Question

чтобы накормить 40 кроликов и 6 телят требуется 54 кг сена в день а чтобы накормить 30 кроликов и 10 телят 79 кг сена найд … и сколько килограмм сена необходимо для одного кролика и одного теленка.

Answer 1

Ответ:

кролики сену не едят тогда 6 телят 54 кг а 10 телят79кг

Answer 2

Calculation of Hay Required

To calculate the amount of hay required to feed the animals, we can set up a system of equations based on the given information.

Let's assume that the amount of hay required for one rabbit per day is x kg, and the amount of hay required for one calf per day is y kg.

From the given information, we can set up the following equations:

Equation 1: 40x + 6y = 54 (to feed 40 rabbits and 6 calves) Equation 2: 30x + 10y = 79 (to feed 30 rabbits and 10 calves)

To solve this system of equations, we can use the method of substitution or elimination.

Solving the System of Equations

Let's solve the system of equations using the method of substitution.

From Equation 1, we can express x in terms of y:

40x = 54 - 6y x = (54 - 6y) / 40

Substituting this value of x into Equation 2:

30((54 - 6y) / 40) + 10y = 79

Simplifying the equation:

(1620 - 180y) / 40 + 10y = 79 1620 - 180y + 400y = 3160 220y = 1540 y = 7

Substituting the value of y back into Equation 1 to find x:

40x + 6(7) = 54 40x + 42 = 54 40x = 12 x = 0.3

Therefore, the amount of hay required for one rabbit per day is 0.3 kg, and the amount of hay required for one calf per day is 7 kg.

Conclusion

To feed one rabbit and one calf per day, you would need 0.3 kg of hay for the rabbit and 7 kg of hay for the calf.

Please note that these calculations are based on the given information and the assumption that the amount of hay required per animal is constant.
