An architect is designing an office building with n floors that will have an FM radio antenna 15.85m tall on its roof. Each floor of the building will be 3.9m high. Which equation can be used to find the total height, h, of the building in meters, including the FM antenna?
A. h= 15.85n + 3.9
B. h = 3.9n + 15.85
C. h = 3.9 - 15.85
D. h = 19.75n
I think it is D. I am not sure though. Can someone help?
Wrong. Its B
The office building is designed with n floors and each floor is 3.9m right so you have right now: 3.9n
On top of entire office building is a antenna which is 15.85m tall so its
3.9n + 15.85 = h
To find the total height of the building, including the FM antenna, we need to add the height of each floor to the height of the antenna.
Since each floor is 3.9m high, the total height contributed by the floors will be 3.9n, where n represents the number of floors.
The height of the FM antenna is 15.85m.
So, the equation to find the total height, h, of the building, including the FM antenna, is given by:
h = 3.9n + 15.85
Therefore, the correct equation is A. h = 3.9n + 15.85.
Thank you, Thomas! You are not being rude. You are trying to help this misguided student -- whatever his/her name is.
