How to find out the spectrum of petersen graph by mathematica?
(the peterson graph has spectrum 3,-2,-2,-2,-2,1,1,1,1,1 )
explain it step by step.

use an equation of ratios to determine the amount of gas needed to fill the tank.

    0.2             0.8

  =    

288.75             x

                                                              231 gal

so, 0.2x = (0.8)(288.75 gal), and x = = 1155 gal.

                                                                0.2

it would take 1155 gal. to fill the tank.

the cost would be

1155 gal         $3

* = $3465   (answer)

      1           1 gal

hope this you

x> 6

step-by-step explanation:

8x+8> 7x+14

8x-7x> 14-8

x> 6

the volume is the product of the area of the base, 3x(3x+4), and the height, 3x-1
