Friday Benchmark Quiz 10-30 AnswerSheet Benchmark Results Focus Problems from Unit 1- 7NS 1. A cake recipe calls for 5 ½ cups of flour, 1 ¾ cup of white sugar, 1 ¾ cup of brown sugar. How many cups of ingredients do you need to use? (NS3) Show your work. What operation will you use? 9 cups 2. Simplify: 20 - (30 - 33) + 12 (NS1d) (Complete parentheses first) (-3) (Do not forget to distribute or multiply the negative sign in front of the parentheses.) - (- 3) = + 3 (a negative times a negative = + ) (Remember the integer rules for adding and subtracting integers) If signs are the same add. If signs are different subtract. Keep the sign of the largest value (number). 20 + 3 + 12 = 35 3. Simplify: 58 - (20 - 33) + 10 (NS1d) = 81 4. Simplify: 78 - (60 - 33) + 15 (NS1d) = 66 5. Lines of latitude are imaginary lines that circle the globe in an eastwest direction. They measure distances north and south of the equator. The equator represents 0 degree latitude. What latitude is opposite of 90 degrees south latitude? (NS1a) A.) -90 south B.) -180 south C.) 90 north D.) 180 north Take a globe or map. Do you see negative values on a map??? No! This makes two of these options impossible!!! When solving math problems, you will sometimes have to use reasoning and logic to find the BEST answer!!! In mathematics you can use + and – values to represent shifts from zero. For this real world application they use the direction (North, South, East, West) to indicate the shift from zero. So NO negative values. Eliminate the impossible answers. This leaves only one direction and value that can be OPPOSITE of north!!!
