Answer:

80%

210%

65%

105%

Step-by-step explanation:

To solve for each of these equations, let's make them fractions first. The denominator will be 20 since that was the goal.

Elena did $\frac{16}{20}$ pushps.

Jada did $\frac{42}{20\\}$ pushups.

Lin did $\frac{13}{20}$ pushups.

Andre did $\frac{21}{20}$ pushups.

To convert this to percentages, let's multiply each by fraction by $\frac{5}{5}$ . This will give us a denominator of 100. The denominator will represent the percentage.

Elena did $\frac{16}{20}$ × $\frac{5}{5}$ = $\frac{80}{100}$ pushps. Elena did 80 percent of the pushups.

Jada did $\frac{42}{20\\}$ × $\frac{5}{5}$ = $\frac{210}{100}$ pushups. Jada did 210 percent of the pushups.

Lin did $\frac{13}{20}$ × $\frac{5}{5}$ = $\frac{65}{100}$ pushups. Lin did 65 percent of the pushups.

Andre did $\frac{21}{20}$ × $\frac{5}{5}$ = $\frac{105}{100}$ pushups. Andre did 105 percent of the pushups.

For n = 3, what are the possible sublevels?

PilotLPTM [1.2K]

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.
