As a pharmacist, part of your daily duties is to mix medications in the proper proportions for your patients. for one of your regular patients, you always mix medication a with medication b in the same proportion. last week, your patient's doctor indicated that you should mix 110 milligrams of medication a with 154 milligrams of medication b. however this week, the doctor said to only use 126 milligrams of medication b. how many milligrams of medication a should be mixed this week?

110/154 = x/126

154x/13860

x = 13860 /154 = 90

 90 milligrams of medicine A

solution:

→c= a b , that is product of a and b is possible only when when a is m × n matrix and b is n × p matrix.

that is, number of columns of a= number of rows of b.

so, size of matrix , c= a b is , if a = (m × n)matrix

b= (n × p)matrix

then a b = [ (m × n)matrix] ×[   (n × p)matrix ]

→→c= a b= [m × p ] matrix

→→size of product a b will be equal to = number of rows of a × number of columns of b

600,000,000,000, or 6e14
