Answer:

35 degrees

Step-by-step explanation:

since the total has to be 180

100 + 45 = 145

180 - 145 = 35 degrees

Answer:

35 degrees

Step-by-step explanation:

A triangle is 180 degrees and 45 and 100 is already there.

So... 180-45-100=35

That is how you get 35 degrees

Answer:

50

Step-by-step explanation:

as triangle is =180

then , 30 +100 +x =180

130 +x = 180

x= 180-130

=50

Answer:

50 degrees

Step-by-step explanation:

A triangle is 180 degrees and there is already a 30 and 100.

180-30-100=50.

Answer:

AD = 7

Step-by-step explanation:

Given that the two triangles are similar by the SSS (side side side) postulate, the triangles share the same ratios when it comes to their sides.

We know the values for lines DB, EB and CB, therefore we can solve for AB, and subtract DB to find AD

We can solve the problem by solving for x:

[tex]\frac{x}{32} =\frac{21}{24}[/tex]

Cross multiply.

[tex]24x = 672[/tex]

Simplify.

[tex]x=28[/tex]

Subtract the value of DB to find AD.

[tex]28-21=7[/tex]

[tex]AD=7[/tex]

Answer:

x= 2

Step-by-step explanation:

Subtract 20 from both sides

2.5x + 20 − 20 = 25 − 20

2.5x= 5

Divide both sides by 2.5

2.5x/2.5= 5/2.5

x= 2

So, y + 3 = x

x = y + 3

if x = 7

y = 7 - 3 = 4

Complete question :

Of all the registered automobiles in a city, 11% fail the emissions test. Twelve automobiles are selected at random to undergo an emissions test. Round the answers to four decimal places.

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

Answer:

[tex]\Sigma_{k=1}^{n}[3(\frac{10}{9} )^{k-1}][/tex]

Step-by-step explanation:

A geometric sequence is a list of numbers having a common ratio. Each term after the first is gotten by multiplying the previous one by the common ratio.

The first term is denoted by a and the common ratio is denoted by r.

A geometric sequence has the form:

a, ar, ar², ar³, . . .

The nth term of a geometric sequence is [tex]ar^{n-1}[/tex]

Therefore the sum of the first n terms is:

[tex]\Sigma_{k=1}^{n}(ar^{k-1})[/tex]

Given a geometric series with a first term of 3 and a common ratio of 10/9, the sum of the first n terms is:

[tex]\Sigma_{k=1}^{n}[3(\frac{10}{9} )^{k-1}][/tex]

Answer:

not a polygon

Step-by-step explanation:

The given figure is not a polygon.

A polygon is a closed plane figure formed by three or more line segments that meet at points called vertices.

Given is figure,

We know that, a polygon is made up of straight lines connected with each other in a close circuit.

Here, in the figure, there is no polygon, but two polygons joined by a vertex.

Hence, we can say that the given figure is not a polygon.

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.

Answer:

Step-by-step explanation:

ΔIJK = ΔLMN --- (given)

So,-----------------------

KI / KJ = NL / MN

19 / 40 = 60 / MN

MN = 60 × 40 / 19

MN = 126.31

The required measure of side MN will be 126.3 units.

Similar Triangles are defined as two triangles with the same shape, equal pair of corresponding angles, and the same ratio of the corresponding sides. The triangles that like one another but may not be exactly the same size are said to be similar triangles.

Given that triangle ΔIJK ~ ΔLMN in the question.

We know that Similar triangles with the same shape, equal pair of corresponding angles, and the same ratio of the corresponding sides.

As per the similarity rule of triangles, we can write the ratio as:

⇒ KI / KJ = NL / MN

⇒ 19 / 40 = 60 / MN

⇒ MN = 60 × 40 / 19

⇒ MN = 126.3157

Rounded to the nearest tenth to get

⇒ MN = 126.3
