Fe S  is iron sulfide and has a molar mass  87.91    (Fe 55.845   S 32.06)     100g / (87.91g/mole)  = # moles

1 Mole is 6.022 x 10^23 particles

100 / 87.91   x   6.022 x 10^23 =  number of MOLECULES of FeS

 EACH MOLECULE OF  FeS  has only one ATOM of Fe, so this is the number of Fe atoms.

Since FeS has TWO atoms for each MOLECULE:

The TOTAL number of ATOMS will be double this......     100 / 87.91 x 6.022 x 10^23  x 2  =  # atoms

There are 18 candidates in all....if they are listed in any order without regard to the office for which they are running

18P18 = 6.40237 x 10^15 ways

y-4 = 4x-32

y= 4x - 28           when x = 0    you get the y intercept      y = -28

                           when y=  0 you get the x intercept         x = 7            Sum = -21

4*3 =12

First digit      second digit

2                    4, 6, 7

4                    6, 7, 2

6                    7, 2, 4

7                    2, 4, 6

2^{2x+3}=14     Take log of both sides

(2x+3) Log 2 = log 14     solve for 'x'

x = (log 14/log2 -3  )/2   =  .403677461        Then 2^x = 1.322876

Thanx..... I realized that soon after I posted it and 'fixed' it!!   D'Oh!

FV = PV (1+i)^n 

First scenario  

FV = 20,000 (1.06)^4    If compounded annually

  or just  20,000 + 4*(20000*.06)    If only 6% for the entire four years.

Second scenario

FV = 20,000 (1+ .07/4)^16

I'll let you crunch the numbers to compute the differences !

Since 8 take band AND art ,     17-8 do NOT take art, but only BAND    9

You're welcome !
