3/4 = 0.75
0.75 x 20 = 15
or
3/4 x 20/1 = 60/4 = 15
5 ÷ 3/4 = 5 x 4/3 = 20/3 = 62/3
4 x 20 = 80 4 x 19 = 76 Answer: 19 with 3 remaining
3/4s because a simpler way to say it is .34 with a line over the 3 and 4, and that as a percent is 75% and 75% as a fraction would be 3/4s
4+4+4/4 = 3
It is 3 3/4
5 ÷ 3/4 = 5 x 4/3 = 20/3 = 62/3
20 4s go into 80.
4 x 20 = 80 4 x 19 = 76 Answer: 19 with 3 remaining
4s=20
number of 4s in 20 = 520 ÷ 4 = 5
15-2, 15-4, 15-6, 15-8 and 12 is 20
The element that completes the 4s sublevel is calcium (Ca). It has the atomic number 20, which means it has 20 electrons. The electron configuration of calcium is (1s^2 2s^2 2p^6 3s^2 3p^6 4s^2), indicating that the 4s sublevel is filled after the 3p sublevel.
Cant do much with this one.9r-4s / 9r+6s9r-4s / 3(3r+2s)
The 4s sublevel is completed by the element calcium, which has an atomic number of 20. In the electron configuration of calcium, the 4s sublevel is filled after the 3p sublevel, resulting in the configuration of 1s² 2s² 2p⁶ 3s² 3p⁶ 4s². Therefore, the completion of the 4s sublevel occurs when two electrons occupy it.
3/4s because a simpler way to say it is .34 with a line over the 3 and 4, and that as a percent is 75% and 75% as a fraction would be 3/4s
There no such phone as an iPhone 4G, only a 4, a 4S, a 3G and a 3-GS
4+4+4/4 = 3
