Remark

You cannot give an answer to this unless you are give the fastest speed of a swimmer. That stat is not an easy one to decide upon. At what distance for example or do you eliminate distance? Since this is a college level question, I don't think it unreasonable that you have to research raw distance over fastest time.

The fastest speed I can find is 100 meters in 46.91 seconds.  That means that the actual speed of the swimmer is 100 meters / 46.91 = 2.132 meters / second.

Givens

Set up a proportion with the numbers found and given

Speed of ball / speed of swimmer = 21.12 / 1

Speed of ball = x

Solution

Speed of swimmer = 2.132 m/s

x / 2.132 = 21.12 / 1          Multiply Both sides by 2.132

x = 21.12 * 2.132 / 1

x = 45.02 m/s

Answer

45.02 m/s

Answer:

42.66s = 21.12 * 2.02\\   = 42.66 m/s m/s

Step-by-step explanation:

The fastest swimmer, Caeleb Dressel holds the record of 49.50 for 100m

Taking the distance and time, we can compute the velocity:

V = \frac{displacemnent}{time} \\= \frac{100m}{49.50s}\\= 2.02 m/s

The velocity (speed) of the fastest swimmer will be 2.02 m/s

A tennis ball will travel at 21. 12 times faster which is:

Answer:

She shouldn't tip at all since that's a ridiculous concept

Step-by-step explanation:

common sense

SORRY MADE A MISTAKE WITH THE CALCULATOR I KNEW I MESSED SOMETHING UP

The cost of the meal was $22 so that's the price plus tax and tax is 10% of the price so

cost = price + 0.1*price

cost = 1.1 * price

price = cost / 1.1

price = 22 / 1.1 = <u>20</u>

now we need 20% of that so that's

20 * 0.2 = <u>4</u>

If she's simple-minded enough to tip that would amount to <u>$4</u>

Find the area of this figure (50 points)
Softa [21]

Answer:

A_{total} = 14\ in^2

Step-by-step explanation:

<u>Step 1:  Determine the area of the left rectangle</u>

We can tell that the total shape seems like two rectangles glued together.  We can separate the left rectangle and determine the area of it and then determine the area of the right rectangle and combine them.  Lets first solve the left rectangle.

A = l * w

A_{left\ rectangle} = 2\ in * 4\ in

A_{left\ rectangle}  = 8\ in^2

<u>Step 2:  Determine the area of the right rectangle</u>

A = l * w

A_{right\ rectangle} = 3\ in * 2\ in

A_{right\ rectangle} = 6\ in^2

<u>Step 3:  Determine the total area</u>

A_{total}=A_{left\ rectangle} + A_{right\ rectangle}

A_{total} =  8\ in^2 +  6\ in^2

A_{total} = 14\ in^2

Answer: A_{total} = 14\ in^2
