Please select an answer first.

Correct answer: B

The correct answer is 65 degrees.

  1. Read the problem: Identify the quantities, operation, relationship, expression, or geometric information in the problem.
  2. Show the strategy: Triangle angles total 180, and 180 minus 48 minus 67 equals 65.
  3. Check the result: Make sure the answer matches the units and the context of the Delaware Grade 7 DeSSA Math task.

Triangle angles total 180, and 180 minus 48 minus 67 equals 65.

3. QuestionMultiple choice

A rectangular prism has dimensions 8, 2.5, and 4 units. What is its volume?

Please select an answer first.

Correct answer: C

The correct answer is 80 cubic units.

  1. Read the problem: Identify the quantities, operation, relationship, expression, or geometric information in the problem.
  2. Show the strategy: Multiplying 8 times 2.5 times 4 gives 80 cubic units.
  3. Check the result: Make sure the answer matches the units and the context of the Delaware Grade 7 DeSSA Math task.

Multiplying 8 times 2.5 times 4 gives 80 cubic units.

4. QuestionMultiple choice

A data set is 6, 8, 8, 10, 13. What is the mean?

Please select an answer first.

Correct answer: D

The correct answer is 9.

  1. Read the problem: Identify the quantities, operation, relationship, expression, or geometric information in the problem.
  2. Show the strategy: The sum is 45, and 45 divided by 5 equals 9.
  3. Check the result: Make sure the answer matches the units and the context of the Delaware Grade 7 DeSSA Math task.

The sum is 45, and 45 divided by 5 equals 9.

5. QuestionMultiple choice

A data set is 4, 9, 12, 15, 18, 21. What is the interquartile range if Q1 is 9 and Q3 is 18?

Please select an answer first.

Correct answer: A

The correct answer is 9.

  1. Read the problem: Identify the quantities, operation, relationship, expression, or geometric information in the problem.
  2. Show the strategy: The interquartile range is Q3 minus Q1: 18 minus 9 equals 9.
  3. Check the result: Make sure the answer matches the units and the context of the Delaware Grade 7 DeSSA Math task.

The interquartile range is Q3 minus Q1: 18 minus 9 equals 9.

6. QuestionMultiple choice

Two angles are supplementary. One measures 118 degrees. What is the other?

Please select an answer first.

Correct answer: B

The correct answer is 62 degrees.

  1. Read the problem: Identify the quantities, operation, relationship, expression, or geometric information in the problem.
  2. Show the strategy: Supplementary angles total 180, and 180 minus 118 equals 62.
  3. Check the result: Make sure the answer matches the units and the context of the Delaware Grade 7 DeSSA Math task.

Supplementary angles total 180, and 180 minus 118 equals 62.

7. QuestionMultiple choice
