7. Multiple-choice questions: These questions provide you with several answer choices, and you must select the correct one.
8. Numeric entry questions: These questions require you to enter a numeric value as the answer rather than selecting from answer choices.
B. Use multiple approaches
1. Apply formulas and equations
- Identify the given information: Before applying any formula or equation, read the question carefully and identify the given information. This will help you determine which formula or equation to use.
- Understand the formula or equation: Make sure you understand the formula or equation you are using. If you are unsure, review the formula or equation and its components.
- Substitute values: Once you have identified the formula or equation to use, substitute the given values into the appropriate variables.
- Simplify: Simplify the equation or formula as much as possible to make it easier to solve.
- Solve for the unknown: Use algebraic manipulation to solve for the unknown variable. Make sure to follow the order of operations and simplify as you go.
- Check your answer: Always check your answer to make sure it makes sense in the context of the problem.
2. Use estimation and approximation
1. A rectangular room is 15 feet long, 10 feet wide, and 8 feet high. What is the approximate volume of the room in cubic feet?
To estimate the volume, we can round the dimensions to the nearest whole number: Length = 15 feet ≈ 15 feet Width = 10 feet ≈ 10 feet Height = 8 feet ≈ 8 feet
Then, we can multiply the rounded dimensions to get an approximate volume: Volume ≈ 15 feet × 10 feet × 8 feet Volume ≈ 1,200 cubic feet
Therefore, the approximate volume of the room is 1,200 cubic feet.
2. A store is having a sale where all items are 25% off. If a shirt originally costs $40, what is the approximate sale price of the shirt?
To estimate the sale price, we can round the original price to the nearest ten: Original price = $40 ≈ $40
Then, we can subtract 25% of the rounded price to get an approximate sale price: Sale price ≈ $40 – 25% of $40 Sale price ≈ $40 – $10 Sale price ≈ $30
Therefore, the approximate sale price of the shirt is $30.
3. A train travels 300 miles in 5 hours. What is the approximate speed of the train in miles per hour?
To estimate the speed, we can round the distance and time to the nearest hundred: Distance = 300 miles ≈ 300 miles Time = 5 hours ≈ 5 hours
Then, we can divide the rounded distance by the rounded time to get an approximate speed: Speed ≈ 300 miles ÷ 5 hours Speed ≈ 60 miles per hour
Therefore, the approximate speed of the train is 60 miles per hour.
