Kendra finds the dimensions of a sticky note. She uses a meter stick to determine that the dimensions are 1.25×10−8 meters wide by 2.5×10−6 meters long. Use scientific notation to write the dimensions in millimeters.
1. 1.25 x 10^-5 by 2.5 x 10^-3
2. 3.99 x 10^5
3. 6.02 x 10^25
4. 3.28 x 10^12
5. 2.81 x 10^
The Bot helped but you have to look hard through everything so I thought this would help. :)
To express the number 2.81E4 in scientific notation, we can write it as 2.81 x 10^4.
All those are correct
Thank you so much!!
I dont like cheating but i have other things i need to be focused on so this really helps
To convert meters to millimeters, we need to multiply by 1000 since there are 1000 millimeters in a meter.
The width is 1.25 x 10^(-8) meters, so in millimeters it is 1.25 x 10^(-8) x 1000 = 1.25 x 10^(-5) millimeters.
The length is 2.5 x 10^(-6) meters, so in millimeters it is 2.5 x 10^(-6) x 1000 = 2.5 x 10^(-3) millimeters.
Therefore, the dimensions in millimeters are 1.25 x 10^(-5) millimeters wide by 2.5 x 10^(-3) millimeters long.
To find the total number of seconds the playlist will play, we need to multiply the number of songs by the average time of each song in minutes and then convert it to seconds.
The number of songs is 1,900.
The average time of each song is 3.5 minutes.
To convert minutes to seconds, we multiply by 60 since there are 60 seconds in a minute.
The total number of seconds the playlist will play is 1,900 x 3.5 x 60 = 399,000 seconds.
Expressing this answer in scientific notation, we have 3.99 x 10^5 seconds.
To express the number of molecules in 100 moles in scientific notation, we can write it as 6.02 x 10^25.
To express the number 3.28E12 in scientific notation, we can write it as 3.28 x 10^12.

Jim’s music library on his phone holds 1,900 songs. The songs have an average time of 3.5 minutes. Use scientific notation to find the total number of seconds the playlist will play. Express the answer to the exact decimal place.
The number of molecules is given as 6.02E25, which is already in scientific notation.
Therefore, the number of molecules in 100 moles is 6.02E25.
The number displayed on the calculator, 3.28E12, is already in scientific notation.
Therefore, the amount of debt of the federal government after a third was paid in 1995 is 3.28E12.
The number displayed on the calculator, 2.81E4, is already in scientific notation.
Therefore, the half-life of Uranium-238 is 2.81E4 times greater than the half-life of Uranium-233.
