Answer:
Magnetism and electricity involve the attraction and repulsion between charged particles and the forces exerted by these charges. The interaction between magnetism and electricity is called electromagnetism. The movement of a magnet can generate electricity. The flow of electricity can generate a magnetic field.

<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 
, therefore the angle ∠BAC = 165° - 90° = 75°. So this side can be found using trigonometry:
Finally, the height is:
1. 3/5
2. doesnt simplify
3.3/32
Answer:
Consistent dependent
3x - 3y = 6 and -x + y = -2
Step-by-step explanation:
<u>Inconsistent</u>: parallel lines, no solutions
<u>Consistent dependent</u>: same line, infinite solutions
<u>Consistent independent</u>: intersects at one point, one solution
Therefore, the pair of lines are Consistent dependent
From inspection of the diagram:
The lines will have equivalent equations.
Therefore, the solution is 3x - 3y = 6 and -x + y = -2
Because:
3x - 3y = 6 ⇒ y = x - 2
-x + y = -2 ⇒ y = x - 2
Answer:
$83.97
Step-by-step explanation:
Let's find the total thickness of all 42 books first. To do this, we do 42 * 1.75 = 73.5 inches. We know that each shelf is 3 feet long, but we want to convert to the same unit so that it's easier to calculate, so each shelf is 3 * 12 = 36 inches long. Now, to find the number of shelves needed, we'll do total thickness/length of each shelf which is 73.5 / 36, or 2.04. Our answer has to be an integer (because you can't have half of a shelf), so do we round up or down? Well, if we rounded down, then there wouldn't be enough room for all the books, so we round up to 3 shelves instead. Because each shelf is $27.99, the price for 3 will be 27.99 * 3 = $83.97. Hope this helps!
