Answer: Hello this is my first time answering!  

DA= 4.5

CB=4.5

XY=9

If YZ=8 then CD=4

Perimeter of trapezoid ABCD=19

Perimeter of trapezoid WXYZ=38

Step-by-step explanation:

I am almost positive the scale is 0.5/1 this means that for DA it would be 4.5.  Of course, if DA was 4.5 then so would CB.  Everything is half of the second trapezoid.  

Thanks!

Answer:

a) The smallest possible number of sides of the polygon is a regular polygon with 5 sides

b) The largest possible number of sides of the polygon is a regular polygon with 9 sides

Step-by-step explanation:

a) The smallest exterior angle of the polygon = 40°

The largest exterior angle of the polygon = 80°

Therefore, we have the interior angles are;

The smallest interior angle of the polygon = 180° - 40° = 140°

The largest interior angle of the polygon = 180° - 80° = 100°

Therefore, we have

The interior angles of a regular polygon are given by the following formula;

[tex]Interior \ angle =\dfrac{(n-2) \times 180 ^{\circ}}{n}[/tex]

For an interior angle of 100°, we have;

[tex]100^{\circ} =\dfrac{(n-2) \times 180 ^{\circ}}{n}[/tex]

100/180 × n = n - 2

2 = n - 100/180 × n = 4/9·n

2 = 4/9·n

n = 18/4 = 4.5

Therefore, given that a square has an interior angle of 90° we have the smallest possible number of sides polygon = 5 sides

b) For 140°, we have;

[tex]140^{\circ} =\dfrac{(n-2) \times 180 ^{\circ}}{n}[/tex]

140/180 × n = n - 2

2 = n - 140/180 × n = 2/9·n

2 = 2/9·n

n = 18/2 = 9

n = 9 sides

Therefore, the largest possible number of sides = 9 Sides.

Answer:

One basic property of a parallelogram is that opposite angles have the same value. Hence angle B = angle D. (2n+15°) = (3n-5°). Then have one side for the unknown. The equation will be 3n=2n+15°+5°. To get the n, simplify the equation: 3n-2n = 20° or n = 20°. Afterwards substitute the value of n to the angles. Angle B = (2(20)+15), Angle D = (3(20)-5). Lastly, simplify the equations. Angle B = (40+15°) = 55° and Angle D = (60-5°)=55°. Therefore the value of angles B & D are both 55°.

Step-by-step explanation:

Since there are 10 total slices and 2 are red the probability of the dial stopping on a red slice is 2/10. But in simplest form 1/5.

The probability that the dial stops on a red slice is 1/5 or 20%.

The ratio of good outcomes to all possible outcomes of an event is known as the probability. The number of positive results for an experiment with 'n' outcomes can be represented by the symbol x. The probability of an occurrence may be calculated using the following formula.

Probability(Event) = Positive Results/Total Results = x/n

In order to better grasp probability, let's look at a straightforward example. Let's say we need to forecast if it will rain or not. Either "Yes" or "No" is the appropriate response to this query.

Given:

number of total slices = 10

Red slices = 2

Blue slices= 4

Yellow slices= 10- 6 = 4

Now, probability that the dial stops on a red slice

=2/10

=1/5

=1/5 x 100

=20%

Hence, the probability that the dial stops on a red slice is 1/5 or 20%..

Answer:

35

Step-by-step explanation:

*5.5w - 3.25 = 35.25

The 5.5w part shows that its $5.50 times each window. The -3.25 is because he deducted 3.25 from the total. And then you have the price that he got on the other side. 

Here's the work to find the windows in case you want it:

5.5w-3.25=35.25

5.5w=38.50

w=7

Answer:

100

Step-by-step explanation:

12x - 4 + 13x + 9 = 180

25x + 5 = 180

25x = 175

x = 7

13(7) + 9 = 100

Answer:

35 + 37

Step-by-step explanation:

if you try any other number like: 37 + 39 = 76 that doesn't work well because its higher that 75.

Area = (x - 5)(x – 7)

Area = x(x - 7) - 5(x - 7)

Area = x^2 -7x -5x + 35

Area = x^2 -12x + 35

algebraic expression that represents its area: x^2 -12x + 35

x^2 - 12x + 35 = 195

x^2 - 12x + 35 - 195 = 0

x^2 - 12x - 160 = 0

x^2 - 8x - 20x - 160 = 0

x (x + 8) - 20 (x + 8) = 0

(x + 8) (x - 20) = 0

(x + 8) = 0

(x - 20) = 0

x = - 8 (not a solution)

x = 20

hence,

length = x - 5

length = 20 - 5

length = 15 m

width = x - 7

width = 20 - 7

width = 13 m

perimeter = 2(13) + 2(15)

perimeter = 26 + 30

perimeter = 56 m²

The perimeter of the terrain is 56 m²

The area of Rectangle is length times of width.

Given,

The sides of a rectangular terrain are given by the expressions (x - 5) and

(x – 7) meters.

Given area of rectangle is  195 m²

Area of rectangle= (x - 5)  (x - 7)

195=x(x-7)-5(x-7)

195=x²-7x-5x+35

195=x²-12x+35

x²-12x+35-195=0

x²-12x-160=0

x²-8x-20x-160 = 0

x (x+8)-20(x+8)=0

(x-20)(x+8)=0

x=20 and x=-8

Length x-5=20-5=15

x-7=20-7=13

So length is 15m and width is 13m

the perimeter of the terrain =2(Length + width)

=2(15+13)

=2(28)

=56 m²

Hence the perimeter of the terrain is 56 m²

Step-by-step explanation:

The formula for calculating the area of a square is expressed as;

A = x² where;

x is the length of one side of the square

Given

x = 10in

A = 10²

A = 10 * 10

A = 100in²

Area of the square with side length 10in is 100in²

From the equation A = x², we can see that as the value of x increases, the value of the area also increases and vice versa. This means that the area of the square is directky proportional to its length. Hence we can say YES, the area of a square and the length of its side directly proportional
