18 - 12 = 6. Because the top legs of the 2 triangles are congruent, you divide 6 / 2 to get 3 as their length. Then you can use the Pythagorean Theorem to solve for x.

3^2 + x^2 = 14^2

9 + x^2 = 196

x^2 = 187

x = sqrt(187)

Dovator [93]

Answer:

$2.6\times 10^{19}m^{3}$

Step-by-step explanation:

we have given thickness of atmosphere =50 km

radius of earth =6400 km

average temperature of atmosphere=15°C

Average pressure of atmosphere= 0.20 atm

we have to calculate the volume of atmosphere

so the we have to calculate the volume of atmosphere = ( volume of earth +atmosphere) - volume of earth

volume of atmosphere = $\frac{4}{3}\times\pi \times \left ( 6400+50 \right )^{3}-\frac{4}{3}\times \pi\times 6400^3$

= $2.6\times 10^{19}m^{3}$

! URGENT ! -1 3/5 ÷ (-2/3) = ?

svetoff [14.1K]

Convert 1 3/5 to an improper fraction;

-1 × 5 + 3/5 ÷ -2/3

Simplify 1 × 5 to 5

-5 + 3/5 ÷ -2/3

Simplify 5 + 3 to 8

-8/5 ÷ -2/3

Use this rule: a ÷ b/c = a × c/b

-8/5 × 3/-2

Use this rule; a/b × c/d = ac/bd

-8 × 3/5 × - 2

Simplify 8 × 3 to 24

-24/5 × -2

Simplify 5 × -2 to -10

- 24/-10

Move the negative sing to the left

-(-24/10)

Simplify 24/10 to 12/5

-(-12/5)

Simplify brackets

12/5

Convert to a mixed fraction

= 2 2/5

-8y=24

We want to isolate y to get the value of 1y. Divide both sides by -8
y= -3

Final answer: y=-3

This is the associative property of addition (D).
It states that when adding three terms, the sum is equal no matter the grouping (parentheses).
