Lösungen

1.

sqrt(24² + 45²) < 50 ?

sqrt(2601) < 50

51 < 50 NOT!!!!

2.

60 cm = b

h = ?

60 : h = 16: 9

60*9 = 16 * h

h = 33,75

d = sqrt(h² + b²)

d = 68,84cm

68,84cm / 2,54 = 27,10 zoll = 27'

3.

kleines teilstück oben

26,2 – 10,5 = 15,7

x = √32,6² + 15,7²

x = 36,2

U = a + b + c + x

U = 95 m

K = 95 * 6,7 = 636,5€

4.

350² + 85² = l ²

l = 360,1 m

t = 360 ,1 / 11 = 32,74 s

5.

U = 2 a + c = 4 + 3 = 7 teile.

1 teil = 42 : 7 = 6

c= 18cm a = 12cm

h= sqrt(12² – 9²) = 7,93 cm

A = 71,43 cm²
