True. You just distribute the 2a to get 6a squared plus 8a
Esitmate:
9 /3 = 3
and
8-4 = 4
so it would be 3x10^4
answer is C
Answer:
$150
Step-by-step explanation:
Convert the percentage to decimal
50% = 0.5
Then Multiply the decimal to the number you need to find the percentage of
300 x 0.5 = 150
Hope this helps!
The answer would be 100 feet.
Using a grid, I found the answer. The problem said that each unit is 5 feet, right? This would mean that each square would be 5 feet. Counting by 5's means that you'll find the answer by each square. Just count the distance and multiply by 5. You'll get it, trust me.
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
