Hello! 
The answer is: 15 mL
Why?
From the statement we have that 250 mg need to be given every 8 hours, we can calculate how many mg will be given each day (24 hours):

So,
 a day
 a day
We also know that there are 50 mg cefaclor every 1mL,
So, to know how many mL will be given with 750mg, we just need to divide it by 50

Therefore,
15mL or 750 mg of cefaclor will be given each day.
Have a nice day!
 
        
             
        
        
        
Answer:
9 1/5
Step-by-step explanation:
 3 2/7 * 2 4/5
Change to improper fractions
( 7*3+2)/7  * ( 5*2+4)/5
23/7 * 14/5
Rewriting
14/7 * 23/5
2 * 23/5
46/5
Changing back to a mixed number
5 goes into 45 9 times with 1 left over
9 1/5
 
        
                    
             
        
        
        
Answer:
in this form, the "-r" would cause the result to decrease
I assume that the answer is "r"
if r = .1 (10 %) then 1-.1 = .9
if you have 100 items then y = 100(.9)^1 = 90
the total decreased by 10% ... y = 100(.9)^2 after 2 time periods
