5) Токар придумав новий спосіб обробки деталей і за 1 годину стар обточувати на 2 деталі більше,
ніж передбачалося за планом. Тому дейну норму він виконав не за 8 годин, а за 7 годин. Скільки деталей за нормою повинен обробити токар за день?

Ответы на вопрос

Ответ:
Пусть по норме в 1 час должно быть обработано Х деталей, тогда за смену 8Х.
Фактически обрабатывалось (Х+2) деталей в час.Составим обратно пропорциональную зависимость: чем больше деталей обрабатвал, тем меньше времени работал:
Х/(Х+2) = 7 / 8
7Х + 14 = 8Х
7Х - 8Х = - 14
-Х = - 14
Х = 14 (деталей в час по норме) 8Х = 8*14 = 112 (деталей за день по норме)
Ответ: 112 деталей по норме должен обработать токарь за день.

The New Method of Machining and Increased Efficiency
The lathe operator (токар) has come up with a new method of machining parts that allows him to process more parts in a given time frame. According to the information provided, he was able to machine 2 more parts in 1 hour than originally planned. As a result, he completed the standard quota in 7 hours instead of the planned 8 hours.
Calculating the Standard Quota
To determine how many parts the lathe operator should process in a day according to the standard quota, we need to calculate the average number of parts processed per hour. Since the operator completed the standard quota in 7 hours, we can divide the total number of parts by the number of hours to find the average number of parts processed per hour.
Let's assume the standard quota is represented by x parts per day.
According to the information provided, the lathe operator machined 2 more parts in 1 hour than originally planned. Therefore, the average number of parts processed per hour is (x + 2) / 7.
Determining the Number of Parts per Day
To find the number of parts the lathe operator should process in a day according to the standard quota, we need to multiply the average number of parts processed per hour by the number of working hours in a day.
Since the lathe operator completed the standard quota in 7 hours, we can multiply the average number of parts processed per hour by 7 to find the number of parts per day.
Therefore, the number of parts the lathe operator should process in a day according to the standard quota is:
Number of parts per day = (x + 2) / 7 * 7
Simplifying the equation, we can see that the number of parts per day is x + 2.
Conclusion
Based on the information provided, the lathe operator should process x + 2 parts per day according to the standard quota.
Please note that the value of x (the original planned number of parts per day) is not provided in the question, so we cannot determine the exact number of parts the lathe operator should process per day.
