The number of bottles, n, needed for the race is n=2h+1, where h is the number of hours she expects to be racing. Which of the following statements is true about the variables n and h ? A.n is the independent variable, and h is the dependent variable. B.h is the independent variable, and n is the dependent variable. C.Both n and h are dependent variables. D.Both n and h are independent variables. B.h is the independent variable, and n is the dependent variable. Tasha has T books, and Aisha has A books. Aisha has twice as many books as Tasha, and altogether they have 30 books. Which of the following proportions can be used to find out how many books Aisha has? A.A:T=2:3A B.T:A=2:3T C.A:(T+A)=2:3 D.T:(T+A)=2:3 C.A:(T+A)=2:3 A. 84 (The surface area of the three-dimensional figure is the sum of the areas of its faces. The faces of the right triangular prism are a 6-by-5 rectangle, a 6-by-4 rectangle, a 6-by-3 rectangle, and two congruent right triangles, each of which has sides of lengths 4 and 3. The areas of the rectangular faces are, respectively, 6×5, or 30; 6×4, or 24; and 6×3, or 18. The area of each of the triangular faces is (1/2)×3×4, or 6. Therefore, the surface area of the figure is 30+24+18+2×6, or 84.) The net shown above forms a right triangular prism. Which of the following represents the surface area of the right triangular prism? A. 84 B. 92 C. 96 D.120 Utensils:$1.50 Cups:$2.00 Plates:$2.00 Tablecloths:$4.50 Above shows the costs of supplies for a birthday party. Anton buys 6 packages of utensils, 4 packages of cups, 2 packages of plates, and 2 packages of tablecloths. Anton's total purchase is subject to a 7.5% sales tax. How much will the party supplies cost Anton? A.$10.75 B.$23.65 C.$30.00 D.$32.25 D.$32.25 A basket contains A apples and P pears, and there are two fewer apples than three times the number of pears. Which of the following equations can be used to represent algebraically the relationship between the number of apples and the number of pears in the basket? A.A=2−3P B.A−2=3P C.A+2=3P D.3A=P−2 C.A+2=3P 30M+15R=900 In a certain year, Rodney earned a total of $900 mowing lawns and raking leaves for his neighbors. He received $30 for each lawn he mowed and $15 for each job raking leaves he had. In the formula above, M represents the number of lawns Rodney mowed for his neighbors and R represents the number of jobs raking leaves he had during the year. If Rodney mowed 15 lawns that year, how many jobs raking leaves did he have? A.15 B.20 C.30 D.90 C.30 Into how many equilateral triangles can a regular hexagon be decomposed?
