This graph shows a proportional relationship. What is the constant of proportionality?

Enter your answer as a decimal in the box.

The constant of proportionality is 0.3

Step-by-step explanation:

» The graph shows a direct proportiinality.

» Therefore, input the constant;

» When x is 5, y is 1.5:

0.3

Step-by-step explanation:

On a graph, proportional relationships are straight lines that extend through the origin.  

Slope of a graph = constant of proportionality of the equation

Let (5, 1.5) =

Let (20, 6) =

Formula of a slope:

So as the slope = 0.3, the constant of proportionality = 0.3

step-by-step explanation:

there is a formula i can give you:

it is r^2*n*sin(360/n) divided by 2 where r represents the "radius" and n is the number of sides.

plug them in:

(10sqrt(3))^2*6*sin(360/6) divided by 2

100*3*6*sin(60) divided by 2

900*sin(60)

900*sqrt(3)/2

450*sqrt(3)

approx is 779.4 cm^2

answer: $201

step-by-step explanation: to get the answer, you first get 3 nieces that he sold and multiply it by 67 and get $201, so he earned $201 selling his nieces.
