Estimating the number of internet users in Europe by multiplying the ratio with the whole internet users
users in Europe = 9/40 × 2.1 billion
users in Europe = 9/40 × 2,100 million
users in Europe = (9 × 2,100)/40 million
users in Europe = 18,900/40 million
users in Europe = 472.5 million
The number of internet users in Europe is approximately 472.5 million at this time
Answer: 2
Step-by-step explanation:
2.5(6x-4)=10+4(1.5+0.5x) [Work out the brackets]
15x-10=0+6+2x [Solve]
15x-10=16+2x [Convey the terms]
15x-2x=16+10 [Add up the same terms and calculate]
13x=26 [Divide both parts]
x=2
Its sideways and I cant read it
Answer:
860cm²
Step-by-step explanation:
1. area of the side triangle:
(15×8)×2= 120×2= 240cm²
there's two side triangles with the same length and width, so just multiply by two.
2. area of the square on top:
20×8= 160cm²
3. area of the rectangle behind:
20×8= 160cm²
4. area of the square below:
20×15= 300cm²
5. the total of all areas (surface area):
240+160+160+300= 860cm²
