Two dogs, rufus and daisy, are eating dinner. the amount of food (measured in grams) and rufus's bowl after t minutes is r(t) = 450-150t, and the amount of food (measured in grams) in daisy's bowl after t minutes is d(t)= 400 - 120t. express the ratio of the amount remaining in daisy's bowl to the amount remaining in rufus's bowl as a rational function, and simplify.

A.

Step-by-step explanation:

So we want the ratio of the food amount in Daisy's bowl (D) to the food amount in Rufus's bowl (R) at time t.

So we are asked to do:

Let's see if we can simplify any.

Every single term on top and bottom have a common factor of 10 since they each contain a factor that ends in 0.

I'm going to divide top and bottom by 10:

The answer is A.

I can see no more common factors between 40,12t,45, and 15t:

40=2(2)(2)(5)

12t=2(2)(3)t

45=3(3)(5)

15t=3(5)t

They don't all contain a common factor when looked at altogether.

no this is a nonlinear negative

your answer is -9
