Mathematics Practice Test for the HESI® exam

Question 1

A survey firm must make phone calls to 136 people. To make the 136 long-distance calls, how many buttons must be pressed?

Accepted Answer

1360

Answer

This question assumes a standard number of buttons pressed for each long-distance phone call. If each call requires 10 button presses (e.g., '1' + area code + 7-digit number), then for 136 calls, the total number of button presses would be 136 calls * 10 buttons/call, which equals 1360 buttons.

Question 2

1 liter contains how many milliliters?

Accepted Answer

1000

Answer

The metric system is based on powers of 10 for unit conversions. A milliliter (mL) is defined as one-thousandth of a liter (L). Therefore, there are exactly 1000 milliliters in 1 liter.

Question 3

Each pound has 453.59 grams. 6,577 grams is the weight of a baby. In pounds and ounces, how much does the baby weigh?

Accepted Answer

14 lb 8 oz.

Answer

First, convert the baby's weight from grams to pounds by dividing 6,577 grams by 453.59 grams/pound, which yields approximately 14.5 pounds. Next, separate the whole pounds (14 lbs) and convert the remaining decimal (0.5 lbs) into ounces by multiplying by 16 ounces/pound (0.5 * 16 = 8 ounces). Thus, the baby weighs 14 pounds and 8 ounces.

Question 4

The waist circumference of a man is 88.9 centimeters. What is his waist measurement in inches?

Accepted Answer

35 in.

Answer

To convert a measurement from centimeters to inches, you divide the centimeter value by the conversion factor of 2.54 centimeters per inch. Therefore, 88.9 cm divided by 2.54 cm/inch equals exactly 35 inches.

Question 5

In Celsius, what are 98.6 degrees Fahrenheit?

Accepted Answer

37 degrees Celsius

Answer

To convert degrees Fahrenheit to Celsius, use the formula C = (F - 32) * 5/9. Substituting 98.6 degrees Fahrenheit, the calculation is (98.6 - 32) * 5/9 = 66.6 * 5/9 = 37 degrees Celsius. This is the standard normal human body temperature.
