Explanation

We can simplify the expression using the identity:  

a³ + b³ = (a + b)(a² - ab + b²)

Here,  

a = 8.73, b = 4.27  

a + b = 13  

a² = 8.73² = 76.2129  

b² = 4.27² = 18.2329  

ab = 8.73 × 4.27 = 37.2671  

Now,  

a³ + b³ = (13)(76.2129 - 37.2671 + 18.2329)  

= 13 × (57.1787)  

≈ 743.3

Explanation

 We are given:

Average of 6 numbers = 10

So, total sum = 10 × 6 = 60

If each number is multiplied by 3, then the new total becomes:

New total = 60 × 3 = 180

Number of values = still 6

New average = 180 ÷ 6 = 30

Explanation

We are given:

• Average age of 3 people = 25

• So, total age = 25 × 3 = 75

Their ages are in the ratio 3:5:7, which means:

Let their ages be 3x, 5x, and 7x

• Total = 3x + 5x + 7x = 15x

Set 15x = 75
⇒ x = 5

So, the ages are:

• 3x = 15

• 5x = 25

• 7x = 35

The lowest age is 15

Explanation

2A = 3B = 4C

Let k = 2A = 3B = 4C

Now solve for A, B, and C:

- A = k / 2  

- B = k / 3  

- C = k / 4

Now take the ratio A : B : C:

= (k/2) : (k/3) : (k/4)

Multiply all terms by 12 to eliminate denominators: = 6 : 4 : 3

These systems help in monitoring, detecting threats, and controlling entry to sensitive areas.

Explanation

Vision 2030 aims to diversify Saudi Arabia’s economy, opening doors for Pakistani workers and professionals.

It encourages foreign investment, including from and into Pakistan.

It strengthens bilateral ties through joint projects and strategic cooperation.

Explanation

Given:

a : b : c = 2 : 5 (let's assume a common multiple for b and c to match both ratios)

b : c = 3 : 7

To match both ratios, let's find the LCM for b in both ratios.

Given a : b = 2 : 5 and b : c = 3 : 7, let's make the ratios comparable by finding a common multiple for b.

For a : b = 2 : 5 and b : c = 3 : 7,

let's scale a : b : c = 2_3 : 5_3 : 5*7 = 6 : 15 : 35

Now b : c = 15 : 35 which simplifies to 3 : 7.

Given a : b : c = 6 : 15 : 35

a : c = 6 : 35
