The number of workers and the time required to finish an amount of work2. The number of workers and the amount of work finished3. The price per kilogram of rice and the number of kilograms4. The number of persons and the amount of food consumption5. The number of family members and the length of time to consume 1 sack of rice

Answer 1

1. IV

2. DV.

3. IV

4. DV

5. IV

Step-by-step explanation:

A direct variation is one in which when one variable increases, the other variable increases as well.

An inverse variation is one in which when one variable increases, the other variable decreases, and vice versa.

Having the definitions of inverse and direct variation in mind, we now go through the examples.

1. As the number of workers increases, the time required to finish an amount of work decreases. Therefore, this is an inverse variation.

2. As the number of workers increases, the amount of work done also increases. Therefore, this is a direct variation.

3. As the price per kilogram of rice increases, the number of kilograms of rice bought also decreases. Therefore, this is an inverse variation.

4. As the number of people increases, the amount of food consumption also increases. Therefore, this is a direct variation.

5. As the number of family members increases, the time required to consume 1 sack of rice decreases. Therefore, this is an inverse variation.

Hence, to summerise,

1. IV

2. DV.

3. IV

4. DV

5. IV
