Question

Harry is an artist. He paints portraits. The number of paintings he makes can be determined by the equation p = .3b where p is the number of painting and b is the number of paint bottles used. Identify the constant of proportionality.

Answer 1

Answer:

k=0.3

Step-by-step explanation:

-The constant of proportionality  is defined as the ratio between two directly proportional variables.

-Given that p=0.3b

#The constant of proportionality is calculated as:

- the equation can be written in the form y=kx,

where y varies directly with x and k is the constant of variation:

$y=kx\\\\k=\frac{y}{x}\\\\\therefore p=0.3b\\\\\frac{p}{b}=0.3=k\\\\k=0.3$

Hence, the constant of proportionality, k is 0.3
