HESI A2 Quizlet Math Questions
Question 1 of 5
If you have 4 kilograms, how many grams would you have?
Correct Answer: B
Rationale: To convert kilograms to grams, you need to multiply by 1000 since 1 kilogram is equal to 1000 grams. So, 4 kilograms x 1000 = 4000 grams. The correct answer is B. Choice A is incorrect as it only represents 1/10th of the correct value. Choice C is way too low and represents 1/100th of the correct value. Choice D is also significantly lower than the correct value.
Question 2 of 5
The price dropped from $200 to $150. By what percentage did the price decrease?
Correct Answer: D
Rationale: To calculate the percentage decrease, we use the formula: (Original Price - New Price) / Original Price * 100%. In this case, it would be (200 - 150) / 200 * 100% = 50 / 200 * 100% = 25%. Therefore, the correct answer is D (25%). Option A (5%), B (10%), and C (20%) are incorrect as they do not accurately represent the 25% decrease in price.
Question 3 of 5
What is the result of multiplying 10 by 5?
Correct Answer: B
Rationale: To find the result of multiplying 10 by 5, we simply perform the operation 10 x 5, which equals 50. This is because multiplication is a repeated addition, so 10 multiplied by 5 is the same as adding 10 together 5 times. Therefore, the correct answer is B. Choice A (65) is incorrect as it is the result of adding 10 and 5, not multiplying. Choice C (45) and D (55) are incorrect as they are not the result of multiplying 10 by 5.
Question 4 of 5
A farmer wants to plant trees around the outside boundaries of his rectangular field with dimensions of 650 meters 780 meters. Each tree requires 5 meters of free space all around it from the stem. How many trees can he plant?
Correct Answer: C
Rationale: To calculate the number of trees, we need to determine the area available for planting trees after considering the space each tree requires. The total area of the rectangular field is 650m * 780m = 507,000 sq. meters. Each tree requires a space of (5+5) meters horizontally and (5+5) meters vertically around it, totaling 10m * 10m = 100 sq. meters per tree. Therefore, the area needed for each tree is 100 sq. meters. To find the number of trees that can be planted, we divide the total area of the field by the area needed for each tree: 507,000 sq. meters / 100 sq. meters per tree = 5070 trees. However, since the space around the boundary cannot accommodate a full tree, we have to deduct the trees that cannot be planted along the boundary. The number of trees that cannot be planted along the length of the field = 780m /
Question 5 of 5
What number is represented by the Roman Numerals XLIV?
Correct Answer: C
Rationale: The Roman numeral XLIV represents the number 44. Here's the breakdown: - "XL" is 40 in Roman numerals. - Adding "IV" (4) to XL gives us 44. Therefore, the correct answer is C. Other choices are incorrect because: - A (34): This is incorrect as XL is 40, not 30. - B (54): XL is 40, not 50. - D (24): XL is 40, not 20.
