The school store sells 2 pencils for 25 cents. If this relationship is graphed with the number of pencils on the x–axis and the cost on the y–axis, what is the constant of proportionality of the graph in cents per pencil?

the bolded word " farsighted" could be replaced with visionary.

answer:

probably the same as it is today since you did not eat the corn dogs yet

step-by-step explanation:

is there supposed to be a picture here?

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
