The decimal expansion of 1/9 is 0.1111..., which continues indefinitely. This is achieved by dividing the numerator (1) by the denominator (9). The decimal expansion of a fraction is the expression of that fraction in base 10 notation.

The decimal expansion of the fraction 1/9 is 0.1111.... This is achieved by dividing the numerator (1) by the denominator (9). The process of long division would show you that 9 doesn't go into 1, so you add a decimal point and a zero, making the dividend 10. 9 goes into 10 once, so you put a 1 in the quotient above the line. This process repeats itself due to the nature of the divisor 9 and the decimal 0.1111... continues indefinitely.

It's important to note that the decimal expansion of a fraction is an expression of that fraction in base 10 notation. In other words, it is the fraction expressed as a decimal.

For some numbers, this can be a finite number of digits long, and for others, like 1/9, it can be infinitely repeating.

Write f(x) above g(x), as shown below:

 f(x)=2x^2 + 3

- g(x) = x^2 - 7

---------------------   Next, combine the givens in three columns:

(f-g)(x) = x^2 + 10 (answer)

The arithmetic operation of the functions f(x) and g(x) is x² + 10 if  arithmetic operation is (f-g)(x) option (D) is correct.

It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.

It is given that:

f(x) = 2x² + 3

g(x) = x² - 7

To find the (f-g)(x)

(f-g)(x) = f(x) - g(x)

Plug the function f(x) and g(x):

The above expression is representing an arithmetic operation of the functions:

(f-g)(x) = f(x) - g(x) = (2x² + 3) - (x² - 7)

(f-g)(x) = 2x² + 3 - x² + 7

(f-g)(x) = x² + 10

Thus, the arithmetic operation of the functions f(x) and g(x) is x² + 10 if  arithmetic operation is (f-g)(x) option (D) is correct.

Answer:

75

Step-by-step explanation:

Number of foul shots made by the girl first time = 12

Number of shots missed by the girl first time = 8

Total number of shots played first time = 12 + 8 = 20

Let the number of foul shots made by the girl second time be x

The total number of shots played by the girl second time = 125

Let's set up a proportion,

[tex]\frac{Number of foul shots made by the girl first time}{Total number of shots played first time}[/tex] = [tex]\frac{number of foul shots made by the girl second time}{total number of shots played by the girl second time}[/tex]

=> [tex]\frac{12}{20} = \frac{x}{125}[/tex]

Flip the sides of the equation

[tex]\frac{x}{125} = \frac{12}{20}[/tex]

Multiplying both the sides by 125

[tex]\frac{x}{125}*125 = \frac{12}{20}*125[/tex]

Cancelling out the 125's on the top and bottom from the left side

x = [tex]\frac{12}{20}*125[/tex]

=> x =  [tex]\frac{1500}{20}[/tex]

=> x = 75

Number of foul shots made by the girl if she played 125 foul shots = 75

To find out how many shots the girl made, set up a proportion using the ratio of shots made to shots missed. The girl made 187 shots.

To find out how many shots the girl made, we can set up a proportion using the ratio of shots made to shots missed. The ratio is 12:8. Let's assume the number of shots made is x. We can create the proportion: 12/8 = x/125. Cross-multiplying gives us 8x = 12 * 125. Solving for x gives us x = (12 * 125) / 8. Evaluating this expression gives us x = 187.5. Since we can't have a fraction of a shot, we round down to the nearest whole number. Therefore, the girl made 187 shots.

Given that the revenue for each jumbo biscuit sold is $1

Given that the cost to make each jumbo biscuit is $0.20

Then profit on each jumbo biscuit =$1 - $0.20 = $0.80

Since positive profit occurs so producing jubo biscuit is good idea.

Given that the revenue from each regular biscuit is sold at $0.65

Given that the cost to make each regular biscuit is $0.15

Then profit on each regular biscuit =$0.65 - $0.15 = $0.50

Since positive profit occurs so producing regular biscuit is good idea.

As in both business, we are getting positive profit. Infact more profit on jumbo biscuits so YES, bakery can produce 10 regular biscuits and 55 jumbo biscuits.

