Answer:
A statement, also known as an axiom, which is taken to be true without proof. Postulates are the basic structure from which lemmas and theorems are derived.
Step-by-step explanation:
The Addition Postulate: If you have one apple and Sally has one apple, when you both add the same quantity to your existing number of apples, you'll still have the same number of apples. Using algebra, the postulate states:
If x = y, then x + 4 = y + 4
The Subtraction Postulate: If you have ten apples and Sally has ten apples, when you both subtract the same quantity of apples from your existing number of apples, you'll still have the same number of apples.
If x = y, then x - 3 = y - 3
Without being repetitive, these same principles apply to both multiplication and division.
The Multiplication Postulate: If x = y, then x * 3 = y * 3
The Division Postulate: If x = y, then x / 7 = y / 7
|x+y| = |-8+(-13)| = |-8-13| = |-21| = 21
Answer:
2.5 square feet
Step-by-step explanation:
The area (A) of a regular hexagon in terms of its side length (s) is ...
A = (3/2)(√3)s²
The side length in feet is ...
(30 cm)×(1 ft)/(30.48 cm) = s = 30/30.48 ft = 125/127 ft
Then the area in square feet is ...
A = (3/2)√3(125/127 ft)² ≈ 2.517 ft²
The approximate area of the hexagon is 2.5 square feet.

<em>Comment on the question</em>
There is nothing in this problem statement that relates the hexagon to the window area.
The fourth one should be the correct answer
Answer:
The speed of car in miles per minute is 
miles per minute and
The speed of car in mile per hour is 40 miles per hour,
Step-by-step explanation:
Given as :
The distance cover by car = 2 
= 
miles
The Time taken by car to cover distance = 3 
min = 
min
The speed o car in miles per minute = S miles/min
So, Speed = 
Or, S = 
mie per min
∴ S = miles per minute
Now, Let The speed of car in miles per hour = x miles/h
So, Time in hour = × 
= 
hours
So , Speed =
Or, x = 
miles per hours
Or, x = 40 miles per hours
Hence The speed of car in miles per minute is miles per minute and the speed of car in mile per hour is 40 miles per hour, answer
