Answer:
Answer of question 1 :
Explanation:
Let x be the legs of ducks
And y be the legs of cows
According to the question,
2x + 4y = 52...…..(i) ( as ducks ahs two legs and as cows has 4 legs)
As he has 21 animals in total so,
x + y = 21...…..(ii)
We have make the equation. We will solve them by eliminatory method or substitution method. Here, I'll go for substitution method.
From equation (ii)
x = 21 - y....…..(iii)
Putting the value of x in equation (i),
2x + 4y = 52
2( 21 - y ) + 4y = 52
42 - 2y + 4y = 52
2y = 52 - 42
y = 10/2
y = 5 ( He has 2 cows)
putting the value of y in equation (ii)
x + y = 21
x + 5 = 21
x = 21 -5
x = 16 ( He has 16 ducks)
or 5 lengths of 234 feet to be cut from a board, the board must have a length of at least 1170 feet.
Let x represent the total length of the board so as to allow for the cutting of 5 lengths.
Since each length needed to be cut is 234 feet, hence:
x = number of lengths × feet per board
x = 5 lengths × 234 feet
x = 1170 feet
Hence for 5 lengths of 234 feet to be cut from a board, the board must have a length of at least 1170 feet.

Number 1 represents the reparation payments from Germany to France and Britain.
<h3>What is the flow of funds?</h3>
The flow of funds implies the movement of money from one person or entity to another. In the case of the international flow of funds, this occurs as money moves from one country to another.
<h3>What does number 1 represent?</h3>
Considering number 1 occurs from Germany to France and Britain, it likely represents reparation payments. This is because by the end of the First World War in 1918 Germany had to pay a lot of money to the countries affected by its war actions, which included France and Britain.
Therefore, money flowed from Germany to France and Britain as shown in the diagram.
