They came stock with a 49T or 48T rear sprocket you can choose a replacement with either a 48T, 49T, 50T, or 51T, if you have the old sprocket count the teeth on the sprocket and that tells if it is a 48T, 49T or whatever (48T = 48 teeth)
That's really very easy, because [ 12t3 - 48t ] isn't a question, so there's no answer needed.All it is is a number, whose value depends on the value of 't'.If your class is working on factoring, then the teacher may give you this expression andask you to factor it. If that's what's happening, then [12t3 - 48t] is not the question.The question is: "What is [12t3 - 48t] in factored form ?" That would be12t (t2 - 4)
one mile
12t(t2-4) 12t(t-2)(t+2)
sqrt[(48t)9] = sqrt(489)*sqrt(t9) = sqrt(488)*sqrt(48)*sqrt(t)*sqrt(t8) = 484*sqrt(48)*sqrt(t)*t4 = 5308416*6.9282*t4*sart(t) = 36777785*t4*sqrt(t)
The GCF is 6.
6t2 - 53t + 40 = 6t2 - 48t - 5t + 40 = 6t(t - 8) - 5(t - 8) = (t - 8)(6t - 5)
The GCF is 9.
The GCF is 4.
The GCF is 30.

48/16 is a decently high road ratio. Pulling a wheelie with that is going to be difficult.
