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 
Answer:
2.5 meters per second
Step-by-step explanation:
9x1000=9000m/h
9000/60/60=2.5m/s
Answer:
72/324 or 2/9
Step-by-step explanation:
1/6 is 54/324 and that plus 18/324 is 72/324
Answer:
3.14 (or pi ) feet
Step-by-step explanation:
Entire circle circumference = pi *d = 8 pi feet
45 degrees is a fraction of the entire 360 degrees of the circle
45 / 360 * 8 pi = pi = 3.14 ft
