Question

За 8 ч на одном станке изготовили 1456 деталей, а за 9 ч на другом станке - на 470 деталей больше. На каком станке за 1 ч изготовили больше деталей и на сколько деталей больше.

Answer 1

1456:8=182 детали изготовили за час на первом станке
1456+470=1926 деталей изготовили за 9 часов на втором станке
1926:9=214 деталей изготовили на втором станке за 1 час
214-182=32 детали
на 32 детали за 1час изготовили больше на втором станке

Answer 2

1)1456:8=182 изготовили на первом станке за 1 час
2)1456+470=1926 изготавлевает второй за 9 часов.
3)1926:9=214 изготавлевает второй за 1 час .
4) 214-182=32 на столько больше
Ответ: на 32 детали больше.

Answer 3

Problem Analysis

We are given two machines, one that produced 1456 parts in 8 hours and another that produced 470 more parts in 9 hours. We need to determine which machine produced more parts per hour and by how many.

Solution

To find out which machine produced more parts per hour, we can calculate the production rate for each machine.

Let's assume that the first machine produces x parts per hour. Therefore, in 8 hours, it would produce 8x parts.

According to the problem, the second machine produced 470 more parts than the first machine in 9 hours. So, the second machine produced (8x + 470) parts in 9 hours.

To find the production rate of the second machine, we can divide the total number of parts produced by the number of hours. Therefore, the production rate of the second machine is (8x + 470) / 9 parts per hour.

Now, we can compare the production rates of the two machines to determine which one produced more parts per hour.

Calculation

Let's calculate the production rates of the two machines:

- First machine: x parts per hour - Second machine: (8x + 470) / 9 parts per hour

To find out which machine produced more parts per hour, we need to compare the production rates. We can set up the following inequality:

(8x + 470) / 9 > x

To solve this inequality, we can multiply both sides by 9 to eliminate the denominator:

8x + 470 > 9x

Next, we can subtract 8x from both sides:

470 > x

Therefore, the production rate of the second machine, (8x + 470) / 9, is greater than the production rate of the first machine, x, for any value of x less than 470.

Answer

Based on the calculations, the second machine produced more parts per hour. The difference in the number of parts produced per hour between the two machines is 470.
