Answer:

1,000 feet

Step-by-step explanation:

From point Q to point R, the x values change by 20 units while the y values stay the same.  This side of the polygon has a length of 20

From point R to point S, the y values change by 30 units while the x values stay the same.  This side of the polygon has a length of 30

From point S to point T, the x values change by 20 units while the y values stay the same.  This side of the polygon has a length of 20

From point T to point Q, the y values change by 30 units while the x values stay the same.  This side of the polygon has a length of 30

The total perimeter is 20 + 30 + 20 + 30 = 100 units, each unit represents 10 feet, so the total perimeter is 100(10) = 1,000 feet

Answer:

100 feet

Step-by-step explanation:

side lengths:

y2-y1 = /-10-10/ = 20 units

x2-x1= /20-(-10)/ = 30 units

20+20+30+30 = 100

The midpoint of a line segment is (−1,6) . One endpoint of the line segment is (4,−7) .
pogonyaev

Answer:

The other coordinate is (-6,19)

Step-by-step explanation:

m = ( \frac{x1 + x2}{2} , \frac{y1 + y2}{2} )

(4,-7)

(x,y)

[(4+x)/2 , (-7+y)/2] = (-1,6)

(4 + x)/2 = -1

4 + x = -2

× = -6

(-7 + y)/2 = 6

-7 + y = 12

y = 19

What is the slope of the line that passes through the given points? (1 point)
frez [133]
(1/2,3)(2,3/4)
slope = (3/4 - 3) / (2 - 1/2) = (3/4 - 12/4) / (4/2 - 1/2) =
(-9/4) / (3/2) = -9/4 * 2/3 = -18/12 = -3/2

If I have line segmants with the measurements 3in, 5 in and 8 in; can I make a triangle?​
Dimas [21]

Answer:

Equilateral Triangle

Side a = 1

Side b = 1

Side c = 1

Angle ∠A = 60° = 1.0472 rad = π/3

Angle ∠B = 60° = 1.0472 rad = π/3

Angle ∠C = 60° = 1.0472 rad = π/3

C=60°B=60°A=60°b=1a=1c=1

Area = 0.43301

Perimeter p = 3

Semiperimeter s = 1.5

Height ha = 0.86603

Height hb = 0.86603

Height hc = 0.86603

Median ma = 0.86603

Median mb = 0.86603

Median mc = 0.86603

Inradius r = 0.28868

Circumradius R = 0.57735

Vertex coordinates: A[0, 0] B[1, 0] C[0.5, 0.86603]

Centroid: [0.5, 0.28868]

Inscribed Circle Center: [0.5, 0.28868]

Circumscribed Circle Center: [0.5, 0.28868]
