Detailed Explanations of Answers

Let's break down these maths quiz answers so you can see how they're derived. Understanding the "why" behind the answer is just as crucial as getting the answer right. Understanding the 'why' will help improve your maths skills!

1. Pi (π) is a mathematical constant that represents the ratio of a circle's circumference to its diameter. While Pi is an irrational number (meaning its decimal representation goes on forever without repeating), for most practical purposes, it's often approximated to two decimal places as 3.14. This value is widely used in calculations involving circles, spheres, and other geometric shapes. So, if you answered 3.14, you nailed it!
2. To solve the equation 2x + 5 = 11, we need to isolate 'x'. First, subtract 5 from both sides of the equation: 2x = 6. Then, divide both sides by 2 to get x = 3. Therefore, the solution to the equation is x = 3. Remember the order of operations (PEMDAS/BODMAS) – Parentheses/Brackets, Exponents/Orders, Multiplication and Division (from left to right), and Addition and Subtraction (from left to right) – to ensure you solve equations correctly.
3. The area of a circle is calculated using the formula A = πr², where 'A' is the area and 'r' is the radius. Given that the radius is 7, we can plug this value into the formula: A = π(7²) = π(49). Using the approximation of π as 3.14, we get A ≈ 3.14 * 49 ≈ 153.86. Rounding to two decimal places, the area of the circle is approximately 153.86 square units. Always remember to include the appropriate units (e.g., square inches, square centimeters) when expressing area.
4. The Fibonacci sequence is a series of numbers in which each number is the sum of the two preceding ones. The sequence starts with 1, 1, and continues as follows: 1, 1, 2, 3, 5, 8, 13, 21, and so on. To find the next number in the sequence after 8, we add the two preceding numbers: 5 + 8 = 13. Therefore, the next number in the Fibonacci sequence is 13. This sequence appears in various natural phenomena, from the arrangement of leaves on a stem to the spiral patterns of galaxies.
5. To calculate 15% of 200, we can convert the percentage to a decimal by dividing it by 100: 15% = 0.15. Then, multiply the decimal by the number: 0.15 * 200 = 30. Therefore, 15% of 200 is 30. Percentages are a fundamental concept in mathematics and are used in a wide range of applications, such as calculating discounts, taxes, and interest rates.
6. The square root of a number is a value that, when multiplied by itself, equals the original number. In this case, we're looking for the square root of 144. Since 12 * 12 = 144, the square root of 144 is 12. The square root symbol is √, so √144 = 12. Understanding square roots is essential for solving various mathematical problems, including those involving geometry, algebra, and calculus.
7. To calculate the time it takes for a train to travel 300 miles at a speed of 60 mph, we can use the formula: time = distance / speed. Plugging in the given values, we get: time = 300 miles / 60 mph = 5 hours. Therefore, it will take the train 5 hours to travel 300 miles. This type of problem involves the concept of rate, time, and distance, which is a fundamental topic in algebra and physics.
8. The sum of the angles in a triangle is always 180 degrees. This is a fundamental theorem in Euclidean geometry. Regardless of the shape or size of the triangle, the three interior angles will always add up to 180 degrees. For example, in a right triangle, one angle is 90 degrees, and the other two angles must add up to 90 degrees as well.
9. The volume of a cube is calculated using the formula V = s³, where 'V' is the volume and 's' is the length of a side. Given that the sides of the cube have a length of 4, we can plug this value into the formula: V = 4³ = 4 * 4 * 4 = 64. Therefore, the volume of the cube is 64 cubic units. Always remember to include the appropriate units (e.g., cubic inches, cubic centimeters) when expressing volume.
10. A factorial (denoted by the symbol "!") is the product of all positive integers less than or equal to a given number. For example, 5! = 5 * 4 * 3 * 2 * 1 = 120. To calculate 7!, we multiply all positive integers from 1 to 7: 7! = 7 * 6 * 5 * 4 * 3 * 2 * 1 = 5040. Factorials are used in various areas of mathematics, including combinatorics, probability, and calculus.
