Explanation

Since the sum doubles itself in 15 years, it will quadruple (2 × 2) in 30 years (15 × 2), and become eight times (2 × 2 × 2) in 45 years (15 × 3).

Explanation

The gradient (or slope) of a straight line is calculated as the ratio of vertical change (rise) to horizontal change (run).

This is often written as Δy/Δx, where Δy is the vertical change and Δx is the horizontal change.

Explanation

Ribosomes are the organelles responsible for protein synthesis.

They are often referred to as the "factories of food" because they assemble amino acids into proteins.

They can be found either floating freely in the cytoplasm or attached to the endoplasmic reticulum.

Explanation

Connotative meaning of "cold" describes someone who is unfriendly, distant, or unemotional.

It goes beyond the literal (physical) meaning of low temperature.

Explanation

Given:

1. 6x + 2y = 6300

2. 2x + y = 2600

Multiplying equation (2) by 2:

4x + 2y = 5200

Subtracting:

(6x + 2y) - (4x + 2y) = 6300 - 5200

2x = 1100

x = 550

Explanation

A ray extends infinitely in one direction from its starting point.

Unlike a line which extends in both directions.

It has a definite starting point but no end, traveling in a single direction.

Explanation

The sentence "Wajid gives a well-written statement." follows the Present Indefinite (Simple Present) tense structure: Subject + base verb (+s/es) + object.

The verb "gives" confirms it is in the Present Indefinite tense.

Explanation

Tournament organizers handle planning, scheduling, and logistics to ensure smooth execution.

Umpires and referees focus on enforcing game rules.

Explanation

To find the LCM of 90, 110, and 150:

Step 1: Prime factorize each number.

90 = 2 × 3² × 5

110 = 2 × 5 × 11

150 = 2 × 3 × 5²

Step 2: Identify the highest power of each prime factor.

Highest power of 2: 2¹

Highest power of 3: 3²

Highest power of 5: 5²

Highest power of 11: 11¹

Step 3: Calculate the LCM.

LCM = 2 × 3² × 5² × 11

= 2 × 9 × 25 × 11

= 4950

Explanation

The correct sentence is: "Hurry up or you will miss the bus."

"Or" is used to show a warning or consequence — if you don't hurry, the result will be missing the bus.
