otis is tall
9/1.125=8 The tree is 8 feet tall
First I used the proportion method to set up the numbers. I used x for the height of the tree.
x/9 = 4/4.5
Notice that the height of the tree and Otis's height are both the numerators (top numbers) of the fractions. Also, the height of the tree and the length of its shadow are one fraction, and Otis's height and his length are another separate fraction.
Same with the length of the tree's shadow and the length of Otis's shadow. They are both denominators (bottom numbers) of the fractions.
Next, I did 4 times 9 and got 36. Then I did 36 divided by 4.5 and got 8.
You're welcome! :)
We can use ratios to solve
tree shadow Otis shadow
tree 4 ft
9 ft 4.5 ft
Using cross products
4.5 tree = 4* 9
4.5 tree = 36
Divide each side by 4.5
tree = 36/4.5
The correct answer is: The height of the tree is 8 feet (or the tree is 8 feet tall).
Please see the picture attached with the same.
Tree's shadow is 9 feet long.
Otis is 4 feet tall.
Otis' shadow is 4.5 feet long.
We need to find out how tall the tree is.
The ratios of both of their height and their shadows should be the same, as follows:
The tree is 8 feet tall.
otis is 4 feet tall, and he is standing next to the tre...
