Determine the constant of proportionality for each relationship. Note: A relationship that is not a direct variation won't have a constant proportionality select the correct answer from each drop down menu

For the table- k=2

For the graph- no constant of proportionality

For the coordinates- k=3/2

Step-by-step explanation:

I got it all correct.

42.4 6th grade students prefer hip hop

step-by-step explanation:

40 percent of 106 = 42.4

look at the picture.

1.

ef : ab = 2 : 3

gf : cb = 2 : 3

gh : cd = 2 : 3

he : da = 2 : 3

2.

∠a ≅ ∠e

∠b ≅ ∠f

∠c ≅ ∠g

∠d ≅ ∠h

3.

use pythagorean theorem:

the length of the abcd trapezoid sides:

|ab| = 3 cm

|bc| = 10 cm

|cd| = 3(3) cm = 9 cm

|da| = 8 cm

the perimeter of abcd = 3 + 10 + 9 + 8 = 30 cm

the ratio of perimeters of the tarapezoids is equal 2 : 3.

substitute:

      cross multiply

      divide both sides by 3
