The average wage for an electrician in CA is $25.47/hour. That is 11% above the national average. What is the national average?​
yan [13]

Answer:

$22.95/hour.

Step-by-step explanation:

It is given that the average wage for an electrician in CA is $25.47/hour. That is 11% above the national average.

Let as consider x be the national average.

11% above the national average is

x+\dfrac{11}{100}x=x+0.11x=1.11x

The average wage for an electrician in CA is 11% above the national average. So,

1.11x=25.47

Divide both sides by 1.11.

x=\dfrac{25.47}{1.11}

x=22.945945...

x=22.95

Therefore, the national average is $22.95/hour.

How do you find the perimeter of triangle ABC?
shusha [124]
Alright, so we'll use the Pythagorean Theorem for this one. 
⇒ a²+b²=c² 

The hypotenuse of  a triangle is represented by c² and we're given the values for a and b.  For this triangle, we'll make 15 = a and 20 = b.  Plug this into the equation and we'll have (15)<span>² + (20)² = c ².  This gives us 625 = c</span>².  Solve for c by square rooting both sides of the equation.  √(625) = c.  We now know that c = 25.  To take the perimeter, we add a + b + c ⇒ (15) + (20) + (25) = Perimeter.

-Hope this helps!
