1. QuestionMultiple choice

A right triangle has legs of 9 and 12 units. What is the length of its hypotenuse?

Please select an answer first.

Correct answer: A

The correct answer is 1515 units.

  1. Identify the quantities and operation: Read the numbers, units, model, table, or diagram carefully and identify what the problem asks you to find.
  2. Use a math strategy: Use the Pythagorean theorem: 9 squared + 12 squared = 81 + 144 = 225, and the square root of 225 is 15.
  3. Check the result: Compare the result with the choices and check whether it is reasonable. The correct answer is 1515 units.

Use the Pythagorean theorem: 9 squared + 12 squared = 81 + 144 = 225, and the square root of 225 is 15.

  1. Identify the quantities and operation: Read the numbers, units, model, table, or diagram carefully and identify what the problem asks you to find.
  2. Use a math strategy: Use V = pi r squared h: 3.14 times 9 times 4 equals 113.04 cubic units.
  3. Check the result: Compare the result with the choices and check whether it is reasonable. The correct answer is 113.04113.04 cubic units.

Use V = pi r squared h: 3.14 times 9 times 4 equals 113.04 cubic units.

3. QuestionMultiple choice

Point (2,−1)(2,-1) is translated 3 units right and 4 units up. What are the new coordinates?

Please select an answer first.

Correct answer: C

The correct answer is (5,3)(5,3).

  1. Identify the quantities and operation: Read the numbers, units, model, table, or diagram carefully and identify what the problem asks you to find.
  2. Use a math strategy: Add 3 to the x-coordinate and 4 to the y-coordinate: (2 + 3, -1 + 4) = (5, 3).
  3. Check the result: Compare the result with the choices and check whether it is reasonable. The correct answer is (5,3)(5,3).

Add 3 to the x-coordinate and 4 to the y-coordinate: (2 + 3, -1 + 4) = (5, 3).

4. QuestionMultiple choice

A square with side length 4 units is dilated by a scale factor of 2. What is the new side length?

Please select an answer first.

Correct answer: D

The correct answer is 88 units.

  1. Identify the quantities and operation: Read the numbers, units, model, table, or diagram carefully and identify what the problem asks you to find.
  2. Use a math strategy: Multiply the original side length by the scale factor: 4 times 2 = 8 units.
  3. Check the result: Compare the result with the choices and check whether it is reasonable. The correct answer is 88 units.

Multiply the original side length by the scale factor: 4 times 2 = 8 units.

5. QuestionMultiple choice

A point (3,2)(3,2) is reflected across the y-axis. What is its image?

Please select an answer first.

Correct answer: A

The correct answer is (−3,2)(-3,2).

  1. Identify the quantities and operation: Read the numbers, units, model, table, or diagram carefully and identify what the problem asks you to find.
  2. Use a math strategy: A reflection across the y-axis changes the sign of x and keeps y unchanged.
  3. Check the result: Compare the result with the choices and check whether it is reasonable. The correct answer is (−3,2)(-3,2).

A reflection across the y-axis changes the sign of x and keeps y unchanged.

6. QuestionMultiple choice

What is the volume of a cone with radius 3 units and height 4 units? Use pi approximately 3.14.
