Me pueden ayudar por favor?. Un electricista cobra $3 por hora de trabajo y un plomero $1,2 por hora ¿cuantas horas deberá traba
REY [17]

Answer:

El plomero debe trabajar 25 horas para ganar lo mismo que gana el electricista en 10 horas de trabajo ($30).

Step-by-step explanation:

Para esta pregunta debemos seguir los <em>siguientes pasos</em>:

  1. Determinar los datos principales del problema.
  2. Determinar lo que gana el electricista por trabajar 10 horas.
  3. Determinar las horas que debe trabajar el plomero (considerando lo que gana por hora) para ganar lo mismo que gana el electricista por las 10 horas de trabajo.

En lo siguiente emplearemos la notación USD que es equivalente a $ (USD = $).

Primer paso: datos principales del problema

  • Tenemos que un electricista cobra \\ \frac{USD\;3}{hora}.
  • El plomero cobra \\ \frac{USD\;1.2}{hora}.

Segundo paso: ¿cuánto gana el electricista por trabajar 10 horas?

En este caso, <em>multiplicamos lo que gana el electricista por hora, por las 10 horas de trabajo, </em>y obtener lo que gana en esas 10 horas.

\\ \frac{USD\;3}{hora}*10\;horas

\\ \frac{USD\;3*10\;hora}{hora}

\\ USD\;30

De esta manera, el electricista gana $30 por trabajar 10 horas.

Tercer paso: cantidad de horas que debe trabajar el plomero para ganar $30, considerando lo que gana por hora ($1,2 por hora).

Para determinar el número de horas que el plomero debe trabajar para   ganar $30, podemos escribir la siguiente ecuación:

\\ \frac{USD\;1.2}{hora}*X = USD\;30 [1]

La equación anterior nos dice: ¿qué numero de veces (X) tenemos que multiplicar lo que <em>gana el plomero por hora</em> para que gane $30 (<em>lo mismo que gana el electricista en 10 horas de trabajo</em>)? En otras palabras, la cantidad de horas que tiene que trabajar para ganar $30, considerando que gana $1,2 por hora.

De esta forma, tenemos que despejar <em>X</em> de la ecuación [1], de la siguiente manera, para luego determinar <em>el número de horas que debe trabajar</em>:

\\ \frac{USD\;1.2}{hora}*X = USD\;30

\\ X = \frac{USD\;30}{\frac{USD\;1.2}{hora}}

\\ X = \frac{30}{1.2}\frac{USD}{\frac{USD}{hora}}

\\ X = 25\;horas

Nótese que en las unidades sólo quedan las <em>horas</em> por cuanto \\ \frac{USD}{USD} = 1 y las horas que quedan en el denominador, pasan al numerador, ésto es,  \\ \frac{USD}{\frac{USD}{horas}} = USD*\frac{horas}{USD} = horas.

Por lo tanto, <em>el plomero debe trabajar </em><em>25 horas</em><em> para ganar $30</em> (lo que gana el electricista por 10 horas de trabajo).

El resultado es congruente porque la tasa que cobra por hora de trabajo es mayor para el electricista ($3 por hora) que para el plomero ($1,2 por hora).

Cami goes scuba diving. She descends 18 feet in 3 minutes. Which expressions represent the average rate at which Cami’s position
julsineya [31]

Answer:

6 ft/min

Step-by-step explanation:

Theres a neat trick to note; whenever you say per think of it as a fancy word for divide, because the label is always gonna be a/b (a per b)

Therefore,

the rate of feet per minute will be the feet divided by the minutes;

18 feet in 3 minutes = <u>18</u>/3 <u>ft</u>/min

Therefore the rate is 6 feet per minute.

<u>IF you need an explanation on what average rate implies:</u>

<em>Note; the word average is not prudent to answer as its extraneous, however if there was more data like "Cami descends 18 ft in 3 min and Nami descends 9 ft in 3 minutes; whats the average rate at which they descend" then you'd have to add the two rates up and divide by two.</em>

Hope this helps :)

The length of a rectangle is 22 meters longer than the width. if the area is 2626 square​ meters, find the​ rectangle's dimensio
yawa3891 [41]
L=22w (w=width, l=length)

l*w=2626
Substitute 22w for l, getting 22w^2=2626. Divide by 22 to get 119.36 (and more decimals!), and square root that to get 10.9 (rounded) for the width and 240.4 (rounded) for the length

(06.02) A linear function that represents the number of animals adopted from the shelter is compared to a different linear funct
irga5000 [103]

Answer:

1) These linear functions must not describe a pair of parallel lines.

2) Any intersection of two lines determines a point.

Step-by-step explanation:

Hi there!

Well, since no further details were given. Let's call the linear function that represents the number of animals adopted from the shelter s(x). And

the hours the volunteers work at the shelter each week v(x)

1) These linear functions must not describe a pair of parallel lines.

If these lines intersect, then their slope must be different.

m_{s}\neq m_{v}\\e.g.\\m_{s}=2\\m_{v}=-2

Equal slopes, parallel lines. Parallel lines, no intersection.

Different slopes, then there is an intersection at some point.

2) Any intersection of two lines determines a point. Let's find it.

So to find one common point equalize the two functions, then find the value for the x-coordinate. Plug it in one of the functions, e.g.

2x+2=-2x+2 \rightarrow 4x=0 \therefore x=0\\2(0)+2=2 \Rightarrow (0,2)

At the common point, both functions after inserted the same value in the Domain (x) return the same result for their respective  Range set.
