Answer:
rational
Step-by-step explanation:
a rational number is a number that can be expressed as the ratio of two numbers. 33 to 3 is a ratio, so this works.
it is not a whole number because it is not a counting number
it is also not a natural number because it is not a whole number
Answer:
3(2 + 9)
Step-by-step explanation:
The numbers 6 and 27 can be written as factored as
6 = 2 * 3
27 = 3 * 3 * 3
The both have one factor of 3 in common.
The greatest common factor (the GCF) of 6 and 27 is 3.
Now we factor out 3. To do that, we divide both 6 and 27 by 3.
6/3 = 2
27/3 = 9
We see that
6 + 27 = 3 * 2 + 3 * 9,
and the common factor of 3 is in both multiplications.
Finally, we factor out the 3, leaving the results of the divisions inside the parentheses.
6 + 27 = 3 * 2 + 3 * 9 = 3(2 + 9)
Answer: 3(2 + 9)
Answer:
D
Step-by-step explanation:
Suppose you buy the first for $30 and next for $20
The 2nd item ($20) will be given 60% discount.
<em>What is 60% of 20?</em>
<em>60/100 = 0.6 * 20 = 12</em>
<em />
So, that is off for $12, final price of 2nd item would be:
20 - 12 = $8
Total Cost (WITHOUT DISCOUNT) = 30 + 20 = 50
Total Cost (with discount) = 30 + 8 = 38
What is the percentage decrease?? It will be the DIFFERENCE (50 - 38 = 12) divided by the original price (50).
Percentage Reduction = 12/50 = 0.24
0.24 In percentage is 0.24 * 100 = 24%
D is the correct answer.
