Answer:

15

Step-by-step explanation:

3 2/4+ 2 3/4+ 2 3/4+ 2 1/4+ 1 1/4+ 1

first add the whole numbers so 3+2+2+2+1+2=12

then we are left with the fractions. 11/4 divides into 2 with a remainder of three so we add it to the top.

From here we have 2/4+3/4+3/4+1/4+3/4

add them together and we get 12/4=3. Then add back our whole numbes to get 12+3=15

Please answer quickly, (1 question, 30 pts) thanks!

Step-by-step explanation:

once the level of medicine reaches a value, where 30% are 23mL (so, whatever is lost, is immediately replaced again), that is then the long run value for the amount of the drug in the patient's body.

so,

30% = 23 mL

1% = 30%/30 = 23/30 = 0.766666666...

100% = 1%×100 = 0.766666666... × 100 = 76.666666...

so, once the level reaches 76.666666... mL in the body, it will remain constant, as the daily filtered out 30% are 23 mL, and the daily add-on is also 23 mL.

so, the answer is

76.667 mL
