A 20,15, 30 amp single-pole snap switch is permitted to be used to control a lighting circuit that pulls 15 amps. Option D is correct. This is further explained below.
<h3>What is Ampere?</h3>
Generally, Ampere is simply defined as the basic metric SI unit of electrical current
A 20,15, 30 amp capacity will suffice because these capacities are equal to greater than the load in question.
In conclusion, To operate a 15-amp lighting circuit, a single-pole snap switch rated for 20, 15, or 30 amps is legal.

Answer:
Number 1 can form a right triangle. Numbers 2 & 3 cannot.
Step-by-step explanation:
To check if the sides are a right triangle, check if the sum of the squares of the two smaller sides equals the length of the square of the longest side. In other words, do the Pythagorean Theorem.
5² + 12² = 13²
25 + 144 = 169
169 = 169
<u><em>They are equal therefore Number 1 can form a right triangle.</em></u>
5² + 7² = 9²
25 + 49 = 81
74 = 81
<em>They are not equal, therefore Number 2 can't form a right triangle.</em>
<em />
10² + 12² = 30²
100 + 144 = 900
244 = 900
<em>They are not equal, therefore Number 3 can't form a right triangle.</em>
Answer: 6.8%
Step-by-step explanation:
We need to find both percentage so we can determine the increase.
Finding percentage of $10 return: 1% return
Finding percentage of $78 return: 7.8% return
To find the percent increase we do 7.8%-1.0% = 6.8%
The answer would be “Greater than.”
