The coldest temperature ever recorded on Earth is 135.8°F below 0, recorded in Antarctica on July 21, 1983. The hottest temperature ever recorded
on Earth is 134°F, recorded in Death Valley, California, on July 10, 1913.
What is the difference between those two temperatures?

-269.8

Step-by-step explanation:

Below 0 is negative.

Them do -135.8 - 134.

the answer is 18 units because there are 18 small cubes inside the rectangle

hope this and p.s i am also in k12

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
