is interest per 1 year? if so:
interest per year=9%×1000
=90
interest for .5 years=90÷2
=45
1000+90+45=1135
Ans: 1135
Since they are similar both dimensions would have the same ratio. The ratio of 5 and 15 is 3. 15 is 3 times larger than 5, so the unknown dimension is 3 times larger than the known dimension.
3 x 10 = 30
The unknown dimension is 30
It is A because the sum of E is 0+5=5 which is greater than 4 and X is 5+0=5 which is greater than four
N represents the quantum number. for n = 3, there are 3 possible sublevels that are 3s, 3p and 3d.
There are four sublevels that are s, p, d and f. In s subshell or sublevel there is 1 orbital, in p sublevel there is 3 orbitals, in d sublevel there is 5 orbitals and in d sublevel there is 7 orbitals.
And there are 2, 6, 10 and 14 maximum number of electrons in s, p, d and f sublevels respectively.
Melanie needs $18 more dollars. joseph has sold 5 boxes which means he has $20 and melanie has sold 3 which means she has $12 so 30-12=18
