Answer:
50.2in or 4.2ft
Step-by-step explanation:
This is a problem about proportions so I generally set up my problems like below. I just set some variable here to make it easier to refer back to the measurements for each. You don't have to do this, I am just showing it for clarity. I will convert everything to inches too. We need to find the real window height.
Mb = model building = 18in
Mw= model window =
in
Rb = real building = 678ft = 8136in
Rw = real window = ?
= ![\frac{Rw}{Rb}](https://tex.z-dn.net/?f=%5Cfrac%7BRw%7D%7BRb%7D)
= ![\frac{Rw}{8136}](https://tex.z-dn.net/?f=%5Cfrac%7BRw%7D%7B8136%7D)
=
= ![\frac{Rw}{8136}](https://tex.z-dn.net/?f=%5Cfrac%7BRw%7D%7B8136%7D)
= ![\frac{8136*Rw}{8136}](https://tex.z-dn.net/?f=%5Cfrac%7B8136%2ARw%7D%7B8136%7D)
= Rw
= Rw
Rw ≈ 50.2in ≈ 4.2ft
No it isn’t correct, it’s the second one! Good luck!
Answer:
2,3 &13
Step-by-step explanation:
78=2times39=3times13
therefore the prime factors of 78=2,3,13
