1 What is the value of x in the equation 3x + 5 = 20?
Correct Answer:
C
Explanation: To solve for x, subtract 5 from both sides to get 3x = 15. Then divide by 3 to find x = 5.
Explanation: To solve for x, subtract 5 from both sides to get 3x = 15. Then divide by 3 to find x = 5.
2 What is the area of a triangle with a base of 10 cm and a height of 5 cm?
Correct Answer:
C
Explanation: The area of a triangle is calculated using the formula: Area = (base * height) / 2. So, (10 * 5) / 2 = 25 cm².
Explanation: The area of a triangle is calculated using the formula: Area = (base * height) / 2. So, (10 * 5) / 2 = 25 cm².
3 If the perimeter of a square is 36 cm, what is the length of one side?
Correct Answer:
B
Explanation: The perimeter of a square is given by the formula: Perimeter = 4 * side. Therefore, side = Perimeter / 4 = 36 / 4 = 9 cm.
Explanation: The perimeter of a square is given by the formula: Perimeter = 4 * side. Therefore, side = Perimeter / 4 = 36 / 4 = 9 cm.
4 What is the slope of the line represented by the equation y = 2x + 3?
Correct Answer:
C
Explanation: In the slope-intercept form of a line (y = mx + b), m represents the slope. Here, m = 2.
Explanation: In the slope-intercept form of a line (y = mx + b), m represents the slope. Here, m = 2.
5 What is the sum of the interior angles of a pentagon?
Correct Answer:
C
Explanation: The sum of the interior angles of a polygon can be calculated using the formula: (n - 2) * 180°, where n is the number of sides. For a pentagon, n = 5, so (5 - 2) * 180° = 540°.
