(A) 6/20 = x/2000
Step-by-step explanation:
To complete your questions, the missing parts are shown below
Sample 1 Sample 2 total
Country 5 3 8
Pop 4 3 7
Classical 3 5 8
Jazz 2 4 6
Rock 6 5 11
Total 20 20 40
The proportion that would predict the number of jazz songs that Mr. McElroy has stored on his MP3 player is given by 6/20
Hence, our required proportion would be
6/20 =x/2000
We cross multiply
20x = 2000 x 6
20x = 12000
Divide both sides by 20
X = 12000/20
X = 600
Hence, our required proportion would be
6/20 = x/2000
Given:
In a right angle triangle,
Hypotenuse = 25 cm
Base = x
Angle between base and hypotenuse = 18 degrees.
To find:
The value of x.
Solution:
In a right angle triangle,

In the given right triangle,




Round the answer to the nearest hundredth (two decimal).

Therefore, the value of x is about 23.78 cm.
Answer:

Step-by-step explanation:
The polynomial given for simplification is:

Now, we combine like terms using the commutative property of addition.
The commutative property of addition states that:

So, the order can be shuffled when we add terms.
The terms containing 't' are grouped together and the constant terms are grouped together. This gives,

Now, we group them using associative property and converse of distributive property as:

Simplifying the above expression, we get:

Therefore, the simplified form is 
Answer:
x = -26.67 (this is rounded the real answer is 26.6666...)
Step-by-step explanation:
180 - (46 + 36) = 82 (the measure of the last angle)
82 = (2 - 3x)
(subtract two from both sides)
80 = (-3x)
(divide both sides by -3)
-26.67=x
