A photograph shows 6 foot tall Mr. Jackson standing next to a building. in the photo Mr .Jackson is 2.5 centimeters tall and the building is 10 centimeters tall. what is the actual height of the building
it's four times as tall in the picture, so it's four times as tall in real life
To determine the actual height of the building, we need to use a proportion. Let's set up the proportion:
(Actual height of building) / (Height of Mr. Jackson) = (Height of building in the photo) / (Height of Mr. Jackson in the photo)
Let's plug in the values we know:
Let x be the actual height of the building.
(x cm) / (6 ft) = (10 cm) / (2.5 cm)
To solve for x, we can cross-multiply and then divide:
(10 cm) * (6 ft) = (2.5 cm) * x
60 cm ft = 2.5 cm x
Dividing both sides by 2.5 cm:
x = (60 cm ft) / 2.5 cm
x = 24 ft
Therefore, the actual height of the building is 24 feet.
