18. As initation increases, it causes the money you earn today to have: A. more purchasing power in the future
B. no purchasing power effect in the future
C. less value in the future
D. more value in the future

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

5 feet of chain cost $9

so the answer is 1.80

turning oxygen into carbon dioxide.

transitive property

step-by-step explanation:

the definition of the transitive property is:

if a = b, and b = c, then a = b
