Option 1: Super Tuesday (February 5, 2008 ) has passed and there is still no clear democratic leader in the race for the nomination. The county’s Super Tuesday 2008 turnout set a record with 50 percent of the 362,376 registered voters participating. Prior to 2008, the highest Super Tuesday turnout was in 1988 when 35 percent participated. If the population increased by 5 percent from 1988 to 2008, how many more voters voted in 2008 than in 1988?



Option 2: Once the primary votes are tallied, the states’ delegates are divided up based on the proportion of votes each of the “top” candidates received compared to the other “top” candidates. (“Top” candidates refers to candidates receiving at least 15% of the vote in that state.) In Arizona, Clinton had 51% of the vote and Obama had 42% of the vote. If Arizona has 56 delegates that are tied to the results of the primary, how many delegates did each candidate receive? Disregard any digits after the decimal, and express your answer as a whole number.

Option 3: How many whole numbers less than 1000 contain no 3s but at least one 2?

HAPPY GROUNDHOG'S DAY!

1. Every year on February 2nd in Punxsutawney, PA, Groundhog Phil is called upon to predict how much more winter there will be. If Phil sees his shadow there will be six more weeks of winter, but if he does not see his shadow spring is near. In 2006 Phil saw his shadow. If Phil’s shadow was 25 inches long (when he stands on his back legs) at the same time that a 12 foot tree cast a 15 foot shadow, how tall was Phil, in inches, in 2006?


2. Groundhog Phil’s cousin Henry lives in Moundsville with his family. At the beginning of 2006, Moundsville had a population of 2500 groundhogs but by the beginning of 2008 the population had grown to 3025 groundhogs. If the annual percentage of growth was the same in 2006 as it was in 2007, how many groundhogs lived in Moundsville at the beginning of 2007?


3. Groundhog Henry is digging a new tunnel in a flat field outside of his home. He starts by digging 3 ft straight down and then digs north 4 times the distance that he dug down. At this point Henry digs straight west for 17 ft before running into a boulder. Since he doesn’t know how big the boulder is, he backs up 1 ft and digs 3 ft straight up to the surface. How far is the end of Henry’s tunnel from the beginning of Henry’s tunnel?

Option 1: A pizza restaurant offers circular pepperoni and green pepper pizzas in 3 sizes. The small pizza has diameter 10 inches and sells for $15.20. The medium pizza has diameter 12 inches and sells for $18.85. The large pizza has diameter 14 inches and sells for $22.70. What is the cost per square inch for each size pizza? Express your answer in cents to the nearest whole number.

Option 2: The box for the circular large pizza is a rectangular prism whose length and width are one-half inch greater than the diameter of the circular large pizza and whose height is 1 inch. What is the surface area in square inches of the outside of the box for the circular large pizza?

Option 3: One of the circular large pizzas is placed in the box for a large circular pizza. How many square inches greater is the area of the bottom of the box than the area of the circular large pizza? Express your answer to the nearest whole number.

Option 4: Mr. Reynolds says he will use less material to make a pizza box if he makes a rectangular pizza instead of a circular pizza. He plans to make a rectangular large pizza whose area is equivalent to the area of the circular large pizza in square inches to the nearest whole number. The sides of the rectangular large pizza will be of integer lengths and have the least possible perimeter. The length and width of the bottom and the top of the box will be one-half inch greater than the length and width of the pizza. The sides of the box will be 1 inch high. What is the surface area in square inches of the outside of the box for the rectangular large pizza?

What percent less material will Mr. Reynolds use to make a rectangular large pizza box if he changes from a circular large pizza to a rectangular large pizza of equal area? Express your answer to the nearest whole number.

Comparing with Ratios, Fractions and Percents

2.) Pows- Please pick 2 options. One will count for this week and one for next week.

In the 17th century, Christian Goldbach developed an idea about prime numbers. He stated that every even integer greater than 2 can be written as the sum of two prime numbers. He had strong evidence to support his idea but he was unable to prove that his idea is true. Today this idea is known as Goldbach’s conjecture and still remains to be proven even though there have been many attempts to do so.


OPTION 1: What is the greatest positive difference between two prime numbers whose sum is 18?

OPTION 2: Which two-digit even whole number can be expressed as the sum of two prime numbers whose positive difference is the greatest?

OPTION 3: Another conjecture called the “Weak conjecture” stated by Goldback says that any odd integer greater than 5 can be expressed as the sum of 3 prime numbers. In how many ways can 21 be expressed as the sum of 3 prime numbers?

OPTION 4: In the 18th century Leonhard Euler stated a formula to generate prime numbers. The formula is : P(x) = x2 + x + 17, where x is a whole number. What is the least whole number n such that P(n) is not prime?
