PRAXIS Elementary Education: Multiple Subjects Mathmatics (5003) Practice Test Questions (form 3) Graded A+ 1. Which county has a population of 70,000+4,000+70+270,000+4,000+70+2? Answer: Davidson County. 2. What type of mathematical expression is 6x-4? Answer: Algebraic expression. 3. Simplify the expression (2/3)/(4/3)+(3/5)x(5/3)^2. Answer: 13/6. 4. What is the area of a rectangular garden that measures 5(3/4) feet wide by 7(1/2) feet long? Answer: 43(1/8) square feet. 5. How many line segments are in the 10th figure of a pattern? Answer: 35. 6. Which questions are statistical? Answers: A, D 7. What type of angles are found in an equilateral triangle? Answer: Acute. 8. List these distances in order from least to greatest: 1/4 mile, 3/8 mile, 5/6 mile, and 7/12 mile. Answer: B. 1/4 mi, 3/8 mi, 7/12 mi, 5/6 mi 9. Solve the inequality 4x+4≤9x+8. Answer: x≥−4/5 10. Two friends share a dessert and eat 1/2 and 1/3 of it respectively. What fraction of the dessert is left over? Answer: 1/3 11. Which point is located in Quadrant I in the coordinate plane? Answer: Point B The question requires an understanding of how to identify the x-axis, the y-axis, the origin, and the four quadrants in the coordinate plane. The x-axis and the y-axis intersect at the origin and divide the coordinate plane into four quadrants. Quadrant I is the quadrant above the x-axis and to the right of the y-axis. Point B is the only point that lies within this quadrant. 4x(3x+2y) What does 2y represent in the expression shown? A.A binomial B.A factor C.A coefficient D.A monomial ️D. A monomial The question requires an understanding of how to use mathematical terms to identify parts of expressions and describe expressions. A monomial is an algebraic expression that consists of one term that is a number, a variable, or a product of a number and a variable, where all exponents are whole numbers. A unit square is partitioned into identical parts having equal areas. One of the parts is removed from the square, and a shape is formed by the parts that remain after the removal. For which of the following areas of the removed part will the shape that is formed have the greatest area? A. 1/4 B. 1/5 C. 1/6 D. 1/7 ️D. 1/7 The question requires an understanding of how to recognize concepts of rational numbers and their operations. If the unit square is partitioned in n parts having equal area, the area of each part is 1/n. Therefore the area of the shape that is formed when removing one of the identical parts is 1−1/n. The smaller is the area of the removed part, the greater is the area of the shape that is left. Since 1/7 is the smallest of the four fractions listed, the shape that has the greatest area is the one that is left by removing a part with area 1/7. a=5,000(1+r) The formula shown can be used to find the amount of money in dollars, a, in an account at the end of one year when $5,000 is invested at simple annual interest rate r for the year. Which of the following represents the independent variable in the formula? A.a B.5,000 C.r D.1+r ️C. r The question requires an understanding of how to differentiate between dependent and independent variables in formulas. In the given formula, there are two variables, a and r. The formula can be used to investigate how the amount of money a varies depending on the interest rate r. Therefore, the dependent variable is a and the independent variable is r. The surface area of a cube is 54 in^2. What is the volume of the cube? A. 27 in^3 B. 54 in^3 C. 81 in^3 D.108 in3 ️A. 27 in^3 The question requires an understanding of how to solve problems involving elapsed time, money, length, volume, and mass. If the length of the side of the cube is s in, then its surface area is 6s^2 in^2. Since the surface area is 54 in^2, then the length of the side of the cube, in inches, can be found by solving the equation 6s^2=54, which yields s=3. The volume of the cube can then be found by solving the equation V=s^3, thus V=3^3. Therefore the volume is 27 in^3. (0x10^4)+(4x10^3)+(0x10^2)+(5x10^1)+(2x10^0) What number is represented by the base-10 expression shown? ️4,052 The question requires an understanding of how to write numbers using base-10 numerals, number names, and expanded form. Since 10^3=1,000, 10^2=100, and 10^0=1, the expression shown is equivalent to (0)+(4×1,000)+(0)+(5×10)+(2×1)=4,000+50+2(0)+(4×1,000)+(0)+(5×10)+(2×1)=4,000+50+2, which equals 4,052. Which of the following expressions is equivalent to −4(3−2x)?
