The surface area of a cube is:

A=6s^2 so we can say:

s=√(A/6)=(A/6)^(1/2)

The volume of  a cube is:

V=s^3, using s found above we have:

V=(A/6)^(1/2)^3

V=(A/6)^(3/2), and A=486 so

V=(486/6)^(3/2)

V=81^(3/2)

V=729 m^3

The answer is D. To help find the answer, you can remember an easy rule. The rule is if you're subtracting a positive number from a negative number, it will always be negative thus eliminating any answers that are positive.

Leonardo wrote an equation that has an infinite number of solutions. One of the terms in Leonardo’s equation is missing, as show
Lady bird [3.3K]

Let us suppose missing term is y

so it becomes - ( x-1) + 5 = 2 ( x+3) - y

let us now try solving it for x ( in terms of y )

-x + 1 + 5 = = 2x + 6 - y

-x + 6 = 2x + 6 -y

6 + y = 2x + 6 +x

y = 3x

y / 3 = x

but x is given to be infinite . let us try placing y= the given options

x= x/3 which is not possible

x= 3x/3 which is giving valid statement

x= 1/3 which is a finite value

x= 5/3 again a finite value

so it is only y= 3x which could be the answer

Answer : option second that is 3x

How can you determine which variable is dependent and which variable is independent
padilas [110]

MrBillDoesMath!

Answer:  The dependent variable depends on another variable for its value. For example, if  y = 2x,  setting x = 1 forces y= 2.; setting x = 10, forces y =20.  There are no other possibilities for y once x ids chosen. So y is the dependent variable and x is the independent one. You can pick values for the independent variable (x) but no so for the dependent one.
