Z varies inversely as w ⇒ z*w=k
when z=7 and w=8 ⇒ 7*8=56=k
when w=14 ⇒ z*14=56
⇒z=56/14
⇒ z=4
The smaller wheel rolled
.. 4*2πr = 8πr . . . . feet
The larger wheel rolled
.. 4*2π*2r = 16πr . . feet
The larger wheel traveled (16πr -8πr) = 8πr feet farther than the small wheel.
Answer: Iron, a solid at room temperature, becomes a liquid at 2800 degrees Fahrenheit (really, REALLY hot) and a gas at 5182 degrees Fahrenheit (about half the temperature of the sun). When things are hot, the molecules and atoms move around more and faster, and when they are cold they are slower.
