convert 58 to a decimal

HESI A2

Math HESI A2 Practice Test

1. Convert 5/8 to a decimal.

A. 0.625
B. 0.5
C. 0.4
D. 0.75

Correct answer: A

Rationale: To convert 5/8 to a decimal, divide 5 by 8: 5 ÷ 8 = 0.625. The correct answer is A (0.625). Choice B (0.5) is incorrect because it represents 1/2. Choice C (0.4) is incorrect because it represents 2/5. Choice D (0.75) is incorrect because it represents 3/4.

2. Select the phrase or clause that is misplaced in the following sentence: At a presentation, he informed us about the dangers of drugs and alcohol in the auditorium.

A. At a presentation
B. about the dangers
C. of drugs and alcohol
D. in the auditorium

Correct answer: D

Rationale: The phrase 'in the auditorium' is misplaced in the sentence because it suggests that the dangers of drugs and alcohol were in the auditorium, which is not the intended meaning. It would make more sense for this phrase to come immediately after 'he informed us' to indicate where the presentation took place. Choices A, B, and C are all correctly placed within the sentence, providing necessary information about the context and topic of the presentation.

3. What is the result of multiplying 8 by 2?

A. 16
B. 22
C. 24
D. 32

Correct answer: A

Rationale: The correct answer is A: 16. When you multiply 8 by 2, the result is 16. Choice B (22), Choice C (24), and Choice D (32) are incorrect as they do not represent the correct multiplication of 8 by 2.

4. Which word is not spelled correctly in the context of the following sentence? The pharmacist seemed to disagree with the prescription designated by the physician.

A. pharmacist
B. prescription
C. designated
D. physician

Correct answer: B

Rationale: The word 'prescription' in the sentence is misspelled as 'proscription.' A prescription is a written order for medication or treatment provided by a healthcare professional, while a proscription means a forbidding or prohibition. The other choices (A, C, D) are all correctly spelled in the context of the sentence.

5. For the core of an electromagnet, a material with high:

A. Resistivity is ideal
B. Permeability is preferred
C. Permittivity is crucial
D. Dielectric strength is essential

Correct answer: B

Rationale: A material with high permeability is preferred for the core of an electromagnet because it allows magnetic field lines to pass through it easily, enhancing the strength of the magnetic field generated. Choice A is incorrect because high resistivity would impede the flow of current in the coil, reducing the strength of the magnetic field. Choice C is incorrect as permittivity is related to electric fields, not magnetic fields. Choice D is also incorrect because dielectric strength is about insulating materials against breakdown under an electric field, not relevant to enhancing magnetic fields.
