Correct Answer: A

Rationale: To find the width of the field, we need to set up the equation for the area of a rectangle: Area = length x width. Given that the area is 1452 square feet, and the length is three times the width, we can write the equation as 1452 = 3x * x. Solving for x (width), x = 18 feet. Therefore, the correct answer is A: 22 feet. Option B, 44 feet, is incorrect as it is double the correct width. Option C, 242 feet, is incorrect as it does not match the calculated width. Option D, 1452 feet, is incorrect as it represents the total area of the field, not the width.

Correct Answer: C

Rationale: To find the total potential savings, we first calculate the 20% discount on the car price: 20% of $26,580 = $5,316. Next, we calculate the total monthly payments saved: 3 payments x $250 = $750. Adding the discount and saved payments gives us a total potential savings of $5,316 + $750 = $6,066. Therefore, choice C is correct. Choice A is incorrect because it does not account for the monthly payments saved. Choice B is incorrect as it only considers the discount on the car price, ignoring the saved payments. Choice D is incorrect as it overestimates the savings by combining the discount and payments saved twice.

Correct Answer: A

Rationale: To find the diameter of a circle from its circumference, we use the formula: Diameter = Circumference / π. Given the circumference is 49 feet, we can calculate the diameter by dividing 49 by π (approximately 3.14), resulting in 15.6 feet, which is choice A. Option B, 17.8 feet, is incorrect as it does not match the calculation. Option C, 49 feet, is the circumference, not the diameter. Option D, 153.9 feet, is incorrect as it is not the result of dividing the circumference by π. Therefore, choice A is the correct answer based on the formula for finding the diameter of a circle.

Correct Answer: D

Rationale: To convert a decimal to a fraction, we count the number of decimal places and put the digits after the decimal over the appropriate power of 10. For 3.28, there are two decimal places, so we write it as 328/100. Simplifying gives us 41/25, which matches choice D. Choices A, B, and C are incorrect as they do not represent the value of 3.28 when converted to a fraction. Option A is equivalent to 3.28 written as 3.28/1, which is not correct. Options B and C do not represent 3.28 accurately either.

Correct Answer: C

Rationale: To determine the correct order from least to greatest, convert all fractions to decimals: - (1/7) = 0.142857 - 0.125 - (6/9) = 0.666666 - 0.60 The correct order is 0.125, (1/7), 0.60, (6/9) because 0.125 is the smallest, followed by (1/7), then 0.60, and finally (6/9) which is equivalent to 0.666666. Other choices are incorrect because they do not follow the increasing order of magnitude. Choice A has the fractions in a different order, choice B has 0.60 in the wrong position, and choice D has the fractions in the wrong order. Therefore, choice C is the correct answer.
