The given statement is true because the graph represents a direct proportionality between the amount to be paid and the distance traveled by the bus. As the distance increases, the amount to be paid also increases in a consistent and proportional manner.

Since the second room has half the length of the first room, it means that it also has half the area. Since the number of ladrilhos used is directly proportional to the area, we can conclude that the second room will require half the number of ladrilhos. Therefore, the correct answer is 81 ladrilhos.

In the given table, the options are numbers representing the distribution of a lottery prize among the winners. The question asks for the correct number to replace "B" in the table. Looking at the options, 0.50 is the only number that makes sense as it represents an equal division of the prize among the winners. The other options, 0.40, 0.20, and 0.15, do not represent an equal division. Therefore, the correct answer is 0.50.

The distance between Ijuí and Porto Alegre on the map is 2 cm. However, the map is on a scale of 1:10,000,000. This means that 1 cm on the map represents 10,000,000 cm in real life. To find the real distance, we need to multiply the distance on the map by the scale factor. Therefore, the real distance between Ijuí and Porto Alegre is 2 cm * 10,000,000 = 20,000,000 cm, which is equal to 200 km.

To find the time it takes to travel 54km, we can set up a proportion using the given information. Since it takes 2.5 hours to travel 15km, we can set up the proportion: 2.5 hours / 15km = x hours / 54km. Cross-multiplying gives us 15km * x hours = 2.5 hours * 54km. Simplifying, we get 15x = 135. Dividing both sides by 15, we find that x = 9. Therefore, it will take 9 hours to travel 54km.

The value of m is 3 because the numbers in column X are directly proportional to the numbers in column Y. This means that for every increase of 1 in column X, there is an increase of 3 in column Y. Therefore, the value of m, which represents the constant of proportionality, is 3.

The correct answer is 9 chocolates de amêndoa e 15 de avelã. This is because the ratio given is 3:5, which means that for every 3 chocolates de amêndoa, there are 5 chocolates de avelã. Therefore, if there are 24 chocolates in total, we can divide them into 3 parts of amêndoa and 5 parts of avelã. 3 parts of amêndoa would be 3/8 of the total chocolates, which is equal to 9 chocolates. Similarly, 5 parts of avelã would be 5/8 of the total chocolates, which is equal to 15 chocolates.

The correct answer is "Inversamente proporcional à velocidade média." This means that the time taken for the trip is inversely proportional to the average speed. In other words, as the average speed increases, the time taken for the trip decreases, and vice versa. This relationship makes sense because if you are traveling at a higher speed, you will cover the distance between Salvador and Feira de Santana in a shorter amount of time. On the other hand, if you are traveling at a lower speed, it will take you longer to cover the same distance.

If we replace the letter M with any value greater than 12, X and Y will not be inversely proportional.

The scale of the drawing is 1:200, which means that every 1 unit on the drawing represents 200 units in reality. In this case, a length of 4m appears as 2cm on the drawing. Since 1m is equal to 100cm, the length of 4m is equal to 400cm. Therefore, the scale can be calculated as 400cm on the drawing represents 4m in reality, which simplifies to a scale of 1:200.

Se sabemos que 6 gelados custam 9,60, podemos inferir que o valor de cada gelado é 9,60/6 = 1,60. Portanto, se quisermos calcular o preço de 8 gelados, podemos multiplicar o valor de cada gelado por 8, o que resulta em 1,60 * 8 = 12,80. Portanto, 8 gelados custarão 12,80. Isso significa que o valor está aumentando, já que 8 gelados custam mais do que 6 gelados. Além disso, as duas grandezas (número de gelados e preço) estão aumentando na mesma proporção, pois o preço aumenta à medida que o número de gelados aumenta. Portanto, podemos classificar essa relação como diretamente proporcional.

The value of n can be determined by finding the product of the numbers in column X and dividing it by the product of the numbers in column Y. In this case, the product of the numbers in column X is 3 * 4 = 12 and the product of the numbers in column Y is 36 * 48 = 1728. Therefore, n = 12/1728 = 48.

When the number of winners is doubled, the prize is halved for each winner. This implies that the prize is inversely proportional to the number of winners. As the number of winners increases, the prize decreases. Therefore, both statements are true.

The given correct answer states that if we travel 50km, we will have to pay 2 euros, and if we double the distance traveled, the price will also double. This can be inferred from the information provided in the question.
