Translation into Mathematical Expressions
Rigging your friend's scale so it looks like she's shedding the pounds: being a good friend, or being a total creeper? Translate a word problem into mathematical expressions and find out for yourself. (Our take: don't try this on any of your friends at home.)

to the hair's length. If one of Slash's hairs is 0.7 inches long
and vibrates at 5 Hertz... ...what frequency, in Hertz, would a 0.5 inch
long chest hair have? We start by calling the frequency F and the
length of the chest hair L. The problem tells us that the formula for
the frequency of F is one over L. So F equals K over L, where K is the constant
To find K, we can plug in what we know... ...Frequency is equal to 5 in this instance
and our length is 0.7. By multiplying both sides by 0.7...
...we see that K equals 3.5. So, plugging this new value into our formula...
... the frequency F of a 0.5 inch long chest hair must be...
...7 Hertz. The bad news is that Slash loves Vibradeath's
new sound so much that he has asked his bandmates to start going shirtless as well.
He's really redefining the term "hair band."
