Y=x+4 and y=-2x-2  When they are equal it follows that y=y at that point as well so we can say:

x+4=-2x-2  add 2x to both sides

3x+4=-2  subtract 4 from both sides

3x=-6  divide both sides by 3

x=-2, now we can use this value in either original equation to solve for y.     
y=2

Andrew is building a ramp for a snowboarding competition. The rules of the competition say that the height of the ramp must be 8
lara31 [8.8K]

Answer:

The length of the third piece of the ramp is;

D. 9.24 feet

Step-by-step explanation:

The given parameters are;

The height of the ramp = 8 feet

The angle between the piece that forms height and the base = 90°

The angle formed by the third piece connecting the height of the ramp to the furthest point and the 8 foot piece = 30°

Let 'y' represent the 8-foot piece forming the height, and let 'r' represent the third piece, by trigonometric ratio, we have;

cos(30^{\circ}) = \dfrac{y}{r}

Therefore, we get;

cos(30^{\circ}) = \dfrac{8}{r}

r = \dfrac{8 \ feet}{cos(30^{\circ})} = \dfrac{8 \ feet}{\dfrac{\sqrt{3} }{2}  }  = \dfrac{16 \cdot \sqrt{3} \ feet}{3}  \approx 9.24 \ feet

The length of the third piece, r ≈ 9.24 feet

The regular hexagonal prism tank is completely filled with water. The tank has a height of 5 ft and the area of its base is 22ft
love history [14]

Answer:

110 ft³ of water

Step-by-step explanation:

Use the prism volume formula, V = Bh, where B is the area of the base and h is the height.

Plug in the area of the base and height, and solve for V:

V = Bh

V = (22)(5)

V = 110

So, the volume is 110 ft³

There is 110 ft³ of water in the tank

Under clovis what was the ordeal
Juliette [100K]
<span>The Ordeal was the method used by Clovis, King of the Franks, to determine his judgment of the innocence or the guilt of an accused person. He believed God would be the person's judge in the Floating Test, where the accused would be thrown in a lake and sink if he was innocent or float if he was guilty, or the Boiling Water Test, where the accused would place his hand in boiling water and be considered innocent if the burns healed or guilty if they did not heal well.</span>
