Can someone explain how the answer to #14 is 7/8 in;0.875 in.

Tamiku [17]

Of the 16 small intervals indicated from 0 to 1 inch, the ant spans 14 of them, so

$\dfrac{14}{16} = \dfrac{7}{8} \textrm{ inches} = 0.875 \textrm{ in}$

How is 7/8 equal to 0.875?

Since 125(8)=1000 and 125(7)=875 we know

$\dfrac{7}{8} = \dfrac{7 \cdot 125}{8 \cdot 125} = \dfrac{875}{1000} = 0.875$

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,

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