Let's say you have two similar polygons and the ratio of their perimeters is 6:1. What is the ratio of corresponding sides?

1 answer:

7 0

Well if we had a four sided polygon with the sides of x1, x2, x3, x4. Where the perimeter is: (x1 + x2 + x3 + x4), A similar polygon will have proportional sides. Their sides would be > kx1, kx2, kx3, kx4.....sooo... The perimeter is: (kx1 + kx2 + kx3 + kx4) > k(x1 + x2 + x3 + x4) therefore the ratio is the same because the perimeter and sides are the same. So 6:1

Hope this helps!

If a sphere has a volume of 9198.1 in, what is the radius of the sphere?

KonstantinChe [14]

Answer:

Step-by-step explanation:

Volume to find radius: $(3\frac{V}{4\pi})^1^/^3$

Substitute: $(3\frac{9198.1}{4\pi})^1^/^3$

Solve: $(3(732.3))^1^/^3$

$2196.9^1^/^3$

How many solutions does this equation have?

fenix001 [56]

Answer: exactly one solution

Explanation: first we have to solve it. so in 2 + 6x = 3x + 3 we have to subtract 2 from both sides and we get 6x = 3x + 1. then, we subtract 3x from both sides and we get 3x = 1. we divide both sides by 3 and get x = 1/3, which is the only solution.

What is the value of x

VashaNatasha [74]

Answer:

x = 40

Step-by-step explanation:

According to the Supplementary Angles Theorem, set 4x - 20 and x equal to 180. Once done, combine like-terms to get 5x - 20 = 180. So, straight off the bat, we know that 5x has to equal 200 [bringing 20 over to the right side of the equivalence symbol], therefore 40 is equal to x.

Mrs. Nevin is making a costume for a school play. She needs a piece of fabric that is greater than 1/2 of a yard but less than 5

Bumek [7]

Answer:

4/7 yards

Step-by-step explanation:

Given that :

Required fabric is > 1/2 but < 5/8

Let required fabric = x

Then ;

Converting the fractions to decimal :

1/2 = 0.5 ; 5/8 = 0.625

0.5 < x < 0.625

3/8 yards = 0.375 ;

4/7 yards = 0.571

3/7 yards = 0.429

2/4 yards = 0.5

0.5 < 0.571 < 0.625

From the options, only 4/7 yards satisfies the condition :
