  2. The math department wants to reward students who study by buying them IPADs (I). If an IPAD costs $499 each plus a flat rate of $15 shipping. Write an expression, using I, that can be used to find the total cost of the ipads?

  3. $499 per IPAD in addition to the shipping fee will give us the total. 499 I + 15

  4. Mrs. Maes is making spaghetti if she needs 4 cups of noodles for every 3 cups of sauce. How many cups of noodles will she need for 12 cups of sauce?

  5. You will need 16 cups of noodlesSauce : Sauce3: 12Noodles : Noodles4 : ?3 times 4 = 12 (sauce) so4 times 4 = 16 (noodles)

  6. Use the double line graph , to solve how far we will travel in 60 minutes? Distance --------l------------------------l------------ 0 60 miles Time -------l------------------------l------------- 0 60 min 240 min

  7. 15 miles in 60 minutesWhat do you do to 60 minutes to get to 240 minutes? You multiply by 4. With that knowledge, you need a number that is multiplied by 4 to give you 60 minutes. The missing number must be 15.

  8. If I wanted to cut up a cake that is ¾ of a pan into 1/8 pieces, how many pieces would I get?

  9. 6 pieces¾ divided by 1/8We must change the division problem into multiplying ¾ by the reciprocal of 1/8.¾ times 8/1 = 24/4 = 6

  10. If x = 100, What is the value of 4x? What is the value of x to the fourth power?

  11. 4x means four groups of xx + x + x + x100 + 100 + 100 + 100400 x to the fourth power means x * x * x* x (100) (100) (100) (100) 100,000,000 or 100 million

  12. What is the formula to find the area of a triangle?

  13. To find the area of a triangle, one must multiply ½ base (height) Remember to find the h first and then find the base. Do not use a lateral height.

  14. Find length B then find the area of the hexagon. Not drawn to scale.

  15. B = 4cmA = l(W)A = 3(4) 12 cm²A = l(W)A = 4(5) 20 cm²The total area is 12 + 20 = 32 square cm

  16. The area of Mrs. Miller’s BMW picture has an area of 2,400 square feet.List 2 distinct possible dimensions of the picture.

  17. Length and width are dimensions.Area of a rectangle = length times width200(12)= 2400300(8)= 2400400(6)=2400100(24)=240050(48)= 2400etc, etc, etc…..

  18. A rectangle has a length of 8.4cm and a width of 11.06cm. What is the area of the rectangle?

  19. ESTIMATE FIRST8 (11) shows the value must be close to 88. A= length times widthA= 8.4 (11.06) A= 92.904cm²

  20. Find the surface area of the right rectangular prism.SA = 2(lw) + 2(lh) + 2(wh)

  21. SA=2(lw) +2(lh) + 2(wh)2(7*4) + 2( 7*10) + 2( 4*10)2*28 + 2*70 + 2*4056 + 140 + 80276 square centimeters

  22. What is the prime factorization of 300 ?

  23. 300 (3) (100) (3) (10) (10) (3) (2) (5) (2) (5)The prime factorization is 2² × 3 × 5².

  24. What is the formula for volume of a right rectangular prism?

  25. Volume = Length * width* height

  26. Find the volume of the cube.

  27. Since this is a cube, we can use the formula V=s3V= 55 (55)(55)V= 166,375 cm3 Remember, volume is always measured in cubic units. 

  28. Find the Volume of the box.

  29. V = l w h V = (4)(7)(5)V= 20(7) V= 140 in 3

  30. Area measures __________ and volume measures __________.

  31. Area measure covering and volume measures filling.

  32. DAILY DOUBLEFind the area and perimeter of the shaded region.

  33. Perimeter measures the distance around: 5 + 10 + 3 + 7 + 2 + 3 = 30 cmArea measures the amount of covering the total shape minus the white areas.Total shape10(5)=50cm2 , minus the missing sections (2)(2)= 4 and 2(7)=14. Total area of the shaded region is 32cm².

  34. How many snakes are at the zoo?

  35. 29 snakesRemember each dot represents one snake… count the dots to determine the total number of snakes.

  36. Find the mode and the median of the data set.

  37. Mode is 6. (most frequent in a data set).Median is 4. (middle data point in an ordered data set)

  38. What was the range of the quiz scores?

  39. Range is the distance between the extremes.R = 96-40= 56

  40. Find the IQR for the quiz scores? Fin

  41. Lower Extreme :40Quartile one: 59Quartile two: 74Quartile three: 85Upper Extreme: 96IQR= 85-59= 26

  42. The weights of seven people are measured and recorded in the table below: Calculate the Mean Absolute Deviation for their weights.1 60 kg 2 68 kg 3 74 kg 4 78 kg 5 80 kg 6 82 kg 7 90 kg

  43. 49/7= 7 M.A.D

  44. How many more students prefer the Tyrannosaurus to the Stegosaurus?

  45. 4 times as many since 12 is four times larger than 3

  46. Name two similarities and one difference between a bar graph and a histogram.

  47. Which set of data has more variability and why?

  48. The one on the far left is most variable. The graph shows that is spread wider than all the other graphs.

  49. If the following students studied for their exam for .5 hours, .25 hours, 3.5 hours, 4.45 hours, 0 hours, 0 hours, 6.25 hours What is the average amount of time that the students studied for their exam?
