1 answer:
Answer:
90 couples or 180 ppl
Step-by-step explanation:
lets take "x" as the couples who remained at the party
we start out with 250:
250
but by the time it is 11pm, 70 people have left the party
since it is a couples party we need to divide by two to account for the couples
=x
250-70=180
180/2=90
so 90 couples or 180 ppl
hope this helps

Answer:
El área total a pintar será:
Step-by-step explanation:
Sabiendo el apotema y la longitu de los lados, podemos encontrar el área de un triangulo. Recordemos que, si trazamos rectas del centro del hexágono a los vértices, se formaran 6 triángulos equiláteros.
El área de un triángulo es:
b es la longitud de la base (b=3 m)
a es la apotema, osea la altura del triangulo (a = 2.8)
Ahora, solo debemos mutiplicar ese valor por 6 para determianr el área total de la pared.
