Short answer

1. Randall purchased 4 notebooks for $1.39 each and 3 boxes of stick pens for $0.89 each. Write and then evaluate an expression for the total cost of the school supplies.

2. Order the planets in the table below from least to greatest diameter.

Planet Diameter (mi) Venus 7.52 x 103 Uranus 3.18 x 104

Neptune 3.08 x 104 Earth 7.93 x 103

3. The directions on a bag of fertilizer indicate that one bag is enough to

fertilize 0.5 acres. Explain how a farmer could find the number of bags of fertilizer he would need for 42 acres. Then solve.

4. Connect points A(1,2), B(3, 2), and C(2,6) to form a triangle. What type of

triangle is formed? Justify your answer.

5. The Lincoln Memorial has exterior columns. Each marble column is 44 feet tall and has a diameter of 7 feet 5 inches. What is the volume of marble in one column? If necessary, round to the nearest tenth.

6. Roland usually makes three free throws out of every five attempted. To

simulate the probability of Roland making two free throws in a row, Cathy puts 25 marbles in a bag, red for a basket and blue for a miss. After a marble is drawn and recorded, it is replaced. Of the 25 marbles how many should be red?
