Answer:
Option B - 35.4 VAC
Step-by-step explanation:
Formula for peak voltage is;
V_p = V_rms × √2
Making V_rms the formula, we have;
V_rms = (V_p)/√2
We are given:Peak voltage: V_p = 50 VAC
Where 50 VAC means 50 Volts AC power
Thus;
V_rms = 50/√2
V_rms ≈ 35.4 VAC
So option B is correct
Equation is: 
and Value of x is 
Step-by-step explanation:
We need to write an equation of:
The sum of 3 times a number and 7, divided by 5, is 17
Let the number = x
So, equation will be:
We can solve the equation to find the value of x.
So, Equation is:
and Value of x is

Answer:
x = 1.8
Step-by-step explanation:
10.4 - 5 = 5.4 (subtract 5 from each side)
to isolate the variable, x, divide each side by 3
5.4/3 = 1.8
Answer:
x = 30
Step-by-step explanation:
Vertical angles have equal measures, so ...
2x +10 = 70
2x = 60 . . . . . . subtract 10
x = 30 . . . . . . . divide by 2
After 4 years the rate would have happened 4 times making the initial deposit increase 10%. 10% of 25000 is 2500. So 25000 plus 2500 is $27500.
