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:
949
Step-by-step explanation:
If the 3 digit number is rounded to 900, then this number is between 900 and 950.
The digit in the ones place is the fifth odd number begginning with 1, so this number is number 9.
Lastly, the sum of digits is 22.
Putting our number as 9x9, where x is the tens digit, we know that 9 + x + 9 = 22, so we have that x = 4
So, our number is 949
