The number of radians in a 720-degree angle can be written as aπ, where a is a constant. What is the value of a?
Correct answer: B. 4
- A. 3
- B. 4
- C. 5
- D. 6
Explanation
The correct answer is 4. To convert degrees to radians, use the formula: Radians = Degrees × (π/180). For a 720-degree angle, the calculation is: 720 × (π/180) = 4π. Thus, the value of a is 4. Option A (3) represents 540 degrees, Option C (5) represents 900 degrees, and Option D (6) represents 1080 degrees.

About Quantitative Reasoning
Quantitative reasoning applies arithmetic and basic algebra to numerical relationships, including percentages, ratios, averages, fractions, proportions, profit and loss, rates, time, work and measurement. Questions focus on translating words into equations, choosing an efficient method and checking whether the result is numerically reasonable.

A shipping service restricts the dimensions of the boxes it will ship for a certain type of service. The restriction states that for boxes shaped like rectangular prisms, the sum of the perimeter of the base of the box and the height of the box cannot exceed 130 inches. The perimeter of the base is determined using the width and length of the box. If a box has a height of 60 inches and its length is 2.5 times the width, which inequality shows the allowable width x, in inches, of the box?
