How many solutions are there for the equation sin x = x/100?
A maid was about to wipe the crumbs off a rectangular table measuring 4 ft. by 8 ft. when the butler, a methodical type, took over. “You need a system!” he said. They both had very short arms and could only reach 2 feet with the dust cloth, so the butler decided to get all the crumbs together at center point C along one side. He walked along the opposite side, AB, pushing all the crumbs as far as he could directly toward C, and then did the same thing walking down each end; finally he went to the other long side to pull everything toward the dustpan. When he finished, the maid complained. Why?
Equilateral triangle EKP with side EK of length 2 inches is placed inside square EAMI with side of length 4 inches so that K is on side EA. The triangle is rotated clockwise about K, then P, and so on along the sides of the square until E, K, and P return to their original positions. The length of the path in inches traversed by vertex P is equal to:
and are noncollinear rays (endpoint A). Rhombi are drawn, having one vertex at A, one vertex on , and one vertex on . What is the locus of the fourth vertex?

A notice goes up on the company bulletin board:
“All those who have not already received their subsistence allowance this week should report to the Deputy Assistant Bursar (D.A.B.) at 9 am next Monday, unless they also failed to get it last week, in which case they should not report to anybody anywhere, unless they are over 21 and/or have a maternal grandmother who is still alive, in which case they should either report to the Substantive Acting Registrar at 10 pm on Tuesday or to the D.A.B. at 12 noon on Wednesday according to whether their surname begins with a letter in the first half of the alphabet or not, unless their paternal grandmother does not have or did not have a passport, in which case they should report to the Warden as soon as possible, unless they have already passed their driving test and/or do not have a bicycle, in which case they should take a couple of aspirins and go quietly home to bed.”
Ms. Zola Hooberry, age 20, has not received her subsistence allowance this week or last. She has a bicycle but has not passed her driving test. Both her grandmothers are still alive and have passports.
What should she do?

Here is a card with the four statements that you see, and no others. Assume that each statement on the card is either true or false; then find and identify each false statement. (Refer to them as a, b, c, d if you want, to speed things up.)
Given the two hypotheses:
1. Some yaks are not blats and
2. No blats are blobs,
if “some” means “at least one,” we can conclude that:
- Some yaks are not blobs.
- Some blobs are not yaks.
- No yak is a blob.
- Some yaks are blobs.
- I, II, III, and IV are not deducible from the given statements.
