Question

A certain medicine is given in an amount proportional to a patient's body weight. Suppose a patient weighing 164 pounds requires 205
milligrams of medicine. What is the weight of a patient who requires 173.75 milligrams of medicine?

Answer 1

Think: Will the person requiring 173.75 mg of medicine weigh more or less than 164 lb?
Which unit of measurement should your final answer have?
What's the appropriate conversion factor for use in answering this question?

Answer 2

hell weigh more

Answer 3

Agreed. Using the info given in this problem, can you write the ratio of the first person's body weight to the amount of medication (in mg) that the first person requires?
Be certain to include units of measurement in your response.

Answer 4

@triciaal i dont get this can you help?

Answer 5

Sorry you "dont get this." Rather than trying to get another person involved, why don't you recognize that I have given you some appropriate clues and that you are free to ask questions of me?

Answer 6

i cant just read it and understand if you could like get me started by writing it out then i would but just telling me i wont ever get it

Answer 7

Have you tried anything so far? Have you written anything on paper? Have you used "conversion factors" before?

Answer 8

I won't be giving you the answer, by the way, but would gladly give you guidance if only you'd do something towards solving this problem and then share your work with me.

Answer 9

i didnt ask for you to directly give me the answer but the way ur explaining it i wont understand, not that ur teaching is bad its just i learn a different way, i have to see it and i cant see it

Answer 10

Have you considered answering my questions, "Which unit of measurement should your final answer have?
What's the appropriate conversion factor for use in answering this question?" ?

Answer 11

i dont understand what that means

Answer 12

If I were to ask y ou how old you are, how would you respond?

Answer 13

anyways i give up i have other things to be doing , if you asked me id tell you :p

Answer 14

How old are you?

Answer 15

i am 18...whats this have to do with anything?

Answer 16

Plenty. Generally "18" is an OK answer, but you really mean "18 something." What is the appropriate unit of measurement for your age?

Answer 17

18 and 11 months.

Answer 18

right, or, even better, 18 YEARS and 11 MONTHS. years and months are "units of measurement."

You are to determine the body weight of someone who requires 205 mg of medication.
What is the appropriate unit of measurement for body weight in this problem?

Answer 19

214

Answer 20

Not a numeric answer, but a "unit of measurement." Again: You measure your age in YEARS (a unit of measurement); you measure the amount of salt used in a recipe for cookies in CUPS...which is a unit of measurement.

Again, what is the proper unit of measurement for body weight? Hint: the answer is NOT a number, but a "unit of measurement." Re-read the original problem, please.

Answer 21

Hint: What unit of measurement (in the original problem) is associated with the numeric value 164?

Answer 22

"Suppose a patient weighing 164 pounds requires 205 milligrams of medicine."

Answer 23

Sorry, but OpenStudy was 'down' for 5-10 minutes, which is why you didn't hear back from me promptly.

Answer 24

A certain medicine is given in an amount proportional to a patient's body weight. Suppose a patient weighing 164 pounds requires 205 milligrams of medicine. What is the weight of a patient who requires 173.75 milligrams of medicine?

Answer 25

Medicine given is proportional to body weight
medicine = constant* weight
constant = medicine/weight
for 2 given situations
205mg/164 lbs = 173.75mg/x where x is the weight in lbs
solve for x

@dontsmileurugly if someone is trying to help let them know you don't understand
@mathmale please be more considerate! sometimes the person asking is already fustrated with the problem
