HESI A2 Math Practice Test 2024

Correct Answer: A

Rationale: To find how much the student earned for working 6 hours, we can use the formula: Earnings = (Total pay / Total hours) x Hours worked. In this case, Earnings = ($120 / 10 hours) x 6 hours = $72. Therefore, the correct answer is A: $72. Choice B, $90, is incorrect as it does not match the calculated amount. Choice C, $80, is also incorrect. Choice D, $50, is incorrect because it is too low based on the calculated earnings for 6 hours.

Correct Answer: A

Rationale: To convert kilograms to grams, you need to multiply by 1000 as there are 1000 grams in 1 kilogram. Therefore, to find the number of grams in 4 kilograms, you would multiply 4 by 1000, which equals 4000 grams. So, the correct answer is A: 4000. Choice B (40) would be the result if you mistakenly multiplied by 10 instead of 1000. Choice C (500) is the result if you mistakenly added or subtracted a zero. Choice D (0) is clearly incorrect as there are grams in 4 kilograms.

Correct Answer: A

Rationale: To calculate the total number of patients monitored, we add the number of patients each nurse monitored: 6 + 8 + 12 = 26 patients. Therefore, the correct answer is A (26 patients). Nurse 1 monitored 6 patients, Nurse 2 monitored 8 patients, and Nurse 3 monitored 12 patients, totaling 26 patients. Choices B, C, and D are incorrect because they do not accurately represent the sum of patients monitored by all three nurses.

Correct Answer: A

Rationale: To find how much the student earned for working 6 hours, we can use the formula: Earnings = (Total pay / Total hours) x Hours worked. In this case, Earnings = ($120 / 10 hours) x 6 hours = $72. Therefore, the correct answer is A: $72. Choice B, $90, is incorrect as it does not match the calculated amount. Choice C, $80, is also incorrect. Choice D, $50, is incorrect because it is too low based on the calculated earnings for 6 hours.

Correct Answer: C

Rationale: To convert scientific notation (4.82 x 10^3) to standard form, we multiply the coefficient (4.82) by 10 raised to the exponent (3). This gives us 4.82 x 1000 = 4820. Therefore, the value of the number in standard form is 4820. Explanation of incorrect choices: A: 0.00482 - This choice is incorrect because it represents a smaller value than the original number. B: 0.482 - This choice is incorrect as it is also smaller than the original number. D: 4820000 - This choice is incorrect as it represents a larger value than the original number.
