Coach Rowley has determined how many calories he burns while riding his exercise bike. The graph shows the number of calories he burned after biking different numbers of minutes. - Complete each statement.

The calories burned per minute ?

the same for each time period, so the relationship is ?

The constant of proportionality is ?​

answer: c

(2, -4)

goes 7 to the

(9, 4)

easy

6 equilateral triangles

this is a good question! i’ll do some research and what i find, i’ll contact you asap when i have something! ✊

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
