Answer:
<em>There are 20345.556... feet in 6.2 km.</em>
Step-by-step explanation:
Given that, 1 mile = 1.609 km and 1 mile = 5280 ft.
<u>That means we can say</u>, 1.609 km = 5280 ft.
So, 1 km = 
Now, for converting 6.2 km into feet, we will <u>just multiply 6.2 by 3281.541... ft</u>.
Thus, 6.2 km = 
So, there are 20345.556... feet in 6.2 km.
Answer:
12:30
4:10 (simplified)
Step-by-step explanation:
U . v = |u| . |v| cos 60 = 10 * 8 * 0.5 = 40 This is called the scalar (or dot) product.
The ratio being 1:5:3, you would have to just make those numbers still in that ratio, but they have to add up to 180 degrees.The angles would be 20 degrees, 100 degrees, and 60 degrees. Hope that helped. :)
