7) 40m = 40/1000 = 0.04km

8) 84m = 84/1000 = 0.84km

9) 63m = 63/1000 = 0.63km

10) 6.1cm = 6.1 × 10 = 61mm

11) 0.6cm = 0.6 × 10 = 6mm

12) 2.9cm = 2.9 × 10 = 29mm

13) 10m = 10 × 100 = 1000cm

14) 43m = 43 × 100 = 4300cm

The sears tower in chicago is 1450 feet high. A model of the tower is 24 inches tall. What is the ratio of the height of the mod

Dominik [7]

Answer:

$\frac{1}{725}$

The sear tower is $725$ times higher than the sears tower model

Step-by-step explanation:

we know that

The ratio of the height of the model to the height of the actual sears tower is equal to the scale factor

Let

z------> the scale factor

x-------> the height of the model

y-------> the height of the actual

$z=\frac{x}{y}$

we have

$x=24\ in$

$y=1,450\ ft$

substitute

$z=\frac{24}{1,450}\frac{in}{ft}$

simplify

$z=\frac{12}{725}\frac{in}{ft}$

Remember that

$1\ ft=12\ in$

$\frac{12}{725}\frac{in}{ft}=\frac{1}{725}\frac{ft}{ft}$
