3.82e+7 in standard form shown in calculator display

Answers

The answer is 3.82*10^7.

This is because in the calculator when the number is quite big enough or small enough it is written in a standard form which is 3.82*e^7 as the calculator is not able to write in the power of 10.

So whenever it is e to the power something it means it is 10 to the power something. In this case it was 3.82*e^7 which means 3.82*10^7. Which means 38200000.

e+7 means 10^+7
basically move the decimal place 7 placs to right so it would be aprox
38200000.0

There are two connected gears. One has 60 teeth and it makes 50 complete revolutions in a minute. How many complete revolutions will the second gear complete, if it has 40 teeth?

Answers

60 teeth = 50 revolutions

40 teeth = x revolutions

To figure this out, you can multiply 60 and 50 together to get 3000, and 40 and x to get 40x.

If you solve this equation, 40x = 3000,

x = 75

Hope this helped!

The Second gear will complete 75 revolutions.

Hope this helps. I tried using my past knowledge.
