If we draw some dots on a paper, and connect each one of them to every other one with a single line, how many lines will we draw

Amiraneli [1.4K]

Answer:

Step-by-step explanation:

Let us assume that we have n different dots on a paper. We are to connect pairwise by a line. We have to find out how many lines can be formed.

Let us prove by induction.

If there is one dot then we have no line = 1(1-1) =0

Thus n(n-1) is true for 1 dot

Let us assume that for n dots we have n(n-1) lines

Add one more point now total points are n+1.

Already the existing n points are connected by a line.

So the extra point has to be connected to each of n point

i.e. n lines should be added from the new point to the n points and again n lines from the points to the new point(Assuming lines are different if initial and final point are different)

So 2n lines would be added

So total number of lines for n+1 points

$= n(n-1) +n+n= n^2-n+2n \\= n^2+n\\=n(n+1)$

Thus true for n+1 if true for n. Already true for n =1

So proved by induction for all natural numbers n.

Martin combined different amounts of orange juice, pineapple juice, and strawberry juice to make 1850 milliliters (ml) of fruit

stealth61 [152]

The answer is 450 ml.

First, we need to solve x (the amount of orange juice):
x + (x + 100) + one half x = 1850
x + x + 100 + 1/2 x = 1850

We can represent 1/2 as 0.5:

2x + 100 + 0.5x = 1850
2.5x = 1850 - 100
2.5x = 1750
x = 1750 ÷ 2.5
x = 700.

Thus, in the fruit punch, there is 700 ml of orange juice.

The amount of pineapple juice combined was 100 ml more than the amount of orange juice. Therefore, there is 800 ml of pineapple juice (700 ml of orange juice + 100 ml more).

The amount of strawberry juice was half the amount of orange juice. Therefore, there is 350 ml of strawberry juice (700 ml of orange juice ÷ 2).

The difference in the amounts of pineapple juice and strawberry juice Martin combined is 450 ml:
the amounts of pineapple juice - the amounts of strawberry juice =
800 ml of pineapple juice - 350 ml of strawberry juice = 450 ml.

lukranit [14]

9514 1404 393

Answer:

The (piece, perceived values) are ...

Cindy, (3, 48%)
Jamal, (1, 39%)
Monique, (2, 33%)

Step-by-step explanation:

We assume the values and questions are as shown in the attachment.

1. After the division, Cindy bids only on piece 3, and Jamal bids only on piece 1. Hence the appropriate final division is ...

Cindy: piece 3

Jamal: piece 1

Monique: piece 2

2. Monique divides the land so that the value of each piece to her is 33 1/3%. That is her perceived value for the piece she gets.
