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:
17.1 hrs
Step-by-step explanation:
If she tutored 2 1/3hours the first week and 1.5 hours the second week .
That’s 2 1/3 hrs + 1.5hrs
Change 2 1/3 to improper fraction. It becomes
7/5 = 1.4 hrs
1.4 hrs + 1.5 hrs = 2.9 hrs
So she’s tutored 2.9 hrs in the first 2 weeks
Hours remaining for her to tutor this week = hours she tutors every month - hours already done this month
That’s 20 hrs - 2.9 hrs
= 17.1 hrs
She has 17.1 hours more to tutor this month
This triangle can be classified as an Acute Scalene Triangle.
It is an Acute triangle because all of its sides are acute (less than 90 degrees)
It is a Scalene triangle because all of its sides are of different lengths.
To find the missing angle degree we must subtract 61 and 78 from 180. We subtract them from 180 because all angles of a triangle add up to 180 degrees.
180 - 61 - 78 = 41.
So the missing angle (x) = 41 degrees.
