Resolviendo el sistema de ecuaciones veremos que:

  • niña = 23kg
  • niño = 28kg
  • perro = 18kg.

<h3>¿Como resolver el sistema de ecuaciones?</h3>

Aqui tenemos el sistema de ecuaciones:

Niña + niño = 51kg

Niño + perro = 46 kg

Niña + perro = 41kg

Para resolver esto, lo primero que debemos hacer es aislar una variable en una de las ecuaciones, por ejemplo, podriamos aislar "perro" en la tercera:

perro = 41kg - niña

Ahora reemplazamos eso en la segunda para obtener:

niño + (41kg - niña) = 46kg

niño - niña = 46kg - 41kg = 5kg

niño = niña + 5kg

Ahora logramos obtener la variable "niño" en terminos de la variable "niña". Podemos reemplazar esto en la primera ecuacion del sistema.

niña + niño = 51kg

niña + (niña + 5kg) = 51kg

2*niña = 51kg - 5kg = 46kg

niña = 46kg/2 = 23kg.

Ahora que sabemos esto, usamos las otras ecuaciones para encontrar el peso del niño y el perro:

niño = niña + 5kg = 23kg + 5kg = 28kg

perro = 41kg - niña = 41kg - 23kg = 18kg.

I need some help finding the volume of a sphere with a diameter of 18.6cm. The website says the answer I got from my calculator
777dan777 [17]

Answer:

V = 3,367.6 cm³

Step-by-step explanation:

Diameter of sphere (D) = 18.6 cm

radius (r) = ½(18.6) = 9.3

π = 3.14

Formula for volume of a sphere = ⁴/3πr³

Plug in the values

V = ⁴/3 × 3.14 × 9.3³

V = ⁴/3 × 3.14 × 804.357

V = (4*3.14*804.357)/3

V = 3,367.57463

V = 3,367.6 cm³ (nearest tenth)

Given that weekly demand curve of a local wine producer is p = 50 − 0.1q, and that
rusak2 [61]

Answer:

Z(p) = -10p² + 600p - 6500

Step-by-step explanation:

Demand curve <em>p</em> = 50 - 0.1 <em>q</em>

Total cost function <em>C</em>(<em>q</em>) = 1500 + 10q

where q is the number of bottles produced each day and p is the selling prices per bottle.

Now, <em>p</em> = 50 - 0.1 <em>q</em>

o.1 <em>q = </em>50 <em>- p</em>

<em>q = </em>500 - 10<em>p</em>

Revenue = price × quantity =<em> p × q</em>

= <em>p</em> ( 500 - 10<em>p</em>)

= 500<em> p</em> - 10<em>p²</em>

Profit = total revenue - total cost

Let Profit be Z since profit is function of price, therefore

<em>Z(p) = pq - C(q)</em>

<em>Z</em> (p)=  500<em> p</em> - 10<em>p</em>² - (1500 + 10<em>q</em>)

Substituting the value of q in above expression,

<em>Z(p) </em>= 500 <em>p</em> - 10<em>p</em>² - ( 1500 + 10 (500 - 10<em>p</em>))

<em>Z(p)</em> = 500<em>p</em> -10<em>p</em>² - 1500 -5000 + 100<em>p</em>

<em>Z(p)</em> = -10<em>p</em>² + 600<em>p</em> - 6500

So, the weekly profit as a function of price p is Z(p) = -10p² + 600p - 6500.
