Roger is paid $50 to sell videos of a play to an audience after the play is preformed.
konstantin123 [22]

Answer:

Roger can earn $510 at most.

Step-by-step explanation:

We are given the function



Which gives the earnings of Roger when he sells v videos. Since the play’s audience consists of 230 people and each one buys no more than one video, v can take values from 0 to 230, i.e.  



That is the practical domain of E(v)

If Roger is in bad luck and nobody is willing to purchase a video, v=0

If Roger is in a perfectly lucky night and every person from the audience wants to purchase a video, then v=230. It's the practical upper limit since each person can only purchase 1 video

In the above-mentioned case, where v=230, then



Roger can earn $510 at most.

Given: △FKL, FK=a
LuckyWell [14K]

Answer:

FL= \frac{a (\sqrt{3} + 1)}{\sqrt{2} }

Step-by-step explanation:

As given  in figure 1 below:

FK = a, m∠F = 45° and m∠L = 30°

Construction: Draw an altitude KE from point K on FL.

Now, In ΔFEK,

FE = EK (Sides opposite to equal angles of a triangle)

Let FE = EK = x  

Now, using pythagoras In  ΔFEK,

(FK)^{2} = (FE)^{2} + (KE)^{2}  

(a)^{2} = (x)^{2} + (x)^{2}

(a)^{2} = 2x^{2}

x = \sqrt \frac{a^{2} }{2} = \frac{a}{\sqrt{2} }

∴ FE = EK = \frac{a}{\sqrt{2} }

Now in ΔEKL, EK = \frac{a}{\sqrt{2} }

Using trigonometry ratio,

TanФ = Altitude\ Base

Tan \theta = \frac{KE}{EL}

Tan 30° = \frac{a/\sqrt{2} }{EL}

\frac{1}{\sqrt{3} } = \frac{a}{\sqrt{2} EL}

EL = \frac{\sqrt{3}a}{\sqrt{2} }

Now FL = FE + EL

FE = \frac{a}{\sqrt{2} } and EL = \frac{\sqrt{3}a}{\sqrt{2} }

∴ FL = \frac{a}{\sqrt{2} } + \frac{\sqrt{3}a }{\sqrt{2} } = \frac{a (\sqrt{3} + 1)}{\sqrt{2} }

Pablo debe ordenar 350 sillas de un salón en filas y columnas. Cada fila tendrá 20 sillas. ¿Cuántas filas completas podrá formar
dolphi86 [110]

Answer:

  • ¿Cuántas filas completas podrá formar? 17 filas
  • ¿Quedará alguna fila incompleta? Si
  • ¿Con cuantas sillas? 10 sillas
  • ¿Cómo representarías con una división el proceso? 350÷20= 17.5

Step-by-step explanation:

La división es una operación matemática que consiste en averiguar cuántas veces un número está contenido en otro número. En otras palabras, dividir es repartir un número en grupos iguales.

En este caso, deseas repartir 350 sillas en filas, en las cuales entran 20 sillas. Entonces, para conocer cuántas filas completas podes formar haces la división: 350÷20= 17.5

Entonces, se podrán formar 17 filas completas y, al ser 17.5 un número decimal, indica que hay otra fila que quedará incompleta.

Para saber cuántas sillas tendrá la fila incompleta podes realizar el siguiente cálculo: 17 filas*20 sillas= 340, que indica que para completar las 17 filas usas un total de 340 sillas. Si tenes 350, entonces en la fila incompleta hay solo 10 sillas (obtenida mediante la operación 350-340= 10) de las 20 que debería haber, faltando otras 10 sillas para completarla.

Finalmente:

  • <u><em>¿Cuántas filas completas podrá formar? 17 filas</em></u>
  • <u><em>¿Quedará alguna fila incompleta? Si </em></u>
  • <u><em>¿Con cuantas sillas? 10 sillas</em></u>
  • <u><em>¿Cómo representarías con una división el proceso? 350÷20= 17.5 </em></u>
