Let the number of school team members be x, then
(54 - x)/2 + x = 32
54 + x = 32 x 2 = 64
x = 64 - 54 = 10

Therefore, the school has 10 team members.
(54 - 10) / 2 = 44/2 = 22 matches took place in the qualifing round.

22 + 16 + 8 + 4 + 2 + 1 = 53 matches took place by the time a champion is crowned.

The ratio of two complementary angles is 5 to 1. what are the angles?
densk [106]
Call x and y those angles. If they are complementary, then their sum equals 90°:

x + y = 90°

y = 90° - x

The ratio of them is 5 to 1. So,

x/y = 5/1

x/(90° - x) = 5/1

x = 5 * (90° - x)

x = 450° - 5x

x + 5x = 450°

6x = 450°

x = 450°/6

x = 75°

The measure of the other angle is

y = 90° - 75°

y = 15°

The angles are 75° and 15°.

I hope it helps. =)
