Total number of CDs = 12
Number of CDs that can be selected at once = 2
Selecting 2 CDs from 12 means combination of 12 objects taken 2 at a time. This can be calculated by 12C2.
This means, we have 66 possible combinations to choose from

<u>5.59</u>
Step-by-step explanation:
1) let's convert the maximum altitude of the black kite from feet to meters. We can do it by using the following proportion:
From which we find
This is the maximum altitude (in meters) of the black kite. The problem says that the maximum altitude of the red kite is 117.46 m, therefore the red kite is the one with higher maximum altitude.
2) Let's convert the maximum altitude of the red kite from meters to feet, again by using the proportion:
From which we find
Therefore, the maximum altitude of the red kite in feet is 385.37 ft.

Answer:
Area of the slice of pie = 22.09 ft²
Step-by-step explanation:
Area of the slice of pie = Area of the sector of the circle with the central angle 45°
Area of the sector = [Here, r = radius of the circle]
=
= 22.09 ft²
Area of the slice of pie = 22.09 ft²
