A model of a building is 18 inches tall. If the building is really 678 feet tall, how tall is a window that is 1/9 in on the mod
ipn [44]

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 = \frac{1}{9}in

Rb = real building = 678ft = 8136in

Rw = real window = ?

\frac{Mw}{Mb} = \frac{Rw}{Rb}

\frac{1/9}{18} = \frac{Rw}{8136}

\frac{1}{9*18} = \frac{Rw}{8136}  

\frac{1}{162} = \frac{Rw}{8136}

\frac{1*8136}{162}= \frac{8136*Rw}{8136}

\frac{8136}{162} = Rw

\frac{452}{9} = Rw

Rw ≈ 50.2in ≈ 4.2ft

the difference between 2 whole number is 66 the ratio of the 2 whole number is 2.5 what are the two numbers​​
ch4aika [34]

Given :difference between 2 whole number = 66ratio of the 2 whole number =2:5Let:1 whole number be 2x2 whole number be 5xA/Q

difference between 2 whole number = 66

Let's turn it into algebraic equation:

5x - 2x = 663x= 66x =66 /3x =22

Now Let's put value of x to find two whole numbers

Finaly :1 whole number = 2x1 whole number = 2×221 whole number =44

2 whole number = 5x2 whole number = 5×222 whole number = 110
