sunrise - 12

For a = 10: - D = 12 - 10 - N = Next Sunrise - 12

For a = 12: - D = 12 - 12 - N = Next Sunrise - 12

These values can be calculated based on the specific times of sunrise and sunset for the given location and date.

I hope this helps! If you have any further questions, feel free to ask.
