Answer:

Yes, she is almost done

Step-by-step explanation:

We can find the common denominator of these fractions, then add them.

1/3=4/12

1/4=3/12

Then we add the two, and round it up either up or down, depending if it is above 1/2. 6/12 is equal to 1/2, and 4/12+3/12 is 7/12 which is greater than 1/2, so she is almost done.

Whats the total area of covered box with a length of 4ft a width oc 3ft and height of 6 ft
hodyreva [135]
The total area of a box is the sum of all the area of the faces it has. It is also called the surface area. The area of one face of a rectangular box is equal to the product of its length and width. So, the total area would be:

SA = 2lw + 2wh + 2lh
SA = 2(4)(3) + 2(3)(6) + 2(4)(6)
SA = 108 ft^2

En una progresion geometrica el primer termino es 4 ¿ cual debe de ser la razon para que la suma de sus infinitos sea 5?
dem82 [27]

Respuesta:

La proporción común del término puede ser 1/5

Explicación paso a paso:

La fórmula para calcular la suma al infinito de una secuencia geométrica se expresa como:

Sinfty = a / 1-r

Dado

Sinfty = 5

Primer término a = 4

Requerido

Razón común r

Sustituir

5 = 4/1-r

5 (1-r) = 4

5-5r = 4

-5r = 4-5

-5r = -1

r = 1/5

Esto significa que la razón común debe ser 1/5 para que la suma hasta el infinito sea 5
