1. QuestionMultiple choice

A right triangle has legs of 6 units and 8 units. What is the length of the hypotenuse?

Please select an answer first.

Correct answer: A

The correct answer is 10units10 units.

  1. Identify the math idea: Decide whether the question uses linear relationships, numbers, expressions, equations, geometry, statistics, probability, or problem solving.
  2. Show the reasoning: Use the Pythagorean theorem: 6 squared + 8 squared = 36 + 64 = 100, so the hypotenuse is 10.
  3. Check the result: Review the sign, units, operation, and estimate to make sure the answer is reasonable.

Use the Pythagorean theorem: 6 squared + 8 squared = 36 + 64 = 100, so the hypotenuse is 10.

2. QuestionMultiple choice

What is the distance between (−3,2)(−3, 2) and (5,2)(5, 2)?

Please select an answer first.

Correct answer: B

The correct answer is 8units8 units.

  1. Identify the math idea: Decide whether the question uses linear relationships, numbers, expressions, equations, geometry, statistics, probability, or problem solving.
  2. Show the reasoning: The y-coordinates are equal, so subtract the x-coordinates: 5 − (−3) = 8.
  3. Check the result: Review the sign, units, operation, and estimate to make sure the answer is reasonable.

The y-coordinates are equal, so subtract the x-coordinates: 5 − (−3) = 8.

3. QuestionMultiple choice

Reflecting (4,−2)(4, −2) across the x-axis gives which point?

Please select an answer first.

Correct answer: C

The correct answer is (4,2)(4, 2).

  1. Identify the math idea: Decide whether the question uses linear relationships, numbers, expressions, equations, geometry, statistics, probability, or problem solving.
  2. Show the reasoning: A reflection across the x-axis keeps x and changes the sign of y.
  3. Check the result: Review the sign, units, operation, and estimate to make sure the answer is reasonable.

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

4. QuestionMultiple choice

A dilation uses a scale factor of 3. A side originally measures 4 units. What is the new side length?

Please select an answer first.

Correct answer: D

The correct answer is 12units12 units.

  1. Identify the math idea: Decide whether the question uses linear relationships, numbers, expressions, equations, geometry, statistics, probability, or problem solving.
  2. Show the reasoning: Multiply the original length by the scale factor: 4 × 3 = 12 units.
  3. Check the result: Review the sign, units, operation, and estimate to make sure the answer is reasonable.

Multiply the original length by the scale factor: 4 × 3 = 12 units.

5. QuestionMultiple choice

What is the volume of a cylinder with radius 3 units and height 5 units? Use ππ as the exact value.

Please select an answer first.

Correct answer: A

The correct answer is 45πcubicunits45π cubic units.

  1. Identify the math idea: Decide whether the question uses linear relationships, numbers, expressions, equations, geometry, statistics, probability, or problem solving.
  2. Show the reasoning: Use V = πr squared h: π × 3 squared × 5 = 45π cubic units.
  3. Check the result: Review the sign, units, operation, and estimate to make sure the answer is reasonable.

Use V = πr squared h: π × 3 squared × 5 = 45π cubic units.

6. QuestionMultiple choice

What is the volume of a cone with radius 3 units and height 4 units? Use ππ as the exact value.

Please select an answer first.

Correct answer: B

The correct answer is 12πcubicunits12π cubic units.

  1. Identify the math idea: Decide whether the question uses linear relationships, numbers, expressions, equations, geometry, statistics, probability, or problem solving.
