what is the equivalent decimal to this praction 5/45
Answers
Answer:
[tex]0.\overline{1}[/tex]
Step-by-step explanation:
The fraction reduces to 1/9. Since you're familiar with the decimal equivalents of fractions with denominators less than 10, you know this has the decimal equivalent:
1/9 = 0.11111111...(repeating)
_____
Even if you're not familiar with the equivalent of 1/9, you probably know that ...
1/3 = 0.33333...(repeating)
and
2/3 = 0.66666...(repeating)
Of course, 1/3 = 3/9, so dividing 0.333... by 3, we get 1/9 = 0.111....
_____
The attachment shows the long division. It gets boring quickly.
Final answer:
The equivalent decimal of the fraction 5/45 is approximately 0.1111
Explanation:
To find the equivalent decimal of the fraction 5/45, we can start by simplifying the fraction. Since both the numerator (5) and the denominator (45) are divisible by 5, we can reduce the fraction to 1/9.
To convert this simplified fraction into a decimal, we divide 1 by 9.
1 ÷ 9 = 0.111...
The decimal 0.111... means that the 1 repeats indefinitely, which is known as a repeating decimal.
If we want to convert this repeating decimal into an approximation with a specific number of decimal places, we could round it. For example, we could say 0.111... is approximately 0.111 when rounded to three decimal places.

Let n represent the position of a term in the sequence below.
8, 11, 14, 17, 20, 23,
Which algebraic expression can be used to find the nth term of the sequence
Answers
The algebraic expression can be used to find the nth term of the sequence is:
[tex]a_n = 5+3n[/tex]
Where, [tex]n\geq 1[/tex] and n is a positive whole number
Solution:
Given sequence is:
8, 11, 14, 17, 20, 23
Let us find the common difference between terms
11 - 8 = 3
14 - 11 = 3
17 - 14 = 3
20 - 17 = 3
23 - 20 = 3
Thus the common difference between successive term and previous term is constant
Thus this is a arithmetic sequence
The formula for nth term term of arithmetic sequence is given as:
[tex]a_n = a_1+(n-1)d[/tex]
Where,
[tex]a_n[/tex] is the nth term of sequence
[tex]a_1[/tex] is the first term of sequence
d is the common difference between terms
Here in this sequence, 8, 11, 14, 17, 20, 23
[tex]a_1 = 8\\\\d = 3[/tex]
Therefore,
[tex]a_n = 8+(n-1)3\\\\a_n = 8+3n -3\\\\a_n = 5+3n[/tex]
Where, [tex]n\geq 1[/tex] and n is a positive whole number
Thus algebraic expression can be used to find the nth term of the sequence is found

Identify all the sets to which the number belongs. Choose from Rational Number, Irrational number, whole number, and integer. 1.256...
A. Rational number
B. Irrational number
C.Integer, and rational number
D. Whole number, Integer, and rational number
Answers
Answer:
The number 1.256 is A)rational number.
Step-by-step explanation:
A whole number is a non-negative number without any digits behind the decimal. An integer is a set of negative and non negative numbers that don't have any digits behind the decimal.A number that can be shown as a fraction of two whole numbers is a rational number.And the numbers that are not rational are irrational numbers.Here, 1.256 is a fraction of whole numbers 1256 and 1000 , so it is a rational no.[tex]\frac{1256}{1000} =1.256[/tex]
But since it has digits behind the decimal it is neither a whole number, or an integer.The number 1.256... is a rational number because it can be expressed as a ratio of two integers. It is not an integer, whole number, or irrational number.
Explanation:The number 1.256 repeated is a rational number because it can be expressed as the ratio of two integers, which fits the definition of a rational number as ratios of integers such as 2/1, 3/4, and so on.
Even though the decimal representation may appear to continue forever, if the pattern of digits repeats indefinitely, it is still rational.
This number is not an integer, whole number, or irrational number, so it does not belong to those sets. An integer is a whole number without any fractional or decimal part, positive or negative, including zero.
Therefore, the correct option that defines the sets to which the number 1.256... belongs is Option A: Rational number.
A garden supply store sells two types of lawn mowers. The smaller mower costs $249.99 and the larger mower costs $329.99. If 30 total mowers were sold and the total sales for a given year was $8379.70, find how many of each type were sold.
Answers
19 small mowers and 11 large mowers are sold
Solution:
Let "a" be the number of small mowers sold
Let "b" be the number of large mowers sold
Cost of each small mower = $ 249.99
Cost of each large mower = $ 329.99
30 total mowers were sold
Therefore,
a + b = 30
a = 30 - b ------------- eqn 1
The total sales for a given year was $8379.70
Thus we frame a equation as:
number of small mowers sold x Cost of each small mower + number of large mowers sold x Cost of each large mower = 8379.70
[tex]a \times 249.99 + b \times 329.99 = 8379.70[/tex]
249.99a + 329.99b = 8379.70 ---------- eqn 2
Let us solve eqn 1 and eqn 2
Substitute eqn 1 in eqn 2
249.99(30 - b) + 329.99b = 8379.70
7499.7 - 249.99b + 329.99b = 8379.70
80b = 8379.70 - 7499.7
80b = 880
Divide both sides by 80
b = 11
Substitute b = 11 in eqn 1
a = 30 - 11
a = 19
Thus 19 small mowers and 11 large mowers are sold

