The answer to the area of the triangle is 21 because the base is equal to 6 and the height is 7 so you multiply 6 times 7 then divided by 2 because a triangle is 1 half of a square

Answer:

$\frac{136}{999}$

Step-by-step explanation:

We require 2 equations with the repeating decimal after the decimal point in both equations.

The bar above 136 indicates that 136 is being repeated

let x = 0.136136...... → (1) Multiply both sides by 1000

1000x = 136.136.... → (2)

Subtract (1) from (2) to eliminate the decimal part

999x = 136 ( divide both sides by 999 )

x = $\frac{136}{999}$

The radius of the Earth is approximately 3,960 miles. Find the approximate surface-area-to-volume ratio of the Earth.

Jobisdone [24]

To put it another way, that ratio exists, no matter what distance units you use to express lengths, such as the radius of the Earth, but using different units will result in a different numerical part.
You can't, for instance, say the the radius of the Earth is 3960, and leave it at that. 
If someone comes along who's measuring everything in km, he'll tell you that it's 6373. 
Or if he's using meters, he'll say it's 6,373,000. 
Or in yards, 6,969,600. 

So r = 3960 mi 
And as others have said, the area, A, and volume, V, of a sphere, in terms of its radius, are 
A = 4πr² 
V = 4πr³/3 
so that the area to volume ratio is 
A/V = 3/r 

So the answer is 
3/(3960 mi) = (1/1320) /mi.
