I’m sorry I’m answering this to ask a question
10. The constant of proportionality would be 0.07 because in the equation y=kx 0.07 is substituted for k which stands for the constant of proportionality.
11. The equation is t=45d because for every hour you travel 45 miles (or 90/2, 135/3, etc.)

Answer:
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.
