MAP MAP Math (Grades 6-7) 2 — Questions and Answers
Question 1: What defines a proportional relationship between two variables?
- The ratio between the two variables is constant (Correct answer)
- The two variables always add up to the same sum
- One variable is always greater than the other
- The two variables are equal
Correct answer: The ratio between the two variables is constant
In a proportional relationship, the ratio y/x is constant, and the graph passes through the origin.
Question 2: What is the surface area formula for a rectangular prism?
- SA = 2(lw + lh + wh) (Correct answer)
- SA = l x w x h
- SA = 2l + 2w
- SA = l + w + h
Correct answer: SA = 2(lw + lh + wh)
Surface area = 2(length x width + length x height + width x height), since there are three pairs of identical faces.
Question 3: What is the absolute value of -9?
- 9 (Correct answer)
- -9
- 0
- 81
Correct answer: 9
Absolute value is the distance from zero on a number line, so the absolute value of -9 is 9.
Question 4: What is an equation in mathematics?
- A mathematical statement showing that two expressions are equal (Correct answer)
- A mathematical operation without a variable
- A list of numbers in order
- A formula for calculating area
Correct answer: A mathematical statement showing that two expressions are equal
An equation uses an equal sign (=) to show that two expressions have the same value, such as 3x + 5 = 20.
Question 5: What is 25% of 160?
- 40 (Correct answer)
- 32
- 50
- 25
Correct answer: 40
25% = 1/4, so 25% of 160 = 160 / 4 = 40.
Question 6: What is the volume of a cube with a side length of 3 cm?
- 27 cm3 (Correct answer)
- 9 cm3
- 18 cm3
- 12 cm3
Correct answer: 27 cm3
Volume of a cube = side cubed = 3 x 3 x 3 = 27 cm3.
