Answer:

A.) x = 1000 kilowatt-hours

Step-by-step explanation:

Because Micah was charged 113.94 total for the month, this is the y value. We are trying to find x, how much electricity he used. We would start by making the equation: 113.94 = 0.11x + 3.94

Now, we need to get x alone.

(Subtract 3.94 from both sides) 110 = 0.11x

(Divide by 0.11) x = 1000 kilowatt-hours

Hope this helps!

Answer:

$27^{\circ}$

Step-by-step explanation:

Let x represent the sun's angle of elevation.

We have been given that a 6-foot tall man casts a shadow that is 12 feet long.

Upon looking at our attachment we can see that man and his shadow forma a right triangle with respect to ground, where height of man is opposite side and his shadow is adjacent side.

Since tangent relates opposite side of a right triangle with adjacent, so we can set an equation as:

$\text{tan}=\frac{\text{Opposite}}{\text{Adjacent}}$
