Question

Слесарь обработал 6 деталей первую деталь он обрабатывал 23 минуты а каждый следующий на 2 минуты быстрее чем прежде сколько минут потребуется для обработки деталей

Answer 1

1 деталь 23 минуты
2 деталь 23-2=21
3 деталь 21-2= 19
4деталь 19-2= 17
5 деталь 17-2=15
6 деталь 15-2=13
23+21+19+17+15+13= 108 минут
у меня получилось так,буду рада помочь)))

Answer 2

Processing Time for Each Part

To calculate the total time required to process the parts, we can use the information provided. The first part took 23 minutes to process, and each subsequent part took 2 minutes less than the previous one.

Let's denote the time taken to process the first part as t minutes. Then the processing times for the subsequent parts can be represented as: - Second part: t - 2 minutes - Third part: t - 4 minutes - Fourth part: t - 6 minutes - Fifth part: t - 8 minutes - Sixth part: t - 10 minutes

Total Processing Time

The total processing time for all 6 parts can be calculated by adding the processing times for each part.

Total processing time = (t) + (t - 2) + (t - 4) + (t - 6) + (t - 8) + (t - 10)

Simplifying the expression: Total processing time = 6t - 30

Finding the Value of t

To find the value of t, we can use the fact that the total processing time for all 6 parts is given as the sum of the processing times for each part.

Given that the total processing time for all 6 parts is equal to the sum of the processing times for each part, we can set up the equation:

6t - 30 = 23 + (23 - 2) + (23 - 4) + (23 - 6) + (23 - 8) + (23 - 10)

Solving for t: 6t - 30 = 23 + 21 + 19 + 17 + 15 + 13 6t - 30 = 108 6t = 138 t = 23

Answer

Therefore, the time required to process each part is 23 minutes.
