The areas of two similar polygons are in the ratio 64:81. find the ratio of the corresponding sides.

Answers

Answer 1

Answer:

If the areas of two similar polygons are in the ration 64:81, then the ratio of their corresponding sides are $(8)/(9)$

What are polygons?

"A polygon, in geometry, any closed curve consisting of a set of line segments (sides) connected such that no two segments cross."

The simple polygons are triangles (3 sides), quadrilaterals (4 sides), and pentagons (5 sides).

Now if we take the given polygon as square (4 sides).

Then,

Let the sides of squares are a and b.

$(a^(2) )/(b^(2) )=(64)/(81) \n(a)/(b)=\sqrt{(64)/(81) } \n(a)/(b)=(8)/(9)$

Hence, the ratio of the corresponding sides of polygon is $(8)/(9)$

Answer 2

Answer: Answer is 8:9. The easiest example is a square. If the polygons are squares with areas of 64 and 81 then the sides of the squares are 8 and 9. Therefore, the ratio of the corresponding sides is 8:9

What is the solution to 2x+12=5x-9

Answers

so 2x+12=5x-9
you want all of the unknowns on one side and all of the known values on the other or
subtract 2x from both sides
12=3x-9
add 9 to both sides
21=3x
divide both sides by 3
7=x

$2x+12=5x-9\ \ \ \ |combine\ like\ terms\n\n2x-5x=-9-12\ \ \ \ \ |simplify\n\n-3x=-21\ \ \ \ \ |:-3\n\nx=7$

Answer:

88%

Step-by-step explanation:

22/25 = .88 x 100= 88%

Answer:

88%

Step-by-step explanation:

First, you start with the bottom (denominator). You turn it into 100 since all percentages are over 100. So 25 times 4 is 100. Therefore, you also have to multiply the top with a 4, getting an 88 over 100. That is equal to 88%.

A circle has a diameter with endpoints of (2, -8) and (6, 4). What is the center of the circle?

Answers

The length of the diameter is (4,12)
The center is (4, -2)

Diameter = √(y2-y1)² + (x2 - x1)²
d = √(4-(-8))² + (6-2)²
d = √12² + 4²
d = √144 + 16
d = √160

In short, Your Answer would be √160 or 12.65
