HESI A2 Math Questions
Question 1 of 5
Square: A garden bed has a side length of 8 meters. What is its perimeter?
Correct Answer: C
Rationale: The perimeter of a square is found by adding up all four sides. Since all sides of a square are equal in length, the perimeter is calculated by multiplying the side length by 4. In this case, the side length of the square garden bed is 8 meters.
Therefore, the perimeter is 8m x 4 = 32m.
Choice A (16m) is incorrect as it represents only half of the perimeter.
Choice B (24m) is incorrect because it is the perimeter of a square with a side length of 6 meters, not 8 meters.
Choice D (64m) is incorrect as it represents the area of the square, not the perimeter.
Question 2 of 5
An artist sells paintings at $5.50 each. She has 7 stands and pays $35 per stand. What is her profit if she sells an average of 11 paintings per stand?
Correct Answer: B
Rationale:
To calculate the profit, first determine the total revenue: 7 stands * 11 paintings per stand * $5.50 per painting = $423.50.
Then, subtract the total stand expenses ($35 per stand * 7 stands = $245) from the total revenue to get the profit: $423.50 - $245 = $178.50.
Therefore, the correct answer is $178.50. Option A is incorrect because it does not account for the stand expenses. Option C is incorrect as it does not consider the total revenue. Option D is incorrect as it overestimates the profit by not deducting the stand expenses.
Question 3 of 5
A marathon runner completes 21.4 miles and burns 2276 calories. What is her rate of calories burned per mile?
Correct Answer: B
Rationale:
To find the rate of calories burned per mile, divide the total calories burned by the total miles run. In this case, 2276 calories · 21.4 miles = 106.4 calories per mile.
Therefore, the correct answer is B.
Choice A (106.3) is incorrect because it is slightly lower than the calculated value.
Choice C (106.355) is incorrect as it is a more precise value than the calculation result.
Choice D (106.36) is also incorrect as it is a more precise value than the calculated answer.
Question 4 of 5
A nurse works in a neonatal unit where infants' weights are measured in grams. What is the equivalent of 1,500 grams in pounds?
Correct Answer: A
Rationale:
To convert grams to pounds, you can use the conversion factor: 1 pound = 453.59237 grams.
Therefore, to find the equivalent of 1,500 grams in pounds, divide 1,500 by 453.59237 to get approximately 3.3 pounds.
Choice A is the correct answer because it accurately represents the conversion.
Choices B, C, and D are duplicates and do not provide an alternative option.
Question 5 of 5
If Mr. Parker owns 150 shares of stock in Stark Industries and receives $180.00 per year in dividends, how much does Mr. Rogers receive for an annual dividend if he owns 400 shares?
Correct Answer: A
Rationale:
To find out how much Mr. Rogers receives for an annual dividend with 400 shares, we can set up a proportion: 400 shares is to X dollars as 150 shares is to $180. This gives us 400 * $180 / 150 = $480 in annual dividends.
Therefore, the correct answer is A.
Choice B, $500, is incorrect because it does not consider the proportionality of shares to dividend amount.
Choice C, $450, is incorrect as it does not reflect the correct calculation based on the given information.
Choice D, $72,000, is significantly higher and incorrect as it does not align with the proportionality of shares and dividends.
