Answer:

The Susana swam the fastest.

Step-by-step explanation:

<u>Speed</u> : It is defined as the distance traveled per unit time.

<u>Formula used</u> : Speed = \frac{Distance}{Time}

First we have to determine speed of the following persons.

<u>For Tawni :</u>

Distance = 50 m

Time = 40.8 s

1.225 m/s which is the speed of Tawni.

--

<u>For Pepita :</u>

Distance = 100 m

Time = 60.2 s

1.661 m/s which is the speed of Pepita

--

<u>For Susana :</u>

Distance = 200 m

Time = 112.4 s

1.779 m/s which is the speed of Susana

From this we conclude that, in this problem meter affects the response and the speed of Susana is more than the Pepita and Tawani.

Thus, Susana swam the fastest.

5x + 4 = 7x i need help quick
anyanavicka [17]
5x + 4 = 7x

Subtract 4 from both sides.

5x = 7x - 4

Subtract 7x from both sides.

5x - 7x = -4

Simplify.

-2x = -4

Divide both sides by -2.

x = 4/2

x = 2

A regular decagon has a radius of 8 cm. what is the approximate area of the decagon? recall that a decagon is a polygon with 10
lianna [129]

The approximate area of the decagon with a side of 8cm comes to be 492.40 cm².

The side of the regular decagon = 8cm

<h3>What is a regular decagon?</h3>

A regular decagon is a polygon with 10 sides that are equal to each other.

The area of a regular decagon with side a is:

A=\frac{5}{2} a^{2} \sqrt{5+2\sqrt{5} }

So, the area A of the regular decagon with a side of 8cm:

A=\frac{5}{2} 8^{2} \sqrt{5+2\sqrt{5} }

A=160\sqrt{5+2\sqrt{5} }

A=492.40 cm²

Therefore, the approximate area of the decagon is 492.40 cm².
