Question

Первый цех производит 15 деталей в час. второй производит за 8-часовой рабочий день на 10 деталей меньше,чем первый. третий цех производит в день в два раза меньше деталей, чем первый и второй цеха вместе. сколько нужно машин, чтобы вывезти все детали, произведённые в трёх цехах за 8-часовой рабочий день, если на одной машине можно вывести 23 летали

Answer 1

1) 15*8=120 деталей изготавливает первый цех за 8-ми часовой день
2) 120-10=110 деталей изготавливает второй цех за 8-ми часовой день
3) 120+110=230 деталей изготавливают первый и второй  цех вместе
4) 230:2=115 деталей изготавливает третий цех
5) 115+110+120=345 деталей производят три цеха
6) 345:23=15 машин вывезут детали

Ответ 15 машин понадобиться

Answer 2

Problem Analysis

We are given information about three production units or "цеха" that produce a certain number of parts per hour or per day. We need to determine how many machines are required to transport all the parts produced by these units in an 8-hour workday.

Given Information

- The first unit produces 15 parts per hour. - The second unit produces 10 parts less than the first unit in an 8-hour workday. - The third unit produces half the number of parts produced by the first and second units combined.

Solution

To solve this problem, we need to calculate the total number of parts produced by each unit and then determine the number of machines required to transport all the parts.

Let's calculate the number of parts produced by each unit in an 8-hour workday:

- The first unit produces 15 parts per hour, so in 8 hours it produces 15 * 8 = 120 parts. - The second unit produces 10 parts less than the first unit in an 8-hour workday, so it produces 120 - 10 = 110 parts. - The third unit produces half the number of parts produced by the first and second units combined, so it produces (120 + 110) / 2 = 115 parts.

Now, let's calculate the number of machines required to transport all the parts. We are given that each machine can transport 23 parts.

- The total number of parts produced by all three units is 120 + 110 + 115 = 345 parts. - To transport all the parts, we need 345 / 23 = 15 machines.

Therefore, we need 15 machines to transport all the parts produced by the three units in an 8-hour workday.

Answer

To transport all the parts produced in the three units in an 8-hour workday, we need 15 machines.
