The figure shows the shadows created by the sun when Cindy stands near the flagpole.
Cindy on the left, she’s ACTUALLY 5 ft and her SHADOW is 4 ft. The flagpole is on the right, we don’t know what the ACTUAL height is but the SHADOW is 10 ft.
What is the closest to the height of the flagpole?
A. 2 ft 6 in.
B. 8 ft ***
C. 12 ft
D. 12 ft 6 in.
Yes.
12.5 = 12 1/2 = 12 feet, 6 inches
Yes.
Im really not sure how to do this
Use a proportion.
5/4 = x/10
Cross multiply and solve for x.
4x = 50
x = ?
50/4 = 12.5 there is no 12.5 up here would it be D?
wow. ms sue is awesome. are you a real teacher?
To find the height of the flagpole, we can use proportions. Let's set up a proportion using the lengths of the shadows:
Cindy's height / Cindy's shadow = Flagpole's height / Flagpole's shadow
Plugging in the known values:
5 ft / 4 ft = Flagpole's height / 10 ft
Now, cross-multiply and solve for the flagpole's height:
5 ft * 10 ft = 4 ft * Flagpole's height
50 ft = 4 ft * Flagpole's height
50 ft / 4 ft = Flagpole's height
12.5 ft = Flagpole's height
The closest option to the height of the flagpole is 12 ft, which is option C.
