Answer:
a =5
Step-by-step explanation:
-26a-3+20a=27
Combine like terms
-6a -3 = 27
Add 3 to each side
-6a -3+3 =27+3
-6a = 30
Divide each side by -6
-6a/-6 = 30/-6
a =5
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: 144.4 yd
Step-by-step explanation:
C= diameter times pi(3.14)
r = 23
d = r2
d = 46 yd
46(3.14) = 144.44
Round 144.44 to nearest tenth
144.44 is 144.4 rounded
C = 144.4 yd
