Answer:
231
Step-by-step explanation:
Given
Cross Multiply
Therefore x=231
That is written verbally.
In standard form, that would be:
d + 12 / 3
Find the area of a regular hexagon with an apothem 10.4 yards long and a side 12 yards long. Round your answer to the nearest tenth.
The cost of the printer is $309 and cost of the computer is $618.
Step-by-step explanation:
Let x denote the cost of computer
Let y denote the cost of printer
Total cost of printer and computer OR
x + y = $927
<u>To find the cost of x and y,</u>
Cost of computer = 2 x cost of the planet
x = 2y
x+y = 927
2y+y = 927
3y = 927
y = 309
x = 2y
x = 2(309)
x = 618
Therefore, the cost of the printer is $309 and cost of the computer is $618.

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
