A glider begins its flight 1 1/2 miles above the ground. After 60 minutes it is at 1 mile above ground a glider begins its fligh

t 1 1/2 miles above the ground. After 60 minutes, it is 1 mile above the ground.
Find the change in height of the glider. If it continues to descend at the rate, how long does the entire descent last until the glider reaches the ground?

It changed 1/2 a mile every hour (60 minutes) So it will take 3 hours (180 minutes) to reach the ground level.

K<br> M<br> N<br> L <br>Radius:13<br> Diameter:26 cm <br>Circumference:?<br> Area:?
Step2247 [10]

Answer:

Given radius (R) = 13

Diameter =  2R =  26

Circumference =  2πR

=  26π

=  81.681408993335

Area =  πR2

=  169π

=  530.92915845668

Step-by-step explanation:

While a circle, symbolically, represents many different things to many different groups of people including concepts such as eternity, timelessness, and totality, a circle by definition is a simple closed shape. It is a set of all points in a plane that are equidistant from a given point, called the center. It can also be defined as a curve traced by a point where the distance from a given point remains constant as the point moves. The distance between any point of a circle and the center of a circle is called its radius, while the diameter of a circle is defined as the largest distance between any two points on a circle. Essentially, the diameter is twice the radius, as the largest distance between two points on a circle has to be a line segment through the center of a circle. The circumference of a circle can be defined as the distance around the circle, or the length of a circuit along the circle. All of these values are related through the mathematical constant π, or pi, which is the ratio of a circle's circumference to its diameter, and is approximately 3.14159. π is an irrational number meaning that it cannot be expressed exactly as a fraction (though it is often approximated as 22/7) and its decimal representation never ends or has a permanent repeating pattern. It is also a transcendental number, meaning that it is not the root of any non-zero, polynomial that has rational coefficients. Interestingly, the proof by Ferdinand von Lindemann in 1880 that π is transcendental finally put an end to the millennia-old quest that began with ancient geometers of "squaring the circle." This involved attempting to construct a square with the same area as a given circle within a finite number of steps, only using a compass and straightedge. While it is now known that this is impossible, and imagining the ardent efforts of flustered ancient geometers attempting the impossible by candlelight might evoke a ludicrous image, it is important to remember that it is thanks to people like these that so many mathematical concepts are well defined today.

MARK AS BRAINLEST!<br> 5 + x = 5
n200080 [17]

Answer:

  x = 0

Step-by-step explanation:

You know the answer to this because you know the identity element for addition is 0: 5 + 0 = 5.

__

Or, you can make use of the addition property of equality and add -5 to both sides of the equation:

  5 - 5 + x = 5 - 5

  x = 0 . . . . . . . . . . simplify
