When a train ride is nonstop, the time of the ride is reduced by 1/3. with stops, the time is 18 hours. how long is the nonstop ride?

  Nonstop ride is 12 hours long.

Explanation:

 With stopping time taken by train = 18 hours.

 Without stopping time is reduced by 1/3.

 Time for non stop ride = Time for stopping ride -  (Time for stopping ride/3)

                                        = 2 x Time for stopping ride/3

                                        = 2 x 18 /3 = 12 hours.

 So, nonstop ride is 12 hours long.

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth

step-by-step explanation:

-362

step-by-step explanation:

(12)(4)+2(12)-34(12)+2(12)-3

  \/         \/         \/         \/

  48 +   24 -   408 + 24 - 3

      \   /               \   /

          72     -     432 - 3 = -363
