The fraction is 47/200. The decimal is 0.235.

A percentage can be written in a fraction form by putting 100 on the denominator. For example, the fraction corresponding to x % is x/100.

For converting a percentage into a decimal first it should be converted into fractions as fractions can only be converted into decimal.

For example, the decimal for the fraction 50% is 0.5, which is given by writing 50% as 50/100 = 0.5 after putting decimal on 2 places left to 50.

So here the given percentage is 23.5%.

The corresponding fraction is 23.5/100 = 235/1000 = 47/200 after eliminating the decimal on the numerator and simplifying.

Now the corresponding decimal is, 0.235. Since 1000 is in the denominator for 235/1000, we can simply find the decimal by putting decimal point on 3 places left to 235.

The Equation of perpendicular bisector line l is found to be [tex]y = 2x+ 11[/tex]

Given Line XY is formed by points  X(-9, -7) and Y(-3,5) therefore, it passes through these two respective points.

Let the slope of this line be n

The Slope of line passing through X and Y points is given by

n = [tex](y_{2} - y_{1} )/(x_{2} -x_{1} )[/tex]

⇒ n = {5 - (-7) }/ {(-3) - |(-9)}

⇒ n = 12/6

⇒ n = 2               (equation 1 )

Given that line l is perpendicular bisector of XY

Let the slope of l  = m

We know that the product of the slopes of any two perpendicular lines is -1

Therefore, n x m = -1

⇒ m = -1 \ n

putting the value of n from the above equation 1 we get

⇒ m = - 1/2

Additionally, because l is the perpendicular bisector hence it goes through the mid point of the line XY

Mid point of two lines = [tex](x_{2} + x_{1} )/2[/tex] and [tex](y_{2} + y_{1} )/2[/tex]

Mid point of XY = [tex]\frac{-9 + (-3)}{2}[/tex] and [tex]\frac{-7 + (5)}{2}[/tex]

                          = (-6, -1)

The equation of perpendicular bisector l is given my the following formula:

[tex]y = nx + c[/tex]

here we have n = slope of line

we have n = 2 from equation 1

∴ y = 2x + c (equation 2)

Also equation (2) is satisfied by the point (-6,-1)

Hence we can express it as:

-1 = 2(-6) + c

⇒ c = 11

Therefore the required equation of perpendicular bisector l is

[tex]y = 2x + 11[/tex]

If a trader is given a 15 percent discount on the factory price of certain goods, the factory price being ¢45000000, then

(I) The discount amount will be ¢6750000

(II) The final amount that the trader will have to pay to buy the goods will be ¢38250000.  

As per the question statement, a trader is given 15 Percent discount on goods bought from a factory and the original price of the item bought from the factory is ¢45000000.

We are required to calculate the discount amount, and the final amount that the trader will have to pay to buy the goods.

To solve this question, we simply need to calculate 15 percent of 45000000, and then subtract the calculated discount amount from ¢45000000.

Therefore, 15 percent of ¢45000000 = ¢[(15/100) * 45000000]

                                                   = ¢(15 * 450000)

                                                   = ¢6750000

That is, on 15 percent discount on the factory price of certain goods, the factory price being ¢45000000, the discount amount is ¢6750000.

And, considering the discount of ¢6750000 on the factory price of ¢45000000, the final amount that the trader will have to pay to buy the goods = ¢(45000000 - 6750000)

           = ¢38250000.

r = - 8

Step-by-step explanation:

calculate the slope m using the slope formula , then equate to 3

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

with (x₁, y₁ ) = (- 5, r ) and (x₂, y₂ ) = (2, 13 )

m = [tex]\frac{13-r}{2-(-5)}[/tex] = [tex]\frac{13-r}{2+5}[/tex] = [tex]\frac{13-r}{7}[/tex]

then equating gives

[tex]\frac{13-r}{7}[/tex] = 3 ( multiply both sides by 7 )

13 - r = 21 ( subtract 13 from both sides )

- r = 8 ( multiply both sides by - 1 )

After the discount the net price is $7053.75 and the trade discount is 35.875% .

The term discount designates a sum or a percentage subtracted from an item's usual selling price.

The given marked price of the article is 11000

Price after first discount of 5% = 11000 - 5% of 11000 = 10450

Price after second discount of 10% = 10450 - 10% of 10450 = 9405

Price after third discount of 25% = 9405 - 25% of 9405 = 7053.75

Therefore the net price is 7053.75.

Therefore the trade discount is = ( 11000 - 7053.75 ) ÷ 11000 = 0.35875

Trade discount percentage = 35.875%

Hence after the discount the net price is $7053.75 and the trade discount is 35.875% .

Answer:

[tex]3x + y = 3 \\ 3 = x - y \\ 3 = x[/tex]

Answer:

y = -3x - 4

Step-by-step explanation:

We are given the equation 3x + y = 3, and we want to find an equation of the line that is parallel to 3x + y = 3.

This same line also passes through the point (1, -7).

Parallel lines have the same slopes. This means that we'll first need to find the slope of 3x + y = 3.

The equation is written in standard form, which is ax+by=c, where a, b, and c are free integer coefficients, but a and b cannot be 0. a is usually non-negative as well.

There is a shortcut into finding the slope when the equation is in standard form; the slope of the line is -a/b, where a is the coefficient in front of x and b is the coefficient in front of y).

The coefficient in front of x is 3, and 1 in front of y.

Substitute 3 as a, and 1 as b in -a/b. Don't forget about the - in front of a!

-3/1 = -3

This means the slope of the line is -3.

It is also the slope of the line parallel to it.

We can write the equation of the line we are trying to solve for in standard form, too. However, we could also write it in slope-intercept form.

Slope-intercept form is given as y=mx+b, where m is the slope and b is the y intercept.

As we are already given the slope, we can immediately plug that into the formula.

Replace m with -3.

y = -3x + b

Now we need to find b.

As the equation passes through the point (1, -7), we can use its values to help solve for b.

Substitute 1 as x and -7 as y.

-7 = -3(1) + b

Multiply.

-7 = -3 + b

Add -3 to both sides

-4 = b

Substitute -4 as b into the equation

y = -3x - 4
