7 0

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

\frac{250-70}{2}=x

250-70=180

180/2=90

so 90 couples or 180 ppl

hope this helps

kvasek [131]
12 muffins for 4.80 is the better deal.



Explanation: the ratio of $ to muffin for the first deal is .40:1 which is 40 cents per muffin. Compare this to the second deal’s ratio, .45:1, or 45 cents per muffin, which is higher. Thus, the first deal is better

se quiere pintar una pared en forma de hexágono regular y se sabe que cada lado mide 3m y que su apotema es de 2,8m cual es el a
qwelly [4]

Answer:

El área total a pintar será:

A_{tot}=25.2\: m^{2}

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:

A_{t1}=\frac{b*a}{2}

b es la longitud de la base (b=3 m)

a es la apotema, osea la altura del triangulo (a = 2.8)

A_{t1}=\frac{2.8*3}{2}

A_{t1}=4.2\: m^{2}

Ahora, solo debemos mutiplicar ese valor por 6 para determianr el área total de la pared.

A_{tot}=25.2\: m^{2}

Espero te haya sido util!
