Explanation
The area of a triangle is calculated by multiplying the base by the height and dividing the result by 2. In this case, the base is 6 inches and the height is 5 inches. So, the area of the triangle is (6 * 5) / 2 = 15 square inches.

Explanation
The average of a set of numbers is found by adding up all the numbers and then dividing the sum by the total number of values. In this case, the sum of 102, 100, 96, and 90 is 388. Dividing 388 by 4 (the total number of values) gives us an average of 97.

Explanation
The expression (7 + 2) + 9 is solved by first adding 7 and 2, which gives 9. Then, adding 9 to 9 results in 18. Therefore, the correct answer is 18.

Explanation
The given question asks for the lowest terms of 48/100. The answer "25-Dec" does not make sense in this context and is likely a mistake. It is possible that the person who wrote the answer accidentally typed "25-Dec" instead of the correct answer. Without further information, it is not possible to determine the correct explanation for this answer.

Explanation
The given expression is 7 + (2 x 2). According to the order of operations, we should first perform the multiplication, which gives us 4. Then, we add 7 to 4, resulting in 11. Therefore, the correct answer is 11.

Explanation
The number 3.5 is the only option that falls between 3 and 4. It is greater than 3 but less than 4. The other options, 5, 2.9, and 4.1, are either greater than 4 or less than 3 and therefore do not fit the criteria.

Explanation
The given question asks for the sum of 1/4 and 5/8. To find the sum, we need to have a common denominator. The common denominator of 4 and 8 is 8. We can convert 1/4 to 2/8. Now we can add 2/8 and 5/8, which equals 7/8. Therefore, the answer is 7/8, which is equivalent to 8-Jul.

Explanation
The number to the right of 7 on the number line is 8.

Explanation
The correct answer is 6-May because when you add 2/3 and 1/6, you need to find a common denominator, which is 6. Then, you add the numerators together, resulting in 3/6. This fraction can be simplified to 1/2. Therefore, 2/3 + 1/6 equals 1/2, which can be represented as 6-May on a calendar.

Explanation
The perimeter of a triangle is the sum of the lengths of its sides. In this case, each side of the triangle is 4 inches long. Therefore, the perimeter of the triangle is 4 + 4 + 4 = 12 inches.

Explanation
The number 7.4 is the largest among the given options because it has the highest whole number value. The other numbers, 0.47, 4.7, and 0.74, are all smaller than 7.4 when comparing their whole number values.

Explanation
If a box of 25 identical books weighs 50 pounds, it means that each book weighs 2 pounds. This can be determined by dividing the total weight of the books (50 pounds) by the number of books in the box (25 books), which gives us 2 pounds per book.

Explanation
There are 60 minutes in one hour. Therefore, to find the number of minutes in two hours, we multiply 60 by 2, which equals 120.

Explanation
A football field is typically 100 yards long. Since there are 3 feet in a yard, the length of the football field in feet would be 100 yards multiplied by 3 feet per yard, which equals 300 feet. Therefore, the correct answer is 300.
