First, convert the distance of a typical marathon to kilometers.
1 mi = 1.609 km
26.2 miles = 42.165 km
Divide this distance by Allan's average speed to get his average time.
42.165 km / 12 km/hr = 3.514 hours
Hello there, and thank you for posting your question here on brainly.
So, you need to find the ratio of the following to figure out which one is how to find how many yards are in half a mile.
What would you need to do to find out how? Divide it.
So you'd divide it by what? 2.
Which is the result? C. 880 yd / 1 mi
Hope this helped!! ☺♥
Answer with Step-by-step explanation:
Let F be a field .Suppose 
and 
We have to prove that a has unique multiplicative inverse.
Suppose a has two inverses b and c
Then, 
where 1 =Multiplicative identity
(cancel a on both sides)
Hence, a has unique multiplicative inverse.
Answer:
= 1963.5cm³
Step-by-step explanation:
radius=5
height=25
