Answer:
Step-by-step explanation:
6. Soil volume = area * height = 1/2*4*4*2.5 = 20 cubic ft
7. Concrete volume = length * width * height = 1.8*1.8*3 = 9.72 cubic ft
Block weight = 95*9.72 = 923.4 lb
8. It is unclear but let's assume the ramp consists of 5 pieces.
The total area = 4*6+3.5*(4+6+7.2) = 84.2 sq ft
So it will require a minimum of 85.2/(4*2) = 10.65 or 11 sheets of plywood
the skateboard ramp only needs 3 pieces: 2x triangle of 4' by 6' and 1x rectangle of 3.5' by 7.2'.
the 2x triangle require 4x6/4x2 = 3 sheets of plywood
the rectangle require 3.5x7.2/4x2 = 3.15 ~4
so minimum is 7 sheets
a+4b-24
x = 3/2, 9/2.
Line 3: 36.
Line 6: 3/2.
Last line: 9/2, 3/2.
5184
9 squared is 81 (9 x 9)
8 squared is 64 (8 x 8)
64 x 81 is 5184
The last one!
2^3 is 8 which makes it the greatest value
the radical 4 is 2
the 54% is equal to .54 in decimal form
the 0.030 is the value with the least
