HELP MEEEEE (find the values of z and y)

Answer:

13.2

Step-by-step explanation:

Let 4x represent the chocolate chip cookies

Let 3x represent the spice cookies

Let 3x represent ginger cookies

4x + 3x + 3x = 33

10x = 33

x = 33/10

x = 3.3

Since 4x represents chocolate chip cookies

4 × 3.3

= 13.2

Hence there are 13.2 chocolate chip cookies

Answer:

El taxista obtiene un beneficio de 1.750 € por la venta del taxi el 30 de junio de 2.015.

Step-by-step explanation:

El coche experimenta depreciación a medida que cubre su vida útil hasta caer a su valor residual, es decir, el valor del bien al término de su vida útil. En primer lugar, derivamos una ecuación del precio actual del coche en función del tiempo transcurrido bajo el supuesto de que existe una relación lineal:

[tex]C(t) = C_{o} + \frac{C_{f}-C_{o}}{\Delta t} \cdot t[/tex], para [tex]0\leq t\leq \Delta t[/tex] (1)

Donde:

[tex]C(t)[/tex] - Precio actual del coche, medido en euros.

[tex]C_{o}[/tex] - Precio inicial del coche, medido en euros.

[tex]C_{f}[/tex] - Precio residual del coche, medido en euros.

[tex]\Delta t[/tex] - Vida útil del coche, medida en años.

[tex]t[/tex] - Tiempo actual del coche, medida en años.

El precio actual del coche se obtiene a partir de los siguientes parámetros:

([tex]C_{o} = 30.000\,EUR[/tex], [tex]C_{f} = 3.000\,EUR[/tex], [tex]\Delta t = 10\,yr[/tex], [tex]t = 2.5\,yr[/tex])

[tex]C(t) = 30.000\,EUR +\left(\frac{3.000\,EUR-30.000\,EUR}{10\,yr} \right)\cdot (2.5\,yr)[/tex]

[tex]C(t) = 23.250\,EUR[/tex]

El beneficio derivado por la venta del coche ([tex]\Delta C[/tex]), medido en euros, se obtiene mediante la siguiente sustracción:

[tex]\Delta C = V-C[/tex] (2)

Donde:

[tex]V[/tex] - Precio de venta del coche, medido en euros.

[tex]C[/tex] - Precio actual del coche, medido en euros.

Si tenemos que [tex]V = 25.000\,EUR[/tex] y   [tex]C = 23.250\,EUR[/tex], el beneficio obtenido por la venta es:

[tex]\Delta C = 25.000\,EUR-23.250\,EUR[/tex]

[tex]\Delta C = 1.750\,EUR[/tex]

El taxista obtiene un beneficio de 1.750 € por la venta del taxi el 30 de junio de 2.015.

Answer:

£ 537.63

Step-by-step explanation:

original price = 100%

selling price = 100% - 7% = 93% = £500

just do the proportion or ratio

[tex] \frac{100\%}{93\%} = \frac{original \: price}{500} [/tex]

OP = 500 x 100% / 93%

OP = £ 537.634

rounded to the nearest penny and become £ 537.63

Answer:

Maximum value of z = 21

Minimum value of z = -9

Step-by-step explanation:

We have to maximize/minimize the given equation for the given constraints as,

x ≥ -1

y ≤ -2x + 3

y ≥ -1

By using the graphing tool,

Corner points for the feasible region are,

A(-1, 5), B(-1, -1) and C(2, -1)

For A(-1, 5),

z = 4x + 5y = 4(-1) + 5(5)

                  = -4 + 25

                  = 21

For B(-1, -1),

z = 4(-1) + 5(-1)

  = -4 - 5

  = -9

For C(2, -1),

z = 4(2) + 5(-1)

  = 8 - 5

  = 3

Maximum value of z = 21

Minimum value of z = -9

Answer:

40) 105 miles (mi)

42) 3.2 centimeters (cm)

Step-by-step explanation:

First determine which part of the ratio corresponds to what. Once you have figured that out, divide by the part of the ratio that corresponds to your given part and then multiply that by the other part of the ratio to derive the quantity.

If a:b

Then a × a/b = b, and b × a/b = a.

You can think of : as "to".

For example, you are given a map with a scale ratio of 1 in : 20 mi, this means that for every inch of the map, there is an actual distance of 20 miles.

So in this situation, the left part of the ratio is the length of the map in inches, and the right part of the ratio is the real distance in miles. For x inches of the map, there is 20 x miles of actual distance. Therefore 3.5 inches has an actual distance of 3.5 × 20 miles or 105 miles of actual distance.

For problem 2, you are given a ratio of 1 m : 2 cm, this means that for every 1 meter of the drawing, there is 2 cm of the plant. Therefore if you have 1.6 meter of the map, then you have 1.6 × 2 cm of the plant or 3.2 cm. For both situations the left part of the ratio is 1 which means that you just multiply by the right part of the ratio by which you are given.

Answer:

50%

Step-by-step explanation:

Calculation for What percent of the people surveyed were satisfied with the​ car

Using this formula

Percentage of people satisfied=Owners of car/Numbers of people to buy the same car again

Let plug in the formula

Percentage of people satisfied=1,700/3,400 people*100

Percentage of people satisfied=0.5*100

Percentage of people satisfied=50%

Therefore the percentage of the people surveyed who were satisfied with the​ car is 50%

Answer:

Are sure the question is correct please

Please check your out again carefully.

Answer:

The correct answer is B.)

Step-by-step explanation:

How many questions was the test? Was it 34 or 44?

The expression (x² + 3) / (x-3)(x-1) is the simplified form of the given expression. which is the correct answer would be an option (B).

Expressions are defined as mathematical statements that have a minimum of two terms containing variables or numbers.

The expression is given below as:

(x-3)/(x-1) + 6/(x-3)

To simplify the expression, we can first combine the terms that have a common denominator:

(x-3)²+ 6(x-1) / (x-3)(x-1)

We can simplify the expression further by using the fact that

(x² + 9 - 6x + 6x - 6) / (x-3)(x-1)

Combine the likewise terms and apply the arithmetic operation,

(x² + 3) / (x-3)(x-1)

Thus, the simplified expression is:

(x² + 3) / (x-3)(x-1)

Answer:

1 / ( 243s^40 )

Step-by-step explanation:

For this problem, we need to know that a negative exponent simply can be rewritten in the opposing part of the fraction, for this case, the denominator.  So we can simplify as shown:

(3s^8)^-5

= 1 / (3s^8)^5

= 1 / 3^5 * s^8^5

= 1 / 243 * s^40

= 1 / ( 243s^40 )

Cheers.

The expression [tex]\left (3s^8 \right )^{-5}[/tex] is simplified as equal to [tex]\boldsymbol{3s^{-40}}[/tex]

The amount of times an integer is multiplied on its own is referred to as an exponent.

Given expression is [tex]\boldsymbol{\left (3s^8 \right )^{-5}}[/tex]

Use the formula: [tex]\boldsymbol{\left ( a^m \right )^n=a^{mn}}[/tex] to simplify the expression.

[tex]\left (3s^8 \right )^{-5}=3s^{8\times (-5)}[/tex]

           [tex]=\boldsymbol{3s^{-40}}[/tex]

So, the expression is simplified as equal to [tex]\boldsymbol{3s^{-40}}[/tex]
