What is the area, in square feet, of the trapezoid below?
slavikrds [6]

Answer:

68.75

Step-by-step explanation:

Measure the length of the parallel sides and add them together. Then multiply this number by the height of the area. Then multiply by ½ or divide by two to find the square footage of the trapezoid.  

13.6 + 5.9= 19.5

19.5 + 8 = 27.5

27.5 x 5 = 137.5

137.5 x 1/2 = 68.75

Find the coordinates of the midpoint of a line segment with the given endpoints (14,-8), (12,-1)
Flauer [41]

Answer:

The coordinates of the midpoint of a line segment with the given endpoints (14,-8), (12,-1) are \mathbf{(13,\frac{-9}{2})}

Step-by-step explanation:

We need to find the coordinates of the midpoint of a line segment with the given endpoints (14,-8), (12,-1)

The midpoint of line segment can be found using formula:

Midpoint=(\frac{x_1+x_2}{2},\frac{y_1+y_2}{2})

We have x_1=14, y_1=-8, x_2=12, y_2=-1

Putting values and finding midpoint

Midpoint=(\frac{x_1+x_2}{2},\frac{y_1+y_2}{2})\\Midpoint=(\frac{14+12}{2},\frac{-8-1}{2})\\Midpoint=(\frac{26}{2},\frac{-9}{2})\\Midpoint=(13,\frac{-9}{2})

So, the coordinates of the midpoint of a line segment with the given endpoints (14,-8), (12,-1) are \mathbf{(13,\frac{-9}{2})}

PSYCHO15rus [73]

Step-by-step explanation:

81 - 1.2x < 55

81 < 55 + 1.2x (add 1.2x to both sides)

1.2x > 26 (subtract 55 from both sides)

x > 21 2/3.
