Problema de capacidades Una empresa aceitera ha envasado 3000 litros de aceite en 1200 botellas de dos y de cinco litros. ¿Cuánt
mariarad [96]

Answer:

Hay 200 botellas de 5 litros y 1000 botellas de 2 litros.

Step-by-step explanation:

Un sistema de ecuaciones lineales es un conjunto de dos o más ecuaciones de primer grado, en el cual se relacionan dos o más incógnitas.

Resolver un sistema de ecuaciones consiste en encontrar el valor de cada incógnita para que se cumplan todas las ecuaciones del sistema.

En este caso, las variables a calcular son:

  • x= cantidad de botellas de 2 litros.
  • y= cantidad de botellas de 5 litros.

Una empresa aceitera ha envasado 3000 litros de aceite en 1200 botellas de dos y de cinco litros. Entonces es posible plantear el siguiente sistema de ecuaciones:

\left \{ {{2*x+5*y=3000} \atop {x+y=1200}} \right.

Existen varios métodos para resolver un sistema de ecuaciones. Resolviendo por el método de sustitución, que consiste en despejar o aislar una de las incógnitas y sustituir su expresión en la otra ecuación, despejas x de la segunda ecuación:

x= 1200 - y

Sustituyendo la expresión en la primer ecuación:

2*(1200 - y) + 5*y=3000

Resolviendo se obtiene:

2*1200 - 2*y + 5*y= 3000

2400 +3*y= 3000

3*y= 3000 - 2400

3*y= 600

y= 600÷3

y= 200

Reemplazando en la expresión x= 1200 - y:

x= 1200 - y

x=1200 -200

x= 1000

<u><em>Hay 200 botellas de 5 litros y 1000 botellas de 2 litros.</em></u>

Hannaford sells two sizes of cheerios cereal. The smaller box contains 9 ounces and
svlad2 [7]

Quantity of cheerios cereal in the smaller box Hannaford sold = 9 ounces

Cost of nine ounces of cheerios cereal = $2.50

Cost of one ounce of cheerios cereal :

= 2.50 \: \div  \: 9

=\color{plum}\$ 0.27

Cost of one ounce of cheerios cereal in the smaller box = $0.27

Quantity of cheerios cereal in the larger box Hannaford sold = 20 ounces

Cost of nine ounces of cheerios cereal = $3.79

Cost of one ounce of cheerios cereal :

= 3.79 \div 20

=\color{plum} \$0.18

Cost of one ounce of cheerios cereal in the larger box = $0.18

Difference in their cost per ounce :

= 0.27 - 0.18

=\color{plum}\bold{\$ 0.09}

Therefore, the difference in cost in dollars per ounce between the two sizes = $0.09

The diameter of a cylinder is 4 centimeters. The height is 12 centimeters. Using 3.14 for pi, what is the volume of the cylinder
Dovator [93]

Answer:

The volume of the cylinder with given height and radius is 150.72 centimeters³ .

Step-by-step explanation:

Given as :

the height of cylinder = H = 12 centimeters

The diameter of cylinder = D = 4 centimeters

So The radius of cylinder = R = \dfrac{\textrm Diameter}{2}

Or, R = \frac{4}{2}

I.e R = 2 cm

The volume of cylinder is given as V = \pi×R²×H

where R is the radius and H is the height

So, V = 3.14×(2)²×12

Or, V = 3.14×48

∴ V = 150.72 centimeters³

So, The volume is 150.72 centimeters³

Hence The volume of the cylinder with given height and radius is 150.72 centimeters³ . Answer
