Question 1 of 5
There are 6,657 marbles in a jar. Approximately 34% are white, and the rest are black. How many black marbles are there?
Correct Answer: A
Rationale:
To find the number of black marbles, we need to calculate the percentage that represents the black marbles, which is 100% - 34% = 66%.
Then, we find 66% of 6,657 to determine the number of black marbles. 66% of 6,657 is approximately 4,394, so there are 4,394 black marbles in the jar.
Choice A is correct.
Choices B, C, and D are incorrect as they do not reflect the correct calculation for the number of black marbles in the jar.
Question 2 of 5
Add: 1.332 + 0.067
Correct Answer: A
Rationale:
To find the sum of 1.332 and 0.067, add the two numbers correctly: 1.332 + 0.067 = 1.399.
Therefore, the correct answer is A.
Choice B (1.4) is incorrect because it rounds down the sum, not considering the precise value.
Choice C (1.402) is incorrect as it results from adding 1.332 and 0.070 instead of 0.067.
Choice D (1.5) is not the correct sum of the given numbers.
Question 3 of 5
A nurse working at a medical clinic earns $17.81 per hour. The nurse works three 8-hour shifts and one 12-hour shift every week and is paid weekly. Weekly deductions include federal tax $102.80, state tax $24.58, federal insurance $18.13, and family health insurance $52.15. What is the nurse's take-home pay each week?
Correct Answer: A
Rationale:
To calculate the nurse's take-home pay, first determine the weekly gross income. The nurse works 3 shifts x 8 hours = 24 hours at $17.81 per hour plus 1 shift x 12 hours = 12 hours at $17.81 per hour, totaling 36 hours.
Therefore, the gross income is 36 hours x $17.81 = $641.16. Next, subtract the weekly deductions: federal tax $102.80 + state tax $24.58 + federal insurance $18.13 + family health insurance $52.15 = $197.66. Deducting $197.66 from the gross income gives $641.16 - $197.66 = $443.50 as the nurse's take-home pay each week.
Therefore, the correct answer is $443.50.
Choice B ($450.00) is incorrect because it does not consider the specific deductions provided.
Choices C ($500.00) and D ($430.00) are also incorrect as they do not reflect the accurate calculation based on the given information.
Question 4 of 5
Convert 5 3/4 to a decimal. Round to the nearest tenth.
Correct Answer: C
Rationale:
To convert 5 3/4 to a decimal, we add the whole number part to the fractional part: 5 + 3/4 = 5.75. Rounding 5.75 to the nearest tenth gives us 5.8.
Therefore, the correct answer is C.
Choice A (5.6) is incorrect because it does not accurately represent 5 3/4.
Choice B (5.7) is incorrect as well because it does not reflect the correct conversion.
Choice D (6) is incorrect as it does not account for the fractional part of 5 3/4.
Question 5 of 5
Jan canned 5 gallons of homemade tomatoes. She needs to purchase quart jars to finish the process. How many quart jars will she need to buy for her tomatoes?
Correct Answer: C
Rationale:
To determine the number of quart jars needed, we first need to convert the gallons to quarts. Since 1 gallon equals 4 quarts, 5 gallons will be equal to 5 * 4 = 20 quarts.
Therefore, Jan will need to buy 20 quart jars to store her canned tomatoes.
Choices A, B, and D are incorrect as they do not correctly convert the gallons to quarts, leading to an incorrect quantity of jars required.
