Can someone my sister with #3 and #4 . i tried and i can’t figure it out.

#3 Which of the following is less than 527 m?

A. 0.000699 Mm = 0.000699 · 1,000,000 m = 699 m  

B. 914,879,710 nm = (914,879,710 : 1,000,000,000) m = 0.914879710 m  

C. 51,723 cm = (51,723 : 100) m = 517.23 m  

The best answer is C

#4 How many songs would you have if the average file size is 4,000 kb?

8 gb: 1,700 songs

16 gb: 6,000 songs

2 gb: 500 songs

160 gb: 30,000 songs

64 gb: 14,000 songs

1 Terabyte = 1024 gb: so im guessing 350,000 songs

This depends on the length of the song and the file format/type. A typical mp3 song of around 4 minutes averages 4 MB (4000 KB).

let's solve your equation step-by-step.

4x+2=2x+12

step 1: subtract 2x from both sides.

4x+2−2x=2x+12−2x

2x+2=12

step 2: subtract 2 from both sides.

2x+2−2=12−2

2x=10

step 3: divide both sides by 2.

2x

2

=

10

x=5

step-by-step explanation:

6,250

step-by-step explanation:

to get the area, multiply 360 by 160.(57,600)

to find out how many bags of fertilizer it will take, first figure out how many square feet one bag can hold. divide 1000 by 8(125) to get the unit rate(how many square feet one pound of fertilizer can hold)and multiply it by 50(6250). if i haven't made a mistake, that is the answer.
