<h3>Answer:</h3>
15.56 inches
<h3>Explanation:</h3>
Let L represent the leg length. Then the Pythagorean theorem tells you ...
... 22² = L² + L² . . . . the square of the hypotenuse is the sum of the squares of the other two sides
... 484 = 2L² . . . . . . . simplify
... 242 = L² . . . . . . . . divide by 2; next, take the square root
... √242 = L ≈ 15.56 . . . . inches
_____
<em>Comment on this problem in general</em>
For a hypotenuse of length H, the above equation becomes ...
... H² = L² +L² = 2L²
... H²/2 = L² . . . . . divide by 2
... H/√2 = L . . . . . take the square root (<em>general solution for isosceles right triangles</em>)
For your problem, this is ...
... (22 in)/1.414214 = L = 15.556 in
Answer:
5:4
Explanation:
The scale factor would be 15:12 because the sides are corresponding. This ratio simplifies to 5:4 when divided by 3.
Answer:
Step-by-step explanation:
Given
Required
Write an equivalent expression
To do this, we simply write as a product of two factors.
Express 4b as 2 * 2b
Express 2m as 2 * m
Factor 2 out of the expression:
Hence:
An equivalent expression is:
To solve this problem you must apply the proccedure shown below:
1- You have that the area of the living room is:
A=lw (Area of the rectangle); where l is the lengt and w is the width.
A=(21 feet)(15 feet)
A=315 feet²
2- The cost is:
Cost=315 feet²x$9
Cost=$2835
The answer is: He will need 315 feet² and it will cost $2835

<h3>What is Internal Validity? </h3>
Internal validity can be described as the extent that a particular study can bring about the establishment of a trustworthy cause-and-effect relationship which can be set between the treatment as well as the outcome.
In conclusion, Internal validity let us understand that a study can makes it possible to eliminate alternative explanations as regards finding, hence The types of validity that were not established in this study is internal validity and the Reasonably not met are: external, construct, statistical.
