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.

Y=-x^2-x-3 find the X intercept for The parabola define by this equation
KengaRu [80]
To find the X intercept make y =0. Then factor out a negative on the side with the equation for each of the terms, so it becomes
0=-(x^2+x+3)
0=(x^2+X+3)
0-3=(x^2+X)
-3=x(X+1)
-3=X, X intercept -3,0
-3=(X+1)
-4=X, X intercept -4,0.
These are possible X intercepts you can check by using quadratic formula as well.

Find the value of x in kite EFGH<br>​
kolbaska11 [484]

Answer:

x = 105

Step-by-step explanation:

the sum of all interior angles of any four-sided figure has 360 degrees

∡F and ∡H are equal

add all four expressions and set them equal to 360

x + (x + 5) +( x + 5) + (140 - x) = 360

combine like terms

2x + 150 = 360

2x = 210

x = 105

Answer:

Cost = 112.266 cent/km

Step-by-step explanation:

Given

Unit\ cost = R17.82/litre

Rate = 6.3litre/100km

Required

The fuel cost in cent\ per\ km

This is calculated using:

Cost = Unit\ cost * Rate

Cost = R17.82/litre * 6.3litre/100km

Cost = R17.82 * 6.3/100km

Cost = R1.12266/km

Multiply by 100 to get the cost in cents

Cost = 1.12266 * 100 cent/km

Cost = 112.266 cent/km
