b. B varies jointly as D and inversely as M
c. P is directly proportional to Q and inversely proportional to R
d. All of the above

Answer 1

Answer:

a. is the correct option

Answer 2

The situations illustrates combined variations All of the above.

Answer:

• For a connection to be one of combined variation, there must be at least three connected variables.
• In order for the relationship to be one of combined variation, one of the three or more connected variables must directly vary with another and inversely vary with a third.
• The Combined Gas Law, which connects pressure, temperature, volume, and moles (number of molecules) of a gas, is an example of combined variation in the physical universe.
