Answer 1

14*6=84(кг) сена всего
2)84:7=12(дн)-на 12 дней хватит запаса сена
Ответ:На 12 дней

Answer 2

Problem Analysis

To solve this problem, we need to determine how many days the supply of hay will last if a cow is given 7 kg of hay per day, instead of 6 kg.

Solution

Let's start by calculating the total amount of hay available initially. We know that the supply of hay is enough for 14 days when the cow is given 6 kg of hay per day.

To find the total amount of hay available, we can multiply the amount of hay given per day (6 kg) by the number of days (14):

Total amount of hay available = 6 kg/day * 14 days = 84 kg

Now, we need to determine how many days this supply of hay will last if the cow is given 7 kg of hay per day.

To find the number of days, we can divide the total amount of hay available by the amount of hay given per day (7 kg):

Number of days = Total amount of hay available / Amount of hay given per day = 84 kg / 7 kg/day = 12 days

Therefore, if the cow is given 7 kg of hay per day, the supply of hay will last for 12 days.

Answer

If the cow is given 7 kg of hay per day, the supply of hay will last for 12 days.

Verification

Let's verify the solution by calculating the total amount of hay consumed in 12 days when the cow is given 7 kg of hay per day.

Total amount of hay consumed = Amount of hay given per day * Number of days = 7 kg/day * 12 days = 84 kg

The total amount of hay consumed matches the initial total amount of hay available, which confirms the correctness of the solution.

Therefore, the solution is verified.
