4. 1. Joann can write 4 problems in 3 minutes. At this rate, about how long will it take her to write 8 sets of 5 problems? Be careful….not all rate problems are set up to solve. Make sure you know exactly how many problems Joann is planning to write! A 30 minutes B 6 minutes C 39 minutes D 53 minutes Correct Answer! Did not multiply: 8 x 5 = 40 problems Solve proportions by cross multiplication Proportion upside down 8 x 5 = 40 Problems440 Minutes3 x CONTINUE CLICKING SCREEN FOR HELP AND HINTS

5. 2. Which of the following is the front view of the 3-D object shown below? FRONT LEFT HGJF Make sure you carefully note where the FRONT of the object is located. Sketch a drawing if you need help. Correct Answer!This is the left view Not sure what this is…This is the top view

6. 3. Which expression represents the perimeter of the isosceles triangle below, in terms of x? ) ) x x + 5 An isosceles triangle has 2 congruent sides and two congruent angles. To find perimeter, find the sum of all sides. Only combine like terms! A 2x + 5 B 3x + 5 C ½(x 2 + 5x) D 3x + 10 Correct Answer! The missing side has a length of x + 5 This used the AREA formula Triangles have 3 sides… CONTINUE CLICKING SCREEN FOR HELP AND HINTS x + 5

7. 4.Find the slope of the linear equation: 12x – 4y = 24 F 12 G -3 H 3 J 2 Correct Answer! OPPOSITE of x over y: -12/-4 = 3 When finding slope, the constant (24) should not be used In standard form, the coefficient on the x is not the slope To find slope, m, from standard form [ax + by = c], use the formula m = -a/b It might be easier to remember to say “opposite of x over y” Slope is the rate of change, and often called rise/run In slope-intercept form [y = mx + b], the coefficient on the x is the slope!

8. 5.What is the ratio of faces to edges of a triangular pyramid? A ratio is a comparison between two numbers A triangular pyramid has a trianglular base and all sides meet in a single point A face is the flat surface of a 3-D object An edge is where two faces meet in a line A 1:1 B 2:3 C 3:2 D 3:4 Correct Answer! Not sure where this came from This is the ratio of edges to faces Ratio of faces to vertices is 1:1 Sketch out a triangular pyramid and then count faces and edges.
