Explanation

An equilateral triangle has all three sides and angles equal (each angle = 60°).

It is commonly used in geometry and structural design for uniform load distribution.

A scalene triangle has no equal sides and no equal angles.

All sides and angles are of different lengths and measures.

Explanation

Acute angles measure less than 90 degrees.

Right angles measure 90 degrees.

Obtuse angles measure more than 90 degrees.

Explanation

1 mile = 1,609.34 meters = 160,934 cm.

Used in unit conversions for distance measurements.

Explanation

Formula:  

Percentage = (Present Students / Total Students) × 100

Given:  

Present = 340  

Total = 500

Calculation:  

(340 ÷ 500) × 100 = 0.68 × 100 = 68%

Explanation

Explanation

13 mod 5 = 3

17 mod 5 = 2

(13 × 17) mod 5 = (3 × 2) mod 5

= 6 mod 5

= 1

Explanation

a = 3, r = 2

5th term:

3, 6, 12, 24, 48

Explanation

The number of ways to choose 2 elements from 5 is 5C2 = 5! / (2! × 3!) = 10.

This represents the combinations where order does not matter.

Explanation

The number of arrangements of 4 distinct books is 4! = 4 × 3 × 2 × 1 = 24.

This represents all possible permutations of the books on the shelf.

Explanation

Mode = 11, Mean = 12

Using:

Mean - Mode ≈ 3(Mean - Median)

12 - 11 = 3(12 - Median)

1 = 36 - 3Median

3Median = 35

Median = 35/3

= 11.67
