Height of another tree that cast a shadow which is 20ft long is 5 feet approximately
<h3><u>Solution:</u></h3>
Given that tree with a height of 4 ft casts a shadow 15ft long on the ground
Another tree that cast a shadow which is 20ft long
<em><u>To find: height of another tree</u></em>
We can solve this by setting up a ratio comparing the height of the tree to the height of the another tree and shadow of the tree to the shadow of the another tree

Let us assume,
Height of tree = 
Length of shadow of tree = 
Height of another tree = 
Length of shadow of another tree = 
Set up a proportion comparing the height of each object to the length of the shadow,


Substituting the values we get,

So the height of another tree is 5 feet approximately
1. 8(-5/6) = (-5/6)8 illustrates the commutative property of multiplication.
2. 5.4 + 3 = 3 + 5.4 illustrates the commutative property of addition.
<h3>What is the Commutative Property of Multiplication?</h3>
The commutative property of multiplication states that the arrangement of change of numbers that you want to multiply does not change what you would get as the product.
For example, a × b = b × a.
In the same vein, 8(-5/6) = (-5/6)8 illustrates the commutative property of multiplication.
<h3>What is the Commutative Property of Addition?</h3>
The commutative property of addition also states that the order or arrangement of addends will not change the sum you would get.
For example, 3 + 2 = 2 + 3.
Therefore, the statement, 5.4 + 3 = 3 + 5.4 illustrates the commutative property of addition.

Do Pythagorean Theorem because a rectangle divided in diagonals form right triangles
A^2+b^2=C^2
Plug in the correct numbers and solve
A and B can be switched around but C is always the longest diagonal side which is called the hypotenuse not the Adjacent sides that form a right angle
So with correct solving you should get 5.
Answer:

Step-by-step explanation:
We need to get m on one side all by itself. To achieve this, let's subtract both sides by 1.2 to get
