Answer:
Distance between A ----> B : 2 cm
B ---> C: 3 cm : 600 meters
A----> C: 4 cm
3:600 meters scaled
So its 200 meters per every 1 cm!
From A to B : 400 meters
From B to C : 600 meters
Frok C to A: 800 meters
Therefore we sum 400+600+800= 1800 meters

Answer:
$3.25
Step-by-step explanation:
In an ordinary deck of cards, we will notice that there are 52 cards.
However, we have 4 suits and 13 cards in each one making a total of 52, right?.
So, the probability that a person draws two cards and they will be of the same suit is:
Given that; A person bets 1 dollar to b dollars;
To make the bet fair is;
multiply both sides by 17
4b = 13
b = 13/4
b = 3.25
Therefore, to make the fair, the value of b need to be $3.25
