Write 0.002349 in scientific notation.

Studentka2010 [4]

Hi! I'm happy to help!

To solve this, we first need to know what scientific notation is. Scientific notation is a way a number is written. You write it using a number ranging from 1 to <10. Then, you multiply this number by $10^{x}$ .

In order to make this number reasonable for scientific notation, you have to move the decimal a certain amount of places. In this case you move it 3 places to the right to make your number 2.349. Since we moved it 3 places to the right our x will be -3. (If we'd moved it 3 places to the left, our x would be positive 3.)

So now, we insert our numbers:

2.349· $10^{-3}$

You write 0.002349 like 2.349· $10^{-3}$ , when it is in scientific notation.

I hope this was helpful, keep learning! :D

Ravi has some money. If he buys 40 doughnuts, he will have $5 left. If he buys 50 doughnuts,he will need another $15. How much d

anastassius [24]

Difference in doughnuts = 50 - 40 = 10
Difference in money = 15 + 5 = 20

20 ÷ 10 = $2
Each doughnut costs $2

Check:
40 x 2 + 5 = $85
50 x 2 -15 = $85
Ravi has $85 at first.

Each doughnut costs $2
