The doctor gave his some pick medicine and told him to take 5 milliliters every day until the medicine is finished. There are 60 milliliters of medicine in the bottle. How many days did it take Jay to finish the medicine?

12 days

Step-by-step explanation:

The doctor gives Jay a medicine with 5 milliliters dose per day and he has to use up all 60 milliliters medicine given. To find the number of days needed, we just need to divide the total medicine volume with the volume used per day. The calculation will be:

time needed= total volume used / volume used daily

time needed= 60 ml / (5ml/day)

time needed= 12 days

Jay will need 12 days to finish the medicine.

step-by-step explanation:

calculate the scale factor as the ratio of corresponding sides, image to original, that is

scale factor = = = = 1

7 ft 6 in means 7 1/2, because 6 in is 1/2 of a foot. 7 ft 8 in means 7 2/3 because 8 in is 2/3 of a foot. 23/3 = 7 2/3. 15/2 = 7 1/2.

23/3   *   15/2   = 57 1/2
