Study Notes
Volume Calculation
- Volume of a rectangular box is calculated using the formula: Length × Width × Height.
- Given dimensions: 3 cm (height) × 4 cm (length) × 5 cm (width) results in a volume of 60 cm³.
Maximum Integer Divisibility
- For a positive integer n divisible by 7 and n < 70, the largest possible value is 63.
- This is derived from finding multiples of 7 below 70.
Arithmetic Mean Problem
- Blair's average score across two tests is 7, requiring a third test score of 10 to achieve an average of 8.
- Calculation involves determining the necessary sum for an increased average, resulting in 3 tests.
Polynomial Multiplication
- Expanding the expression (4x + 2)(x + 1) yields 4x² + 6x + 2.
- Multiplicative distribution is key in combining like terms.
Order of Operations
- In evaluating 2 − 8 ÷ (24 ÷ 2), applying the order of operations leads to a result of 1.
Solving Linear Equations
- For 3(x − 4) = 18, solving gives x = 10 after isolating x through basic algebra.
Understanding Mode
- The mode of a dataset refers to the most frequently occurring value.
- In this scenario, the mode is 0, indicating the highest count among scouts.
Line Equation Determination
- A line passing through (−1, 2) cannot be represented by the equation y = x + 1, as it would not satisfy this point.
Exponent Calculation
- For the equation 511 = 52 × 5ᵐ, solving for m reveals m = 9 by utilizing the properties of exponents.
Expression Simplification
- Simplifying 3x³y⁵ + 3x⁵y³ − (4x⁵y³ − 3x³y⁵) results in 6x³y⁵ − x⁵y³ through correct distribution of the negative sign.
Perimeter of a Rectangle
- When a rectangle is divided into two squares of area 25 each, the rectangle’s perimeter is calculated as 30.
Inferencing in Right Triangles
- In a right triangle with equal sides, angles a and b sum to 90 degrees, confirming that the hypotenuse is the longest side.
Square Root Calculation
- The expression evaluates to 13 after adding 25 and 144, and subsequently applying the square root.
Solving for Zero
- The equation (3.2 + 3.3 + 3.5)w = w indicates w must be 0 to satisfy the equation.
System of Equations
- For burnt pizzas, if oven 1 burns three times as many as oven 2, and the total is 12, oven 2 burns 3 pizzas.
Trapezoid Area Calculation
- The area of a trapezoid can be derived by computing areas of constituent shapes, like rectangles and triangles, leading to a total area of 570.
Solving Simultaneous Equations
- Given x + y = 2 and x − y = 1, the solution is x = 3/2 and y = 1/2 after solving the system.
