Answer: $\frac{485}{ 1,454}$

Step-by-step explanation:

For this exercuse you need to analize the information provided. You know that:

1) The height of the replica of the Empire State Building with its antenna spire in Las Vegas is 485 feet.

2) The height of the real Empire State building is 1,454 feet.

Finally, in order to find the ratio of height of the replica to the height of the real Empire State building, its necessary to divide the height of the replica of the Empire State Building by the height of the real Empire State building.

Therefore, trough this procedure you get that the ratio of height of the replica to the height of the real Empire State building is:

$ratio=\frac{heigth_{ replica}}{heigth_{real}}=\frac{485}{ 1,454}$

(This fraction cannot be reduced)

Find the radius r of the sphere.

AleksandrR [38]

Given:

The volume of the sphere = 12348π in³

To find the radius of the sphere.

Formula

The volume of a sphere of radius r is

$V = \frac{4}{3} \pi r^{3}$

According to the problem,

$\frac{4}{3} \pi r^{3} = 12348\pi$

Eliminating π from both the side.

or, $\frac{4}{3} r^{3}= 12348$

or, $r^{3}=\frac{(12348)(3)}{4}$

or, $r^{3}=9641$

or, $r=\sqrt[3]{9261}$

or, $r=21$

Hence,

The radius of the sphere is 21 inches.

PQ is parallel to RS. PR and QS are perpendicular to PQ and RS.

galina1969 [7]

When two lines are parallel, the perpendicular distance between them is the same all through the way and the angles formed between the parallel lines and the perpendicular ones joining them is equal to 90 degree.
Example of this is the square or the rectangle as shown below:
AB || BC and both AD and BC are perpendicular on the two lines.
Accordingly, the two perpendicular lines are equal
Based on this, the ratio of PR and QS is 1:1
