Correct Answer: C

Rationale: Rationale: 1. To convert Fahrenheit to Celsius, you can use the formula: �C = (�F - 32) x 5/9. 2. Given that the patient's body temperature is 102�F, we can calculate the equivalent temperature in Celsius: �C = (102 - 32) x 5/9 �C = 70 x 5/9 �C = 350/9 �C ≈ 38.9�C, which can be rounded to 39�C. 3. A body temperature of 39�C is considered to indicate a fever. Normal body temperature typically ranges from 36.1�C to 37.2�C, so a temperature of 39�C is higher than the normal range and suggests a fever. 4. Options A and B are incorrect as they do not reflect the conversion of 102�F to �C

Correct Answer: C

Rationale: To divide 11 by 5, you need to perform the division operation. 11 divided by 5 equals 2.2. Therefore, the correct answer is C. Choice A (1.424) and Choice B (1.622) are incorrect as they do not result from the division of 11 by 5. Choice D (2) is close but not accurate, as the exact result of 11 divided by 5 is 2.2.

Correct Answer: C

Rationale: To convert Fahrenheit to Celsius, you can use the formula:

Correct Answer: C

Rationale: If two blank CDs cost 36 cents, each blank CD costs 18 cents (36 cents / 2). To find the cost of 10 blank CDs, you multiply the cost of one CD by the total number of CDs: 18 cents x 10 = $1.80. Therefore, it would cost $1.80 to buy 10 blank CDs. Choice A ($0.90) is incorrect because it miscalculates the cost per CD. Choice B ($1.35) is incorrect as it doesn't consider the total number of CDs. Choice D ($3.60) is incorrect as it miscalculates the cost of one CD.

Correct Answer: D

Rationale: To convert meters to feet, you can use the conversion factor: 1 meter = 3.28084 feet. Therefore, for 6 meters: 6 3.28084 = 19.684 feet. Rounding to two decimal places, the answer is 19.68 feet. Choice D, 19.68 feet, is the correct conversion. Choice A, 1.83 feet, is incorrect as it seems to be a miscalculation. Choice B, 18.48 feet, is incorrect as it doesn't match the correct conversion. Choice C, 18.8 feet, is also incorrect as it is not the accurate conversion from 6 meters to feet.
