Hi there!
To get the answer to this question, let's divide the diameter of the Earth by the diameter of Mercury.

We can change this to

Let's solve for each individual fraction

≈ 0.27

= 10
Now, multiply.
0.27 * 10 = 2.7
That's your answer.
Have an awesome day/night! :)

The mean sustained wind velocity has the equation:
v = 6.3 √(1013 - p)
If we are given with the mean sustained wind velocity of 64 m/s, then we can solve for the air pressure using the equation:
64 = 6.3 √(1013 - p)
64/6.3 = √(1013 - p)
10.1587² = 1013 - p
p = 910 millibars
hope this helps!!!!!!!!!!!!
<u>Answer:</u>
a = 8.1
<u>Step-by-step explanation:</u>
Use the cosine rule:

Substituting the values:

⇒ 
⇒ 
We know the rule of change: a b/c= (ac+b):c
So we have 2 7/8= (2x8+7):8= 23/8
and the second: 2 1/4 = (2x4+1):4= 9/4
We do the division: 23/8: 9/4= 23/8 x 4/9= (23x4):(8x9)= 23/18= 1 5/18
ITS B. The range is the stuff in the right circle. So its 245
