3 ducks and 4 chickens weigh 76kg. 4 ducks and 3 chickens weigh 78kg. All ducks weigh the same and all chickens weigh the same. What is the weight of 1 duck and 1 chicken?

The weight of 1 duck = 12 Kg and weight of 1 chicken is 10 Kg.

Step-by-step explanation:

Let the weight of one duck = x

Let the weight of one chicken = y

The weight of 3 ducks and 4 chicken is 76 kg

         ----- (1)

The weight of 4 ducks and 3 chicken is 78 kg

        ------- (2)

Let us multiply equation (1) by 4 and equation (2) by 3

       ------ (3)

        ------ (4)

Subtracting (3) and (4) :

Substituting the value of y in (1):

So the weight of 1 duck = 12 Kg and weight of 1 chicken is 10 Kg.

area = length x width

length = 2 x width

32 = 2 x width x width

32 = 2 x width^2

36 = width ^2  

width = 6

length = 12

area is 32

perimeter = 2 x 12 + 2 x 6 = 24 + 12 = 36

step-by-step explanation:

the population of other specie of birds will decline or other specie of birds will find some alternate source of food to survive.

explanation:

according to the competitive exclusion principle, which is also known as gause's law, two specie living in the same niche and feeding on the same resource cannot co-exist stably.

as we have well studied the theory of natural selection which states that only those organisms survive which have better tendency to compete for food and adapt to the environmental conditions.

coming towards the question, what wi ll happen when one species outcompetes the other for the small fish , the other specie will not get enough food and will start to die or decline in population. eventually either other specie needs to find another alternative food source for itself or migrate at some other location where there is less competition otherwise it will just not exist anymore at that niche.

hope it !
