Jason is traveling by bus from his home to his office. he has gone 5.6 miles so far. from this point on, he can cover 100 miles every 2.5 hours. what is the equation of a line that models the total miles traveled, y, in x hours after this point? (a) y = 5.6x + 100 (b) y = 100x + 5.6 (c) y = -100x + 5.6 (d) y = 40x + 5.6

Asmall (but heavy) particle placed in a glass of water will follow a zigzag motion because the particle will bounce off of the water molecules it meets. this is called brownian motion. a physicist simulates this on a computer, by varying the distance a particle can travel (called the mean free length), on average, before it collides with a water molecule and assigning the change in motion to be one of 8 directions, each with a similar probability. by running the simulated particle (with the same mean free length) many times she determines that it should take 15 seconds, on average, for the particle to fall to the bottom, with a standard deviation of 1.5 seconds. next she lets a real particle fall through a glass of water and finds that it took 18 seconds. what does she conclude, and why?

Asap! i'm not good math and i'm lost.

Suzanne began a trip with 18 1/2 gallons of gas in the gas tank of her car if she hughes 17 3/4 gallons on the trip how many gallons does she have left once she finish the trip
