Answer:

327.6 €

Step-by-step explanation:

you can solve with an equation

1£ : 1.17€ = 280£ : x

1 : 1.17 = 280 : x

x = 1.17 * 280 : 1

x = 327.6

-------------------

check

1 : 1.17 = 280 : 327.6

0.85 = 0.85

the answer is good

------------------------------------

or you can simpy solve with a multiplication

280 * 1.17 = 327.6

Step-by-step explanation:

Answer:

an equation between two variables that gives a straight line when plotted on a graph. In mathematics, a linear equation is an equation that may be put in the form {\displaystyle a_{1}x_{1}+\cdots +a_{n}x_{n}+b=0, } where x_{1}, \ldots, x_{n} are the variables, and {\displaystyle b, a_{1}, \ldots, a_{n}} are the coefficients, which are often real numbers.

Answer:

The tax on the car equals $480, based on a 6% rate.

Step-by-step explanation:

Giving the following information:

Tax rate (t)= 6% = 0.06

Purchase price= $8,000

To calculate the tax (T), we need to use the following formula:

Tax= tax rate*purchase price

Tax= 0.06*8,000

Tax= $480

The tax on the car equals $480, based on a 6% rate.

Answer:

5(3x+1) or 15x+5

Step-by-step explanation:

A regular pentagon has 5 sides of equal length. The perimeter is the sum of the lengths of those sides. We can use multiplication to find the sum of 5 of the same value:

 P = 5(3x +1)

Perhaps you want it expanded. Using the distributive property, we multiply each term in parentheses by 5:

 P = 15x + 5

Answer:

Area= π(R^2-r^2)

Step-by-step explanation:

Although I can't find the attached file

Let the radius of the large circle be R

And the radius of the small circle be r

Area of large circle is

Area= πR^2

Area of small circle is

Area= πr^2

The difference is

Area= πR^2- πr^2

Area= π(R^2-r^2)

Answer:

Those points are in Quadrant 3

Answer:

The area of the roof is 3.80 m².

Step-by-step explanation:

The lateral surface area of an octagonal pyramid is given by:

[tex]A = 2s(\sqrt{4h^{2} + 5.828s^{2}})[/tex]   (1)

Where:

s: is the length of the base edge = 0.5 m

h: is the height                                                                                                      

We can find the height from the slant height (S = 1.9 m):

[tex] S = \sqrt{h^{2} + 1.457s^{2}} [/tex]   (2)

By solving equation (2) for "h" we have:

[tex] h = \sqrt{S^{2} - 1.457s^{2}} = \sqrt{(1.9)^{2} - 1.457(0.5)^{2}} = 1.80 m [/tex]

Now, we can calculate the area of the roof (equation 1):

[tex]A = 2s(\sqrt{4h^{2} + 5.828s^{2}}) = 2*0.5(\sqrt{4(1.80)^{2} + 5.828(0.5)^{2}}) = 3.80 m^{2}[/tex]

Therefore, the area of the roof is 3.80 m².

I hope it helps you!        

Answer:

Exponential

Step-by-step explanation:

If it were quadratic, y-axis would fall and rise in points, so its not quadratic.

If it were linear, it would have a pattern with a rise/over formula, and it doesn't go in a pattern, so the only answer left is: Exponential.

Answer:

Exponential

Calculate the distance d using the distance formula

d = [tex]\sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2 }[/tex]

with (x₁, y₁ ) = (3, - 6) and (x₂, y₂ ) = (- 1, - 8)

d = [tex]\sqrt{(-1-3)^2+(-8+6)^2}[/tex]

   = [tex]\sqrt{(-4)^2+(-2)^2}[/tex]

Answer:

p=40

Step-by-step explanation:

Hi there!

p-4=36

Our goal here is to isolate p on one side of the equal sign, and we can use the help of opposite operations to do this.

Right now, the only other value with p on the left side of the equal sign is -4. To isolate p, add +4 on both sides so -4 and +4 cancels out:

p-4+4=36+4

p=40

Therefore, p=40.

I hope this helps!

Answer:

Step-by-step explanation:

First thing you do is to isolate the term of p from one side of an equation.

Add by 4 from both sides.

[tex]\sf{p-4+4=36+4}[/tex]

Solve.

[tex]\sf{36+4=40}[/tex]

[tex]\large\boxed{p=40}[/tex]

Therefore, the final answer is p=40.

Answer:

The width of the frame is 2 inches

Step-by-step explanation:

The given dimensions of the picture = 7 inches by 7 inches

The area of the picture, A₁ = 7 in. × 7 in. = 49 in.²

The area of the given picture and the frame, A₂ = 81 square inches

Let 'w' represent the width of the frame and whereby the picture is a square, we have;

The area of the picture with the frame, A₂ = 81 in.² = (7 + w) × (7 + w)

A₂ = 81 = (7 + w) × (7 + w) = 49 + 14·w + w²

49 + 14·w + w² - 81 = 0

w² + 14·w - 32 = 0

(x + 16)·(x - 2) = 0

∴ x = -16 or x = 2

Given that 'x' is a natural number, we have;

The width of the frame, x = 2 inches.

Answer:

133 windows in 7 hours

Step-by-step explanation:

38 divided by 2 and you get 19

19 x 7 = 133

Answer:

133 windows

Step-by-step explanation:

First, you would want to find how many windows he can clean in 1 hour.

You know that 38 windows = 2 hours.

To do this, divide both sides by 2 (to get 1 hour). You will get 19 windows = 1 hour.

Now to find 7 hours, multiply both sides of 19 windows = 1 hour by 7 (to get 7 hours). You will get 133 windows cleaned in 7 hours.

Answer:

153.94

Step-by-step explanation:

c=2r*r

The radius is half of the diameter.

To find the radius you will divide 49 inches by 2.

You should get a total of 24.5

Now that you have your radius you are going to use the circumference formula to solve.

C= 2r*r

C=2(24.5)*(24.5)

type that into the calculator (without the parenthesis) and boom your done!

You answer should be 153.938

then you round to get a total of 153.94

I hope i was able to help!

Answer: c = 3771.481981 (decimal place) or 1200.5[tex]\pi[/tex] (exact form)

Step-by-step explanation:

c = 2[tex]\pi[/tex]r

c = 2 x [tex]\pi[/tex] x [tex]24.5^{2}[/tex]

radius = diameter divided by 2

          = 49 divided by 2
