A frame of movie film is 35mm wide and 26.25mm high. The film projects an image 8m wide. How high is the image?
35/26.25 = 8/h
35h = 8(26.5)
h = .....
The answer is 6
35mm wide/26.25mm high = 8 wide
What is is high?
=26.25 x 8 = 210
=210 / 35 = 6
To calculate the height of the image, we can use proportions.
First, let's convert the width of the film from millimeters to meters:
1 meter = 1000 millimeters
35mm / 1000 = 0.035m
Now, we can set up a proportion to find the height of the image:
width of the film / height of the film = width of the image / height of the image
0.035m / 26.25mm = 8m / x
To find x (the height of the image), we can cross multiply:
0.035m * x = 26.25mm * 8m
0.035x = 210mm
Now, let's convert the result back to meters:
x = 210mm / 1000 = 0.21m
Therefore, the height of the image projected by the film is 0.21 meters.
