The expected population of each country in 2025 are 22261221, 1465382683, 116537821 and 60347662

<h3>The expected population in 2025</h3>

The expected population of each country is calculated as:

P(n) = a *(1 + r)^n

Where:

a represents the initial population
r represents the growth rate
n represents the number of years since 2000

2025 is 25 years since 2000.

This means that:

n = 25

So, we have:

Australia

P(25)= 19169000 * (1 + 0.6%)^25

P(25)= 22261221

China

P(25)= 1261832000* (1 + 0.6%)^25

P(25)= 1465382683

Mexico

P(25)= 100350000 * (1 + 0.6%)^25

P(25)= 116537821

Zaire

P(25)= 51965000* (1 + 0.6%)^25

P(25)= 60347662

Hence, the expected population of each country in 2025 are 22261221, 1465382683, 116537821 and 60347662

2x - 3y = 12 x = 4y + 1

aliya0001 [1]

Answer:

x = 9, y = 2 is the solution of the given system.

Step-by-step explanation:

Here, the given set of equation is :

2 x - 3 y = 12

x = 4 y + 1

Now, from equation (2) we see that x = 4 y + 1.

Substitute the value of y from (2) in the first equation. we get:

2 x - 3 y = 12 ⇒ 2 (4 y + 1) - 3 y = 12

or, 8 y + 2 - 3 y = 12

or, 5 y = 12- 2 = 10

or, y = 10/ 5 = 2

or, y = 2

Now, x = 4 y + 1 ⇒ x = 4(2) + 1 = 8 + 1 = 9, or x = 9

Hence, x = 9, y = 2 is the solution of the given system.

The map shows the intersection of three roads. Malcom Way intersects Sydney Street at an angle of 162°. Park Road intersects Syd

Y_Kistochka [10]

Answer:

The angle at which malcom Way intersects Park Road = 111 °

Step-by-step explanation:

Malcom Way intersects Sydney Street at $\theta_{1}$ = 162 °

Park Road intersects Sydney Street at $\theta_{2}$ = 87 °

The angle at which Malcom Way intersects Park Road $\theta_{3}$ = ?

We know that

$\theta_{1} + \theta_{2} + \theta_{3} = 360$

$\theta_{3} = 360 - \theta_{1} - \theta_{2}$

$\theta_{3} = 360 - 162 - 87$

$\theta_{3} = 111$ °

Therefore the angle at which malcom Way intersects Park Road = 111 °
