Si tomas sale de Ixtapa a las 6:00 am rumbo a Morelia a una velocidad de 70 kmxh ,a la misma hora Claudia sale de Morelia rumbo a Ixtapa a una velocidad de 40 kmxh si entre Morelia e Ixtapa hay una distancia de 660km a que distancia de Morelia se encontraran?
Answer:
El encuentro se producirá a 240 km de Morelia
Step-by-step explanation:
Velocidades Relativas
Este es un caso donde las velocidades son sumativas, pues ambos móviles van a su encuentro mútuo. La distancia total de 660 km será cubierta por ambos móviles con una velocidad relativa de 70 km/h + 40 km/h = 110 km/h
Ya que :
[tex]\displaystyle v=\frac{x}{t}[/tex]
Tenemos que
[tex]\displaystyle t=\frac{x}{v}[/tex]
[tex]\displaystyle t=\frac{660}{110}= 6 \ h[/tex]
Tomás anda a 70 km/h, así que en 6 horas recorre
[tex]x_t=6\times 70 = 420\ Km[/tex]
Claudia anda a 40 km/h, así que en las mismas 6 horas ha recorrido
[tex]x_c=6\times 40 = 240\ Km[/tex]
Se puede decir entonces, que el encuentro se producirá a 240 km de Morelia
Answer:
[tex]\large\boxed{\large\boxed{240km}}[/tex]
Explanation:
Since the question is in Spanish, I will give you the answer in Spanish.
En el punto de encuentro las distancias recorridas por Tomás y Claudia suman la distancia que existe entre Ixtapa y Morelia.
La distancia que recorre cada uno es igual al producto de su velocidad por el tiempo de recorrido.
Para Tomás esto es:[tex]distancia=velocidad\times tiempo\\ \\ d_{Tomas}=70km/h\times t[/tex]
Para Claudia la ecuación es:[tex]distancia=velocidad\times tiempo\\ \\ d_{Claudia}=40km/h\times t[/tex]
Los tiempos, [tex]t[/tex] , son los mismos al momento de encuentro, así que puedes crear una ecuación con una sola incógnita:
[tex]d_{Tomas}+d_{Claudia}=660Km=70km/h\times t+40km/h\times t[/tex]
Puedes obviar las unidades para resolver la ecuación:
[tex]660=70t+40t\\ \\ 660=110t\\ \\ 660/110=t\\ \\ 6=t\\\\ t=6[/tex]
El resultado es en horas: t = 6 horas.
Para encontrar la distancia remplaza el tiempo en la ecuación de Claudia, puesto que ella salió desde la ubicación de Morelia:[tex]d_{Claudia}=40km/h\times t=40km/h\times6h=240km[/tex]
Y esa es la respuesta. Se encontrarán a 240 km de Morelia.
Express each ratio as a fraction in simplest form. A 26:169 B 36 to 78
The ratios 26:169 and 36 to 78, when expressed as fractions in simplest form, are 2/13 and 6/13, respectively, after identifying and dividing by their greatest common factors.
The task is to express each ratio as a fraction in its simplest form. Let's tackle each ratio one at a time.
A. 26:169
To convert the ratio 26:169 into a fraction in simplest form, we observe that both numbers are divisible by their greatest common factor (GCF), which is 26. Dividing both terms by 26, we get 1/6.5. However, to express this in terms of whole numbers, multiplying numerator and denominator by 2 gives us 2/13, which is the fraction in its simplest form.
B. 36 to 78
For the ratio 36 to 78, first, we convert it into fraction form, which is 36/78. The GCF of 36 and 78 is 6. Dividing both the numerator and the denominator by 6, we get 6/13. Therefore, the simplest form of the ratio 36 to 78 is 6/13.

