Explanation

The problem of putting n letters into n envelopes such that no letter goes into its correct address envelope is a classic case of derangements. The formula for the number of derangements of n objects is:

Dₙ = n! ( (1)/(2!) - (1)/(3!) + (1)/(4!) - … + ((-1)ⁿ)/(n!) )

For n = 3 letters and envelopes, substituting the value into the formula yields:

D₃ = 3! ( (1)/(2!) - (1)/(3!) )

D₃ = 6 ( ½ - ⅙ )

D₃ = 6 ( ²⁄₆ ) = 2

Explanation

Using the rule of alligation, the ratio of the number of boys to the number of girls in the class is calculated as:

(Number of Boys)/(Number of Girls) = (Average marks of all students - Average marks of girls)/(Average marks of boys - Average marks of all students)

Substituting the given values into the formula:

(Number of Boys)/(Number of Girls) = (50 - 42)/(52 - 50) = ⁸⁄₂ = ⁴⁄₁

Thus, the ratio of boys to girls is 4:1.

The percentage of boys in the class is:

(4)/(4 + 1) × 100% = ⅘ × 100% = 80%

Explanation

Let standard Cartesian unit vectors i and j represent the East and North directions respectively on a two-dimensional plane, with the starting position at the origin (0, 0).

The individual movements can be represented as displacement vectors in kilometers:

First, walking 500 m (0.5 km) North-East: v₁ = 0.5 cos(45°) i + 0.5 sin(45°) j = (1)/(2√(2)) i + (1)/(2√(2)) j

Second, walking 1 km South: v₂ = -j

Third, turning right from South (which is West) and walking 1 km: v₃ = -i

Fourth, walking 500 m (0.5 km) South-West: v₄ = -0.5 cos(45°) i - 0.5 sin(45°) j = -(1)/(2√(2)) i - (1)/(2√(2)) j

Fifth, walking 1 km North: v₅ = j

The total displacement vector D from the starting position is the sum of these five vectors: D = v₁ + v₂ + v₃ + v₄ + v₅ D = ((1)/(2√(2)) i + (1)/(2√(2)) j) - j - i - ((1)/(2√(2)) i + (1)/(2√(2)) j) + j

Combining the terms simplifies to: D = -i

The net displacement vector is 1 km in the negative x-direction, which corresponds to 1 km West of the initial starting point.

Explanation

Mangrove forests are highly efficient at sequestering and storing carbon, especially in their anoxic soils (blue carbon). Their dense root systems and waterlogged conditions prevent rapid decomposition, leading to large accumulations of organic carbon per hectare compared to terrestrial forest types like sal, tropical moist deciduous, or temperate evergreen forests.

Explanation

The work done W by a force F over a displacement dr is given by the line integral:

W = ∫ F · dr = ∫ F cosθ ds

where θ is the angle between the force vector and the displacement vector. For a planet revolving in a circular orbit around the sun, the gravitational force acts radially inward toward the center of the orbit. The displacement of the planet at any instant is along the tangent to the circular path. Since the radius of a circle is always perpendicular to its tangent, the angle θ between the gravitational force and the instantaneous displacement is always 90°. Substituting cos(90°) = 0 into the equation gives:

W = ∫ F cos(90°) ds = 0

The work done by the gravitational force in moving the planet over half the circumference, or any other distance along the circular path, is zero.

Explanation

Let C be the number of correct answers, U the number of unattempted questions, and W the number of wrong answers. Total questions = 30, so C + U + W = 30. The total score S = 4C + 1U + 0W = 4C + U. We must have C >= 0, U >= 0, W >= 0.

From C + U + W = 30, we have U = 30 - C - W. Substitute U into the score equation: S = 4C + (30 - C - W) = 3C + 30 - W.

For any score S to be attainable, we must find integers C, U, W satisfying the conditions. From U >= 0, we have S - 4C >= 0, which means S >= 4C or C <= S/4. From W >= 0, we have 30 - C - U >= 0. Substituting U = S - 4C, we get 30 - C - (S - 4C) >= 0 => 30 + 3C - S >= 0 => 3C >= S - 30 or C >= (S - 30)/3. Thus, for a score S to be attainable, there must exist an integer C such that (S - 30)/3 <= C <= S/4.

Let's check the given options: a) For S = 113: (113 - 30)/3 <= C <= 113/4 => 83/3 <= C <= 28.25 => 27.66... <= C <= 28.25. C = 28 is a possible integer. So 113 is attainable. b) For S = 114: (114 - 30)/3 <= C <= 114/4 => 84/3 <= C <= 28.5 => 28 <= C <= 28.5. C = 28 is a possible integer. So 114 is attainable. c) For S = 115: (115 - 30)/3 <= C <= 115/4 => 85/3 <= C <= 28.75 => 28.33... <= C <= 28.75. There is no integer C in this range. So 115 is not attainable. d) For S = 117: (117 - 30)/3 <= C <= 117/4 => 87/3 <= C <= 29.25 => 29 <= C <= 29.25. C = 29 is a possible integer. So 117 is attainable.

Therefore, 115 is the score that is not attainable by a student.

Explanation

Hydrogen bonding is a strong electrostatic attraction that occurs when a hydrogen atom is covalently bound to a highly electronegative atom with a small atomic radius, specifically fluorine, oxygen, or nitrogen. In H₂O and HF, the highly electronegative oxygen and fluorine atoms pull the shared electron density strongly toward themselves, creating a significant partial positive charge on the hydrogen atom. This allows the hydrogen atom to form hydrogen bonds with the lone pairs of adjacent molecules. In contrast, sulfur in H₂S has a much lower electronegativity and a larger atomic size with a more diffuse electron cloud, which prevents the formation of hydrogen bonds.

Explanation

After paying 18 installments, 60% of the loan was refunded. To find the total number of installments, we can set up a proportion: if 18 installments represent 60% of the loan, then the total number of installments (T) will represent 100% of the loan. This gives the equation 18 / 0.60 = T / 1, which simplifies to T = 18 / 0.60 = 30.

Explanation

In typical GPS navigation maps set to track-up mode, the forward direction of the vehicle's travel is always oriented toward the top of the screen (12 o'clock position).

The screen directions relative to this top-center forward direction are defined as: Top-center (12 o'clock) represents the current travel direction (0°). Right (3 o'clock) represents 90° clockwise. Bottom-right corner (4:30 o'clock) represents approximately 135° clockwise.

Since the map shows North in the bottom-right corner, North is located 135° clockwise from the vehicle's direction of travel. This implies that the vehicle's current direction of travel is 135° counter-clockwise from North. On a standard compass rose, 135° counter-clockwise from North (which is 360° - 135° = 225°) corresponds to South-West.

When the vehicle turns 90° to the left, its direction of travel rotates 90° counter-clockwise from its initial heading: New Direction = 225° - 90° = 135°

On a standard compass rose, a heading of 135° corresponds directly to South-East.
