To find the number of employees we use combination formula.
n!/(n-r)! r!
Put values
11!/(11-3)! 3!
Simplify
11!/8!3! = 165
Answer: Option A 165
1. Change both numbers to common base.
2. Use quotient rule 
e)
You can write 9 as 3², then both numbers have the same base.
, where x is the exponent
I cannot really see the exponents because picture is bad quality.
You want to replace x and y with actual numbers, but as I said the picture is too bad.
f)
Convert to base 4, then quotient rule.
g)
Use the quotient rule, you already have same base.
h)
Convert to base 
, then quotient rule.
Answer:
The solution to the system is (-2,6)
Step-by-step explanation:
I said the solution to the system is (-2,6) because that is where both lines cross, meaning that's the solution.
Hope this is hepful.
Luis skates farther because 2/3 is greater than 2/4 also
2/3=8/12
2/4=6/12
8 is greater than 6
brainlist please im begging you i really need it!!!!!!!!!!!!!!!!!!
