Kendra wanted to take a bubble bath. What is a reasonable estimate for the capacity of her bathtub?
- A.
20 cups
- B.
2 quarts
- C.
2 gallons
- D.
20 gallons
Correct Answer
D. 20 gallonsExplanation
A reasonable estimate for the capacity of Kendra's bathtub is 20 gallons. This is because a bubble bath typically requires a larger amount of water compared to regular bathing. Cups and quarts are too small to hold enough water for a bubble bath, and 2 gallons may not be enough to fill the entire bathtub. Therefore, 20 gallons is a reasonable estimate for the capacity of her bathtub.Rate this question:

Which unit of measurement is the most reasonable to measure the length of Dalton's hamster?
- A.
Inches (in)
- B.
Feet (ft)
- C.
Yards (yd)
- D.
Miles (mi)
Correct Answer
A. Inches (in)Explanation
The most reasonable unit of measurement to measure the length of Dalton's hamster is inches (in) because hamsters are small animals and their length is typically measured in smaller units. Feet, yards, and miles are larger units of measurement that would not be suitable for measuring the length of a hamster accurately.Rate this question:

B. 20 mmExplanation
A quarter is a coin that is commonly used in the United States, and it is known to have a small diameter. Among the given options, 20 mm is the most reasonable estimate for the diameter of a quarter. The other options, 0.20 mm, 200 mm, and 20 cm, are either too small or too large for the diameter of a quarter.Rate this question:

Estimate the length of a new, unsharpened pencil
- A.
18 mm
- B.
8 cm
- C.
18 cm
- D.
8 m
Correct Answer
C. 18 cmExplanation
The correct answer is 18 cm because it is a reasonable estimate for the length of a new, unsharpened pencil. Pencils are typically around 15-20 cm long, and since this is an unsharpened pencil, it would be closer to the longer end of that range. The other options (18 mm, 8 cm, and 8 m) are either too small or too large to be a realistic estimate for a pencil length.Rate this question:

Kevin is baking a cake for his math class. The recipe calls for 40 milliliters of water for every 20 milliliters of cooking oil. How many mililiters of water are needed if 50 milliliters of cooking oil were used?
- A.
25 ml
- B.
100 ml
- C.
200 ml
- D.
1,000 ml
Correct Answer
B. 100 mlExplanation
The recipe states that for every 20 milliliters of cooking oil, 40 milliliters of water are needed. If 50 milliliters of cooking oil were used, we can calculate the amount of water needed by setting up a proportion. Since 20 milliliters of cooking oil corresponds to 40 milliliters of water, we can set up the proportion 20/40 = 50/x, where x represents the amount of water needed. Solving for x, we find that x = 100. Therefore, 100 milliliters of water are needed if 50 milliliters of cooking oil were used.Rate this question:

Choose the correct conversion of 42 grams to milligrams.
- A.
0.042
- B.
0.42
- C.
420
- D.
42,000
Correct Answer
D. 42,000Explanation
The correct conversion of 42 grams to milligrams is 42,000. This is because there are 1,000 milligrams in 1 gram, so to convert grams to milligrams, you multiply the number of grams by 1,000. In this case, 42 grams multiplied by 1,000 equals 42,000 milligrams.Rate this question:
