6k - 2z = 12

6(4) - 2(6) = 12.
24 - 12 = 12.

K = 4.

<span>6k-2z=12 has two variables (k and z), and thus you can solve for k only in terms of the unknown variable z:

6k = 2z+12, and so  k = (1/3)z + 2 (answer)</span>

A person gets on a Ferris wheel at the starting point. The starting point is 15 feet off the ground. The Ferris wheel has a radi
lisov135 [29]
<h2>Answer:</h2>

\boxed{\frac{25}{2}(\sqrt{6}+\sqrt{2})+65}

<h2>Explanation:</h2>

<em>The height of the rider from the ground after the Ferris wheel</em> equals <em>the starting point is 15 feet off the ground </em><em>plus </em><em>the radius of the Ferris wheel </em><em>plus </em><em>the opposite side of the triangle ΔABC </em>(See figure below).<em> </em>Hence our goal is to find this side. We have the angle 11\pi /2=165^{\circ}, therefore the angle ∠BAC = 165° - 90° = 75°. So this side can be found using trigonometry:

\overline{BC}=\overline{AB}sin(75^{\circ})=50sin(75^{\circ})=\frac{25}{2}(\sqrt{6}+\sqrt{2})

Finally, the height is:

H=\frac{25}{2}(\sqrt{6}+\sqrt{2})+15+50 \\ \\ \boxed{H=\frac{25}{2}(\sqrt{6}+\sqrt{2})+65}

The sales tax rate is 8.25%. Estimate the sales tax<br> on a book that costs $18.50.
eimsori [14]

Answer:

$1.53

Step-by-step explanation:

Sales Tax Rate = 8.25%

Book Sales Cost = $18.50

Book Sales Tax = 8.25% x $18.50

= 8.25/100 x $18.50

= 0.0825 x $18.50

Book Sales Tax = $1.53
