First you need to subtract 471.41 and 397.46.
471.41 - 397.46= 73.95
The tenths place is the number after the decimal. In number 73.95, the number in the tenths place would be 9. The answer would be C) 74.
(Let me know if you don't understand. I'll try to explain it in more detail.)
I believe you are asking in how many ways they can sit. If so:
The 1st can sit anywhere: he has only 1 way to sit
The 2nd can sit in 11 ways, since one seat is already occupied
The 3rd can sit in 10 ways, since 2 seat are already occupied
The 4th can sit in 9 ways, since 3 seat are already occupied
The 5th can sit in 8 ways, since 4 seat are already occupied
--------------------------------------------------------------------------------
The 12th can sit in 1 way, since11 seat are already occupied
General formula for a circular table:
Number of ways they n persons can be seated: (n-1)!
and the 12 can be seated in (12-1)! = 11! = 39,916,800 ways.
This is called circular permutation
Answer:
x = 4
31x + 6 = 130
12x + 2 = 50
Step-by-step explanation:
two angles side by side are equal to 180.
(31x + 6) + (12x + 2) = 180
43x + 8 = 180
43x = 172
x = 4
31x + 6 = 124 + 4 = 130
12x + 2 = 48 + 2 = 50
