I'm so confused. Please help I tried the first time got 50 some thing then 33 then 20.25. How do I do this?
vazorg [7]

Answer:

Basically, you have to think: more bricks : more time

more workers : less time

2,400 bricks 6 workers takes 18 hours

You now have to solve for 4,500 blocks and 10 workers

4,500 / 2,400 = 1.875 (times greater)

10 / 6 = 1.666666666 (times less)

So, we get 18 hours, multiply it by 1.875 and divide it by 1.666666666

which equals 20.25 hours

So, it seems you were correct on your third try.

When a plane flies into the wind, it can travel 3000 ml in 6 h . When it flies with the wind, it can travel the same distance in
jeka94

Answer:

  • plane: 550 mph
  • wind: 50 mph

Step-by-step explanation:

If p and w represent the speeds of the plane and wind, respectively, the speed into the wind is ...

  p - w = (3000 mi)/(6 h) = 500 mi/h

And, the speed with the wind is ...

  p + w = (3000 mi)/(5 h) = 600 mi/h

Adding these two equations gives us ...

  2p = 1100 mi/h

  p = 550 mi/h . . . . . . . divide by 2

Then the wind speed is ...

  w = 600 mi/h - p = (600 -550) mi/h

  w = 50 mi/h

The rate of the plane in still air is 550 mi/h; the rate of the wind is 50 mi/h.

An item that originally costs $320 is on sale for 22% off. What is the sale price? Show your work. PLZ SHOW UR WORK!
Mnenie [13.5K]

<u>Answer:</u>

The answer is $249.60

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

This is a simple question. Firstly you will take the total cost and multiply it by 0.22. The answer to this is 70.4. Take that and subtract it from the total cost because 70 is the discount price. Once subtracted you will get 249.6. In conclusion, the sale price of the item is $249.60.

P.S. I hope this answer helped you in some way or another. If you have any questions you can ask them to me and I will be happy to help you out. I also wanted to add that I have a channel called The Game Rater or soon to be Nitro Studios (based on when you see this). I would really appreciate it if you could check out my channel. If not, I hope this answer helped you and I still appreciate you reading this side note. Thank you.
