A. 0.1875% B. 1.875% C. 5.33% D. 18.75% Correct Answer: D Option (D) is correct. The question requires an understanding of percent and percentages. To convert a fraction to a percent, it is necessary to multiply the fraction by 100 and add a percent symbol. Since 316×100=18.75 3 16 × 100 = 18.75, 3 16 is equivalent to 18.75%. Which of the following is equal to 4(5−2)^2 − 2^3 (^ means the digit after ^ is an exponent) A. 16 B. 28 C. 76 D.136 Option (B) is correct. The question requires an understanding of the order of operations. The first step to simplify the expression 4(5−2)^2 − 2^3 is the evaluation of the subtraction within the parentheses; the expression is equivalent to 4 × 3^2 − 2^3 The second step is the evaluation of the powers; the expression is equivalent to 4×9−8 The third step is the evaluation of the multiplication; the expression is equivalent to 36−8 The final step is the evaluation of the subtraction; the expression is equivalent to 28. A two-dimensional net of a certain three-dimensional figure includes five faces, nine edges, and six vertices. Which of the following three-dimensional figures is represented by the net? A. Triangular pyramid B. Triangular prism C. Rectangular pyramid D. Rectangular prism Option (B) is correct. The question requires an understanding of three- dimensional geometry. Triangular pyramids and rectangular prisms have four and six faces, respectively. Triangular prisms have five faces: two are triangles, and three are quadrilaterals. Rectangular pyramids also have five faces: one is a rectangle, and four are triangles. Triangular prisms have nine edges, while rectangular pyramids only have eight edges.
