Mashutka [201]

Answer:

The answer to your questions are:

15.- 45 mg

16.- 25 kg

17.- 185 pounds

18.- 6 mg

Step-by-step explanation:

                                            D = (a M)  / (a + 12)

15.-

a = 4 years

M = 180

                                      D = (4 x 180) / (4 + 12)  = 720 / 16

                                      D = 45 mg

16.-                                1 pound --------------- 0.4535 kg

                                   55 pounds ------------  x

                                  x = 55 x 0.4535 / 1  

                                 x = 24.94 ≈25 kg

17.-                                1 pound --------------- 0.4535 kg

                                    x             ---------------   84.09 kg

                           x = 84.09x 1 /0.4535

                          x = 185.42 pounds  

18.-  M = 18 mg        what is 1/3 of the adult dose?

                          M = 18/3 = 6 mg
