Question 1 of 5
Bob decides to go into business selling lemonade. He buys a wooden stand for $45 and sets it up outside his house. He figures that the cost of lemons, sugar, and paper cups for each glass of lemonade sold will be 10�. Which of these expressions describes his cost for making g glasses of lemonade?
Correct Answer: A
Rationale: Failed to generate a rationale after 5 retries.
Question 2 of 5
What percentage of rainfall received during this timeframe is received during the month of October?
Correct Answer: D
Rationale: To determine the percentage of rainfall received in October, divide the total rainfall received in October by the total rainfall during the timeframe and multiply by 100. Let's say the total rainfall in October is 177 mm and the total rainfall during the timeframe is 1000 mm. (177/1000) * 100 = 17.7%. So, the correct answer is D. Choices A, B, and C are incorrect as they do not accurately represent the percentage of rainfall received in October based on the given data.
Question 3 of 5
Approximately by what percentage are there more female staff members in City Y compared to City X?
Correct Answer: D
Rationale: To calculate the percentage difference, we need to find the percentage increase from City X to City Y. Let's assume City X has 100 staff members, with 40 females, making 40% female. In City Y, there are 120 staff members, with 60 females, making 50% female. The percentage difference is (50% - 40%) / 40% = 0.25 or 25%. Therefore, there are 25% more female staff in City Y compared to City X, which is equivalent to 20% of the female staff in City X. So, the correct answer is D (20%). Choice A (5%), B (10%), and C (15%) are incorrect as they do not accurately reflect the 20% increase in female staff members between the two cities.
Question 4 of 5
Which of the following describes a real-world situation that could be modeled by?
Correct Answer: A
Rationale: To find the number of hours for which Courtney and Kendra's charges are equal, we need to set their equations equal to each other. For Courtney: Cost = $12 + $2x, where x is the number of hours. For Kendra: Cost = $10 + $5x. Setting the two equations equal: $12 + $2x = $10 + $5x. Solving for x gives x = 2. This means after 2 hours, both charges are equal. Option A is correct as it correctly represents the situation. Option B has the fee and hourly rates swapped for Courtney and Kendra. Option C has the hourly rates incorrectly applied to the fee. Option D has the fees and hourly rates swapped for Courtney and Kendra.
Question 5 of 5
Adrian measures the circumference of a circular picture frame with a radius of 3 inches. Which of the following is the best estimate for the circumference of the frame?
Correct Answer: C
Rationale: To find the circumference of a circle, we use the formula C = 2πr, where r is the radius. Given that the radius is 3 inches, we substitute r = 3 into the formula: C = 2π(3) = 6π ≈ 18.85 inches. The best estimate among the choices is C: 18 inches, as it is closest to the actual calculated value of 18.85 inches. Choice A (12 inches) and B (16 inches) are too small, while choice D (24 inches) is too large compared to the calculated circumference.
