Question

Решение задачи В хозяйстве заготовили для коров 17066 центнеров сена из расчета 23 центнеров на корову и 10176 центнеров сена для телят, по 12 центнеров на каждого теленка. Сколько всего коров и телят в хозяйстве?

Answer 1

17066 : 23 = 742 - коровы
10176 : 12 = 848 - телят

Answer 2

1) 17066:23=742 коровы в хозяйстве
2) 10176:12=848- теляет
3) 742+848=1590- всего коров и телят в хозяйстве

Answer 3

Problem Analysis

To solve this problem, we need to determine the number of cows and calves in the farm based on the given information about the amount of hay available for each. Let's break down the problem and find a solution step by step.

Given Information

- The farm has a total of 17,066 centners of hay. - Each cow requires 23 centners of hay. - There are 10,176 centners of hay available for the calves. - Each calf requires 12 centners of hay.

Solution

Let's assume the number of cows as 'x' and the number of calves as 'y'. We can set up the following equations based on the given information:

Equation 1: 23x + 12y = 17,066 (total hay available) Equation 2: x + y = ? (total number of cows and calves)

To find the solution, we need to solve this system of equations.

Solving the System of Equations

To solve the system of equations, we can use substitution or elimination method. Let's use the elimination method in this case.

Multiplying Equation 2 by 12, we get: 12x + 12y = 12 * ? (total number of cows and calves)

Now, we can subtract Equation 1 from this new equation: (12x + 12y) - (23x + 12y) = 12 * ? - 17,066 -11x = 12 * ? - 17,066

Simplifying further: -11x = 12 * ? - 17,066 11x = 17,066 - 12 * ?

Now, we need to find the value of '?'. Let's substitute the given values into the equation.

Substituting Given Values

From the given information, we know that: - 17,066 centners of hay are available in total. - 23 centners of hay are required for each cow. - 10,176 centners of hay are available for the calves. - 12 centners of hay are required for each calf.

Substituting these values into the equation, we get: 11x = 17,066 - 12 * 10,176

Simplifying further: 11x = 17,066 - 122,112 11x = -105,046

Now, we can solve for 'x' (the number of cows): x = -105,046 / 11 x = -9,549.64

Since the number of cows cannot be negative or in decimal form, we can conclude that there is an error in the given information or calculation. Please double-check the values provided.
