Answer:
398.71 ft
Step-by-step explanation:
Length of rebar = 18 inches = 1.5 ft
Elevation = 393.66 ft
Reading of backsight on Benchmark= 7.56 ft
Rod reading = 1.10 ft
<em>First step : determine height of Instrument been used</em>
= elevation + backsight on Benchmark
= 393.66 + 7.56 = 401.22 ft
<em>Elevation of top of rebar </em>
= 401.22 - 1.01 = 400.21 ft
Finally determine the elevation of the top of the pipe
= 400.21 - length of Bar
= 400.21 - 1.5 = 398.71 ft
Answer:
Step-by-step explanation:
Do you mean 3/7x or 3/(7x) ?
If 3/7x = 33 then x = 33·7/3 = 77
If 3/(7x) = 33 then x = 1/77
