Answer:
Vatican
Explanation:
Vatican is the smallest country in Europe by population, but also by area, and not just in Europe, but it is the smallest country by population and area in the whole world. The country occupies only 44 hectares, and it has less then 800 inhabitants. It is also the only country in the world that has a birth rate of 0. The inhabitants of this country are the highest representatives of the Catholic Church, thus the Pope and the cardinals, and the people that work there. This miniature country is located in the central part of Rome, thus it has a border with only one country, Italy. It is a remnant of the Papal city-state that existed in this region, though it is much smaller nowadays. Vatican is the second most holy place for the 1.3 billion Catholics, right behind Jerusalem, and millions of people are visiting this small country every year, some because of religious purposes, while some as tourists.
Answer:
Do you have a friend that can affect your mood? Whenever she's up, you're up. When she's down, you're down. A proportional relationship between quantities is a lot like that. For example, imagine a beehive that has a lot of bees in it. Each of those bees has six legs. If I take away half the bees, there will only be half as many legs left in the hive as well. There is a proportional relationship between the number of bees and the number of bee legs in that hive.
A proportional relationship exists between two values x and y when they can be expressed in the general form y = kx, where k is the constant of proportionality.
Our beehive example could be represented by y = 6x, where x is the number of bees, y is the number of legs, and k is 6 (since each bee has 6 legs). If I double x, then y will also double, and if I divide y by x, then y/x should always be 6.
Another way to say that is if two values are proportional, then dividing them by each other will always produce the same ratio. This ratio will be the constant k, which can be expressed as a fraction or a decimal.
