Answer:

A

Step-by-step explanation:

Because a centroid has a side on which x=2(y), if you had a picture i could better explain. Also I took the edge test.

A rectangular lawn, 100 feet long by 50 feet wide, is to have two sidewalks installed that will cut the lawn in half both ways,
Damm [24]

Answer:

3.41 feet

Step-by-step explanation:

Area = Length × Breath

Area of the rectangular lawn = 100 × 50

                                                = 5000 feet²

The sidewalk must occupy an area no more than 10% of the total lawn area.

So, the area of the sidewalk would be not more than  = 10% × 5000

                                                                                         = 0.10 × 5000

                                                                                        = 500 feet²

Let the width of the sidewalk = x feet

area of the side walk = (L×W of the long way) + ((L-x)×W of the short way)

(100 × x) + ((50 - x) × x) < 500

100x + (50-x)(x) < 500

-x²  + 150x < 500

-x² + 150x = 500

-x² + 150x - 500 = 0

By using quadratic formula

x=\frac{-b\pm\sqrt{b^2-4ac} }{2a}

x=\frac{(-150)\pm\sqrt{(150)^2-4(-1)(-500)} }{2(-1)}

x=\frac{-150\pm \sqrt{20500} }{-2}

x=75-5\sqrt{205} or x=75+5\sqrt{205}

x = 3.41089 ≈ 3.41 feet  or  x = 146.58

Therefore, width of the sidewalk would be 3.41 feet.

If P = (-2,-1) and Q = (4,3) are the
Ivanshal [37]

Answer:

Step-by-step explanation:

P(-2,-1) and Q(4,3)

average of x-coordinates = (-2+4)/2 = 1

average of y-coordinates = (-1+3)/2 = 1

midpoint of PQ: (1,1)

distance between midpoint and Q = √((4-1)²+(3-1)²) = √13

(x-1)² + (y-1)² = 13

Solve 6x - 3y = 12 for y<br> A. y = 6x + 4<br> B. y = 2x - 4<br> C. y = -6x + 12<br> D. y = 2x - 12
DedPeter [7]

Answer: <em>y = 2x − 4</em>

The correct answer is <em>B)</em> <em>y = 2x − 4</em>

Step-by-step explanation:

<u>Move all terms that don't contain y to the right side and solve:</u>

<em>y = −4 + 2x</em>

<u>Then reorder −4 and 2x:</u>

<em>y = 2x − 4</em>

<u>Final answer is:</u>

<em>B) y = 2x − 4</em>
