A truck can be rented from company A for $100 a day plus $0.20 per mile. Company b charges $80 a day plus $0.30 per mile to rent

Fittoniya [83]

Answer:

2000

Step-by-step explanation:

A(m) = 100 + 0.20m

B(m) = 80 + 0.3m

---------------------------

For company A to have a better deal, the truck must be driven more than __ miles per day.

Solve::

100 + 0.2m < 80 + 0.3m

-------

20 < 0.1m

m > 2000/1 = 2000 miles

---------------

2500 mi

Un terreno ha sido cultivado con tres variedades de claveles. La sexta parte ha sido sembrada por

Minchanka [31]

Answer:

1) Se siembra cinco doceavas partes del terreno con claveles rojos y amarillos, 2) Se siembra siete doceavas partes del terreno con claveles blancos.

Step-by-step explanation:

El enunciado se encuentra incompleto. La pregunta faltante es:

2 ¿Qué parte del terreno corresponde a los claveles blancos?

1) Sea $A$ el área total sembrada con los tres tipos de claveles. Entonces, las áreas sembradas con claveles rojos y claveles amarillos son $\frac{1}{6}\cdot A$ y $\frac{1}{4} \cdot A$ , respectivamente.

El área sembrada con claveles rojos y amarillos se obtiene al sumar las áreas correspondientes, es decir:

$x = \frac{1}{6}\cdot A + \frac{1}{4}\cdot A$

$x = \left(\frac{1}{6}+\frac{1}{4}\right)\cdot A$

$x = \left(\frac{4+6}{24} \right)\cdot A$

$x = \frac{10}{24}\cdot A$

$x = \frac{5}{12}\cdot A$

Se siembra cinco doceavas partes del terreno con claveles rojos y amarillos.

2) El área sembrada con claveles blancos se obtiene al sustraer el área obtenida en el punto anterior del área total. Esto es:

$x = A - \frac{5}{12}\cdot A$

$x = \left(1-\frac{5}{12} \right)\cdot A$

$x = \left(\frac{12}{12}-\frac{5}{12} \right)\cdot A$

$x = \left(\frac{12-5}{12} \right)\cdot A$

$x = \frac{7}{12}\cdot A$

Se siembra siete doceavas partes del terreno con claveles blancos.
