_____
A mixed number is converted to an improper fraction by
.. a +b/c = (ac +b)/c
Of course, dividing by a fraction is the same as multiplying by its inverse.
.. (a/b) / (c/d) = (a/b) * (d/c)
Answer:
(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
Answer:
11. the first one 12. the last one
Step-by-step explanation:
Answer:
The real numbers include all the rational numbers, such as the integer −5 and the fraction 4/3, and all the irrational numbers, such as 2 (1.41421356..., the square root of 2, an irrational algebraic number).
Answer
D. 3m - 4/3 -2/m
<u>Explanation</u>
(9m²-4m-6) ÷ 3m = 9m²/3m - 4m/3m - 6/3m
Carry out the division, each term is divided by 3m.
9m²/3m = 3m
- 4m/3m = -4/3
- 6/3m = - 2/m
Finally you will get,
<em>3m - 4/3 -2/m</em>
