At a certain time of day a person 6 feet tall casts a 4-foot shadow How long is the shadow cast by a 21-foot tree at the same time?

Designate the unknown shadow length by s. Shadows cast at the same time and place are proportional to the height of the object casing the shadow. Therefore: 4/6 = s/21, or s = [4(21)]/6 = 14 feet.


Is your shadow always the same height?

NO.


A tree cast a 24-foot shadow at the same time a fence post 5 feet high cast a 4-foot shadow how tall is the tree?

It works out as 30 feet in height


A young man 150 cm tall cast a shadow that was 200 cm long his father's shadow cast at the same time of day was 240 cm long how tall was his father?

The ratio of the young man's height to his shadow is 150:200 or 3:4 The ratio for the father is the same. His shadow is 240 cm so his actual height is 240*3/4 = 180 cm


Thomas happened to notice that like at 4 oclock pm on his unlces farm a fence post that was 5 ft tall cast a 2 foot shadow he also noticed that a nearby tree cast a 10 foot shadow how tall is the tree?

The ratio of the shadow cast to the height of an object will be the same at the same time of day. For the fence post, the height of the post is 2.5 times the length of the shadow ( 5 ft / 2 ft = 2.5 ) The tree has a 10 foot shadow, so using the same ratio for the fence post: 10 ft * 2.5 = 25 feet. The tree is 25 feet tall


What is the height of a flagpole if a person 5 feet tall casts a 10 foot shadow at the same time that the flagpole casts a 40 foot shadow?

The flag pole would be 20 feet. (You can see that the shadows are twice as long.) At a given time of the day, the length of a shadow cast by any object will have the same relationship to its actual height as all other objects. Here the ratio is 5/10 = x/40 and multiplying both sides by 40, 20 = x.


How do you use shadows to measure?

You can use shadows to measure the heights of trees, or buildings, as long as you can make two separate measurements at exactly the same time of day. While one person or group measures the length of the shadow of the tree or other object, another person or group carefully measures the length of the shadow cast by a smaller object, such as a person, sign, or pole.The ratio of the length of the shadow to the height of the object will be the same for almost every object casting a shadow at that particular moment of the day. So divide the known or measured height of a person by the length of his shadow to find this ratio, then multiply the other shadow length by this amount, to give a good estimate of the height of the taller object.Example:A tree's shadow at 5 PM is found to stretch 80 feet from the base of the tree.A boy is known to be 5 feet tall, his shadow at 5 PM is 10 feet long.(So the shadow length of other objects, measured at 5 PM, will all be twice their height.)5 ft/ 10 ft = 0.5 and 0.5 x 80 = 40 tells us the tree itself is about 40 feet tall.


At a certain time of day a tree casts a 9 foot shadow at the same time that a person 6 feet tall casts a 4 foot shadow What is the height of the tree?

If the shadow of a 6-ft person is 4-ft long, then in this place at this moment, all shadowsare 2/3 the length of the vertical object that casts them.The 9-ft shadow therefore 2/3 the height of the tree. The height is (9)/(2/3) = (9 x 3/2) = 13.5-ft.-----------------------------------------(9/4)*6=13.5 ft.


If you're 5 ft 3 inches tall how tall would your shadow be in inches?

It's not possible to give you an answer without knowing the height of your shadow, because the height of a shadow depends on the position of the light (the lower the longer the shadow is). But if the shadow is exactly the same height as you, it would be the same inches in height as you are. To calculate that, just multiply 5 ft x 12, which = 60 inches, then add the other 3 inches to it. That would give you a total of 63 inches.


When the shadow cast by a 1.2 m fence post was 1.8mthe shadow cast by a pine tree was 27.6m and by an oak tree was 45m.How tall was each tree?

There are similar triangles with the shadows as one side, the objects as another and the sun's rays as the third. The ratio of height to shadow is 1.2m : 1.8m = 1.2 : 1.8 = 2 : 3 Therefore to convert shadow length to height divide by 3 and multiply by 2, which is the same as multiplying by 2/3 → height pine = 2/3 × 27.6 m = 18.4 m → height oak = 2/3 × 45 m = 30 m


How is a tree that casts a 28-ft shadow at the same time a 4-ft pole casts a shadow which is 9-ft long?

The height of the tree is in direct proportion to the pole and its shadow
