Adrian can put a total of 1716 combinations in the player.
The formula to be used is as follows:
total combinations = n!/[r! *(n-r)!]
n = number of disks available = 13
r = number of disks that be held = 6
= 13! = (13• 12•11•10•9•8•7•6•5•4•3•2•1)/(6! <span>• 7!)
</span>=1716

Step-by-step explanation:
The surface area of a prism is the total area of all its faces.
A triangular prism has three rectangular faces and two triangular faces.
As all 3 sides of the triangle face of this prism are equal, each of the 3 rectangular faces are also equal in area.
<u>Formulae</u>
- Area of a triangle = 1/2 x base x height
- Area of a rectangle = width x length
From inspection of the diagram:
⇒ Area of a triangle = 1/2 x 8 x 7 = 28 in²
⇒ Area of a rectangle = 8 x 10 = 80 in²
<u>Total surface area</u>
Total surface area = 3 rectangle areas + 2 triangle areas
= (3 x 80) + (2 x 28)
= 296 in²
Answer:
15°
Step-by-step explanation:
7x + 12 + 63 = 180
7x + 75 = 180
7x = 180 - 75
7x = 105
x = 15
