The 7th tower will be 161 cm tall. You take 115 and divide it by 5 and then you get how much each cube is ,then you get 23 per cube then you multiply 23 by 7 and that's how you  get your answer.

What are the values of x in the equation 4x2 4x – 3 = 0? x = –1.5, 0.5 x = –0.5, –1.5 x = x =?
Stolb23 [73]

Answer:

The values of x are

x=-1.5\ , 0.5

Step-by-step explanation:

we have

4x^{2}+4x-3=0

Group terms that contain the same variable, and move the constant to the opposite side of the equation

4x^{2}+4x=3

Factor the leading coefficient

4(x^{2}+x)=3

Complete the square. Remember to balance the equation by adding the same constants to each side.

4(x^{2}+x+.25)=3+1

4(x^{2}+x+.25)=4

(x^{2}+x+.25)=1

Rewrite as perfect squares

(x+0.5)^{2}=1

Square root both sides

x+0.5=(+/-)1

x=-0.5(+/-)1

x=-0.5+1=0.5

x=-0.5-1=-1.5

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}
