If it takes 21 minutes for 5 people to paint 7 walls how many minutes does it take 3 people to paint 5 walls

RideAnS [48]

Answer:

21 minutes divided by 7 walls = 3 minutes per wall for 5 people.

Assuming each worker has the same exact productivity, one person would take 15 minutes to paint a single wall (3 minutes x 5 people to get the amount of time for 1 worker per wall).

15 minutes for one worker multiplied by 5 walls = 75 minutes for one worker. Divide 75 minutes by 3 people = 25 minutes to paint all 5 walls with 3 people.

Margaret [11]

distance of Vondra & Mei is 6 meters.

<u>Step-by-step explanation:</u>

Here we have , Three baseball players are playing catch. Vondra is directly south of Mei and directly west of Yoshi. Vondra and Yoshi are 8 meters apart and Yoshi and Mei are 10 meters apart. Let's analyze step by step:

Vondra is directly south of Mei : Vondra & Mei , are south to each other.

Vondra is directly west of Yoshi: Vondra & Yoshi , are west to each other.

Distance of Vondra & Mei = x = Perpendicular

Distance of Yoshi and Mei = 10 m = Hypotenuse

Distance of Vondra and Yoshi = 8 m = base

In order , to find distance of Vondra & Mei we use Pythagoras Theorem:

$10^{2} = x^{2} + 8^{2} \\10^{2} - 8^{2} = x^{2}\\100 - 64 = x^{2}\\x^{2} = 36\\x = 6m$ , ∴ distance of Vondra & Mei is 6 meters.
