Eight adults and two children need to cross a river they give one small have available to help them thr boat can hold one adult or two children Everyone in the group is able to row the boat. show how you get them across the river. How many one way trips does it take for the eight adults and two kids across the river?

Please give a detailed explanation​

horizontal translation of 2 units in the positive x direction

vertical translation of 3 units in the positive y direction

6.25 grams

step-by-step explanation:

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
