The measure of the exterior angle of the triangle is
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,
The interior angles are 24 and 2x + 18. The exterior angle is 3x + 6.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

A taxi driver fills the gas tank and calculates that the car traveled 356.35 miles using 9.5 gallons of gas how many miles per gallon did the car get?Do not enter label only the number part of the anwser
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.

Marg earns $13.10 an hour and works 40 regular hours and 8 hours of overtime in one week. If she is paid time and a half for overtime, what is her gross pay for the week?
Answer:
Her gross pay for the week is $681.2.
Step-by-step explanation:
First, you can determine the amount she would earn for working 40 regular hours by multiplying the number of hours for the amount she receives per hour:
$13.10*40=$524
Now, to calculate the amount Marg earns for 8 hours of overtime, you need to determine the amount she earns per hour of overtime given that she is paid time and a half which means that you need to multiply the amount she earns by regular hour for 1.5. Then, you have to multiply this for the number of hours:
($13.10*1.5)*8=$157.2
Finally, you need to add the amount she earns by working 40 regular hours plus the amount she earns by working 8 hours of overtime in one week:
$524+$157.2=$681.2
According to this, the answer is that her gross pay for the week is $681.2.
Un marino está parado en la proa de un velero y observa el faro en la orilla de la costa.Si el marino tiene una estatura de 1.80m y proyecta una sombra de 2m de largo sobre el velero,¿a que distancia se encuentra este hombre de la costa si se sabe que la altura del faro respecto al nivel Del Mar es de 36m?
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.

Imagina que vas a un partido de béisbol con tus amigos, y tienen hambre. El costo de dos botellas de agua y 3 bolsas de palomitas es de $65. El costo de 4 botellas de agua y 1 bolsa de palomitas es de $55. Para saber cuánto pagaría cada uno, determina el costo de una botella de agua y de una bolsa de palomitas.
(Considera que x=agua y y= palomitas)
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:
x= el costo de una botella de agua.y= el costo de una bolsa de palomitas.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.

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

Bottle contains 64 fluid ounces of syrup. Each day, you use 3 1/5 fluid ounces of syrup from the bottle. Is there enough syrup in the bottle for 25 days?
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.
