A proportional relationship is identified using a graph, table, or equation. A graph of a proportional relationship will show a straight line that extends through the origin (0, 0). It can also be represented in an equation that relates two numbers or variables with the unit rate of change. Percent Scale drawings Scale factor Unit 4: Geometry A bicycle training wheel has a radius of 3 inches. The bicycle wheel has a radius of 10 inches. Approximately how much smaller, in square inches, is the area of the training wheel than the area of the regular wheel? 21.98 c. 285.74 153.86 d. 1,142.96 Lequan is giving a book as a gift. She will put the book in a box and wrap it. Both the book and box are shaped like rectangular prisms with the dimensions shown in the diagrams. Part A: How much empty space will be in the box after Lequan puts the book inside it? _________ cubic inches Part B: What is the minimum amount of wrapping paper needed to completely cover the outside of the box? _________ square inches Consider the diagram of supplementary angles. What is the value of x? 10.4 c. 61.6 52 d. 92 Consider the figure composed of two rectangular prisms. What is the volume of this figure? 32 c. 416 256 d. 7,680 Figure 1 is a right rectangular pyramid, and Figure 2 is a right rectangular prism. Which statement describes the cross-sections of each figure created by the shaded planes? The cross-sections of both figures are rectangles. The cross-sections of both figures are parallelograms that are not rectangles The cross-section of Figure 1 is a triangle, and the cross-section of Figure 2 is a rectangle.
