Compounds a and b are used in an experiment. the equation a=30,000(12)t represents the remaining amount of compound a, in milligrams, after t seconds. the table shows the remaining amount of compound b. time (sec) mg of b 1 12,000 2 6,000 3 3,000 what is the positive difference in the initial amount of each compound? enter your answer in the box.

6000mg is the difference.

 6000  is the difference between the initial amount of each compound.

Step-by-step explanation:

Since, The equation represents the remaining amount of compound A, in milligrams, after t seconds.

Since initially t =0 sec,

So, the amount by A =

And, According to the given table, we can say that every second the amount by compound B is decreasing to its half.

If In one second the amount by compound B is 12000

therefore, initial amount = 24000

Thus, the total difference between the amount by A and B initially= 30000-24000=6000

she played for 18.75 hours.

step-by-step explanation:

if she played 2/4 of a hour on tuesday. and there is 60 minutes in an hour and 60 divided by 4 is 7.5. and she played 2/4 of an hour on thursday then again 60 divided by 4 is 7.5, you add 7.5+7.5=56.25. now you have to do 1/4 of an hour, it equals 3.75. now you have to add them all up. 3.75+7.5+7.5=18.75
