A one-minute advertisement on a local television station during prime time (8- 10 p.m. on weeknights) costs the advertiser $12,8
00. To the nearest cent, how much does the advertisement cost per second? Show your work using dimensional analysis and Giant Ones.
1 answer:
Cost = $12,800
Time = 2 hours, 8 - 10 pm
Cost per hour = ($12800)/(2) = $6400 per hour
There are 60*660 = 3600 seconds per hour.
Therefore the cost per second is
($6400)/(3600 s) = $1.7778 per second = $1.78 per second (nearest cent)
Answer: $1.78 (nearest cent)

Step-by-step explanation:
This is a quick sketch of the problem
the answer is about 235.31 ft
you have to use this equation to get the length of the other side, which is roughly 213 ft:
![100 \div \sin(28)](https://tex.z-dn.net/?f=100%20%5Cdiv%20%20%5Csin%2828%29%20)
then it's just Pythagorean Theorem to get the end result:
![{100}^{2} + {213}^{2} = {c}^{2}](https://tex.z-dn.net/?f=%20%7B100%7D%5E%7B2%7D%20%20%2B%20%20%7B213%7D%5E%7B2%7D%20%20%3D%20%20%7Bc%7D%5E%7B2%7D%20)
