Answer:
1,200 kilometers (km)
Step-by-step explanation:
The scale of a map = 1:30000000
There are two cities that are 4 cm apart on the map
<u>
First: Find the distance between them</u>
Distance between them = 4 cm × 30,000,000 = 120,000,000 cm
<u>Second: Convert</u>
120,000,000 cm = 1,200 km
So distance between the cities is 1,200 km
Answer:
Height of the streetlight ≈ 8 ft(nearest foot)
Step-by-step explanation:
The doc file displays the triangle formed from the illustration. x is the height of the street light. The distance from the gentle man to the street light is 10 ft. He has a height of 5.6 ft and the shadow formed on the ground is 24 ft long. The height of the street light can be calculated below.
The length of the tip of the shadow to the base of the street light is 34 ft. Similar triangle have equal ratio of their corresponding sides .
ab = 5.6 ft
The ratio of the base sides = 24/34
The ratio of the heights = 5.6/x
The two ratio are equal Therefore,
24/34 = 5.6/x
24x = 5.6 × 34
24x = 190.4
divide both side by 24
x = 190.4/24
x = 7.93333333333
x ≈ 8 ft
Height of the streetlight ≈ 8 ft(nearest foot)
