If the areas of two similar decagons are 625 ft^2 and 100 ft^2, what is the ratio of the perimeters of the decagons? tf is a dec

const2013 [10]

$\text{Answer: }\frac{\text{ Perimeter of first decagon}}{\text{ Perimeter of second decagon}}=\frac{5}{2}$

Step-by-step explanation:

Since we have given that

Area of two similar decagons are 625 ft² and 100 ft² ,

As we know the relation of area of similar figures, i.e.

$\frac{\text{ Area of first decagon}}{\text{ area of second decagon}}=\frac{625}{100}=\frac{a^2}{b^2}$

Now, we also know that ,

$\frac{\text{ Perimeter of first decagon}}{\text{ Perimeter of second decagon}}=\frac{a}{b}=\frac{\sqrt{625}}{\sqrt{100}}=\frac{25}{10}=\frac{5}{2}$

Hence,

$\frac{\text{ Perimeter of first decagon}}{\text{ Perimeter of second decagon}}=\frac{5}{2}$

Which formula can be used to describe the sequence below? <br> 29, 9, 3, 1, 1/3,.....

Maksim231197 [3]

Answer:

Answer is $3^{4-n}$

Step-by-step explanation:

It is 29 in place of 27 . and Its a geometric series with first term 27 and common ratio $\frac{1}{3}$

and general formula for given sequence is given by $a (r)^{n-1}$

so plugging the value of a and r ,we get

$27 ([tex]\frac{1}{3}$ )^{n-1}[/tex]

$3^3(\frac{1}{3} )}^{n-1}$

$3^{4-n}$