- 4(x – 4) – 3 = 12 + 6x
answer:
1/10 as a fraction or if you want it as a decimal it would be 0.1
step-by-step explanation:
-4(x-4)- 3=12+6x after seeing you multiply -4 by x and -4
and you would get
-4x+0-3=12+6x and then you distribute all the way and you would get
1/10 or if you dont want a fraction and want a decimal is would be 0.1
Answer:
x=1/10 or x=0.1
Step-by-step explanation:
Multiply the parenthesis by 4 (-4x+16-3=12+6x)then subtract the numbers (16-3=13) then move the variable to the left side and change its sign (-4-6x+13=12 to -4x-6x=12-13) then add the terms (-4x-6x=12-13 to -10x=12-13) and get the difference (-4x-6x=12-13 to -10x=-1) then divide bothe sides of the equation by -10 then your answer would be x=1/10
catherine is paying off a $2400 loan by making equal payments over a 12-month period until the loan is paid. express the amount of debt remaining as a function of time in months
Answer:$200 per month is spent.
Step-by-step explanation:
$2400 divided by 12 = $200
The amount of debt remaining as Catherine pays off her $2400 loan over 12 months is expressed by the function D(t) = 2400 - 200t, where t is the time in months.
Explanation:Catherine is paying off a $2400 loan by making equal payments over a 12-month period until the loan is paid. To express the amount of debt remaining as a function of time in months, let's denote the amount of debt remaining as D(t), where t is the time in months.
Since she is making equal payments over 12 months, the total amount she needs to pay each month is $2400 divided by 12 months, which is $200 per month. Therefore, the function that represents the amount of debt remaining at any time t is given by : D(t) = 2400 - 200t
This linear function shows that for each month that passes, $200 is subtracted from the original loan amount of $2400, representing the payments made towards the loan. Thus, after t months, the amount of debt remaining is calculated by subtracting $200 times the number of months from the initial loan amount.

Answer:
π
Step-by-step explanation:
The integral decomposes into the sum ...
[tex]\displaystyle\int_{-2}^2{\left(x^3\cos{\dfrac{x}{2}}\right)\sqrt{4-x^2}}\, dx+\dfrac{1}{2}\int_{-2}^2{\sqrt{4-x^2}}\, dx[/tex]
The first term of this sum is the integral of an odd function, so is zero. The second term of this sum is 1/2 the area under a semicircle of radius 2, so is ...
A = (1/2)(1/2)π·2² = π
The value of the integral is π.
3 x + 2 (4 + 6 x ) =113
Answer:
x=7
Step-by-step explanation:
3x + 2(4 + 6x)= 113
you multiply 2 to 4 that gives you 8 and 2 to 6 that gives you 12x because the 6 has x on it
so it will be 3x + 8 + 12x= 113 then you add 3x to 12x
then you would have 15x+8=113 then subtract 8 to 113 then divide that number to 15 and you get x=7

Solve linear systems by Multiplying
Step-by-step explanation:
The given system of linear equations:
x - 2y = 8 ........ (1)
and 4x + y = 5 ........ (2)
To find, the values of x and y = ?
Multiplying equation (2) by 2, we get
2(4x + y) = 5 × 2
⇒ 8x + 2y = 10 ........ (3)
Adding equations (1) and (3), we get
x - 2y + (8x + 2y) = 8 + 10
⇒ x - 2y + 8x + 2y = 8 + 10
⇒ 9x = 18
⇒ x = 2
Put x = 2 in (1), we get
2 - 2y = 8
⇒ 2y =2 - 8
⇒ 2y = - 6
⇒ y = - 3
∴ x = 2 and y = - 3
y=11 + x
5x+2y= -6

⇔y=-2
Therefore x=2 and y=-2
A pair of shoes usually sells for $62. If the shoes are 40% off, and sales tax is 7%, what is the total price of the shoes, including tax?
Answer:
$39.80
Step-by-step explanation:
If the price is reduced by 40%, it is 100% -40% = 60% of what it was. If 7% tax is added to that, the result is 100% +7% = 107% of the sale price. The final price is ...
$62 × 0.60 × 1.07 = $39.80

Find the volume of the right circular cylinder when the circumference of it’s circular base is 44 cm and It’x height is 10 cm.
The volume of the cylinder is [tex]1539 cm^3[/tex]
Step-by-step explanation:
The volume of a cylinder is given by the equation
[tex]V=\pi r^2 h[/tex]
where
[tex]\pi r^2[/tex] is the area of the base, with r being the radius
h is the height
For the cylinder in this problem we know:
h = 10 cm (height)
c = 44 cm (circumference of the base)
The circumference is given by
[tex]c=2\pi r[/tex]
So the radius is
[tex]r=\frac{c}{2\pi}=\frac{44}{2\pi}=7 cm[/tex]
Therefore, the volume of the cylinder is:
