Step-by-step explanation:
Answer:
C) 80 milliamperes
Step-by-step explanation:
The amount of current flowing through a circuit is directly proportional to the amount of voltage applied across the circuit. The relation between current(I) and voltage(V) can be expressed as:
Here, is the proportionality constant. It is given that, when voltage is 2 volts, 40 milliamperes( amperes) current flow through the circuit. Using these values we can find the value of proportionality constant. i.e.
Using this value, we can establish the relation between I and V as:
Now, we need to calculate value current (I) if voltage is equal to 4 volts. Substituting V = 4 in above equation, we get:
Thus, the value of current will be 80 milliamperes
Answer:
151.2
Step-by-step explanation:
7x12=84
84/3=28
28x5.4=151.2
Well I think it's c+m=152
Answer:
The angles are supplementary. X = 31
Step-by-step explanation:
The angles sum to equal 180 degrees, menaing they are supplementary. Add the degrees of each side 3x + 25 + 2x = 180 and solve for x. X should equal 31.
