Answer:
13
Step-by-step explanation:
Using Pythagoras Theorem:

Substitute values of a and b:


The length of the missing side is 13.
<span>216,000,000
</span><span>2.2 × 10 to the 3rd power = 2.2 * 10^3 = 2,200
</span>3.1 × 10 to the 7th power = 3.1 * 10^7 = 31,000,000
<span>310,000
Increasing order:
</span>2,200 , 310,000 , 216,000,000 , 31,000,000
So increasing order with original numbers:
2.2 × 10 to the 3rd power, 310,000, <span>216,000,000, 3.1 × 10 to the 7th power</span>
The answer is B
To figure this out, all you have to do is put 2/3 into a ratio with 6 so it looks like 2/3:6 now get rid of the fraction by multiplying both sides by 3/2 to make the left side 1 and the right side 4.
