constructed around 210 BC, is made of 3,873,000,000 individual bricks.

2. what is the ingredient found in Cheese Whiz and Krazy Glue? :-\
This is what is is Cheez Whiz: Milk And Part-Skim Milk, Water, Whey,
Milkfat, Sodium Phosphate, Contains Less Than 2% Of Dried Corn Syrup,
Salt, Worcestershire Sauce (Vinegar, Water, Molasses, Corn Syrup,
Salt, Sugar, Caramel Color, Dried Garlic, Spice, Anchovies, Tamarino,
Natural Preservative, Annatto (Color), Oleoresin Paprika, Enzymes

This is the only ingredient for Krazy Glue that I could find:
% by weight
7085-85-0 Ethyl 2-Cyanoacrylate



3. solve this equation

A. Y = Y(3)
y = 0

B. 2 (Y /+ /2YX - 9) = 4
2 (Y /+ /2YX - 9) = 4
2 (y + 2yx – 9) = 4
2y + 4yx -18 = 4
2y + 4yx = 22
y + 2yx = 11

SOLVE FOR Y:
y(1+2x) = 11
y = 11/(1+2x)

SOLVE FOR X:
2yx = 11 – y
x = (11-y) / 2y


4. what accordian player parodied popular rock songs since 1979?
Weird Al

5. were ANY episodes of /THE SIMPSONS /ever rated TV-14-DLSV?
In my book, ALL the episodes are rated, "S," for STUPID.
