Which pairs of rectangles are similar polygons? Select each correct answer.

The corrects answers are B and D for this one. 

Since you divide the same side for both the the rectangles on both parts and if the division statements are equaled, then they are similar. 

For example; 

Answer B. 
50 / 10 = 5 
and 
30 / 6 = 5 

Answer D. 
7.5 / 2.5 = 3
and 
4.5 / 1.5 = 3 

Since they both equal the same for both of the rectangles for the answers individually, they are similar polygon rectangles. 

Hope this helps!

Answer: Second and fourth pairs of rectangle are similar.

Explanation: Since, If two Shapes are similar then the ratios of their corresponding sides are equal.

In First figure ratios of corresponding sides are not equal.

Because, \frac{100}{10}≠ \frac{10}{7}

Therefore, they are not similar.

In second figure ratios of corresponding sides are equal.

Because, \frac{50}{10}= \frac{30}{6}=5

Therefore, they are similar.

In third figure ratios of corresponding sides are not equal.

Because, \frac{5.2}{2.6}≠ \frac{3.8}{1.2}

Therefore, they are not similar.

In fourth figure ratios of corresponding sides are equal.

Because, \frac{7.5}{2.5}=\frac{4.5}{1.5}=3

Therefore, they are similar.

Aline crosses the coordinates (-4,4) and (2.-5). What is the slope<br> of the line?
lisabon 2012 [21]

Answer:

Step-by-step explanation:

Use the slope formula:

m = \frac{y2 -y1}{x2 - x1}

where m = slope

Given the coordinates

(-4, 4) ---> this means x1 = -4 , y1 = 4

(2, -5) ---> this means x2 = 2 , y2 = -5

Substitute these values into the slope formula:

m = \frac{y2 -y1}{x2 - x1}

m = \frac{-5 -4}{2 - (-4)}  = \frac{-9}{2+4} = \frac{-9}{6} = \frac{-3}{2}

Answer:

Step-by-step explanation:

1. a). Hypotenuse² = (Leg 1)² + (Leg 2)²

       h² = 10² + 24²

       h = √676

       h = 26

 (b). Hypotenuse² = (Leg 1)² + (Leg 2)²

       (25)² = (15)² + (leg 2)²

       Leg 2 = √(625 - 225)

                 = √400

                 = 20

  (c). Hypotenuse² = (Leg 1)² + (Leg 2)²

        h² = 4² + 6²

        h = √(16 + 36)

        h = √52

        h = 2√13

  (d). Hypotenuse² = (Leg 1)² + (Leg 2)²

        (14)² = (Leg 1)² + 7²

         Leg 1 = √(196 - 49)

                   = √147

                   = 7√3

2). Hypotenuse² = (Leg 1)² + (Leg 2)²

    Leg 1 = leg 2 = 7 units [Since, triangle is an isosceles triangle]

    h² = 7² + 7²

    h = √98

    h = 7√2

    Option (1) is the correct option.

3). Hypotenuse² = (Leg 1)² + (Leg 2)²

    (26)² = (Leg 1)² + (10)²

    Leg 1 = √(676 - 100) = 24

    Area of a right triangle = \frac{1}{2}(\text{Leg 1})(\text{Leg 2})

                                           = \frac{1}{2}(24)(10)

                                           = 120 square units

     Option (3) is the correct option.
