Which unit would you use to measure the water used to take a shower?
- A.
Gallon
- B.
Pint
- C.
Cup
- D.
Fluid ounce
Correct Answer
A. GallonExplanation
The gallon is the appropriate unit to measure the water used to take a shower because it is a larger unit of measurement compared to pint, cup, and fluid ounce. Showers typically use a significant amount of water, and gallons are commonly used to measure larger quantities of liquid. Pints, cups, and fluid ounces are smaller units of measurement that would not accurately represent the amount of water used during a shower.Rate this question:

5,000
- B.
8,000
- C.
50,000
- D.
80,000
Correct Answer
A. 5,000Explanation
The most reasonable estimate for 12 x 472 is 5,000 because when multiplying 12 by 472, we can round both numbers to the nearest hundred. 12 is close to 0 and 472 is close to 500. When we multiply these rounded numbers (0 x 500), we get 0. Therefore, the product of 12 x 472 is likely to be closer to 0 than any of the other given options.Rate this question:

- A.
94,426
- B.
95,403
- C.
95,430
- D.
95,490
Correct Answer
C. 95,430Explanation
To find the sum of 23,816 and 71,614, we add the corresponding digits in each place value. Starting from the rightmost place value, 6 + 4 equals 10, so we carry over the 1 to the next place value. In the next place value, we have 1 + 1 + 1 (carried over) which equals 3. Continuing this process, we get 3 + 6 + 7 + 1 = 17 in the thousands place. Lastly, we add the 1 in the ten thousands place. Therefore, the sum is 95,430.Rate this question:

C. 28 mExplanation
The perimeter of a rectangle is found by adding up the lengths of all its sides. In this case, the given sides are 14 m and 20 m. Adding these two sides together gives a total of 34 m. However, since the question asks for the perimeter, we need to double this value to account for both the length and width of the rectangle. Therefore, the correct answer is 28 m.Rate this question:
