Eloise’s rabbit cage is shape like a rectangular prism. the cage has a height of 28 inches and a volume of 8,680 cubic inches. eloise bought a plastic mat for the bottom of the cage. the plastic mat fits the bottom of the cage perfectly. what is the area of the plastic mat on the bottom of the cage?

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?

In triangle △abc, ∠abc=90°, bh is an altitude. find the missing lengths. ah=4 and hc=1, find bh.

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