10m3 of air weigh 13 kg. make a chart showing weight of 15m3 of air, 30m3 of air, 40m3 of air

am giving 50 points and.. will mark brainliest pls tell me now!

Volume: 15        30       40

Weight: 19.5      39       52

Step-by-step explanation:

I did since  10m^3=13, 13/2=6.5 5m=6.5

6.5*3=19.5

6.5*6=39

6.5*8=52

Hope This Helped

Volume                                     Factor                                Mass

10 m³                                            1                          13 kg

15 m³ (=1.5 x 10 m³)                     1.5                       1.5 x 13 kg = 19.5 kg

30 m³ (=3 x 10 m³)                       3                         3 x 13 kg = 39 kg

40 m³ (=4 x 10 m³)                       4                        4 x 13 kg = 52 kg

the camry sales+accord sale=828,000. to make it so the two numbers are 18 thousand apart and still equal 828,000, you first need to find out what half of 828,000 is. 828,000/2=414,000. for the two numbers to equal 828,000, you have to add the same amount as you subtract from the middle. in this case, the number is 9,000 because it's half of 18,000. to equal 828,000, you have to add 9,000 to 414,000 for the camry and subtract 9,000 from 414,000 for the accord. 414,000+9,000=423,000.

414,000-9,000=405,000.

423,000+405,000=828,000.

423,000-405,000=18,

hope it
