The dimensions, in inches, of a shipping box at we ship 4 you can be expressed as width x, length x+5, and height 3x-1. the volume is about 7.6ft^3 find the dimensions of the box in inches. round to the nearest inch

This question consists of 2 parts, a and b. marco got a quotient of 70 when he divided 49 by 0.07. part a what is the correct answer to this problem? part b what mistake did marco make? you!

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?
