Jade normally leaves work at 5: 00 pm, but she is leaving work 10 minutes late today. she decides to make up time by taking the toll road instead of side streets. she can travel two times faster by taking the toll road. create an equation in terms of x to represent the number of minutes after 5: 00 pm she arrives home from work if she leaves late. let x represent the number of minutes her normal commute takes when she leaves on time.

y equals one half times x minus ten

y = 2x − 10

y = 2x + 10

y equals one half times x plus ten

Three children each had the same amount of money in their savings account. one of the children withdrew three quarters of her moneyand spent it all on a $100 sports jersey. what was the total amount of money originally in the accounts?

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?
