Answer:
n = 18 cycles
Step-by-step explanation:
To know how many times does the current oscillates in the given time, you take into account that the number of oscillation can be calculated by using the following expression:
(1)
f: frequency of the oscillation of the current
t: time = 0.30s
The frequency is the number of cycles per second, that is, f = 60 cycles/s
You replace the values of f and t in the equation (1):
In 0.30s the current oscillates 18 times
Answer:
4w + 9
Step-by-step explanation:
Area of rectangle = length x width (or base x height, depending on how you look at it).
It is given to you that:
Area = 8w + 18
Length = 2
Let: width = x
Plug in the corresponding terms with the corresponding words:
8w + 18 = 2x
Isolate the variable, x. Divide 2 from both sides of the equation:
(8w + 18)/2 = (2x)/2
x = (8w + 18)/2
w = (8w)/2 + (18)/2
w = 4w + 9
4w + 9 is the expression that represents the width of the rectangle.

Number times landing on green) = 150 * 1/5 = 30
Number times landing on yellow = 150 * 1/5 = 30
Answer 60 times
<h2>
Answer:</h2>
Like you said, we need to use <u><em>substitution</em></u> to solve for y.
Now that we've solved for y, we can plug in the number we got into one of the <u><em>original</em></u> equations. (You can choose either equation, but I will use the first one.)
Now we have the solution of this system.
