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
Problem 16
Divide both sides by 2 to undo the multiplication of 2 (done to the t).
2t > 324
2t/2 > 324/2
t > 162
Answer: t > 162
=====================================================
Problem 17
Similar to problem 16, we will divide both sides by 12
12y >= 1
12y/12 >= 1/12
y >= 1/12
Answer: y >= 1/12
Note: the symbol ">=" without quotes means "greater than or equal to".
=====================================================
Problem 18
To undo the division of 9.5, we multiply both sides by 9.5
x/9.5 < 11
9.5*x/9.5 < 9.5*11
x < 104.5
Answer: x < 104.5
