Not sure when this is from but if it was recent and you still need the answer I believe it’s 1/5.
Answer:
x = 5, y = 20
Step-by-step explanation:
if y = 4x and 3x+2y = 55 then we can subtitude y as x.
We know that y = 4x so we can write 4x wherever we see y.
3x + 2y = 3x + 2(4x) = 55
3x + 8x = 55
11x = 55
x = 5.
And if y = 4x = 4(5)
y = 20
Answer:
The total resistance of these three resistors connected in parallel is
Step-by-step explanation:
The attached image has the circuit for finding the total resistance. The circuit is composed by a voltage source and three resistors connected in parallel: , and .
<u>First step: to find the source current</u>
The current that the source provides is the sum of the current that each resistor consumes. Keep in mind that the voltage is the same for the three resistors (, and ).
The total current is:
The total resistance () is the source voltage divided by the source current:
Now, replace by the previous expression and the total resistance would be:
Simplify the expression and you must get:
The last step is to replace the values of the resistors:
Thus, the total resistance of these three resistors connected in parallel is
