What does AD equal? PICTURE INCLUDED* Triangle congruence and similarity.
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]
What is the equation of the line that passes through the point (-4,-3)and has a slope of 3/4
Answer:
y=3/4x
Step-by-step explanation:
y-y1=m(x-x1)
y-(-3)=3/4(x-(-4))
y+3=3/4(x+4)
y=3/4x+12/4-3
y=3/4x+3-3
y=3/4x
finding angle measures with trig. Find the missing angle measures. Round to the nearest whole number
Answer:
let angle be x
Step-by-step explanation:
relationship between perpendicular and hypotenuse is given by sin angle
sin x =p/h
sin x=13/26
x=sin-¹(13/26)=30°
2.relationship between perpendicular and base is given by tan angle
tan x =p/b
tan x =7/16
x=tan -¹(7/16)=23.63°
3.relationship between between perpendicular and base is given by tan angle
tan x =p/b
tanx=31/50
x=tan-¹(31/50)=31.8°
4.relationship between base and hypotenuse is given by cos angle
cos x =b/h
cos x=5/7
x=cos-1(5/7)=44.4°
5.relationship between perpendicular and hypotenuse is given by sin angle
sin x =p/h
sin x=4/14
x=sin-¹(4/14)=16.6
6..relationship between base and hypotenuse is given by cos angle
cos x=6/7
x=cos-¹(6/7)=31.0027
7.relationship between perpendicular and base is given by tan angle
.tanx=29/37
x=tan-¹(29/37)=38.09
8.relationship between perpendicular and hypotenuse is given by sin angle
.sin x=43/60

What is the total length of all the ski trails that are 2 7/8 miles long?
Answer:
[tex]Total\ length = 8\frac{5}{8}\ miles[/tex]
Step-by-step explanation:
Given
See attachment for ski trails
Required
Total length of [tex]2\frac{7}{8}[/tex] ski trails
From the attached figure, there are 3 skis with length [tex]2\frac{7}{8}\ miles[/tex]
So:
The total length is:
[tex]Total\ length = 3 * 2\frac{7}{8}[/tex]
Express fraction as improper fraction
[tex]Total\ length = 3 * \frac{23}{8}[/tex]
[tex]Total\ length = \frac{3 *23}{8}[/tex]
[tex]Total\ length = \frac{69}{8}[/tex]
[tex]Total\ length = 8\frac{5}{8}\ miles[/tex]
(PLEASE) Triangle IJK is similar to triangle LMN. Find the measure of side MN. Round your answer to the nearest tenth if necessary. Figures are not drawn to scale.
Answer:
MN = 126.31Step-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.
What are Similar Triangles?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

5. 2.5 x + 20 = 25
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

What is the equation of the line that passes through the point (-6,4)
and has a slope of -5/6
Answer: y = -5/6 x - 1
Step-by-step explanation:
The slope is -5/6, which is why x = -5/6. The - 1 is so the line on the graph will pass through (0,-1) and (-6,4).
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.

Use sigma notation to represent the sum of a geometric series with a first term of 3 and a common ratio of . A. B. C. D.
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]
