Answer: 
Step-by-step explanation:
You need to draw a right triangle as the one attached, where 
is the angle of elevation from the fire to the top of the fire tower.
You need to use the Inverse trigonometric function Arctangent:
Observe the triangle. You can identify that:
Then, you can substitute values:
Finally, evaluating, you get that the angle of elevation from the fire to the top of the fire tower is the following:
Rounded to the the nearest tenth of a degree:
1 kg is equal to 1,000 g. So, in order to convert, you need to multiply 20x1,000. To get 20,000 g.
Answer:
Yes, GCF stands for (greatest common factor)

Step-by-step explanation:
The population of New York City is about 8.18 × 10^6. This is an estimation. The population of Las Vegas is about 5.84 × 10^5. This is also an estimation. We want to determine the number of times that population of new York is more than that of las Vegas. It's like saying how many las Vegas are the in New york.
This is done by dividing the population of new York by the population of las Vegas. It becomes
8.18 × 10^6 / 5.84 × 10^5
= 14.00684931507