The bakery can produce 10 regular biscuits and 55 jumbo biscuits. This conclusion is based on calculations showing that the revenue generated from selling these biscuits is higher than the cost to produce them. There are no clear limitations violated.

The bakery can indeed produce 10 regular biscuits and 55 jumbo biscuits, as long as it accounts for the cost associated with making each biscuit. We can calculate this through simple multiplication. The cost to make 10 regular biscuits would be 10 * $0.15 = $1.50, and the cost to make 55 jumbo biscuits would be 55 * $0.20 = $11.00.

The revenue from selling 10 regular biscuits would be 10 * $0.65 = $6.50, and the revenue from selling 55 jumbo biscuits would be 55 * $1 = $55. Hence, the total cost of producing these biscuits is $1.50 (for regular biscuits) + $11 (for jumbo biscuits) = $12.50, while the total revenue generated is $6.50 (from regular biscuits) + $55 (from jumbo biscuits) = $61.50.

The revenue generated ($61.50) is clearly higher than the cost of production ($12.50), so it would be financially feasible for the bakery to produce these biscuits. There are no apparent limitations violated.

Your answer is A. The sum of x and y is a rational number .

Answer:

A) The sum of x and y is a rational number.

Step-by-step explanation:

We will first prove that the given values of x and y are rational and then we will prove the fact that the sum of two rational numbers is a rational number.

A rational number is a number which is in the form [tex]\frac{p}{q}[/tex], where p and q are integers and q ≠ 0.

We can write - 5 as [tex]\frac{-5}{1}[/tex] and clearly 1 ≠ 0.

So, x = -5 is a rational number.

Similarly, y = -4 is also a rational number.

For the second part of the proof, consider any two rational numbers [tex]\frac{p}{q}[/tex] and [tex]\frac{r}{s}[/tex].

Now,

[tex]\frac{p}{q} +\frac{r}{s} =\frac{ps+rq}{qs}[/tex]

Since p, q, r and s are integers, ps + rq is also an integer.

Moreover, since q ≠ 0 and s ≠ 0, qs ≠ 0.

Therefore, [tex]\frac{ps+rq}{qs}[/tex] is also a rational number.

Hence, sum of two rational numbers is also a rational number.

Since x = -5 and y = -4 are rational numbers, x + y = (-5) + (-4) = -9 is also a rational number.

What creates the convection current inside Earth?

A. Rising and sinking of material

Answer: A. Rising and sinking of material.

Step-by-step explanation:

Convection currents are caused by the cooling of material as it rises up, which leads to the same material to sink. This material then warms as it sinks to rise again. This is why we call them convection currents. Because they both rise, and sink, in a circular motion we call the convection current.

Patrick initially has 600 meters of yarn. After using some to make a hat, he only has 351.1 meters of yarn left, which is not enough to make a scarf that requires 354.03 meters.

To answer this question, we have to perform a subtraction operation on the total lengths of yarn. Initially, Patrick has a 600-meter skein of yarn. After making a hat, he uses 248.9 meters of yarn. To find out how much yarn is left, we subtract the amount used from the total: 600 - 248.9 = 351.1 meters. You then need to check if 351.1 meters are enough to make a scarf that consumes 354.03 meters of yarn. In this case, we can see that Patrick does not have enough yarn left to make the scarf because 351.1 meters is less than 354.03 meters.

Answer:

the two integers are 17 and 18

Step-by-step explanation:

Let x represent the smaller integer. Then x+1 is the larger. The problem statement tells us

... 2 × larger = -15 + 3 × smaller

... 2(x+1) = -15 + 3x . . . substitute variable expressions for 'larger' and 'smaller'

... 2x +2 = 3x -15 . . . . . eliminate parentheses

... 17 = x . . . . . . . . . . . . .add 15-2x

The smaller integer is 17, so the larger is 18.

_____

Check

2×18 = 36 = 3×17 -15 = 51-15

Let's take the first number as 'x' ( This would be the smaller number )

Let's take the second number as 'x+1' ( This would be the larger number )

I have taken x and x+1 because both these numbers are consecutive.

