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

step-by-step explanation:

i don't know

step-by-step explanation:

given perimeter: 28cm

length: 9cm

atp,

2(l+w)=p of the reactangle

2(9+x)=28

18+2x=28

2x=28-18

x=10/2

x=5

therefore width is 5 cm
