Use the inverse variation equation to fill in the table.
Mandarinka [93]

The value of a is  0.10.

The value of b is 20.78.

The value of c is 0.02.

<h3>What are the missing values?</h3>

When two variables have inverse variation, the two variables move in opposite directions. If one variable increases, the other decreases.

p = 8.31 / V

V = 8.31 / p

a = 8.31 / 83.1 = 0.10

b = 8.31 / 0.4 = 20.78

c = 8.31 / 415.5 = 0.02
