The length of the bridge is the distance from the beginning to the end.
<em>The distance b between each beam is 9ft.</em>
Let:
<em /><em> I-Beam</em>
<em /><em> distance between I beam and the bridge</em>
<em /><em> distance between each I beam</em>
<em />
Given that:
<em /><em> --- length of the bridge</em>
<em />
From the diagram (see attachment), there are: 6 I-beams.
So, the length of the 6 I-beams is:
There are 2 I-beams beside the bridge
So, the distance between the 2 I-beams and the bridge is:
There are 5 spaces between the I-beams
So, the length of the total spaces is:
The total length is:
So, we have:
Collect like terms
Convert inches to feet
Divide both sides by 5
<em>Hence, the distance (b) between each beam is 9ft.</em>

Answer:
301.44 mm
Step-by-step explanation:
Diameter of the inside ring of a packing tape = 80 mm
The tape surrounding the ring is 8 mm beyond the ring which means the diameter of the ring including the surrounding will be:
80 + 8 + 8 = 96 mm
and its radius will be = 96/2 = 48.
To find the distance around the outer edge of the tape, we need to calculate the circumference for the ring with the tape on it.
<em>Circumference = </em>
Circumference = 2 x 3.14 x 48 = 301.44 mm
Therefore, the distance around the outer edge of the tape is 301.44 mm.
A. Always because imagine a line where one is y=x and the other is y=-x+1. The point of intersection would be (1,1)
