How many distinct products can be formed using two different integers from the given set: {–6, –5, –4, –3, –2, –1, 0, 1, 2, 3, 4, 5}?
Number of distinct products that can be formed is 144
PermutationSince we need to multiply two different integers to be selected from the set which contains a total of 12 integers. This is a permutation problem since we require distinct integers.
Now, for the first integer to be selected for the product, since we have 12 integers, it is to be arranged in 1 way. So, the permutation is ¹²P₁ = 12
For the second integer, we also have 12 integers to choose from to be arranged in 1 way. So, the permutation is ¹²P₁ = 12.
Number of distinct products
So, the number of distinct products that can be formed from these two integers are ¹²P₁ × ¹²P₁ = 12 × 12 = 144
So, the number of distinct products that can be formed is 144

One way to make it easier to multiply, pick a number from a multiplication problem. Then, add the amount of times of the other number.
Example:
6 x 8 = ?
8 = Chosen Number
So, add 8, 6 times.
8 + 8 + 8 + 8 + 8 + 8 = ?
? = 48
Which, 6 x 8 does equal 48.

The area of a rectangular painting is 6600 cm?.
If the width of the painting is 75 cm, what is its length?
Answer:
length = 88 cm
Step-by-step explanation:
Area of a rectangle = width × length
Given:
Area = 6600 cm²width = 75 cmSubstituting these values into the equation:

Answer:
(- 21, - 13 )
Step-by-step explanation:
- 3y + x = 18 → (1)
x = 2y + 5 → (2)
substitute x = 2y + 5 into (1)
- 3y + 2y + 5 = 18
- y + 5 = 18 ( subtract 5 from both sides )
- y = 13 ( multiply both sides by - 1 )
y = 13
substitute y = - 13 into (2)
x = 2(- 13) + 5 = - 26 + 5 = - 21
solution is (- 21, - 13 )

Mr. Smith earned $600 last year. His total deductions amounted to 10%
of his earnings. What was his take-home salary?
Answer:
540
Step-by-step explanation:
10% of 600 is 60, 600-60 is 540
The 10% of $600 will be $60 therefore, the net salary that Mr. Smith will take home will be $540.
What is the percentage?The percentage is defined as a given amount in every hundred. It is a fraction with 100 as the denominator percentage is represented by the one symbol %.
The percentage is also called the indicating hundredths. Thus, 2% is two-hundredth, which means 2%=2/100=0.02.
As per the given,
Base salary = $600
10% of $600 = (10/100) x 600 = $60
Net salary = $600 - $60 = $540
Hence "The 10% of $600 will be $60 therefore, the net salary that Mr. Smith will take home will be $540.".

Answer:
500 grams is 20 percent of 2.5 kg
Step-by-step explanation:
500*100 = 50,000
50,000/2500=20
500 g is the 20% of 2.5kg.
What is percentage ?
The percentage is a ratio of number as a fraction over 100.
According to the given question
we have to find the percentage of 2.5 kg
since, 500g = [tex]\frac{500}{1000}[/tex] = 0.5kg
The percentage of a quantity x is given by
percentage = [tex]\frac{Q}{value}[/tex]×100
Substitute, Q = 0.5kg and value = 2.5kg in the above formula
⇒ percentage = [tex]\frac{0.5}{2.5}[/tex]× 100 = 20%
Hence, 500g is the 20% 0f 2.5g.

Write 24.775 in fractional notation.
Answer:
24.775 / 1 or 24775 / 1000
Step-by-step explanation:
To get rid of the decimal point in the numerator, we count the numbers after the decimal in 24.775, and multiply the numerator and denominator by 10 if it is 1 number, 100 if it is 2 numbers, 1000 if it is 3 numbers, and so on.
Therefore, in this case we multiply the numerator and denominator by 1000 to get the following fraction:
