olga_2 [115]

Dana made 96 strides.

Step-by-step explanation:

Given,

Ratio of Sally's stride to Dana's strides = 5:4

Strides made by Sally = 120

Let,

x be the strides made by Dana.

Ratio of Sally to Dana = 120:x

Using proportion;

Ratio of Sally's stride to Dana's stride :: Ratio of Sally to Dana

$5:4::120:x$

Product of mean = Product of extreme

$4*120=5*x\\480=5x\\5x=480$

Dividing both sides by 5

$\frac{5x}{5}=\frac{480}{5}\\x=96$

Dana made 96 strides.

How to do you find the radius of a square with a circle inscribed into it?

Shkiper50 [21]

<span>When used in reference to a square, the radius is the distance from the center of the square to any of the four vertices, or where two sides intersect. Because a square has four right angles, you can find the diameter of the square using the Pythagorean Theorem. Multiply the side length of the square by itself.