Twice the larger number :-

... 2 ( x + 1 )

... 2x + 2

15 less than thrice the smaller number :-

... 3x - 15

The question states that these both values are equal. Hence,

... 2x + 2 = 3x - 15

... 2 + 15 = 3x - 2x

... 17 = x

The value of 'x' is 17

( The smaller number is 17 )

Larger number :-

... x + 1

... 17 + 1

... 18

Hence, the numbers are 17 and 18.

Answer:

Step-by-step explanation:

Answer is 72 cm2.For step by step explanation please find the attachment.

Remark

You have to read this carefully to know what way to write it.

One way you could write it would be

20 * x = 18 where x is  the fraction. Now all you need do is divide.

Divide both sides by 20

20/20 * x = 18/20

[tex]\text{x = } \dfrac{18}{20}[/tex]

But you should reduce this fraction. The way to do that is to factor 18 and 20 into primes.

18: 2 * 3 * 3

20: 2 * 2 *5

Cancel out the Highest common factor or 2.

You are left with

[tex]\text{x = } \dfrac{18}{20} =\dfrac{2*3*3}{2*2*5}=\dfrac{3*3}{2*5} = \dfrac{9}{10}[/tex] <<<< Answer

★ What fraction of 20 is 18?

In questions like these, when you see the word "of", it is usually used for the denominator. In your question, it says "of 20". That means the denominator will be 20.

Here is your current fraction:

[tex]\frac{x}{20}[/tex]

After that phrase, it says "is 18". The word "of" is used for the numerator. That means the numerator is 18.

Here is your fraction:

[tex]\frac{18}{20}[/tex]

You have your complete fraction, but it can be simplified. Both numbers are even(numbers that end with 2, 4, 6, 8, or 0) and every even number is divisible by 2. You can just divide both numbers by 2.

[tex]\frac{18 \div 2}{20 \div 2} = \frac{9}{10}[/tex]

You have your simplified fraction, which is [tex]\frac{9}{10}[/tex], and it cannot be simplified any further.

Your answer is [tex]\frac{18}{20}[/tex] which becomes [tex]\frac{9}{10}[/tex] when simplified.

We are given a triangle with dimensions of the three sides as :

first side: 10x+3x²-8 feet

second side: 12x feet

third side: (15x+4) feet

Now perimeter of triangle is given by:

Perimeter = sum of three sides

So adding the three sides:

Perimeter = 10x+3x²-8 + 12x +15x+4

combining like terms and simplifying:

Perimeter = 3x²+37x-4

Answer: The perimeter of park will be (3x²+37x-4) feet.

So, just divide:

52.50 / 6 = 8.75

This means that she earns $8.75 an hour.

If this is her hourly salary, then multiply 8.75 x 11

8.75 x 11 = 96.25

So, if Paula works for 11 hours,  she will earn $96.25!

Remark

I think you can only do this either as a 2 step question or as a proportion. The easiest way is the proportion.

6 hours / 52.50 = 11/x      Cross multiply

6*x = 52.50 * 11                Combine the factors on the right

6x =  577.5                       Divide both sides by 6

Step-by-step explanation:

Let the gradient be calculated as follows:

slope = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

         = [tex]\frac{-7-(-3)}{6-(-6)}\\ = -\frac{1}{3}[/tex]

to find the equation passing through the point we calculate as follows:

[tex]- 3= \frac{1}{3} (-6) + b\\ -1 = b[/tex]

Therefore, the equation of the line is:

[tex]y = \frac{1}{3}x - 1[/tex]

An equation of this graphed line in slope-intercept form is [tex]y=-\frac{1}{3} x-5[/tex].

In Mathematics and Geometry, the point-slope form of a straight line can be calculated by using the following mathematical equation (formula):

y - y₁ = m(x - x₁)

Where:

First of all, we would determine the slope of this line;

Slope (m) = (y₂ - y₁)/(x₂ - x₁)

Slope (m) = (-7 - (-3))/(6 - (-6))

Slope (m) = -1/3.

At data point (6, -7) and a slope of -1/3, a linear equation for this line can be calculated by using the point-slope form as follows:

y - y₁ = m(x - x₁)

[tex]y-(-7)=-\frac{1}{3} (x-6)\\\\y+7=-\frac{1}{3} (x-6)\\\\y=-\frac{1}{3} x-5[/tex]
