To solve the given expression, we need to follow the order of operations (also known as PEMDAS/BODMAS). First, we divide 3 by 3, which equals 1. Then, we add 23 and 1, which gives us the final result of 24. Therefore, the correct answer is 24.

Multiplying 8 by 7 equals 56. Multiplication is the process of repeated addition, and 8 added to itself 7 times results in 56.

The square root of a number is a value that, when multiplied by itself, equals the original number. In this case, the square root of 144 is 12 because 12 × 12 = 144.

A century consists of 100 years. Since there are 12 months in a year, to calculate the number of months in a century, we multiply 100 by 12. Therefore, there are 1200 months in a century.

The next prime number after 7 is 11. Prime numbers are numbers that are only divisible by 1 and themselves, and 11 fits this criteria.

The area of a rectangle is calculated by multiplying its length by its width. In this case, the area is 8 units × 5 units = 40 square units.

The product of any number multiplied by zero is always zero. Therefore, when multiplying 131, 0, 300, and 4 together, the result will be zero.

By waiting to buy 12 pounds of peaches in June, the pie maker can save $0.50 per pound. Therefore, the total amount saved by waiting is $0.50 x 12 pounds = $6.

A prime number is a natural number greater than 1 that has no positive divisors other than 1 and itself. In the case of 11, it can only be divided evenly by 1 and 11, making it a prime number.

The given expression follows the order of operations, also known as PEMDAS/BODMAS. First, we solve the parentheses, which is 5 + 4 = 9. Then, we perform the multiplication, which is 6 * 9 = 54. Next, we perform the division, which is 54 / 3 = 18. Finally, we perform the addition and subtraction from left to right, which is 3 + 18 - 7 = 14. Therefore, the correct answer is 14.

If the arithmetic average of A and B is 14, it means that the sum of A and B is 28. Since C is given as 11, the sum of all three numbers is 28 + 11 = 39. To find the average, we divide the sum by the number of values, which in this case is 3. Therefore, the average of all three numbers is 39/3 = 13.

To divide one fraction by another, multiply the first fraction by the reciprocal of the second. The reciprocal means you swap the top and bottom numbers of the second fraction.

For example, to divide four-fifths by two-thirds, multiply four-fifths by three-halves.

So, four-fifths times three-halves equals twelve over ten.

Then simplify twelve over ten by dividing both top and bottom by two.

Twelve divided by two is six, and ten divided by two is five, so the answer is six-fifths.

This can also be written as one and one-fifth.

The circumference of a circle is calculated using the formula C=2πr, where r represents the radius of the circle. Given that the circle has a radius of 3 units, you can find the circumference by plugging in the radius value:



𝐶 = 2𝜋 × 3 = 6𝜋



Therefore, the circumference of a circle with a radius of 3 units is 6π units. This formula calculates the distance around the circle, an essential concept in geometry. It's crucial for understanding circular measurements and has various applications in mathematics, physics, and engineering.

The given answer is correct. The four consecutive integers that have an arithmetic average of 30.5 are 29, 30, 31, and 32.

The student got 8 out of 50 questions wrong on the test. To calculate the percentage grade, we need to find the percentage of correct answers. The number of correct answers can be calculated by subtracting the number of wrong answers from the total number of questions. So, the student got 42 questions correct (50 - 8 = 42). To find the percentage, we divide the number of correct answers by the total number of questions and multiply by 100. Therefore, the student's percentage grade is 84% (42/50 * 100 = 84%).
