<u><em>Answer:</em></u>

The constant of proportionality is 9.5

<u><em>Explanation:</em></u>

The relation we are given between the hours worked and the amount of money received is a direct proportional relation

A direct proportion relation between two quantities means that when one of the them increases, the other would increase with a fixed rate and vice versa

<u>This relation is represented using the following general equation:</u>

y = kx where k is the constant of proportionality

<u>Now, we are given that:</u>

Adrian works 20 hours (x = 20, independent variable) and earns $190 (y = 190, dependent variable)

We substitute with these givens in the general equation and solve for k

<u>This is done as follows:</u>

y = kx

190 = 20k

k = 9.5

This means that the constant of proportionality is 9.5

<u>Additional information:</u>

The constant of proportionality in this problem represents Adrian's hourly rate

<u>The equation is:</u>

Amount earned = Hourly rate * number of hours worked

<u>We have:</u>

y is the amount earned

k is the hourly rate (constant of proportionality)

x is the number of hours worked

<u>The final equation is:</u>

y = 9.5x

Hope this helps :)

Un ingeniero civil a cargo de una obra contrata una cierta cantidad de obreros. Estima que, si le
BabaBlast [244]

Al plantear un sistema de ecuaciones lineales, encontramos que el número de obreros que contrató el ingeniero civil fue 50.

Para encontrar el número de obreros que el ingeniero contrató debemos plantear un sistema de ecuaciones lineales de dos ecuaciones con dos incógnitas, tal como sigue:

M - 1400*x = -8000   (1)

M - 1200*x = 2000   (2)

En donde:

M: es la incógnita igual al monto de dinero del ingeniero

x: es la incógnita igual al número de obreros

De la ecuación (1) tenemos:

M = 1400*x - 8000   (3)

Podemos encontrar el valor de x (número de obreros), introduciendo la ecuación (3) en la ec (2):

1400*x - 8000 - 1200*x = 2000

200*x = 10000

x = 50

El monto de dinero inicial del ingeniero sería entonces (ec 3):

M = 1400*50 - 8000 = 62000

Por lo tanto, el número de obreros que contrató el ingeniero es 50.

If a and b are any two real numbers, than how do you calculate the difference between a-b
Stells [14]
When you're are asking if a and b are any two real numbers then in order to find the difference between the two numbers, you would have to subtract a by b and that would be your difference.

Choose one of the factors of x^3 + 343
djyliett [7]
I've done this test before 

The factor should be x+7 so, none of the above.
