Question

@kc_kennylau publicaré la foto del problema abajo!

Answer 1

okay :)

Answer 2

@kc_kennylau look at it :o

Answer 3

El significado de ete problema es solver la ecuacion:
10 sen ( pi*t/6 - 2*pi/3 ) +57 = 62

Answer 4

I'm bad with equations! No sé cómo resolverla. Would you like to explain me how to do it? :o

Answer 5

Convierte todo a grado si te gustaria

Answer 6

pi/6 = 30 grados
2*pi/3 = 120 grados

Answer 7

Yeah, and then?! :o

Answer 8

Saca 57 de los dos lados

Answer 9

10 sen ( pi*t/6 - 2*pi/3 ) +57 = 62
10 sen ( pi*t/6 - 2*pi/3 ) +57 - 57 = 62 - 57
10 sen ( pi*t/6 - 2*pi/3 ) = 5

Answer 10

Lo entendiste?

Answer 11

Absolutely NO! First, how did you get 62? :(

Answer 12

Porque la temperatura requerida es 62

Answer 13

ohhh ok, you got it from the problem? xD

Answer 14

Si :)

Answer 15

Yeah, I just saw it! Lol, I feel dumb :b

Answer 16

No no eres :)

Answer 17

Lol, ok! So.. Is that the answer?!? :O

Answer 18

Debemos aun lo resolver no?

Answer 19

I don{t know! What do you think? :o

Answer 20

10 sen ( pi*t/6 - 2*pi/3 ) +57 = 62
10 sen ( pi*t/6 - 2*pi/3 ) +57 - 57 = 62 - 57
10 sen ( pi*t/6 - 2*pi/3 ) = 5
sen (pi*t/6 - 2*pi/3) = 0.5

Answer 21

Lo comprendes?

Answer 22

Nope ._. did you subtract the (pi*t/6 - 2*pi/3) to get 0.5?

Answer 23

10 sen ( pi*t/6 - 2*pi/3 ) +57 = 62
10 sen ( pi*t/6 - 2*pi/3 ) +57 - 57 = 62 - 57
10 sen ( pi*t/6 - 2*pi/3 ) = 5
10 sen ( pi*t/6 - 2*pi/3 ) / 10 = 5 / 10
sen (pi*t/6 - 2*pi/3) = 0.5

Answer 24

Ahora lo comprendes?

Answer 25

ohh! you moved the 10 to the right so you divide 5/10? :o

Answer 26

Si :)

Answer 27

Cual es el siguiente paso?

Answer 28

I think that it is the part that says: ''Which two months is the average temperature 62°?'' Is it?

Answer 29

Solving equations are like attacking into a castle. You take down the furthest guards first. For example, in the equation 8(3t+4)=56, you remove the 8 first, then the 4, then finally the 3.

Answer 30

La ecuacion no esta resolvada :)

Answer 31

Encontrando el "t" estas

Answer 32

You don't say ''resolvada'' in Spanish, we say ''resolvida'' :D

Answer 33

I meant ''resuelta''

Answer 34

oh diculpe :p

Answer 35

lol c: so, what do we have to do next? :o

Answer 36

10 sen ( pi*t/6 - 2*pi/3 ) +57 = 62
10 sen ( pi*t/6 - 2*pi/3 ) +57 - 57 = 62 - 57
10 sen ( pi*t/6 - 2*pi/3 ) = 5
10 sen ( pi*t/6 - 2*pi/3 ) / 10 = 5 / 10
sen (pi*t/6 - 2*pi/3) = 0.5

Cual puede "pi*t/6 - 2*pi/3" estar?

Answer 37

Whaaaaaaat? I don't get it!!! :(

Answer 38

Si el seno de algo es 0.5, "algo" estaria cual?

Answer 39

Nope, I still don't get it :/

Answer 40

sen(algo)=0.5
algo=?

Answer 41

30°? AY NO! NO LO ENTIENDO! :O

Answer 42

Si!!! Si!!!

