ATI TEAS 7 MATHEMATICS PRACTISE EXAM QUESTIONS AND CALCULATED ANSWERS GRADED A+ Which of the following is the percentage equivalent of 0.0016?A. 16% B. 160% C. 1.6% D. 0.16% - D. To derive a ... percentage from a decimal, multiply by 100:0.0016(100) = 0.16% Curtis is taking a road trip through Germany, where all distance signs are in metric. He passes a sign that states the city of Dusseldorf is 45 kilometers away. Approximately howfar is this in miles? A. 42 miles B. 37 miles C. 28 miles D. 16 miles - C. one kilometer is about 0.62 miles,45(0.62) = 27.9 approximately 28 miles On a floor plan drawn at a scale of 1:100, the area of a rectangular room is 30 cm2. What isthe actual area of the room? A. 30,000 cm2 B. 300 m2 C. 3,000 m2 D. 30 m2 - D. Since there are 100 cm in a meter, on a 1:100 scale drawing, each centimeterrepresents one meter. Therefore, an area of one square centimeter on the drawing represents one square meter tin actuality. - Since the area of the room in the scale drawing is 30 cm2, the room's actual area is 30 m2. L/100 x W/100 = 30 cm2 lw/100 = 30 cm2 Area = 300,000 cm2 300,000 cm2 x. 1m/100 cm x 1m/100 cm = 30m2 Mandy can buy 4 containers of yogurt and 3 boxes of crackers for $9.55. She can buy 2 containers of yogurt and 2 boxes of crackers for $5.90. How much does one box of crackerscost? A. $1.75 B. $2.00 C. $2.25 D. $2.50 - C. The situation may be modeled by the system:4x + 3y = 9.55 2x + 2y = 5.90 Multiplying the bottom equation by - 2 gives: 4x + 3y = 9.55 -4x - 4y = -11.80 Addition of the two equations gives - y = -2.25 or y = 2.25. Thus, one box of crackers costs $2.25 9.55-11.80 = -2.25 -y = -2.25 -y/-1 = -2.25/-1 y = 2.25 1. THE NEXT TWO QUESTIONS ARE BASED ON THE FOLLOWING INFORMATION: Pernell's scores on her last five chemistry exams were 81, 92, 87, 89, and 94. What is the approximate average of her scores?A. 81 B. 84 C. 89 D. 91 - C. To find the average of Pernell's scores, add them up and then divide by thenumber of scores (5 in this case). In other words, 81 + 92 + 87 + 89 + 94 = 443 443/5 = 89 [Show More]
