In ΔDEF, e = 8.7 inches, ∠F=8° and ∠D=34°. Find the length of f, to the nearest 10th of an inch.

Answer:

so you need to find x

Step-by-step explanation:

the little fraction beside the equation in parenthesis is what you are multiplying by, and 25 is what is equals , so x-7 times 2/3 or 0.67 = 25  we then divide 25 by 0.67 then plus 7 and the answer is 44.31

Answer: 35

Step-by-step explanation: 70% of 50 is 35

Given:

Total syrup = 64 fluid ounces

Syrup used each day = [tex]3\dfrac{1}{5}[/tex] fluid ounces

To find:

Whether there is enough syrup in the bottle for 25 days or not.

Solution:

According to the question,

Requirement of syrup for 1 day [tex]=3\dfrac{1}{5}[/tex] fluid ounces

                                                   [tex]=\dfrac{3\times 5+1}{5}[/tex] fluid ounces

                                                   [tex]=\dfrac{16}{5}[/tex] fluid ounces

Requirement of syrup for 25 day [tex]=25\times \dfrac{16}{5}[/tex] fluid ounces

                                                       [tex]=\dfrac{400}{5}[/tex] fluid ounces

                                                       [tex]=80[/tex] fluid ounces

Syrup required for 25 days is 80 fluid ounces which is greater than 64 fluid ounces.

Therefore,  64 fluid ounces of syrup is not enough for 25 days.

Answer:

32

Step-by-step explanation:

10  divided  by  5/2  or  2  and  1/2  is  4   4  x  8  =  32.

The exterior angle of a triangle is congruent to the sum of the opposite interior angles

The measure of the exterior angle of the triangle  is 114 degrees

From the figure,

So, the interior and exterior angles have the following relationship

[tex]\mathbf{3x + 6 = 2x + 18 + 24}[/tex]

Collect like terms

[tex]\mathbf{3x - 2x = -6 + 18 + 24}[/tex]

[tex]\mathbf{x = 36}[/tex]

The exterior angle is given as:

[tex]\mathbf{\theta = 3x + 6}[/tex]

Substitute 36 for x

[tex]\mathbf{\theta = 3 \times 36 + 6}[/tex]

[tex]\mathbf{\theta = 114}[/tex]

Hence, the exterior angle is 114 degrees

Answer:

El costo de una botella de agua es de $10

El costo de una bolsa de palomitas de maíz es de $15.

Step-by-step explanation:

Los parámetros dados son;

El costo de dos botellas de agua y 3 bolsas de palomitas de maíz = $65

El costo de 4 botellas de agua y 1 bolsa de palomitas de maíz = $55

Donde x = El costo de una botella de agua ey = El costo de una bolsa de palomitas de maíz, tenemos;

2 × x + 3 × y = 65 ... (1)

4 × x + y = 55 ... (2)

Haciendo y el tema de ambas ecuaciones, tenemos;

Para la ecuación (1), tenemos;

2 · x + 3 · y = 65

3 · y = 65 - 2 · x

y = 65/3 - 2/3 · x

Para la ecuación (2), tenemos;

4 · x + y = 55

y = 55 - 4 · x

Igualando ambos valores de y para encontrar la solución común, tenemos;

65/3 - 2/3 · x = 55 - 4 · x

4 · x - 2/3 · x = 55 - 65/3

10 · x / 3 = 100/3

∴ 10 · x = 100

x = 100/10 = 10

x = 10

El costo de una botella de agua = x = $10

y = 55 - 4 · x = 55 - 4 × 10 = 55 - 40 = 15

y = 15

El costo de una bolsa de palomitas de maíz = y = $15

Teniendo en cuenta la definición de sistema de ecuaciones lineales, el costo de una botella de agua es $10, mientras que el costo de una bolsa de palomitas es $15.

Un sistema de ecuaciones lineales es un conjunto de dos o más ecuaciones de primer grado, en el cual se relacionan dos o más incógnitas.

Resolver un sistema de ecuaciones consiste en encontrar el valor de cada incógnita para que se cumplan todas las ecuaciones del sistema. Es decir, se debe buscar los valores de las incógnitas, con los cuales al reemplazar, deben dar la solución planteada en ambas ecuaciones.

