Annabelle measured her bedroom as 11 ft mr026-1.jpg 13 ft, which is 143 square feet. she wants to change the units to square inches. which statements should she consider when converting? check all that apply.

here are 12 inches in every foot. the length and width will increase by a factor of .the length and width will increase by a factor of .the area will increase by a factor of , since area is length times width. the area will increase by a factor of , since both the length and width increase by that factor. the area will increase by a factor of , since both the length and width increase by that factor. the area will increase by a factor of , since both the length and width increase by that factor.

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?

It is given that the quadratic equation hx²-3x+k=0, where h and k are constants, has roots [tex] \beta \: and \: 2 \beta [/tex]express h in terms of k

Val and tony get paid per project. val is paid a project fee of $44 plus $12 per hour. tony is paid a project fee of $35 plus $15 per hour. write an expression to represent how much a company will pay to hire both to work the same number of hours on a project.
