Question

9 ТЫ ИССЛЕДОВАТЕЛЬ Будь внимателен при решении таких задач. Можно ли решить их обычным способом? а) За 5 дней кролики съели 12 кг моркови. На сколько дней им хватит 24 кг моркови при той же норме выдачи моркови в день? 6) За 6 дней корова съела 140 кг корма. На сколько дней ей хватит 70 кг корма при той же норме выдачи в день?​

Answer 1

1) морковки хватит на 10 дней
2)корове хватит на 2 дней
(если не правильно простите меня)

Answer 2

Ответ:кролику хватит на 10 дней а карове незнаю

Пошаговое объяснение:кролику хватит 10 дней потомушто 5 дней он седает 12кг морковки а если добавить ешё 5 дней то будет 24, 12+12=24

Answer 3

Can these problems be solved using the usual method?

Yes, these problems can be solved using the usual method of setting up and solving equations based on the given information. We can use the concept of proportions to solve these problems.

Problem 1: Rabbits and Carrots

The problem states that rabbits ate 12 kg of carrots in 5 days. We need to find out how many days the rabbits can survive on 24 kg of carrots at the same rate of consumption.

Let's assume that the number of days the rabbits can survive on 24 kg of carrots is represented by 'x'. We can set up the following proportion:

12 kg / 5 days = 24 kg / x days

To solve for 'x', we can cross-multiply and solve for 'x':

12 kg * x days = 5 days * 24 kg

12x = 120

Dividing both sides by 12, we get:

x = 10

Therefore, the rabbits will survive for 10 days on 24 kg of carrots at the same rate of consumption.

Problem 2: Cow and Feed

The problem states that a cow ate 140 kg of feed in 6 days. We need to find out how many days the cow can survive on 70 kg of feed at the same rate of consumption.

Let's assume that the number of days the cow can survive on 70 kg of feed is represented by 'y'. We can set up the following proportion:

140 kg / 6 days = 70 kg / y days

To solve for 'y', we can cross-multiply and solve for 'y':

140 kg * y days = 6 days * 70 kg

140y = 420

Dividing both sides by 140, we get:

y = 3

Therefore, the cow will survive for 3 days on 70 kg of feed at the same rate of consumption.
