A ramp is being constructed with wood and then filled with concrete. How many cubic get of concrete will be needed to complete the ramp?

The cubic volume of concrete needed to complete the ramp is 360 ft³

Step-by-step explanation:

We note that the ramp shape is that of a right ngled triangular cube with dimensions

Height = 10 ft

Base = 12 ft

Width = 6 ft

The amount of concrete to fill the ramp is approximately the volume of the ramp.

Volume of ramp = volume of triangular prism = 0.5×Base ×Height  × Width

Volume of ramp = 0.5×12×10×6 = 360 ft³.

The cubic volume of concrete needed to complete the ramp = 360 ft³.

step-by-step explanation:

there are 36 inches in a yard

25 : 36 = 0.69 yards (you can round to 0.70)

check above link.

graphically?   well, you graph them both, the solutions is where they both intersect each other, since there are two solutions, meaning they will meet twice, or namely the linear will run into the quadratic curve twice, and where they meet, those x,y coordinates are the solutions to the system.
