Answer:

6 feet

Step-by-step explanation:

Let the length of side length in polygon A be represented by x. Since the two polygons are similar, then it can be deduced that;

Area scale factor = [tex](linear scale factor)^{2}[/tex]

linear scale factor = [tex]\sqrt{Area scale factor}[/tex]

Area scale factor = [tex]\frac{98}{18}[/tex]

So that,

linear scale factor = [tex]\sqrt{\frac{98}{18} }[/tex]

                              = 2.3333

The length of side of polygon A = [tex]\frac{14}{2.3333}[/tex]

                                       = 6.0085

Therefore, the corresponding side length of polygon A is 6 feet.

Answer:

3/29

Step-by-step explanation:

area of total rectangle is 12x8 or 96 sq cm

area of shaded square is 9

96 - 9 = 87 sq cm, which is area of unshaded region

9 out of 87 is the probability of selecting a point in the shaded region, which simplifies to 3/29

Answer:

lol i see r o b l o x

Step-by-step explanation:

Rectangle = bxh

thats is 96

the we know that the square in the middle is 3x3x3x3 or 81

then subtract the two which is 15

Answer:

(x1,y1)   is  (2,7)

    (x2,y2)   is  (0,1)

Step-by-step explanation:

Point-slope form is:

  (y-y1) = ( (y2-y1) / (x2-x1) )(x - x1)

   y - 7 =( (-6)/(0-2) )(x-2)

   y - 7 = 3x - 6

    y = 3x + 1    [slope-intercept form]

Check:

  Is  (2,7) on the line:

       7 = 3(2) + 1   ?

       y = 7   ?yes

  Is (0,1) on the line:

       1 = 3(0) + 1   ?

       1 = 1   ? yes

Answer:

y=3x+1

to find the slope, find the change in y/change in x

7-1=6

2-0=2

6/2=3

3 is your slope

your y intercept occurs when x=0, and that was given to you in the problem

(0,1)

your y int is 1

y=3x+1

Step-by-step explanation:

The design that every point on one side of the line coincides with a point on the other side of it is Line of symmetry

Symmetry in mathematics means that when one shape is moved, rotated, or flipped, it looks exactly like the other shape.

A circle or band that divides a body's surface into two typically equal and symmetrical portions.

When a shape or item has a central point, point symmetry occurs when all points on the opposing sides are at the same distance from the centre.

The term "line of symmetry" refers to the fictitious axis or line that can be used to fold a figure into symmetrical halves.

It denotes that one half is the other half's mirror image.

Thus, the required design is Line of Symmetry.

Step-by-step explanation:

Answer:

50mb

Step-by-step explanation:

So start with what you have 300/150 = 2 so each song took up 2mb of space, so 25 songs would take up 25x2= 50mb

The number of megabytes taken up by 25 songs is 50 megabytes.

It is the quantity of an amount of something at a rate of one of another quantity.

In 2 hours, a man can walk for 6 miles

In 1 hour, a man will walk for 3 miles.

We have,

150 songs = 300 megabytes

1 song = 300 /150 megabytes

1 song = 2 megabytes ______(1)

Now,

Multiply 25 on both sides of (1).

25 songs = 25 x 2 megabytes

25 songs = 50 megabytes

Thus,

25 songs will take 50 megabytes.
