How tall is a person that casts a 9 foot shadow?
Depends on the time of day (the angle of the sun). Think of the person as being at a right angle to the ground, and the shadow being the other side. The distance from the person's head to the end of the shadow is the hypotenuse. (a^2 + b^2= c^2) a= height of person, b= shadow. If you have the angle of the sun to the ground, you can use Sine/ Cosine to calculate the length.
What is 54 feet by 10 legs and 20 arms?
The answer depends on what you are actually asking. If you mean 54 ft x the length of 10 legs + the length of 20 arms, then you can express it as "54 ft x (the length of 10 legs + the length of 20 arms)". If you know the actual length of each leg & each arm, then you could add the lengths of each leg & the lengths of each arm & and you could maken an expression such as: "54 ft x (TL leg ft + TL arm ft) If you know the average leg length & average arm length, then you could maken an expression such as: "54 ft x (10 x aver leg len + 20 x aver arm len) Lastly, if you know such lengths, you could multiple 54 x TL length of the appendage to arrive at total square feet number.
The width of a rectangle is one half its length the perimeter of the rectangle is 54 cm what are the width and length of the rectangle?
width=9 length=18
What is the longest length a shadow cast of a 10 foot tall object?
In therory, infinitely long. In practice, the shadow will fade into dispersed light.
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.
In the morning I have as many feet as you I am gone in the after noon and I might have more feet than you at night what am I?
A shadow. The shadow that a person casts in the morning is the same length as the person, then it disappears in the afternoon, and can grow longer in size during the nighttime when the light source is low.
What is the length of the shadow of a person who is 4.75 feet tall the angel of the sun above the horizone is 27.5 degrees?
You are dealing with similar right angle triangles:the top of the shadow, the top of the person and the bottom of the person and shadow form one of themthe top of the shadow, the sun and the horizon form the other.Thus the angle from the top of the shadow to the top of the person is the same as the angle of the sun above the horizon.The trigonometric ratio tan (= opposite_side / adjacent_side) can be used to solve for the length of the shadow:tan angle = height_of_person / length_of_shadowtan 27.5o = 4.75ft / shadowshadow = 4.75ft / tan 27.5o ~= 9.1ft
If a nail is 50 millimeters in length what is its shadow length in millimeters?
Its shadow will be 50 millimeters in length, if you lay it down on a flat surface.
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.
How tall is a person that casts a 9 foot shadow?
Depends on the time of day (the angle of the sun). Think of the person as being at a right angle to the ground, and the shadow being the other side. The distance from the person's head to the end of the shadow is the hypotenuse. (a^2 + b^2= c^2) a= height of person, b= shadow. If you have the angle of the sun to the ground, you can use Sine/ Cosine to calculate the length.
What three things do length and position of a shadow changing depend on?
The length and position of a shadow depend on the angle of the light source, the distance between the object and the surface the shadow falls on, and the height of the object casting the shadow.
How does the length of a shadow change during the yearwhy does this happen?
The length of the shadow (on a flat, horizontal floor) depends on the height of the Sun. If the Sun is higher in the sky, the shadow will become shorter.
Does the length of a sun stick control the distance a shadow moves?
yes the length of the sun stick does control the distance the shadow moves
What will be the height of the shadow cast by a person standing near a 20 ft light post.The height of the person is 6 ftThe distance between man and pole is 10 ft?
It is zero: 0cm; 0mm A shadow has no height: length yes, but height no
A tree is twice as high as the length of the shadow it casts The distance from the tip of tree to the tip of the shadow is 8 feet What is the length of the shadow that the tree casts?
Since the tree is twice as high as the length of the shadow, we can set up the following equation: 2x = x + 8, where x is the length of the shadow. Solving the equation gives us x = 8 feet, so the length of the shadow that the tree casts is 8 feet.
What is the length of the rectangle if the perimeter is 54 cm and it's length is twice it's width?
Let its width be x:- 2(2x+x) = 54 => 4x+2x = 54 => 6x = 54 => x = 9 Therefore: width = 9 cm and length = 18 cm
