In the circle, the segment is a:
-
Radius.
-
Center.
-
Chord.
-
Diameter.
Correct Answer
A. Radius.Explanation
A segment in a circle is a part of the circle that is enclosed by a chord. A chord is a line segment that connects two points on the circumference of the circle. In this case, the segment mentioned in the question is not a chord because it does not connect two points on the circumference. Instead, it is a radius, which is a line segment that connects the center of the circle to any point on the circumference. Therefore, the correct answer is radius.Rate this question:

Which unit would you use to measure the water used to take a shower?
-
Gallon
-
Pint
-
Cup
-
Fluid ounce
Correct Answer
A. GallonExplanation
The gallon is the most appropriate unit to measure the water used to take a shower because it is a larger unit of volume compared to the other options. 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 and would not accurately represent the amount of water used in a shower.Rate this question:

-
94,426
-
95,403
-
95,430
-
95,490
Correct Answer
A. 95,430Explanation
The correct answer is 95,430. To find the sum of 23,816 and 71,614, we add the corresponding place values of each digit. Starting from the rightmost digit, 6+4 equals 10, so we write down 0 and carry over the 1 to the next column. In the next column, we have 1+1+1 equals 3. Then, in the next column, we have 8+6 equals 14, so we write down 4 and carry over the 1. Finally, in the leftmost column, we have 2+7+1 equals 10, so we write down 0 and carry over the 1. The sum is 95,430.Rate this question:

Which is the most reasonable estimate for 315 divided by 4?
-
8
-
9
-
80
-

Correct Answer
A. 80Explanation
To estimate 315 divided by 4, we can round 315 to the nearest multiple of 4, which is 316. Dividing 316 by 4 gives us 79 with a remainder of 0. Since 315 is slightly less than 316, the most reasonable estimate would be slightly less than 79, which is 80. Therefore, 80 is the most reasonable estimate for 315 divided by 4.Rate this question:

Find the perimeter of the rectangle.
-
14 m
-

-
28 m
-
48 m
Correct Answer
A. 28 mExplanation
The perimeter of a rectangle is calculated by adding up all the sides of the rectangle. In this case, the two sides given are 14 m and 20 m. To find the perimeter, we add these two sides together: 14 m + 20 m = 34 m. However, since the question asks for the perimeter, we need to double this value because a rectangle has two pairs of equal sides. Therefore, the perimeter of the rectangle is 2 * 34 m = 68 m. Since none of the given options match this answer, the correct answer is not available.Rate this question:

Correct Answer
A. 48 square metersExplanation
The area of a rectangle is calculated by multiplying its length by its width. Since the question does not provide any specific measurements for the length and width, we can assume that the length and width are both equal to 48 meters. Therefore, the area of the rectangle would be 48 meters multiplied by 48 meters, which equals 48 square meters.Rate this question:
