In a photograph, a man is 1.3cm tall and a flagpole is 4.8cm tall. If the man is 190 cm in real life, how tall is the flagpole, to the nearest centimetre?
1.3 / 190 = 4.8 / x
1.3x = 912
x = 702 cm
Well, if we consider the man's height in the photograph as 1.3 cm and his real-life height as 190 cm, we can establish a proportion. Let's call the height of the flagpole in real life "x" cm.
Thus, we can set up the following equation:
1.3 cm (man's height in the photo) : 190 cm (man's height in real life) = 4.8 cm (flagpole's height in the photo) : x cm (flagpole's height in real life)
To solve for "x," we can cross-multiply:
1.3 cm * x cm = 4.8 cm * 190 cm
Now, let me use my highly advanced calculating powers to figure that out... hold on... *boop boop beep beep* Ah, here it is!
x = (4.8 cm * 190 cm) / 1.3 cm
Calculating... calculating... and... *drumroll*
The height of the flagpole in real life is approximately 702.4615384615385 cm.
Hmm, that's a rather specific answer, isn't it? How about we round it up to the nearest centimeter? So, the flagpole is about 702 cm tall.
To find the height of the flagpole in real life, we can set up a proportion using the known measurements.
Let x be the height of the flagpole in real life.
According to the given measurements:
Man's height in the photograph = 1.3 cm
Flagpole's height in the photograph = 4.8 cm
Using the proportion:
(man's height in real life) / (man's height in the photograph) = (flagpole's height in real life) / (flagpole's height in the photograph)
190 cm / 1.3 cm = x / 4.8 cm
Cross-multiplying, we have:
190 cm * 4.8 cm = 1.3 cm * x
912 cm = 1.3 cm * x
Now, we can solve for x by dividing both sides of the equation by 1.3 cm:
912 cm / 1.3 cm = x
x ≈ 701.54 cm
Therefore, the height of the flagpole in real life is approximately 701.54 cm or 702 cm (rounded to the nearest centimetre).
To find the height of the flagpole in real life, we can set up a proportion using the information given.
Let's start by establishing the ratio between the height of the man in the photograph and his actual height:
1.3 cm (height in the photograph) / 190 cm (actual height) = x cm (height of the flagpole) / 4.8 cm (height in the photograph)
To solve for x (height of the flagpole), we can cross-multiply and then divide:
1.3 cm * x cm = 190 cm * 4.8 cm
x cm = (190 cm * 4.8 cm) / 1.3 cm
x cm = 700.8 cm / 1.3 cm
x cm ≈ 539.08 cm
The height of the flagpole, to the nearest centimetre, is approximately 539 cm.
