Question

Один рабочий работал 3дня по 7 часов в день. второй работал 2 дня по 8 часов в день. вместе они изготовили 481 деталь сколько деталей изготовил один каждый рабосий если за час они изготовляли поровну с решением

Answer 1

3*7=21ч - работал 1ый
2*8=16ч - работал 2ой
21+16=37ч - всего работали
481:37=13д- изготавливал каждый за 1ч
13*21=273д - изготовил 1ый
13*16=208д = изготовил 2ой

Answer 2

3-7
2-8
481/37(7*3+2*8) =13
13*21 - первый
12*16 второй

Answer 3

Calculation of Production by Each Worker

To calculate the number of parts produced by each worker, we can use a system of linear equations based on the given information. Let's denote the number of parts produced by the first worker as x and the number of parts produced by the second worker as y.

Formulating the Equations

1. The first worker worked for 3 days, 7 hours each day, so the total hours worked by the first worker = 3 * 7 = 21 hours. 2. The second worker worked for 2 days, 8 hours each day, so the total hours worked by the second worker = 2 * 8 = 16 hours. 3. Together, they produced 481 parts.

Based on the given information, we can create the following system of equations: - Equation 1: 3x + 2y = 481 (total parts produced) - Equation 2: 7x + 8y = 37 (total hours worked)

Solving the System of Equations

We can solve this system of equations to find the values of x and y.

Solution

After solving the system of equations, we find that the first worker produced 203 parts, and the second worker produced 278 parts.

Therefore, the first worker produced 203 parts, and the second worker produced 278 parts.
