Question

Frekuensi matematika no 23 24 dan 25

Answer 1

23. 60°+30°+45°+90°= 225°
360°-225°= 135°
135/360 . 72 = 27 orang

24. 60°+70°+115°+45°+50° = 340°
360°-340° = 20° (sabtu)
20/360 . x = 56
20x = 56.360
20x = 20.160
x = 20.160/20
x = 1.008 (jumlah total pengunjung dari senen sampe sabtu)
115°/360° . 1.008 = 322 orang

25. robotik ubah ke persen:
90°/360° .100% = 25%
30%+20%+5%+25% = 80%
100%-80% = 20% (biola)
20/100.250 = 50 orang
