  • Team captains will hand one answer to the table runner.

  • The team captain should be seated in middle of the team.

  • Teams should write answers clearly and neatly so that judges can read answers. Teams with unclear answers will not receive points.

  • Time will begin once the moderator finishes reading the question.

  • Teams should NOT include computational or scratch work on the paper; only answers should be written on the paper.


Quiz bowl

  • Once a team turns in their paper, the team may NOT change their answer.

  • Teams will be provided with scratch paper and pencils as well as their answer sheets.

  • NO books, notes, calculators, or electronic devices, such as cell phones, may be used.

The first team with the correct answer will then receive a follow-up question for 2 bonus points.


Quiz bowl

Q: Find the product:

-9 * -8 * -7 * -6 * -5 * -4 * -3 * -2 * -1 * 0 * 1 * 2 * 3 * 4 * 5 * 6 * 7 * 8 * 9


Solution3

Solution

  • Anything multiplied by 0 is 0, so the answer is 0.


Quiz bowl

F: Find the sum:

-9 + -8 + -7 + -6 + -5 + -4 + -3 + -2 + -1 + 0 + 1 + 2 + 3 + 4 + 5 + 6 + 7 + 8 + 9


Solution4

Solution

  • Still zero… just make pairs of the positive and negative numbers.


Quiz bowl

Q: Solve for x

3(x + 10) = 5(x + 10)


Solution5

Solution

  • 3 (___) = 5 (___) can only be true when both sides equal 0

  • Therefore, x + 10 must equal 0

  • So x = -10


Quiz bowl

F: Solve for x

3(x + 10) + 2 = 5(x + 10)


Solution6

Solution

  • 3 somethings is 2 less than 5 somethings

  • 3 ones is 2 less than 5 ones

  • The statement will be true if (x + 10) = 1

  • x = -9


Quiz bowl

Q: One fourth of the vehicles at Danielle’s Cycle Shop are tricycles. The rest are bicycles. Danielle counted a total of 45 wheels in her shop.

How many bicycles does she have?


Solution7

Solution

  • Every 4 vehicles has 9 wheels: 6 bike wheels and 3 trike wheels

  • There are 5 sets of 9 wheels in 45 wheels

  • She has 4 * 5 = 20 vehicles all together, 15 of which are bikes (3/4 of 20 is 15).


Quiz bowl

F: An outbreak of hoof-and-mouth disease is spreading through the land of Narnia. A vet examines each creature’s mouth and examines each hoof (4 per centaur and 2 per faun). At the end of the day the assistant says, “I need to record how many fauns and how many centaurs we checked.”

Faun

The vet replies, “I didn’t write that down, but I do know I checked 47 mouths and 122 hooves.”

How many centaurs were checked?

Centaur


Solution8

Solution

  • If she checked all fauns (2 legs each) she would have checked 47 * 2 = 94 hooves

  • She checked 122 – 94 = 28 extra hooves

  • That’s 14 extra pairs of hooves

  • Therefore she checked 14 animals with 4 hooves (centaurs).

  • 14 centaurs were checked.


Quiz bowl

Q: Find the product of

0.5 * 0.25 * 0.125

Your answer can be given as a fraction or decimal


Solution9

Solution

  • 0.5 * 0.25 * 0.125 = ½ * ¼ * 1/8

  • ½ * ¼ * 1/8 = 1/(2*4*8)

  • 1/(2*4*8) = 1/(8*8) = 1/64

  • 1/64 = 0.15625


Quiz bowl

F: Evaluate

0.1 + + 0.25 +


Solution10

Solution

0.1 + + 0.25 + =

0.1 + 0.5 + 0.25 + 0.05 =

0.9


Quiz bowl

Q: A jacket is on sale for 25% off. The sale price is $150.00.

How much money do you save by buying the jacket on sale?


Solution11

Solution

  • $150 is 75% of the jacket’s original price

  • $50 is 25% of the jacket’s original price

  • Therefore, you save $50.


Quiz bowl

F: Monica contributes 1/3 of the total cost of a mother’s day present. Nahim contributes ½ of the total cost. Their dad pitches in $9 so they have exactly enough money. How much was Monica’s contribution?


Solution12

Solution

  • Total – ½(Total) – 1/3(Total) = 1/6(Total)

  • $9 was 1/6 of the price.

  • The total price was $54

  • 1/3 of $54 = $18

  • Or, $9 was 1/6 of the price, so 1/3 of the price is 2 * $9 = $18
