Question 17538: You drop a rock into a deep well. You can't see the rock's impact at the bottom, but you hear it after 6 seconds. The depth of the well is ____feet.
Ignore air resistance. The time that passes after you drop the rock has two components: the time it takes the rock to reach the bottom of the well, and the time that it takes the sound of the impact to travel back to you. Assume the speed of sound is 1100 feet per second.

Question 18886: You are approaching the island of Hawaii in a small boat. The highest point on Hawaii is Mauna Loa at 13,677 feet. You see it just barely above the horizon. The radius of Earth is 3,963 miles. Ignoring atmospheric effects, you figure that you are miles in a straight line from the top of Mauna Loa.

Question 19486: Set up and solve a quadratic equation.
The proportion of the division of a line so that the smaller is to the larger as the larger is to the whole, or of the sides of a rectangle so that the ratio of their difference to the smaller equals that of the smaller to the larger, supposed in classical aesthetic theory to be uniquely pleasing to the eye. ``golden mean, golden section, or extreme and mean ratio, n." Apparently that ``extreme and mean ratio'' is a specific number which is ?

Question 19411: When two resistors S and T are connected in parallel their combined resistance R is given by the expression
R=1/((1/S)+(1/T))
This expression can be rewritten as a rational expression in S and T. The numerator of that expression is ST and its denominator is S+T
Suppose you connect two resistors of the same resistance in parallel. Then the resistance of the two connected resistors equals _________ times that of each resistor alone.

Question 19413: I found the following definition in The Harper Collins Dictionary of Mathematics:
``golden mean, golden section, or extreme and mean ratio, n. the proportion of the division of a line so that the smaller is to the larger as the larger is to the whole, or of the sides of a rectangle so that the ratio of their difference to the smaller equals that of the smaller to the larger, supposed in classical aesthetic theory to be uniquely pleasing to the eye.''
Those Greek were onto something! Apparently that ``extreme and mean ratio'' is a specific number. In fact it is ________. By the way, don't get put off by the above piece of language which is opaque only because of its brevity. The Harper Dictionary of Mathematics is excellent, despite occasional idiosyncrasies. It's also an inexpensive paperback that I use almost every day, and that I recommend highly as an addition to your library.
