Answer:

\frac{x}{y} \frac{5x}{\frac{x^{2} -4}{\frac{8x}{x+2} } }\\\\=\frac{5x(x+2)}{8x(x^{2} -4)}\\\\=\frac{5(x+2)}{8(x+2)(x-2)}\\\\=\frac{5}{8(x-2)}\\\\=\frac{5}{8}.\frac{1}{x-2}

Step-by-step explanation:

\frac{ \frac{5x}{ {x}^{2} - 4 } }{ \frac{8x}{x + 2} }  =  \frac{5x}{ {x}^{2} - 4 }  \times  \frac{x + 2}{8x}  =  \frac{5x + 10}{ {8x}^{2}  - 32}   \\

hope it helps:)

Which company’s tower holds the most water?
GuDViN [60]

Answer: First Option

Step-by-step explanation:

The formula to calculate the volume of a cylinder is:

V = \pi(\frac{d}{2})^2*h

Where d is the diameter of the cylinder and h is the height.

Notice that the term d is squared. This means that to increase the volume of a cylinder it is more efficient to increase its diameter as well. Therefore, look for the cylinder with the largest diameter among the options.

The first cylinder is 90 ft in diameter and 40 ft in height and its volume is

V = \pi(\frac{90}{2})^2*40

V=254469\ ft^3

You can verify that it is the tank that has the highest volume

A 17 ft ladder leans against the side of a house. The top of the ladder is 14 ft off the ground. Find x, the angle of elevation
kari74 [83]

Answer:

55.4

Step-by-step explanation:

Think of it as a right angled triangle, the length of the ladder (17ft) is the hypotenuse, the length of the ground (14ft) is the rise, we then use sin to get the angle as the angle of elevation is the angle between the ladder and the ground hence sin^-1 (14/17) and you get your angle.

How can you determine which of two lines will be steeper from
Romashka-Z-Leto [24]
Well on a table of data, if the y coordinates increase a lot over a short x distance then it will be steep.

In an equation, you would put it into y = mx + b form and whatever your m is will be your slope. If m is large, it will be steep.

A cube whose edge is 20 cm 1 point
Sav [38]

Answer:

Unpainted  surface area = 514.28 cm²

Step-by-step explanation:

Given:

Side of cube = 20 Cm

Radius of circle = 20 / 2 = 10 Cm

Find:

Unpainted  surface area

Computation:

Unpainted  surface area = Surface area of cube - 6(Area of circle)

Unpainted  surface area = 6a² - 6[πr²]

Unpainted  surface area = 6[a² - πr²]

Unpainted  surface area = 6[20² - π10²]

Unpainted  surface area = 6[400 - 314.285714]

Unpainted  surface area = 514.28 cm²
