25. Find the area of the trapezoid. Leave your answer in simplest radical form. The figure is not drawn to scale.

n200080 [17]

Answer:

Option D. $44\ cm^{2}$

Step-by-step explanation:

we know that

The area of a trapezoid is equal to

$A=\frac{1}{2}[b1+b2]h$

we have

$b1=8\ cm$

$b2=(4+8+2)=14\ cm$

$h=4\ cm$

substitute the values

$A=\frac{1}{2}[8+14](4)=44\ cm^{2}$

Answer:

Since you didn't mention which question.

Step-by-step explanation:

13.

$1.\overline{52}\\$ = 1.525252...

Let x = 1.525252...

10x = 15.2525252....

100x = 152.525252...

100x - x = 151.00

99x = 151

$x = \frac{151}{99}\\\\or\\\\x = 1 \frac{52}{99}$

14.

4x + 10 = 8x - 26 [ corresponding angles are congruent ]

4x - 8x = - 26 - 10

- 4x = - 36

$x = \frac{-36}{-4} \\\\x = 9$

15.

Given breadth of a rectangle is ( 2/3) its length.

Let the length be x

Therefore, breadth = ( 2 /3) of x

$= \frac{2}{3} \times x\\\\=\frac{2}{3}x$

Given perimeter = 40m

Perimeter of a rectangle = 2( length + breadth)

$40 = 2 (x + \frac{2}{3}x )\\\\\frac{40}{2} = \frac{2}{2}(x + \frac{2}{3}x)\\\\20 = x + \frac{2}{3}x\\\\20 = \frac{3x + 2x}{3}\\\\20 \times 3 = 5x \\\\x = \frac{60}{5}\\\\x = 12\\\\Therefore, Length = x = 12 \ m \ and \ breadth = \frac{2}{3}x = \frac{2}{3} \times 12 = 8 \ m$

16.

Sum of the angles of a triangle = 180°

Given ratio = 2 : 3 : 4

Sum of the ratio = 9

Therefore,

$first \ angle = \frac{2}{9} \times 180 = 2 \times 20 = 40 ^\circ\\\\Second \ angle = \frac{3}{9} \times 180 = 3 \times 20 = 60^\circ\\\\Third angle = \frac{4}{9} \times 180 = 4 \times 20 = 80^\circ$

17.

Sum of interior angles of a polygon with n sides = ( n - 2) x 180°

Given polygon is pentagon, that is n = 5

Therefore, sum of the interior angles = ( 5 - 2) x 180 = 3 x 180 = 540°

That is ,

x + 125 + 125 + 88 + 60 = 540°

x + 398 = 540°

x = 540 - 398

x = 142°

Randy's circular garden has a radius of 1.5 feet.He wants to enclose the garden with edging that costs $0.75 per foot. About how

Vesna [10]

Answer:Circumference = 2 \pi r

circumference = 2 \pi (1.5)

circumference = 9.42 feet

The circumference is 9.42 feet, so we need to get fencing for 10 feet (assuming the fence comes in feet, i.e. you cant buy half a foot)

1 feet = $.075

10 feet = $0.75 x 10 = $7.50
