The welder needs to cut off 9 3/8 inches from the longer piece.
To determine how much the welder needs to cut off from the longer piece of pipe, we need to find the difference between the lengths of the two pieces.
Given that the longer piece is 28 1/8 inches and the desired length is 18 3/4 inches, we can subtract the desired length from the longer piece's length:
28 1/8 - 18 3/4 = 9 3/8
Therefore, the welder needs to cut off 9 3/8 inches from the longer piece of pipe.

Answer: x = , 0,
Step-by-step explanation:
To find the zeros, we will find the solutions to this equation that make it equal 0. This is a cubic function, so we can assume that there will be three solutions.
Given:
Set the functionequal to 0:
Subtract:
Multiply both sides of the equation by 5:
Factor the polynomial:
Solve with the zero product property:
0 = 3x 0 = 2x - 3 0 = 2x + 3
0 = x 3 = 2x -3 = 2x
x = 0 x = x =
The slope is equivalent to the rise over run. Since the slope of the bike ramp is ¼, the rise is equivalent to 1 and the run is equivalent to 4. To get the angle of the bike ramp make with the ground, let us use the equation tanθ= rise/run.
Therefore, tanθ= ¼.
Θ=tan-1 (1/4)
So the angle of the bike ramp is Θ= 14degrees
