Answer:
its B... i think(sub2pewdiepie)
Step-by-step explanation:angle 4 is 100 degrees and 4 and 8 are corresponding
Let x be the shorter side, and y be the longer side
There would be 4 fences along the shorter side, and 2 fences along the longer side
4x + 2y = 800
Rewrite in terms of y:
y = 400 − 2x
The area of the rectangular field is
A = x*y
Replace Y with the equation above:
A = x(400 − 2x)
A = − 2x^2 + 400x
The area is a parabola that opens downward, the maximum area would occur at the parabola vertex.
At the vertex
x = −b/2a
= −400/[2(−2)]
= 100
y = 400 −2x
y = 400 -2(100)
y = 400-200
y = 200
The dimension of the rectangular field that maximize the enclosed area is 100 ft x 200 ft.
This is a conversion problem..
<span>1 cm = 0.01 m

so 150 cm would be 1,50
So it's D.<span>1.50 m</span>³
2/5 in decimal form would be 0.4
