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:
[tex]y=kx\\\\k=\frac{y}{x}\\\\\therefore p=0.3b\\\\\frac{p}{b}=0.3=k\\\\k=0.3[/tex]
Hence, the constant of proportionality, k is 0.3
