La profundidad de una alberca aumenta paulatinamente desde 0.80 metros hasta 3 metros en una longitud de 10 metros cual es el angulo de inclinacion de la alberca
Answer:
El ángulo de inclinación de la alberca es aproximadamente 12.407º.
Step-by-step explanation:
Puesto que conocemos la distancia horizontal ([tex]l[/tex]) y la variación en la profundidad ([tex]h[/tex]) de la alberca, en metros, podemos emplear la siguiente razón trigonométrica para calcular el ángulo de inclinación de la alberca ([tex]\alpha[/tex]), en grados sexagesimales:
[tex]\alpha = \tan^{-1}\left(\frac{h}{l} \right)[/tex] (1)
Si sabemos que [tex]l = 10\,m[/tex] y [tex]h = 2.20\,m[/tex], entonces el ángulo de inclinación de la alberca es:
[tex]\alpha \approx 12.407^{\circ}[/tex]
El ángulo de inclinación de la alberca es aproximadamente 12.407º.

Una fábrica produce tres tipos de balones de fútbol, con un costo mensual de
$24,250.00 por cada 1125 balones. Los costos de fabricación son $ 40.00, $ 30.00 y $
20.00. Estos balones se venden en $ 160.00, $ 120.00 y $ 100.00, respectivamente.
¿Cuántos balones de cada tipo se fabrican si la ganancia mensual es de $ 92,750.00?
Answer:
Se fabricaron:
1000 balones de los que cuestan $20
75 balones de los que cuestan $30
50 balones de los que cuestan $40
Step-by-step explanation:
Vamos a definir las variables:
x = número de balones de $100.00 vendidos.
y = número de balones de $120.00 vendidos
z = número de balones de $160,00 vendidos.
Sabemos que se producen 1125 balones, entonces:
x + y + z = 1125
y el costo de producción es $24,250, conociendo el costo de cada balón podemos escribir:
x*$20 + y*$30 + z*$40 = $24,250
Y también sabemos que la ganancia mensual es $92,750
Ganancia es la diferencia entre el dinero total recibido y los costos, entonces:
x*$100 + y*$120 + z*$160 - $24,250 = $92,750
x*$100 + y*$120 + z*$160 = $92,750 + $24,250
x*$100 + y*$120 + z*$160 = $117,000
Entonces tenemos un sistema de 3 ecuaciones:
x + y + z = 1125
x*$20 + y*$30 + z*$40 = $24,250
x*$100 + y*$120 + z*$160 = $117,000
Para resolver esto debemos comenzar por aislar alguna variable en alguna de las ecuaciones, yo comenzare aislando x en la primera ecuación:
x = 1125 - y - z
Ahora podemos reemplazar esto en las otras dos ecuaciones para obtener:
(1125 - y - z)*$20 + y*$30 + z*$40 = $24,250
(1125 - y - z)*$100 + y*$120 + z*$160 = $117,000
Si simplificamos esto obtenemos:
$22,500 + y*$10 + z*$20 = $24,250
$112,500 + y*$20 + z*$60 = $117,000
Ahora de vuelta, debemos aislar una variable en una de las ecuaciones, si aislamos y en la primera ecuación obtenemos:
y*$10 = $24,250 - $22,500 - z*$20
y = ($1,750 - z*$20)/$10
y = 175 - 2*z
Reemplazando esto en la otra ecuación obtenemos:
$112,500 + (175 - 2*z)*$20 + z*$60 = $117,000
Ahora podemos resolver esto para z.
(175 - 2*z)*$20 + z*$60 = $117,000 - $112,500
(175 - 2*z)*$20 + z*$60 = $4,500
$3,500 - z*$40 + z*$60 = $4,500
$3,500 + z*$20 = $4,500
z*$20 = $4,500 - $3,500 = $1,000
z = $1,000/$20 = 50
Entonces tenemos 50 balones de los que cuestan $40.
Usando la ecuación y = 175 - 2*z podemos encontrar el valor de y.
y = 175 - 2*50 = 75
Entonces tenemos 75 balones de los que cuestan $30.
Usando la ecuación x = 1125 - y - z podemos encontrar el valor de x.
x = 1125 - 75 - 50 = 1000
tenemos 1000 balones de $20.

Step-by-step explanation:
y = x-3
So, y + 3 = x
x = y + 3
if x = 7
y = 7 - 3 = 4
if y = 1
x = 1 + 3 = 4

The diameter of a circle is 38 miles. What is the circle’s area?
Use 3.14 for pi
Area of circle formula: πr^2
Since the radius is half of the diameter, divide 38 by two.
r = 19 miles
A = π(19)^2 = π(361)
Now, substitute in 3.14 for π
A = 3.14(361) = 1133.54

1.)Probability that exactly 3 fail
2.) Fewer Than 3 fail
Answer:
0.1026 ;
0.8623
Step-by-step explanation:
Using the binomial probability formula :
P(x =x) = nCx * p^x * (1 - p)^(n - x)
p = 0.11
1 - p = 1 - 0.11 = 0.89
n = 12
P(x = 3) = 12C3 * 0.11^3 * 0.89^0
P(x = 3) = 0.1026
Fewer Than 3
P(x < 3) = p(x = 0) + p(x = 1) + p(x = 2)
Using a binomial probability calculator :
P(x = 0) = 0.2470
P(x = 1) = 0.3663
P(x = 2) = 0.2490
(0.2470 + 0.3663 + 0.2490) = 0.8623

In a high school orchestra, the ratio of cellos to violins is 1 to 3. There are 21 violins. Write and solve a proportion that gives the number c of cellos in the orchestra.
Answer:Number of cellos =7
Step-by-step explanation:
The ratio of cellos to violins is 1 to 3=1:3
Total ratio = 1+3=4
To find the total number of cellos and violins in the orchestrs,
Ratio of violins/ Total ratio x Total number of cellos and violins = Number of violins
3/4 x X= 21
X=21 x 4 / 3
X =7x 4 28.
Number of cellos =Ratio of cellos / Total ratio x Total number of cellos and violins
=1/4 x28
=7 cellos
