A person dives into the ocean and finds
Object A at a depth of 7.4 meters. He
records the elevation of Object A as -7.4.
He finds Object B 5.8 meters deeper than
Object A. He finds Object C at the depth
of Object B.
How will the diver record the elevation of
Object C?
A. -9.9
B. -1.2
C. 1.2
D. 9.9

24

step-by-step explanation:

if it takes 8 pounds to make 12 divide 12 by 8 and you get 1.5, 1.5 x 16 = 24

12

step-by-step explanation:

12 + 5 = 17

12x2=24

24-7=17

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

you have to find the same variables -3n - 5n so this would be -3n +(-5n) which equals -9n
