Question 1 of 5
A large pizza has a diameter of 9 inches. Which of the following is the area of the pizza in terms of pi?
Correct Answer: D
Rationale: To find the area of a circle, we use the formula A = πr², where r is the radius of the circle. In this case, the diameter is 9 inches, so the radius is half of the diameter, which is 4.5 inches. Substituting the radius into the formula, we get A = π(4.5)² = 20.25 πin². Therefore, the correct answer is 20.25 πin². Choices A, B, and C are incorrect because they do not correctly calculate the area using the radius of the circle.
Question 2 of 5
If a box of 55 syringes costs $660.00, what is the cost of four syringes?
Correct Answer: D
Rationale: In this math problem, we are asked to find the cost of four syringes given that a box of 55 syringes costs $660. To solve this problem, we need to set up a proportion based on the relationship between the number of syringes and their cost. If 55 syringes cost $660, then we can set up the proportion: 55 syringes / $660 = 4 syringes / x Cross multiplying, we get: 55 * x = 4 * $660 x = (4 * $660) / 55 x = $48 Therefore, the correct answer is D) $48. Explanation for why the other options are incorrect: - Option A) $51 is incorrect because it is not proportional to the cost of 4 syringes compared to 55 syringes. - Option B) $26 is incorrect because it is too low for the cost of 4 syringes based on the given information. - Option C) $32 is incorrect because it does not align with the proportionality between the number of syringes and their cost in this scenario. Educational context: This question assesses the student's understanding of proportions and how to apply them in real-world scenarios involving cost and quantity relationships. It reinforces the importance of setting up and solving proportions accurately to find unknown values in similar situations. Understanding this concept is crucial for success in math and practical applications in various fields.
Question 3 of 5
What is the equivalent weight in pounds for 45 kg? (1 kg = 2.2 lbs)
Correct Answer: C
Rationale: To convert kilograms to pounds, multiply the weight in kilograms by the conversion factor 2.2 (1 kg = 2.2 lbs). Therefore, 45 kg * 2.2 lbs/kg = 99 lbs. Choice A is incorrect because it is a miscalculation. Choice B is incorrect as it does not reflect the correct conversion. Choice D is incorrect as it is also a miscalculation of the conversion.
Question 4 of 5
The graph below represents the amount of rainfall in a particular state by month. What is the total rainfall for the months May, June, and July?
Correct Answer: A
Rationale: To calculate the total rainfall for May, June, and July, we add the rainfall amounts for each month: 3.2 inches (May) + 2.5 inches (June) + 3.3 inches (July) = 9.0 inches. Therefore, the correct answer is A. Choice B (8.4 inches) is incorrect as it does not account for the correct sum of rainfall for the specified months. Choice C (7.5 inches) is incorrect as it does not include the accurate total rainfall for May, June, and July. Choice D (10.5 inches) is incorrect as it provides a total that exceeds the actual combined rainfall for the given months.
Question 5 of 5
What is the mathematical expression for 'Twelve less than thrice a number'?
Correct Answer: A
Rationale: The phrase 'thrice a number' translates to 3x, and 'twelve less than' means subtracting 12 from it. Therefore, the correct expression is 3x-12. Choice B, '12-3x', represents '12 less than a number thrice,' which is the opposite of the given phrase. Choice C, '3-12x', does not correctly interpret the phrase provided. Choice D, '12x-3', represents 'a number thrice less than twelve,' which is not the same as the original phrase.
