Cada estudiante debe pagar 2.88 pesos para consumir 3 rebanadas.

<h3>Como determinar el monto a contribuir por cada estudiante en una convivencia</h3>

Si sabemos que existen 52 alumnos que quieren comer 3 rebanadas, entonces tenemos que el total requerido de rebanadas es de 156 rebanadas.

Además, si dos pizzas tienen 16 rebanadas y cuestan 150 pesos, entonces el número de rebanadas dividido por el par de cajas es 1.025 pares. Por ende, quedarían 4 rebanadas sobrantes que pueden ser compartidas por alguien más o vendidas a alguien más a cambio de una tarifa <em>módica</em>.

Por último, el monto a pagar por cada estudiante es el precio de la oferta dividido el número de estudiantes. En consecuencia, cada estudiante debe pagar aproximadamente 2.88 pesos.  

Cada estudiante debe pagar 2.88 pesos para consumir 3 rebanadas. \blacksquare

What is the equation of the quadratic graph with a focus of (8, −8) and a directrix of y = −6?
yarga [219]
The vertex is exactly half way between directrix and focus. In this case the vertex is (8,-7)
               (h,k)

P is the distance between the vertex and either the directrix or focus,  in this case p = 1. 

a = 1/(4p)  or 1/(4*1) or 1/4

write the equation in vertex form

y = a(x-h)^2 + k

y = 1/4(x-8)^2 -7

PLEASE HELP!
leva [86]

Answer:

B. 56°

Step-by-step explanation:

We are given that m∠R is 66° and m∠T is 122°.

We can apply the supplementary rule since ∠S and ∠T are a linear pair. So, we can use ∠T to find ∠S through 180° - 122° = 58°.

Now, we can use ∠R and ∠S to find ∠Q.

66° + 58° = 124°

180° - 124° = 56°
