What is the EDGE LENGTH of a cube with VOLUME 27/64 cubic units?

Effectus [21]

Step-by-step explanation:

Let edge length of cube be x units.

$volume \: of \: cube = \frac{27}{64} \\ \\ \therefore \: {x}^{3} = \frac{27}{64} \\ \\ \therefore \: {x}^{3} = \frac{ {3}^{3} }{ {4}^{3} } \\ \\ \therefore \: {x}^{3} = (\frac{ {3}}{ {4} } )^{3} \\ \\ \therefore \: {x} = \frac{ {3}}{ {4} } \\ \\ \therefore \: {x} =0.75 \: {unit}$

Hence, length of edge of cube = 0.75 units

Find a solution to the following system of equations. -3x+3y=-9 -3x+y=7

V125BC [204]

Answer:

(-5, -8)

Step-by-step explanation:

-3x+3y=-9

-3x+y=7

----------------

simplify -3x+3y=-9 into x-y=3

----------------------------------------

y=x-3

-3x+y=7

------------

-3x+(x-3)=7

-3x+x-3=7

-2x-3=7

-2x=7+3

-2x=10

x=10/-2=-5

y=-5-3=-8

x=-5, y=-8
