Teas 7 Math Solved Questions 2023

What is the sum of two negative numbers? - ANSWER-Negative number Which statement is true? The sum of a positive number and a negative number is always negative, The sum of a positive number and a negative number is always positive, The sum of a positive number and a negative number is always zero, None of the above. - ANSWER-None of the above. Place the following numbers in order from greatest to least: 5, -12, 0 - ANSWER-5, 0, -12 Evaluate the expression. 22+(8-3)×5+1 - ANSWER-30 Using the PEMDAS mnemonic, the parenthesis equation can be evaluated as 5 because 8 - 3 = 5. Evaluating the exponent next, 22 is equal to 2 × 2 = 4. Multiplication must be evaluated before the addition within the expression, and 5 × 5 = 25. 4 + 25 + 1 = 30. Which procedure is impossible? - ANSWER-Adding two quantities with different units Which mathematical statement is true? - ANSWER-20 -21 The correct solution is 20 -21. When in doubt, draw a number line and place the numbers on it, recalling that greater numbers are farther right than lesser numbers. Here, note that because a positive number is always greater than a negative number, 20 -21. Which statement is true? A numeral is a symbol that represents a number, A number is a symbol that represents a numeral, Numerals and numbers are the same, None of the above. - ANSWER-A numeral is a symbol that represents a number. What is the difference between two equal numbers? - ANSWER-Zero How many whole numbers are less than 3 but greater than -3? - ANSWER-3 What is the difference between natural numbers and whole numbers? - ANSWER-The whole numbers include zero, but the natural numbers exclude zero. How many millimeters are in a measurement that is 4 centimeters, 3 meters, and 7 millimeters long? (Note that a centimeter is 10 millimeters and a meter is 1,000 millimeters.) - ANSWER-3,047 Evaluate the expression. 3 + 1 - 5 + 2 - 6 - ANSWER--5 This expression only involves addition and subtraction, but its evaluation must go from left to right.3 + 1 - 5 + 2 - 64 - 5 + 2 - 6(- 1) + 2 - 61 - 6-5 A farmer donates carnation flowers to the local elementary school so that each child can bring one home to their family for an upcoming holiday. If the elementary school hosts grades 1−5, and each grade has 8 classrooms of 25 children, how many carnations will the farmer donate? - ANSWER-1,000 Each grade has 200 children and the school hosts 5 grades. The farmer will need to donate 1,000 carnations because 200 × 5 = 1,000. A designer is carpeting the upstairs of a house. One bedroom measures 10 × 13 square feet and another bedroom measures 15 × 12 square feet. If carpets cost $9.64 square foot, and the designer does not need to factor in labor, how much will the project cost rounding up to the nearest whole dollar? - ANSWER-$2,989.00 The total is $2,989.00 because (10 × 13) + (15 × 12) = 310 square feet × ($9.64 sq foot) = $2,988.40. The cost rounded up to the nearest whole dollar would be $2,989.00. Which statement about multiplication is true? - ANSWER-Multiplication is repeated addition. Evaluate the expression to the nearest hundredth. 0.35 × 0.13 - ANSWER-0.05 The exact decimal solution is 0.0455 which must be rounded up to 0.05 to the nearest hundredth Given an expression with no parentheses, which should be evaluated first? Division Addition Subtraction Any of the above - ANSWER-Division The order of operations (recall the mnemonic PEMDAS) requires multiplication and division before addition and subtraction. Which statement best describes a remainder in division? - ANSWER-The portion of a dividend not evenly divisible by the divisor Evaluate the expression to the nearest hundredth. 0.25 × 0.25 - ANSWER-0.06 Using the multiplication algorithm reveals the answer to be 0.0625. The answer must be rounded to the nearest hundredth which rounds the solution value down to 0.06. Evaluate the expression. 462 ÷ 53 - ANSWER-8R38 Because 462 is not evenly divisible by 53, remainder division is necessary. Use the division algorithm to obtain 8R38. The parent volunteers for a football team need to pick up a variety of bottled drinks for their players. They buy 2 cases of Gatorade and a case of water for everyone which costs $76.50. If each case contains 30 bottles, how much is the value of a single drink? - ANSWER-$0.85 The cost of each drink is valued at $0.85 because there are 90 drinks since each case contains 30 bottles. By dividing the cost by the number of total bottles, it is possible to solve for the individual values. Evaluate the expression. 6 + 8 × 3 ÷ 2 - 7 - ANSWER-11 Using the order of operations, the expression can be rewritten as 6 + 24 ÷ 2 - 7. This can be further rewritten as 6 + 12 - 7. Evaluating this from left to right, 18 - 7 = 11. When dealing with a series of multiplication and division operations, which is the correct approach to evaluating them? - ANSWER-Evaluate the expression from left to right. Evaluate the expression. (−224)÷14 - ANSWER--16 When dividing signed numbers, remember that if the dividend and divisor have different signs, the quotient is negative. Other than the sign, the process is the same as dividing whole numbers. Use the division algorithm to divide 224 by 14. Evaluate the expression. (−224)÷14= - ANSWER--16 When dividing signed numbers, remember that if the dividend and divisor have different signs, the quotient is negative. Other than the sign, the process is the same as dividing whole numbers. Use the division algorithm to divide 224 by 14. A local church partners with local homeless shelters to help feed the homeless on Thanksgiving. The church requires 5 volunteers to help out for every 80 people they serve. Three homeless shelters take care of 200 people total and another two shelters take care of 60 people each. How many volunteers will the church need altogether for the holiday? - ANSWER-20
