if the ratio of the volume of two cubes is 1 : 8 , then find the ratio of the total surface area of the two cubes

vivado [14]

Answer:

V = L^3 where v is volume and L the length of one side

A = 6 * L^2 total area of cube with side L

A = 6 * V^2/3 area of cube expressed in V

A2 / A1 = (V2 / V1)^2/3 6 cancels

A2 / A1 = 8^2/3 = 4 ratio of areas

Find Lowest common factor of following questions . 56, 42, 28

Montano1993 [528]

Answer:

$\boxed{\textsf{ The LCM of 56 , 42 , 28 is \textbf{ 168}.}}$

Step-by-step explanation:

We need to find out the LCM of 56 , 42 , 28 . So Lowest Common Multiple known as LCM is the lowest multiple which is divisible by all the numbers whose LCM is taken out . It can we done by two methods. Both of which are discussed in the attachment .

For complete solution kindly refer to the attachment .

bearhunter [10]

Answer:

Step-by-step explanation:

The given equation is expressed as

y = 1/(x - 2)

We will assume values for x and determine the corresponding values for y. Therefore,

When x = 0, y = 1/(0 - 2) = - 1/2

When x = 1, y = 1/(1 - 2) = - 1

When x = 2, y = 1/(2 - 2) = 0

When x = 3, y = 1/(3 - 2) = 1

When x = 4, y = 1/(4 - 2) = 1/2

To plot the graph, we would choose a suitable scale for the x and y axis of the graph.

Let 2 cm represent 1 unit on the vertical axis.

Let 2 cm represent 0.5 unit on the x axis.

The graph is shown in the attached photo
