A. imagine that you are one of the people who left the luncheon with a contagious disease and interacted with an average of 9 different people each day. how many people could potentially be infected in 7 days? b. imagine the other remaining persons who received the contagious disease at the end of the luncheon interacted with an average of 6 different people per day. how many people could potentially be infected in 7 days by these others who left the luncheon?

1.       In line with the test each person who came into interaction with the infected person will become infected also. With this information, the calculation would be: 9 people each day for 7days would be equivalent to 9 x 7 which equals 63 people.

2.       Here were 7 other people in the experiment if patient zero is left out. If each person intermingled with 6 different people every day in 7 days then the calculation would be: 7 people infected x 6 new people = 42 infected people each day

42 new people every day x 7 days = 294 infected persons.

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

4/6 = 2/3

so it should take 3/3 hours per man. so 9 hours is the answer 3*3 =9
