Find the volume of the composite solid. Round your answer to the nearest tenth. PLEASE HURRY!!! A composite solid is shown with a cube placed at the bottom and a half-sphere placed at the top of the edges of the upper plane surface. The length, width, and height of the cube are 8 centimeters respectively.

its either "10" or "70"

the system of inequalities is

step-by-step explanation:

step 1

find the equation of the dashed line

we have the points

(0,0) and (3,1)

the line passes through the origin, so, is a direct variation

find the slope

the equation of the dashed line is

the solution of the inequality a s the shaded area above the dashed line

therefore

the equation of the inequality a is

step 2

find the equation of the solid line

we have the points

(4,0) and (0,4)

find the slope

the equation of the solid line is

the solution of the inequality b s the shaded area below the solid line

therefore

the equation of the inequality b is

step 3

the system of inequalities is

explanation:

remove parenthesis:

=
