Answer:

C = 60t + 70

Step-by-step explanation:

The total cost of hiring Plumbing Service is given by the equation C = 50t + 70, where C is the total cost in dollar and t is the time in hours.

So, $ 70 is the fixed price and $50 is the rate of charge per hour for the service.

Now if in the next month the rate of charge per hour for the service increased to $60 and the initial charge remains the same then the equation for the total cost of hiring Plumbing Service will become C = 60t + 70. (Answer)

¿Cuál es el área de un rectángulo, sabiendo que su perímetro mide 24 cm y que su base es el triple de su altura?
Brrunno [24]

Answer:

El área del rectángulo es:

27 cm²

Step-by-step explanation:

Consideración:

La formula del perímetro de un rectángulo es:

p = 2(altura + base)

Planteamiento:

24 = 2(a+b)

b = 3a

a = longitud de la altura del rectángulo

b = longitud de la base del rectángulo

Desarrollo:

sustituyendo el valor de la segunda ecuación del planteamiento en la primer ecuación del planteamiento:

24 = 2(a + 3a)

24/2 = 4a

12 = 4a

a = 12/4

a = 3 cm

de la segunda ecuación del planteamiento:

b = 3a

b = 3*3

b = 9 cm

Comprobación:

de la primer ecuación del planteamiento:

24 = 2(3+9)

24 = 2*12

Respuesta:

la formula del área de un rectángulo es:

A = base * altura

A = 9cn * 3cm

A = 27cm²
