Answer: B, D, E
Step-by-step explanation:
Hmm, we will do ratio and assume caputred is in proprtion
so
all:tagged=all:41
we will assume this is the same as
57:tagged in the 57
57-41=16 so 16 are not tagged
so
all/41=57/16
times both sides by 41
all=2337/16
all=146.something
about 146 storks
First....6÷1/2= 12
so.....12*3.9=46.8 milligram
(x-y)^2 +4xy = (x+y)^2
FOIL
x^2 -2xy+y^2 +4xy = (x+y)^2 x^2 -2xy
Combine like terms
x^2 +2xy +y^2 = (x+y)^2 x^2 +2xy
Factor
(x+y)^2 = (x+y)^2 (x+y)^2
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
