Answer:
0.7.
Step-by-step explanation:
x^2 = 0.7x
x^2 - 0.7x = 0
x(x - 0.7) = 0
x = 0, 0.7.
Answer:
33 = r
Step-by-step explanation:
The circumference is given by
C = 2 * pi *r
207.24 = 2 * 3.14 *r
207.24 = 6.28 *r
Divide each side by 6.28
207.24/6.28 = 6.28 r /6.28
33 = r

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.
Answer: The front face has an area of 30 ft2. , The top face has an area of 40 ft2. ,
