Question

В типографии две печатных машины.Они печатают большие листы по 16 страниц на листе.Первая машина за час 7200 листов,вторая 5400 листов сколько экземпляров в 96 страниц можно изготовить из листов напечатанных машинами за 8 часов?

Answer 1

7200*16=115200(стр.)-1машина печатает за час
5400*16=86400(стр.)-2 машина печатает за час
115200+86400=201600(стр.)-вместе печатают за час
201600/96=2100(экз.)-за час
2100*8=16800(экз.)-за восемь часов.
Ответ: 16800 экземпляров за восемь часов.

Answer 2

Calculating the Number of Copies from Printed Sheets

To calculate the number of copies that can be produced from the printed sheets, we can follow these steps:

1. Calculate the total number of pages printed by both machines in 8 hours. 2. Determine the number of copies that can be produced from the total number of pages.

Let's proceed with the calculations:

Step 1: Calculate the Total Number of Pages Printed - The first machine prints 7200 sheets per hour, and the second machine prints 5400 sheets per hour. - Both machines print 16 pages per sheet.

The total number of pages printed by both machines in 8 hours can be calculated as follows: - For the first machine: 7200 sheets/hour * 8 hours * 16 pages/sheet - For the second machine: 5400 sheets/hour * 8 hours * 16 pages/sheet

Step 2: Determine the Number of Copies - Once we have the total number of pages printed, we can calculate the number of copies that can be produced from these pages.

Let's proceed with the calculations and determine the number of copies that can be produced from the printed sheets.

Calculation

- Total number of pages printed by the first machine in 8 hours: 7200 sheets/hour * 8 hours * 16 pages/sheet = 921,600 pages. - Total number of pages printed by the second machine in 8 hours: 5400 sheets/hour * 8 hours * 16 pages/sheet = 691,200 pages.

Now, we can calculate the total number of pages printed by both machines: - Total number of pages printed = 921,600 pages + 691,200 pages = 1,612,800 pages.

To find the number of copies that can be produced from the total number of pages, we need to know the number of pages in a copy. The number of copies that can be produced from the printed sheets can be calculated by dividing the total number of pages by the number of pages in a copy.

Conclusion

Based on the calculations, the number of copies that can be produced from the sheets printed by the machines in 8 hours will depend on the number of pages in each copy. If you have the number of pages in a copy, we can proceed with the final calculation to determine the number of copies.
