1 answer:

7 0

Answer In a poligon of n sides can be drawn n-3 diagonals from each vertex.

Explanation The triangle is the first closed polygon, which has three sides and it is not possible to draw any diagonal from a vertex. In a polygon with four sides it is already possible to draw a diagonal from each vertex to the opposite one. Then diagonals = n-3.

A shopkeeper buys two types of tea one at $20 for 10 kg and the other at $23 for 10 kg. He mixes the two types and the mixture i

lorasvet [3.4K]

Let us take the case of first type of tea
Cost of 10 kg of tea one = $20
Then
Cost of 1 kg of tea one = (20/10) dollars
   = 2 dollars
Now let us take the case of the second kind of tea
Cost of 10 kg of tea = $23
Then
Cost of 1 kg of tea = (23/10) dollars
   = 2.3 dollars
So
The mixture of 1 kg of tea one
and 1 kg of second type of tea will cost = (2.0 + 2.3) dollars
      = 4.3 dollars
Then the cost of 2kg mixture of tea costs = 4.3 dollars
So
The cost of 10 kg mixture will cost = (4.3/2) * 10 dollars
   = 4.3 * 5 dollars
      = 21.5 dollars
Then
The amount of profit made by selling 10 kg tea at $38 = (38 - 21.5) dollars
   = 16.5 dollars
So
Percentage of profit made = (16.5/21.5) * 100
   = 1650/21.5
   = 76.74 percent
So the percentage of profit made is 76.74%.
