Answer:
30240 number of ways are there to seat them
Step-by-step explanation:
Total number of ways of arranging 9 people on 9 chairs in circular manners = (9-1)! = 8! =
number of ways A sit always sit next to B = AB together makes a single and
therefore total number of arrangements for this = 7+(AB) = 8 that is 8 persons sitting in circular manner
number of ways = (8-1)! =7! = 5040
likewise number of arrangements for A and C will be = 5040
Total number of ways such that A cannot sit next to B or C = total ways of 9 persons - total number of A always sitting next to B - total number of ways always sitting next to C = 8! - 7!-7!
= 40320- 5040-5040
= 30240
=
#1- irrational
#2- whole
#3- rational
#4- natural and whole
Answer:
we havent learnt those subjects
Step-by-step explanation:
then let me ask my bri
The expression represents a straight line equation of the form y=mx+c. where m is the slope and c is the y-intercept. From the given expression,
m=1.10 and c=0
therefore since a(w)=1.10w+0 is a straight line equation, the domain of the equation will be:
(-∞,∞)
and the range will be:
(-∞,∞)
This is because the domain and range of the straight line is always (-∞,∞).
Answer:D.54
Step-by-step explanation: it takes 20 minutes in the car which is 1/3 of an hr so 42/3= 14 then that leaves 40 minutes left for the train which is 2/3 of 60 and 60/3=20 and 20x2= 40 so 40+14=54
