Answer:

The perimeter of each window is 192 inches.

Step-by-step explanation:

Area = length x width

Width = area / length = 2160/60 = 36 inches

Perimeter = 2length + 2width = (2x60) + (2x36)= 120+72= 192 inches

Answer:

Perimeter = 192 inches

Step-by-step explanation:

Given that:

Area = 2160 inches

length = 60 inches

We have to find perimeter of each window:

First we will find width of window by following formula:

Area = length * width

width = Area/ length

width = 2160/60

width = 36 inches

For finding perimeter we know that:

Perimeter = 2 (length + width)

Perimeter = 2(60 + 36)

Perimeter = 2 (96)

Perimeter = 192 inches

i hope it will help you!

Roy and Sam start solving the equation as follows.
denpristay [2]

Answer:

The correct option is D.

Step-by-step explanation:

The given equation is

-3x+4=5x-6

According to the addition property of equality a=b and a+c=b+c are equivalent equations.

Use addition property of equality, add 3x on both the sides.

-3x+4+3x=5x-6+3x

4=8x-6

Therefore Sam's work is incorrect because he make calculation mistake.

According to the subtraction property of equality a=b and a-c=b-c are equivalent equations.

Use subtraction property of equality, subtract 5x from both the sides.

-3x+4-5x=5x-6-5x

-8x+4=-6

Therefore Roy's work is correct because he used subtraction property.

Option D is correct.

1. Si las notas de Esteban en una asignatura son: 3, 4, 6, 3, 5, 5, 6, 3, 4 y de estas notas se cambia un 6 por un 7, ¿cuál(es)
Andru [333]

Responder:

Media

Explicación paso a paso:

Primero debemos saber que cambiar el valor de 6 a 7 no puede cambiar la mediana y la moda de los datos, ya que la moda es el valor que más ocurre, que es 3, mientras que la mediana es el valor tq en el medio después del reordenamiento.

La única medida de tendencia que cambiará es la media (datos promedio)

Vamos a revisar

Encuentra la media de dos datos originales

Media = 3, + 4, + 6 + 3, + 5 + 5 + 6 + 3 + 4/9

Tamaño de muestra = 9

Media = 39/9

Media = 4,33

Si uno de los 6 se reemplaza por 7, la media se convierte en

Media = 3, + 4, + 6 + 3, + 5 + 5 + 7 + 3 + 4/9

Tamaño de muestra = 9

Media = 40/9

Media = 4,44

Podemos ver que cambió el valor medio. Por tanto, la respuesta correcta es la media.

In a right triangle, the acute angles measure 2x + 50 and 3x degrees. What is the measure of the smallest angle of the triangle?
andrezito [222]
Since this is a right triangle the two acute angles must sum to 90 degrees because a triangle's angles must sum to 180 degrees. 

2x+50+3x=90

5x+50=90

5x=40

x=8

So the smallest angle is 3x=3*8=24°
