Answer:

£9.80

Step-by-step explanation:

The calculation of the total value is given below:

Provided that that

The value of 20p coins is £2.80

So 1p = £2.80 ÷ 20

Crank
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

PLEASE HELP HURRY WITH THE QUESTIONS BELOW!!!!!
AnnZ [28]

From left to right, the answers are:  152, D(line e), C(obtuse), 44 degrees.

Now I feel guilty and sleezy.  Giving answers alone without explanations
is something I almost never do, because it doesn't help anybody do
anything but cheat.  But it's all I have time for right now.  If a mod comes
along and decides to delete this because of no explanations, then let him
delete it.  It'll serve us right, you and me both.

A triangular bandana has an area of 46 square inches. The height of the triangle is 5 3 4 inches. Enter and solve an equation to
shutvik [7]

Answer: 16 inches

Step-by-step explanation:

The area of a triangle = bh/2

where b = base = unknown

h = height = 5 3/4 inches

Area = 46 inches²

Therefore, 46 = base × 5 3/4 / 2

Cross multiply

46 × 2 = base × 5 3/4

92 = base × 5 3/4

Base = 92 ÷ 5 3/4

Base = 92 ÷ 23/4

Base = 92 × 4/23

Base = 4 × 4

Base = 16 inches
