When is the accounting equation used?

Answer:

[tex]m=20c[/tex]

Step-by-step explanation:

Let m represent the total money collected and c represent the amount of cars washed.

We know that the money collected is directly proportional to the number of cars washed. So, we can write the following equation:

[tex]m=kc[/tex]

Where k is a constant.

We know that the money collected after 7 car washes is $140. So, let's find our k by substituting 140 for m and 7 for c. This yields:

[tex]140=7k[/tex]

Find k. Divide both sides by 7:

[tex]k=20[/tex]

So, the value of k is 20.

We can now substitute k back into our direct variation equation:

[tex]m=20c[/tex]

This means that every car costs $20 to wash.

And we're done!

Answer:

[tex]d=5[/tex]

Step-by-step explanation:

Distance Formula: [tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

Simply plug in the 2 coordinates into the distance formula to find distance d:

[tex]d=\sqrt{(7-3)^2+(7-4)^2}[/tex]

[tex]d=\sqrt{(4)^2+(3)^2}[/tex]

[tex]d=\sqrt{16+9}[/tex]

[tex]d=\sqrt{25}[/tex]

Answer:

Ok, primero Agustín camina a 5km/h.

Cuando el recorre 7km, el regresa.

El tiempo en el que sucede esto es a:

7km/5km/h = 1.4 h

La ecuación para Agustín es:

A(t) = 5km/h*t                                     para  0h ≤ t  ≤ 1.4h           (ida)

A(t) = 7km -  5km/h*(t - 1.4h)              para 1.4h ≤ t.                     (vuelta)

Hacemos lo mismo para Barbara:

7km/3km/h = 2.5h

La ecuación para ella es:

B(t) = 3km/h*t                                    para 0h ≤ t  ≤ 2.5h              (ida)

B(t) = 7km -  3km/h*(t - 2.5h)              para 2.5h ≤ t.                     (vuelta)

a)  ¿a qué distancia de la partida se encuentra con Bárbara?

Tenemos que ver cuando A(t) = B(t).

Para ello comparamos la vuelta de Agustín con la ida de Barbara.

7km -  5km/h*(t - 1.4h) = 3km/h*t  

7km - 5km/h*T + 7km = 3km/h*T

14km = 8km/h*t

14/8 h = 1.75h = t.

Entonces la posición en la que se encuentran es:

B(1.75h) = 3km/h*1.75h = 5.25km

Ellos se encuentran a 5.25 kilómetros de el punto de partida.

b)  Si en el momento del encuentro también Bárbara emprende el regreso

(Es decir, en este momento Barbara comienza a regresar).

Entonces ella para regresar al punto de inicio tiene que recorrer 5.25km con una velocidad de 3km/h.

Tb = 5.25km/3km/h = 1.75h

Barbara tarda 1.75 horas en regresar.

Agustín también tiene que recorrer 5.25 km para regresar, pero su velocidad es 5km/h.

Ta = 5.25km/5km/h = 1.05h.

La diferencia entre los tiempos es:

Tb - Ta  =1.75h - 1.05h = 0.7h

Entonces Barbara llega al punto de partida 0.7 horas después que Agustín.

Pero queremos esto en minutos.

1 hora = 60 minutos.

0.7 horas = 0.7*(60 min) = 42min

Barbara llega 42 minutos después que Agustín.

Step-by-step explanation:

Answer:

 x = 45

Step-by-step explanation:

AB // CD,

∠AB0 + ∠COB = 180  {Co interior angles}

   75 + ∠COB = 180

             ∠COB = 180 - 75 = 105

∠DOE =∠COB   {Vertically opposite angles}

∠DOE = 105

In ΔDOE,

x + 30 + 105 = 180    {angle sum property of triangle}

      x + 135 = 180

                x = 180 - 135

                x = 45

Answer:

4.074 hours

Step-by-step explanation:

r =

The formula for speed = Distance × Time

Hence,

Let the outbound speed = r

return trip speed = r + 25x/100 = 125r/100 = 1.25r

Note that: 9 hours and 20 minutes = 9.167

Let t1 and t2 be the time taken to travel on way and return journey.

t1 + t2 = 9 hr 10 min = 9.167 hrs

Hence:

2688/r + 2688/1.25r = 9.167

LCM(1.25r)

(2688 × 1.25) + 2688 /1.25r= 9.167

3360 + 2688 = 9.167 × 1.25r

6048 = 11.45875r

r = 6048/11.45875

Outbound trip rl = 527.8062615904876mph

Return trip speed = r + 25x/100 = 125r/100 = 1.25r

= 1.25 ×

659.75782699mph

Time for return trip = Distance/Speed

= 2,688 miles/659.75782699mph/

= 4.0742222222 hours

Approximately = 4.074 hours

Answer: Y=7

Step-by-step explanation: if you have to find y then it’s

5y-28=7

   +28+=+28 adding 28 to both sides to have y by itself -28+28=0 & 28+7=35

5y=35 then you divide by 5 on both sides

So it’s y= 7
