Answer:

Definamos R como la "velocidad" a la que una persona puede construir la barda dada.

Supongamos que la persona necesita un tiempo T para construir la barda, entonces tenemos la relación:

R*T = 1 barda.

Si dos personas trabajan juntas la velocidad de trabajo va a ser (R + R), y sabemos que ellos pueden completar el trabajo en 2 días, entonces:

(R + R)*2 días = 1 barda

(2*R)*2 días = 1 barda

(2*R) = (1/2) barda por día

R = (1/2)*(1/2) barda por día = (1/4) barda por día.

Esto significa que una persona puede completar un cuarto de la barda en un día de trabajo.

Ahora queremos saber cuantas personas se necesitan para construir una barda en solo medio día, entonces debemos resolver:

(N*R)*0.5 días = 1 barda

Donde N es el número de personas que queremos obtener.

(N* (1/4) barda por día)*0.5 días = 1 barda

N*(1/4) barda por día = (1/0.5) bardas por día = 2 bardas por día

N = 2/(1/4) = 2*4 = 8

N = 8

Se necesitan 8 personas para construir una barda en medio día.

⦁ A total of 640 people voted in an election. The circle graph shows the results. ⦁ How many people voted for Goron? Show your w
Bezzdna [24]

Circle graphs or pie charts are used to represent data in percentages or proportions

  • 192 voted for Goron
  • 288 voted for Smith or Fishman

<h3>People that voted for Goron</h3>

The total number of votes is given as:

Total = 640

The circle chart is not given.

So, we make use of an assumed value

Assume 30% voted for Goron

The number of people would be:

Goron = 30% * 640

Evaluate

Goron = 192

Hence, 192 voted for Goron using the assumed value

<h3>People that voted for Smith or Fishman</h3>

Assume 45% voted for Smith or Fishman

The number of people would be:

Smith or Fishman = 45% * 640

Evaluate

Smith or Fishman = 288

Hence, 288 voted for Smith or Fishman using the assumed value
