Answer:

16 cm

Step-by-step explanation:

4 cm represents 5 km. There is a total length of 20 km, so you do 20/5=4. Since you have to multiply 5 by 4 to get 20, you also multiply 4cm by 4, and you get 16, or the amount of cm that represents 20 km.

Answer:

The cellphone towers height is 1020 ft.

Step-by-step explanation:

This question is solved using proportions, by a rule of three.

A 10-ft post casts a 14-inch shadow.

Each feet has 12 inches, which means that a post with 10 feet will cast a 14/12 = 1.167 ft shadow. How tall is the cell-phone tower with a 119-feet shadow?

10 feet post - 1.167 ft shadow

x feet tower - 119 feet shadow

Applying cross multiplication:

$1.167x = 10*119$
