Direct Proportion:

When a decrease in one quantity causes a proportional decrease in another, they are directly related.

Example: If you reduce the number of workers, the amount of work done decreases proportionally.

Rate: Measures change over time (e.g., speed).

Ratio: Compares quantities without implying proportionality.

Inverse Proportion: Increase in one causes decrease in the other (e.g., speed vs. time).

Explanation

Given Data:

m∠B = 120°

Ratio of m∠A : m∠C = 5 : 7

Step-by-Step Solution:

Triangle Angle Sum Property:

m∠A + m∠B + m∠C = 180°

m∠A + 120° + m∠C = 180°

m∠A + m∠C = 60°

Solving Using Ratio:

Let m∠A = 5x and m∠C = 7x

5x + 7x = 60

12x = 60

x = 5

Finding m∠A:

m∠A = 5 × 5 = 25°

Explanation

To find the profit percentage:

Profit = Sale Price - Cost Price

= 2700 - 2500

= 200

Profit Percentage = (Profit / Cost Price) × 100

= (200 / 2500) × 100

= 8%

Explanation

Step-by-step binary addition:

1 + 1 = 10 (0, carry 1)

0 + 1 + 1 (carry) = 10 (0, carry 1)

1 + 1 + 1 (carry) = 11 (1, carry 1)

Final result: (1100)₂

Explanation

Factor the numerator:

(a² - b²) = (a + b)(a - b)

Now, divide by (a + b):

[(a + b)(a - b)] ÷ (a + b)

= (a - b)
