hi can someone help me with this proof?

Step-by-step explanation:

I think it's wrongly labelled

but lemme adjust it and get you back on track

this is a quadrilateral which angles sum upto 360°.

this hold when <D=84°,<N=74° <M=82 and <L=3x+20

84+74+82+3x+20=360

3x+260=360

3x=100

x=100/3

x=33. 3°

[tex]8x+5y=-17[/tex] when y is -5

Substitute for y with given value:

[tex]8x+5(-5)=-17[/tex]

[tex]8x-25=-17[/tex]

Add 25 to both sides:

[tex]8x-25+25=-17+25[/tex]

[tex]8x=8[/tex]

Divide both sides by 8:

[tex]\dfrac{8x}{8} =\dfrac{8}{8}[/tex]

Answer:

254.34 in^2

Step-by-step explanation:

To calculate the Area of Circle is πr^2

r is the radius of the circle

In this problem, the diameter is given which is 18 in. To find the radius you have to divide the diameter by 2.

18/2 = 9 in is our radius

Area of Circle = π9^2

                       = 3.14*81

                       = 254.34 in^2                    

The annual salary will be 49750

Gross salary would be the total amount of compensation that an employer or business pays an employee during their employment. The Cost of Company, as well as CTC, on the other hand, would represent the overall compensation of employees. The CTC seems to be an employee's gross pay, but their net compensation is how much they actually take home.

Now, According to the question:

Let x be the annual salary.

Then 10% of x+250 equates 0.1(x+250).

Thus, the bonus equates $5000, then we will get the equation:

0.1(250 + x) = 5000

Solving for 'x' we get:

250 + x = [tex]\frac{5000}{0.1}[/tex]

250 + x = 50000

x = 50000 - 250

x = 49750

CTC and gross salary are sometimes confused. But there is a distinction among the two. Before taxes, Employee Provident Fund (EPF) contributions, and gratuities deducted from the CTC, the amount paid to the employee would be known as their gross salary.

The complete question is this:

The smallest amount that Byron could have converted is £73.44.

An exchange rate is the rate at which one currency can be exchanged for another currency. It is the value of one country's currency against another country's currency. Exchange rates fluctuate based on supply and demand for a particular currency, as well as economic and political factors.

Exchange rates are typically quoted as the value of one currency in terms of another currency. For example, an exchange rate of 1.2 US dollars (USD) to 1 Euro (EUR) means that 1 EUR can be exchanged for 1.2 USD.

There are two types of exchange rates, Floating and Fixed exchange rate.

According to question :-

To determine the smallest amount that Byron could have converted, we can use the exchange rate from shop A, which is €47.20 for £40.

If we divide the amount of euros he received (€68.44) by the exchange rate (€47.20 for £40), we get:

€68.44 ÷ €47.20/£40 = £73.44

15.2 ≈ c

The distance of the straight line from the starting  point by the is  is 15.2 miles.

The distance between a point and a line is the shortest distance between them.

It states that if a triangle is right-angled (90 degrees), then the square of hypotenuse is equals to the  sum of the squares of the other two sides.

If ΔOAB is a right angled triangle, right angle at A

then the Pythagoras equation will be

[tex]OB^{2} =AB^{2} +OA^{2}[/tex]      

(where OB, OA and AB are the length of the sides of triangle OAB)

According to the question

We have to find ,the distance of straight line from the starting point.

From, the provided figure we can conclude that OB is the straight line whose distance to be find

In ΔOAB, we have

[tex]OB^{2} =OA^{2} +AB^{2}[/tex]                              (By Pythagoras theorem)

[tex]OB^{2} =14^{2} +6^{2}[/tex]

The ordered pair for the function y = -(x/3) + 2 is (-3, 3), (0, 2), (3, 2) and (6, 0)

An equation is used to show the relationship between numbers and variables.

The standard form of a linear equation graph is:

y = mx + b

Where m is the slope of the line and b is the y intercept.

Given the function:

y = -(x/3) + 2

At x = -3:

y = -((-3)/3) + 2 = 3

At x = 0:

y = -(0/3) + 2 = 2

Step-by-step explanation:

Given that,

[tex]\dfrac{1}{f}=\dfrac{1}{u}+\dfrac{1}{v}\\\\\dfrac{1}{u}=\dfrac{1}{f}-\dfrac{1}{v}\\\\\dfrac{1}{u}=\dfrac{1}{(-7.5)}-\dfrac{1}{30}\\\\u=-6\ cm[/tex]