Write a polynomial, P(x), in factored form given the following requirements.
Degree: 3
Zeros (roots) at (−2,0) with multiplicity 2 and (3,0) with multiplicity 1
P(x) passes through the point (2,80)
Answers
Answer:
The polynomial will be P(x) = - 5 (x + 2)²(x - 3)
Step-by-step explanation:
The degree of the polynomial P(x) is 3 and it has zeros at x = - 2 with multiplicity 2 and at x = 3 with multiplicity 1.
Therefore, (x + 2)² and (x - 3) are the factors of the equation.
Let the polynomial is
P(x) = a(x + 2)²(x - 3) ........... (1)
Now, the polynomial passes through the point (2,80).
So, from equation (1) we gat,
80 = a(4)²(-1)
⇒ a = - 5
Therefore, the polynomial will be P(x) = - 5 (x + 2)²(x - 3) (Answer)
The required polynomial is [tex]P(x) = - 5 (x + 2)^{2} (x - 3)[/tex]
Any polynomial have number of roots equal to its degree of polynomial.
Since, the degree of the polynomial P(x) is 3. it means that it has 3 roots.
it has zeros at x = - 2 with multiplicity 2, it means that factor (x - 2) have power 2 and at x = 3 with multiplicity 1 means that factor (x - 3) have power of 1 .
Thus, [tex](x + 2)^{2}[/tex] and (x - 3) are the factors of the equation.
Let us consider the polynomial is [tex]P(x) = k(x + 2)^{2} (x - 3) .[/tex]
Since, the polynomial passes through the point (2,80).
So, substituting point (2, 80) in above polynomial equation.
We get, [tex]80 = a(4)^{2} (-1)[/tex]
a = - 5
Therefore, the polynomial is [tex]P(x) = -5(x + 2)^{2} (x - 3) .[/tex]

A rectangle is eight inches and diagonal is ten
inches. What's the width of the rectangle?
Answers
Answer: Its width is 6inches.
Step-by-step explanation:
The given information can be used to construct a right angled triangle. Now applying the Pythagoras theorem,
10^2 = W^2 + 8^2
where w represents the width.
100 = w^2 + 64
100 - 64 = w^2
36 = w^2
find the square root of both sides,
6 = w
Therefore, w = 6 inches
Thus the width of the rectangle is 6 inches.
Pirate Jack has an equal number of gold and silver coins. If Pirate Jack splits all of his coins into 7 equal piles for his parrots, he has 4 coins left. Or, if he splits all of his coins into 11 equal piles for his shipmates, he has 4 coins left. Assuming every pile has at least 1 coin, what is the least possible number of coins Pirate Jack has?
Answers
Answer:
The least possible number of coins that Pirate Jack has is 77.
Step-by-step explanation:
i) let the number of coins in the piles for the parrots be x.
ii) therefore we can say that the total number of coins be 7x + 4
iii) let the number of coins in the piles for for the pirates be y.
iv) therefore we can say that the total number of coins be 11y + 4
v) therefore we can say that 7x + 4 = 11y + 4
vi) therefore 7x = 11y
vii) therefore the least possible number of coins that Pirate Jack has is equal to the LCM of 11 and 7 which is 77.
viii) x = 11 and y = 7
Answer:
158 coins
Step-by-step explanation:
Jack's number has to be an even number, because he can split his gold and silver coins evenly.
77 is the LCM of 11 and 7 and add 4 (the remainder) to get 81.
But it has to be an even number since he can split his coins evenly.
You can then do 77 times 2, and add 4 to get 158, which is the answer.
