Extra+Credit+over+February+Break

I will post five extra credit questions on this page. If you respond over break in the discussion section, I will give points for each response. Respond up top where it says discussion. Email if there are any problems: Ms.Napolitano@gmail.com

1- Which area of math we have studied this year do you think you need the most help on before the NYS Math exam on March 10th and 11th? Then write how you think I can help you to feel more confident prior to the test? (1. number sense-- factors, scientific notation, etc. 2. geometry--- circles, surface area, etc. 3-algebra--- equations, expressions, inequalities, etc. 4- statistics-- circle graphs, bar graphs, etc. 5- probability)

2- A circle has an area of 379.94 square cm. Find the circumference of that circle. Then explain the process you used to solve this problem (In clear sentences)

3- ** Monroe uses license plates for its motorcycles. Each license plate consists of one vowel followed by one digit. There are 5 possible vowels and 10 possible digits. Since the zero and the capital O look the same, they cannot be used together. How many different license plates are possible? ** Explain in detail how you found your answer using words, numbers, and/or pictures

4-** Kyle has earned scores of 85, 88, 73, and 80 on the first four math tests. If the final counts as two tests, what score does Kyle need to earn to earn an 85% average for the quarter? ** Explain in detail how you found your answer using words, numbers, and/or pictures

5- ** The two solids have about the same volume. Jeff says that the surface area of the cylinder is less than the surface area of the rectangular solid. Karen disagrees. Who is correct? ** Explain in detail how you found your answer using words, numbers, and/or pictures. Good Luck!