Answer 43

YAY!! :D

Answer 44

Y te introduzco una nueva formula: \(\mbox{sen}(x)=\mbox{sen}(\pi-x)\)

Answer 45

O in grados: \(\mbox{sen}(x)=\mbox{sen}(180^\circ-x)\)

Answer 46

Pero eta ecuacion no es en grados

Answer 47

Nope, it is in radians!

Answer 48

Entonces la formula es \(\mbox{sen}(x)=\mbox{sen}(\pi-x)\)

Answer 49

Que estaria "algo" aparte de 30 grados (o \(\dfrac\pi6\))?

Answer 50

I really don't know :o could you please tell me? :o

Answer 51

Porque \(\mbox{sen}30^\circ=\mbox{sen}150^\circ\), algo estaria tambien \(150^\circ\), o en radian \(\frac{5\pi}6\)

Answer 52

Hmm. So, what do we have to do next? :o

Answer 53

10 sen ( pi*t/6 - 2*pi/3 ) +57 = 62
10 sen ( pi*t/6 - 2*pi/3 ) +57 - 57 = 62 - 57
10 sen ( pi*t/6 - 2*pi/3 ) = 5
10 sen ( pi*t/6 - 2*pi/3 ) / 10 = 5 / 10
sen (pi*t/6 - 2*pi/3) = 0.5
pi*t/6 - 2*pi/3 = pi/6 \(\mbox o\) pi*t/6 - 2*pi/3 = 5*pi/6

Answer 54

Continua a resolver eta ecuacione :)

Answer 55

omg, this is so hard!

Answer 56

Solve the two equations one by one

Answer 57

La primera ecuacion: pi*t/6 - 2*pi/3 = pi/6

Answer 58

Resolve eta ecuacion primero

Answer 59

Suma lo do lado por 2*pi/3

Answer 60

5pi/6 ?

Answer 61

Que te refieras?

Answer 62

bah, i don't get this! :(

Answer 63

pi*t/6 - 2*pi/3 = pi/6
pi*t/6 - 2*pi/3 + 2*pi/3 = pi/6 + 2*pi/3

Answer 64

Complea el tercero paso

Answer 65

what's the 3rd step?

Answer 66

Me refiero "escribe el tercero paso" diculpe

Answer 67

I don't know how to do the next step! :(

Answer 68

Que es "pi/6 + 2*pi/3"?

Answer 69

Is it 5pi/6 ?

Answer 70

Si :)

Answer 71

En que se convertiria la ecuacion?

Answer 72

Yayyyyyyyy!

Answer 73

Escribe el 3o paso?

Answer 74

hmm, i don't know! lol

Answer 75

...

Answer 76

?!?!? :o

Answer 77

In French I'd say "J'en ai marré" but I don't know how I'd say it in Spanish

Answer 78

pi*t/6 - 2*pi/3 = pi/6
pi*t/6 - 2*pi/3 + 2*pi/3 = pi/6 + 2*pi/3
pi*t/6 = 5*pi/6

Answer 79

Puedes encontrar t ahora?

Answer 80

do i have to divide or something ? :o

Answer 81

Si

Answer 82

Multiplica lo do lado por 6

Answer 83

do i have to divide:

pi*t/6 = 5*pi/6 ?

Answer 84

Entonces divide lo do lado por pi

Answer 85

Si

Answer 86

what if i don't have a calculator?!?! D:

Answer 87

...

Answer 88

pi*t/6 - 2*pi/3 = pi/6
pi*t/6 - 2*pi/3 + 2*pi/3 = pi/6 + 2*pi/3
pi*t/6 = 5*pi/6
pi*t = 5*pi
t = 5

Answer 89

No nececitas un calculador

Answer 90

OHH! I just had to leave the 5 alone? :O

Answer 91

una calculadora*

Answer 92

Si

Answer 93

WOW! are we done?!?!?! :O

Answer 94

No

Answer 95

Porque hay 2 repueta

Answer 96

which one? :o

Answer 97

Has resuelta solo la 1a ecuacion, te acuerdas que hay 2 ecuacione?
