<span>At 8in to 250 feet the skyscraper converts to the following.
1.6 in/8 in x 250ft = 50 ft long
2.8in/8in x 250ft = 87.5 ft wide
11.2in/8in x 250ft = 350 ft high
You get this because every 8 in is 250 feet so you need to calculate the ratio of scale to that 8in per 250 feet.</span>
It would be
(1) x
- 
So it's the first option.
Good luck! (:
Answer:
37.7 m
Step-by-step explanation:
Use this formula:
A=2πrh+2π
Answer: The answer is B. 0.2
Step-by-step explanation:
You simply have to divide 0.4 by 0.08 in order to get your answer
You can rewrite your function as

This implies that

Now, we have
, so it counts as a solution.
On the other hand, depending on the coefficient a, b and c, the cubic equation

can have either one or three solutions.
So, we have the solution x=0, and then one or three solutions coming from the cubic part. The equation as a whole thus have either two or four solutions, depending on the coefficients.
