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

1) quarter- pound can be written as 1/4 pound
100:1/4=100*4=400
400 <span> hamburgers

2) The difference between these temperatures 212-32=180
180

Any number that is more than 32 and less than 212 is between this temperatures.
For example 40, and 136 lie between 32 and 212.

3) 1000, 100, 10, 1...
We can see that every next number 10 times less than previous number,
so after 1 should be 1/10=0.1
If it is written as fraction 1/10, if it is written as decimal 0.1.</span>
