Answer: B. 10
-5C3 or 5 choose 3 refers to how many combinations are possible from 5 items, taken 3 at a time. To calculate combinations, we will use the formula nCr = n! / r! ... * (n - r)!, where n represents the total number of items, and r represents the number of items being chosen at a time.
-10 is the total number of all possible combinations for choosing 3 elements at a time from 5 distinct elements without considering the order of elements in statistics & probability surveys or experiments. The number of combinations for sample space 5 CHOOSE 3 can also be written as 5C3 in the format of nCr or nCk.

Answer:
13sqrt(2) units
Step-by-step explanation:
LM² = 7² + 17²
LM² = 338
LM = sqrt(338)
LM = 13sqrt(2)
sqrt: square root

Answer: 3 2/3 Yards 
Step-by-step Solution:
 
In order to solve this problem, you'll want to set up a conversion equation. 
 
** 1 Yard = 3 Feet ** 
To convert these measurements you'll need to write this conversion factor as a conversion ratio. Your ratio will be 1 yard / 3 feet. This fraction is actually equal to 1, meaning we can multiply it by any number to convert the units without changing its value. 
You can then solve by using simple division. I will attach a photo of the steps I did by hand. 
** Canceling the units will help avoid confusion ** 
After you reach the 6th step, all you have to do to find your mixed number is see how many times 3 fits into 11. 
3 can go into 11 3 times, with a remainder of 2. Your final answer should be 3 2/3 yards. 
I hope this helps! c:
 
        
             
        
        
        
In order to find the speed at which the boat is traveling, we divide the distance it has traveled by the time elapsed:
2.5/20=0.125 miles/minute
Next, we want to find how long it took for the boat to travel 10 miles. Since it travels 0.125 miles every minute, we just divide:
10/0.125=80
Thus, it took 80 minutes for the boat to reach the bridge
