Answer:

120 euros

Step-by-step explanation:

X= 100% del precio (antes de la rebaja)

Pagaste el 85% pues habia descuento del 15%

85%--------------102

100%---------------x

CROSS MULTIPLICATION

85X  =  10200

Divide cada parte por 85

x= 120

Teniendo en cuenta la definición de descuento, el precio antes de la rebaja era 120 €.

En una operación de descuento, el valor que se paga después de haberle practicado el descuento se denomina “valor actual”.  

Recordando que el porcentaje representa una parte del total, el valor actual se puede calcular multiplicando el porcentaje a descontar por el precio original,  al cual luego se divide por cien. Finalmente, se resta al precio original este valor de descuento calculado. De esta manera se averigua el precio de venta.

Entonces, sea el precio original del producto p. Por lo que el descuento del precio original será:

15% de p= (15×p) ÷10

Sabiendo que se ha pagado 102 € por el pantalón, entonces:

p - (15×p) ÷10 = 102

Resolviendo

p - 0,15×p= 102

0,85×p= 102

p= 102÷0.85

p= 120

Finalmente, el precio antes de la rebaja era 120 €.

Answer:

B

Step-by-step explanation:

The formula would be (y2-y1)/(x2-x1)

So, plugging it in, the equation would be (4+2)/(2-1)

Solving that, you get you a slope of 6.

Answer:

cosA = [tex]\frac{8}{17}[/tex]

Step-by-step explanation:

Using the identity

cosA = [tex]\frac{1}{secA}[/tex] = [tex]\frac{1}{\frac{17}{8} }[/tex] = [tex]\frac{8}{17}[/tex]

Answer:

8/17

Step-by-step explanation:

sec A = Hypotenuse/ Adjacent = 17/8

cos A = Adjacent / Hypotenuse = 8/17

Step-by-step explanation:

Answer:

Length of diagonal = 10 feet

Step-by-step explanation:

Length of a rectangular screen = 6 feet

Width of the rectangular screen = 8 feet

Since, all interior angles of a rectangle are 90°,

Triangle formed with two adjacent sides and the diagonal will be a right triangle.

By applying Pythagoras theorem,

Hypotenuse² = (leg 1)² + (leg 2)²

(Diagonal)² = (leg 1)² + (leg 2)²

Diagonal = [tex]\sqrt{6^2+8^2}[/tex]

               = [tex]\sqrt{100}[/tex]

               = 10 feet

(I think that says 51...)

Basically all you do is multiply 51 by 4

Answer:

The answer is Exponential

Exponential regression finds the equation of the exponential function that best fits the data points in the scatterplot.

The correct option is A.

As per the given diagram,

the scatter plot shows an exponential function.

To determine the best-fitting regression model for a scatterplot that follows an exponential function, we need to use exponential regression. Exponential regression finds the equation of the exponential function that best fits the data points in the scatterplot.

Therefore, an exponential regression model is appropriate.

Answer: the answer is D = 210cm

Given:

[tex]x = 1, y = 7,z = 15[/tex]

A number is added to x, y, and z yields consecutive terms of a geometric sequence.

To find:

The number which is added to  x, y, and z, then find the first three terms in the geometric sequence.

Solution:

Let the unknown number be k.

After adding k to x, y, and z, we get

[tex]x = 1+k, y = 7+k,z = 15+k[/tex]

These are the consecutive terms of a geometric sequence. So,

[tex](7+k)^2=(1+k)(15+k)[/tex]

[tex]49+14k+k^2=15+k+15k+k^2[/tex]

[tex]49+14k=15+16k[/tex]

Isolate the variable terms.

[tex]49-15=16k-14k[/tex]

[tex]34=2k[/tex]

[tex]\dfrac{34}{2}=k[/tex]

[tex]17=k[/tex]

The unknown number is 17.

Now,

[tex]x=1+k[/tex]

[tex]x=1+17[/tex]

[tex]x=18[/tex]

Similarly,

[tex]y=7+k[/tex]

[tex]y=7+17[/tex]

[tex]y=24[/tex]

And

[tex]z=15+k[/tex]

[tex]z=15+17[/tex]

[tex]z=32[/tex]

Therefore, the three terms in the geometric sequence are 18, 24, 32.

Answer:

The answer is C

Explain:

Solve for x in the first equation.

Add 4y to both sides of the equation

3x=12+4y

12y-9x=36

Divide each term by 3 and simplify

X=4+4y/3

12y-9x=36

Replace all occurrences of x with 4+4y/3 in each equation.

-36=36

X=4+4y/3

Since -36=36 is not true, there is no solution