En este caso, se debe plantear un sistema de ecuaciones lineales teniendo en cuenta que:

Por un lado, se sabe que el costo de 2 botellas de agua y 3 bolsas de palomitas es de $65. Esto se expresa mediante: 2x + 3y= 65

Por otro lado, se sabe que el costo de 4 botellas de agua y 1 bolsa de palomitas es de $55, expresado mediante 4x + y= 55

Entonces, el sistema de ecuaciones a resolver es:

[tex]\left \{ {{2x+3y=65} \atop {4x+y=55}} \right.[/tex]

Existiendo diversos métodos para resolver un sistema de ecuaciones, se decide resolver mediante el método de sustitución , que consiste en despejar una de las dos variables en una de las ecuaciones del sistema y sustituir su valor en la otra ecuación.

En este caso, aislando la variable "y" de la segunda ecuación se obtiene:

y= 55 -4x

Reemplazando en la primer ecuación se llega a la expresión:

2x+3×(55 -4x)=65

2x +3×55 - 3×4x=65

2x + 165 - 12x=65

2x -12x= 65 -165

-10x=-100

x= (-100)÷ (-10)

x=10

Finalmente, para obtener el valor de y se reemplaza en la expresión anteriormente obtenida para y:

y= 55 -4x

y= 55 -4×10

y= 55 - 40

y=15

Finalmente, recordando que x representa el costo de una botella de agua e y representa el costo de una bolsa de palomitas, entonces el costo de una botella de agua es $10, mientras que el costo de una bolsa de palomitas es $15.

Answer:

4 mins

Step-by-step explanation:

Tank 1: 24

Tank 2: 8

Tanks 3: 12

So you add them all up to equal the "work". which is one. Looks like this:

*** x/24 + x/8 + x/12 = 1 ***

multiply all by 24

x+3x+2x=24

add like terms

6x=24

divided by 6

x=4

So x=4 minutes.

Answer:

El marino se encuentra a 40 metros de la costa.

Step-by-step explanation:

Podemos ver la conjunción de la proyección de la sombra del marino con su altura como un triángulo rectángulo con:

b: base = cateto inferior = 2 m

h: altura = cateto superior = 1.80 m

θ₁: ángulo entre la hipotenusa y h (cateto inferior o base).

De este primer triángulo tenemos:

[tex] tan(\theta_{1}) = \frac{h}{b} = \frac{1.80 m}{2 m} = 0.9 [/tex]   (1)

Ahora, dado que la proyección del marino se debe al faro, de la atura de éste junto con la distancia entre el marino y la costa tenemos:

x: distancia entre el marino y la costa = cateto inferior =?

H: altura del faro = cateto superior = 36 m

θ₂: ángulo entre la hipotenusa y "x" (base).

De este segundo triangulo tenemos:

[tex] tan(\theta_{2}) = \frac{H}{x} = \frac{36 m}{x} [/tex]  

[tex]x = \frac{36 m}{tan(\theta_{2})}[/tex]   (2)

Debido a que θ₁ = θ₂ (por ser los dos triangulos semejantes), entonces introduciendo la ecuación (1) en (2) tenemos:

[tex]x = \frac{36 m}{tan(\theta_{1})} = \frac{36 m}{0.9} = 40 m[/tex]

Por lo tanto, el marino se encuentra a 40 metros de la costa.

Answer:

The larger is 22, the smaller is 9.

Step-by-step explanation:

We need to make the two equations for this which would be:

x+y=31

x=2y+4

we can put the second equation into the first

(2y+4)+y=31

3y+4=31

subtract 4 from each side

3y=27

divide each side by 3

y=9

put this y into our second equation

x=2(9)+4

x=18+4

x=22

Answer:

37.5 miles per gallon

Step-by-step explanation:

In order to calculate the mileage per gallon of the car we simply need to divide the total number of miles that the car has travelled by the total amount of gas that is used during that time. Since we are given both of these values then we can simply go ahead and use these values to find the car's gas mileage...

356.35 / 9.5 = 37.5 miles per gallon

Finally, we can see that the taxi driver's car gets roughly 37.5 miles per gallon.

Step-by-step explanation:

To find the x- intercept, let y = 0 in the equation and solve for x, that is

x + 8(0) = - 9, that is
