Aveterinarian knows that a 50-pound dog gets 0.5 milligram of a certain medicine, and that the number of milligrams, m, varies directly with the weight of the dog, w. the vet uses these steps to find the amount of medicine to give a 10-pound dog.

0.1 milligrams

Step-by-step explanation:

We have been given that the number of milligrams, m, varies directly with the weight of the dog, w.      

We know that two directly proportional quantities are in form , where y is directly proportional with x and k is constant of proportionality.

Upon substituting our given variables in inversely proportion, we will get:

We have been given that veterinarian knows that a 50-pound dog gets 0.5 milligram of a certain medicine.

Let us find constant of proportionality using our given information.

So our required equation would be .

Now, we will substitute in our equation to solve for medicine needed for a 10-pound dog.

Therefore, the vet will give 0.1 milligrams of medicine to give a 10-pound dog.
