The point-slope form:
We have the points (-5, 15) and (20, 25). substitute:
Answer:
point-slope form: 
slope-intercept form: 
standard form: 
well, you saw it on the previous exercise, 8.25 x 10⁻⁶, it <u>looks</u> like 8.25 is some value between 1 and 10, but is not really, the 10⁻⁶ is disguising that is really much smaller than that, in fact much smaller than even 1.
Answer:
4 and 1/2
Step-by-step explanation:
7x + 2 +x = 8x + 2
8x + 2 = 4(2x + 1/2)
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.
