Answer: Erin needs to rent 15 chairs

Step-by-step explanation:

Hi, we have to write an equation for each rental's cost.

<em>A-1 Rental charges $1.33 per chair, plus $64.42 for the tent. </em>

<em>Tonka Tents charges $1.58 per chair, plus $60.67 for the tent. </em>

  • A-1 Rental's Cost = 1.33x+64.42
  • Tonka Tents Cost = 1.58x+60.67

Where x is the number of chairs.

If both costs are equal:

A-1 Rental's Cost = Tonka Tents Cost

So:

1.33x+64.42 = 1.58x+60.67

Solving for x:

64.42-60.67 = 1.58x-1.33x

3.75 = 0.25x

15 =x

A box contains 10 tags, numbered 1 through 10, with a different number on each tag. A second box contains 8 tags, numbered 20 th
blagie [28]

Answer:

E) 29.0

Step-by-step explanation:

The value of the sum is obtained from 2 independent experiments: the value of the number of the first box X₁ and the value of the number of the second box X₂.

The expected value of a draw is the average of all its values, so E(X₁) = (1+2+3+4+5+6+7+8+9+10)/10 = 5.5 and E(X₂) = (20+21+22+23+24+25+26+27)/8 = 23.5

Hence, E(X₁+X₂) = E(X₁)+E(X₂) = 5.5+23.5=29

Sabiendo que lo ancho de un terreno rectangular mide 24.7 m y que su perímetro es de 131.8 m. ¿Cuánto mide cada uno de sus lados
nadya68 [22]

Answer:

El perímetro de un terreno rectangular mide 48 m . Calcula sus dimensiones si el largo es el doble que el ancho.

Respuesta:

De largo mide 16m

De ancho mide 8m

Explicación paso a paso:

Perímetro = número de lados multiplicado por longitud del lado.

Formula: P = 2(a + b)  o    P = 2b + 2h

Donde: P = Rectángulo del perímetro

           a y b = Longitudes de lados

Asignamos las variables:

Largo = 2x

Ancho = x

Utilizamos la formula:

2(x) + 2(2x) = 48

2x + 4x = 48

6x = 48

x = 48/6

x = 8m  (ancho)

2x

2(8)

16m (largo)
