Answer:

Area of sector = 11.8 m² (Approx.)

Step-by-step explanation:

Given:

Radius of a circle = 3 m

Given angle = 150°

Find:

Area of sector

Computation:

Area of sector = [θ/360][π][r]²

Area of sector = [150/360][22/7][3]²

Area of sector = [150/360][22/7][9]

Area of sector = [150/360][3.1428][9]

Area of sector = [0.4167][3.1428][9]

Area of sector = [1.345][9]

Area of sector = 11.789

Area of sector = 11.8 m² (Approx.)

Answer:

The right answer is approximately 210.031 cubic inches. (Answer: E)

Step-by-step explanation:

First, we need to convert the diameter ([tex]D[/tex]), in inches, of the round balloon to an entirely decimal mode:

[tex]D = 7\,in + \frac{3}{8}\,in[/tex]

[tex]D = \frac{56 + 3}{8}\,in[/tex]

[tex]D = \frac{59}{8}\,in[/tex]

[tex]D \approx 7.375\,in[/tex]

The volume of the balloon is modelled after the volume function of a sphere ([tex]V[/tex]), in cubic inches:

[tex]V = \frac{\pi}{6}\cdot D^{3}[/tex] (1)

If we know that [tex]D \approx 7.375\,in[/tex], then the volume of the round balloon is:

[tex]V = \frac{\pi}{6}\cdot D^{3}[/tex]

[tex]V = \frac{\pi}{6} \cdot (7.375\,in)^{3}[/tex]

[tex]V \approx 210.031\,in^{3}[/tex]

Hence, the right answer is approximately 210.031 cubic inches.

Answer:

a. 47.5%

Step-by-step explanation:

1. Find the z-score for 405: 405-455/25 = -2

2. Find the z-score for 455: 455-455/25 = 0

3. Using technology or a chart, find the percentage that corresponds with the z-scores: -2 = 0.0228 or 2.28%, AND 0 = 0.5000 or 50%

4. Find the difference between the percentages by subtracting them: 50% - 2.28% = 47.72%

5. Most of the time, the answers aren't exact, so since 47.72% is closest to 47.5%, I would say that's the answer.

Answer:

Perimeter = 133.681 cm

or 52.63 inches.

Step-by-step explanation:

"So, the perimeter of a semicircle is 1/2 (πd) + d or πr + 2r, where r is the radius."

let's use,  πr + 2r

Diameter: 52

Radius: 26 (RAdius is half of the diameter)

πr + 2r (plug in)

pi x 26 + 2(26)

pi x 26 + 52

= 133.681 cm

or

= 52.63

Resolviendo un sistema de ecuaciones veremos que polo hizo 170 polos.

Sabemos que por cada 12 polos que confecciona Ana, Beto hace 7.

Por cada 28 polos que confecciona Beto, Carla confecciona 15.

Y sabemos que Ana hizo 198 polos mas que Carla.

Definamos las variables:

C = polos que hizo Carla.

A = polos que hizo Ana

B = polos que hizo Beto.

Podemos escribir las ecuaciones:

A = C + 198

B = (7/19)*A

B = 28/(28 + 15)*C

Tenemos un sistema de ecuaciones, las segundas dos son las que obtenemos con los ratios que nos proporcionan.

Reemplazando la primer ecuacion en la segunda obtenemos el sistema:

B = (7/19)*(C + 198)

B = 28/(43)*C

De la segunda ecuacion podemos obtener:

C = B*(43/28)

Remplazando eso en la otra ecuacion obtenemos:

B = (7/19)*(B*(43/28)+ 198)

Ahora podemos encontrar el valor de B.

B = 0.57*B + 72.95

B - 0.57*B =  72.95

B*0.43 = 72.95

B = 72.95/0.43 = 169.6

Redondenado, B = 170, ese es el número de polos que Beto confecciono.

Answer:

[tex]y = 4x+17[/tex]  

Step-by-step explanation:

1) First, write the equation of the line in point-slope form. From there, we can convert it to slope-intercept form. Use the point-slope formula [tex]y-y_1 = m (x-x_1)[/tex]  and substitute values for [tex]m[/tex], [tex]x_1[/tex], and [tex]y_1[/tex].

[tex]m[/tex] represents the x and y values of one point the line intersects, so  substitute 4 in its place. [tex]x_1[/tex] and [tex]y_1[/tex] represent the x and y values of one point the line intersects, so substitute -3 for [tex]x_1[/tex] and 5 for [tex]y_1[/tex]. This gives the following equation in point-slope form:

[tex]y-5 = 4(x+3)[/tex]

2) Now, put it in [tex]y =mx + b[/tex] format, or slope-intercept form by isolating the y:

[tex]y-5 = 4(x+3)\\y-5 = 4x + 12\\y = 4x+17[/tex]

The equation of a line with a slope of 4 that passes through the point (-3,5) in slope intercept form is,y=4x+17.

A numerical assessment of a line's angle relative to the ground is known as the slope.

The inclination of any line, ray, or line segment is the fraction of the perpendicular to the horizontal distance between any two positions on it.

The line's equation in point-slope form is;

 y = mx+c

We may then transform it to a slope-intercept form. Substitute values in the point-slope formula as;

y-y₁=m(x-x₁)

y-5=4(x-(-3)

y-5=4(x+3)

y--5=4x+12

y-4x+17

Hence,the equation of a line with a slope of 4 that passes through the point (-3,5) in slope intercept form is,y=4x+17.

Answer:

  A) $157,555

Step-by-step explanation:

The sum of assets is ...

  house + 2 cars = $280,000 +5,200 +15,600 = $300,800

The sum of liabilities is ...

  mortgage +car loan +credit card +wedding

  = $113,545 +9,200 +2,300 +18,200 = $143,245

The family's net worth is the difference between assets and liabilities:

  $300,800 -143,245 = $157,555

Answer:

The standard deviation of the probability distribution is 1.02.

Step-by-step explanation:

Standard deviation of the distribution:

Square root of the sum of the difference squared between each value and the mean multiplied by its probability.

Mean:

Each value multiplied by its probability. So

[tex]E(X) = 0*0.1 +1*0.5 + 2*0.1 + 3*0.3 = 1.6[/tex]

Standard deviation:

[tex]\sqrt{V(X)} = \sqrt{0.1*(0-1.6)^2 + 0.5*(1-1.6)^2 + 0.1*(2-1.6)^2 + 0.3*(3-1.6)^2} = 1.02[/tex]

The standard deviation of the probability distribution is 1.02.

Answer: It took the train 11 s to completely pass the other.

11 seconds it takes for them to completely pass one another if one train is travelling 120 m with a velocity of 52 km/h.

Distance is a numerical representation of the distance between two items or locations. Distance refers to a physical length or an approximation based on other physics or common usage considerations.

We have:

One train is travelling 120 m with a velocity of 52 km/h.

A second train is travelling in the opposite direction with a velocity of 20 km/h.

Here, the length of the second train is not given:

We are assuming the length is 100 m

Relative velocity = 52+20 = 72 km/h = 20 meter/seconds

Total distance: = 120 + 100 = 220 m

The time = 220/20 = 11 seconds

Thus, 11 seconds it takes for them to completely pass one another if one train is travelling 120 m with a velocity of 52 km/h.
