Given are three married couples.
So, let us assume there are 3 men and 3 women
They are sitting in a row of 6 empty seats
There is a definite order constraint that each woman will sit left to her husband. The first woman gets 3 options to choose from 3 available seats. The second woman has two options left as already one seat is filled by the first woman. The last woman has one option left. So, it is 
So, number of ways is 3! =
= 6 ways.

Answer:
The Principal is $877.19 And Compound Interest is $372.81
Step-by-step explanation:
Given as :
Amount after investment = $1250
The time period of investment = 6 years
The nominal rate = 6% compounded semiannually
Let the principal = P
From compounded method
Amount = Principal × 
Or, $1250 = P × 
Or, $1250 = P × 
Or, $1250 = P × 1.425
∴ P =
I.e P = $877.19
So , Principal = $877.19
Now, Compound Interest = Amount - Principal
= $1250 - $877.19
Or, CI = $372.81
Hence The Principal is $877.19 And Compound Interest is $372.81 Answer
All the trianges involved are isosceles right triangles. You know that the hypotenuse is the leg multplied by √2.
ML = KM = KL/√2 = 2/√2
ML = KM = √2
Hope that helps, have a good day :)
