Explanation

Given the equations:

x + 3y = 53 ... (1)

4x - 2y = 2 ... (2)

We can solve these equations using substitution or elimination. Let's use elimination.

Multiplying equation (1) by 2 and equation (2) by 3 to eliminate y:

2x + 6y = 106

12x - 6y = 6

Adding both equations:

14x = 112

x = 8

Explanation

Let's simplify the expression:

√1-sin²θ/sinθ = √(cos²θ)/sinθ (since 1 - sin²θ = cos²θ)

= cosθ/sinθ

= cotθ

Explanation

Nylon actually has excellent abrasion resistance, not poor.

It is also highly resilient, resistant to insects, fungi, and many chemicals.

Explanation

A group of wolves is called a pack.

"Herd" is used for cattle or deer.

Explanation

In a DNA molecule, adenine (A) always pairs with thymine (T) through two hydrogen bonds.

This specific pairing maintains the structure and stability of the DNA double helix.

Explanation

Given that 12 men can water the field in 9 hours, we can calculate the total man-hours required:

Total man-hours = 12 men * 9 hours = 108 man-hours

If the same field needs to be watered in 4 hours, let's denote the number of men required as x:

x men * 4 hours = 108 man-hours

x = 108 / 4

x = 27

Explanation

First, next, then, after that, finally

This sequence follows a logical, chronological order for presenting events.

It appropriately arranges the markers from beginning to end.

Explanation

The area of the sector can be calculated using the formula: Area = (θ/360) * πr², where θ is the central angle and r is the radius.

Given θ = 60° and r = 5 cm, we can substitute these values into the formula:

Area = (60/360) * π * (5)²

Area = (1/6) * π * 25

Area ≈ (1/6) * 3.14 * 25

Area ≈ 13.08 cm²

Explanation

Modern teaching emphasizes interaction between teacher and student, making it a two-way communication.

It focuses on both teaching (delivery) and learning (reception and understanding) to achieve effective outcomes.
