Answer:
370 million
Step-by-step explanation:
In the 10 years from 2000 to 2010, the population was multiplied by the factor ...
100% + 9.6% = 109.6% = 1.096
In the next 20 years from 2010 to 2030, the population will be multiplied by that factor twice, if it grows at the same rate:
2030 population = (308 million)·(1.096²) ≈ 370 million

In total she will pay $80.30
Answer:
![\frac{4\sqrt{3} }3}](https://tex.z-dn.net/?f=%5Cfrac%7B4%5Csqrt%7B3%7D%20%7D3%7D)
Step-by-step explanation:
Since it is an equilaterla triangle, we can see the side opposite to that of side length 4 is 60 degrees. Since the other angle is a right angle (90 degrees), we can find that the other side is 30 degrees (the degrees add up to 180). We can also see that this is a 30-60-90. We can see that the side x, through the identity (you can find 30-60-90 identity online), we see that the side x is
. However, it is also asking us to simplify this, so we multiply the top and bottom by
and get ![\frac{4}{\sqrt{3} } = \frac{4\sqrt{3} }{3}](https://tex.z-dn.net/?f=%5Cfrac%7B4%7D%7B%5Csqrt%7B3%7D%20%7D%20%3D%20%5Cfrac%7B4%5Csqrt%7B3%7D%20%7D%7B3%7D)
Answer:
x = -2
Step-by-step explanation:
Distribute: 18x + 24 = 4x - 4
Subtract 4x from both sides: 14x + 24 = -4
Subtract 24 from both sides: 14x = -28
Divide both sides by 14: x = -2
