1368 roses are packed in cartons that each hold 28 roses. How many cartons will be needed to hold all of the roses?

49 cartons

Step-by-step explanation:

1: we need to find how many cartons the roses will fill so

1368/28 = 48.857 cartons.

2: We can't have .857 of a carton, so we need 49 cartons to hold all the roses.

  21.3

step-by-step explanation:

multiplying the given equation by c/sin(25°), we get

  c = 9/sin(25°) ≈ 21.2958 ≈ 21.3

we assume "c" is the length of ab, the side opposite angle c in triangle abc.
