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
X would have to be the variable for 3
Answer:
x=36° (180/5x because 2x+3x)
Step-by-step explanation:
For the first one the answer is 15
43+82+63+87=275
Thursday
1 and a half
D
1452 feet squared
Replace x with 5 in each equation then subtract:
f(x) = 2(5)^2 - 4(5) = 30
g(x) = 5-2(5) = -5
f(x) - g(x) = 30 - - 5 = 30 +5 = 35
The answer is C. 35
