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:
<u>The sum of their ages now is 13</u>
Step-by-step explanation:
Dally's age = x
Dilly's age = x - 7
In 4 years time Dilly will be half Dally’s age, therefore:
Dilly's age plus four equals to half of Dally’s age plus four,
replacing with the values and variables we know:
x - 7 + 4 = (x + 4) /2
x - 3 = (x + 4) /2
2x - 6 = x + 4 (Multiplying by 2 at both sides)
2x - x = 4 + 6 (Like terms)
x = 10 ⇒ x - 7 = 3
<u>The sum of their ages now is 13 (10 + 3)</u>
2x - 3(x + 4) = -5
2x - 3x - 12 = -5
-x - 12 = -5
-x = -5 + 12
-x = 7
x = -7
The answer is: x = -7.
