Mohon bantuannya ' ')/ Dan tolong pakai cara kerja ' ')/

Maaf No 4 tidak dijwb, masih ragu2, klo dijwb takut salah

34. Dengan Perkalian Silang
30 / 45 = 2700 / x
x = 45 . 2700 / 30
= 121500 / 30
= D. 4050 j

Dik :
R1= 3ohm>
R2= 6ohm> >Ket = Paralel
R3= 2ohm>
VPQ = 16 / 2 = 8 Volt
Dit :
I....?
Jwb :
I = V / R
= 8 / (1/3 + 1/6 + 1/2)
= 8 / (2/6 + 1/6 + 3/6)
= 8 / (6/6)
= 8 / (6/6)
= 8 / 1
= D. 8 A

4lampu x 50watt x 8jam x 30hari = 200 x 240 = 48000Wh
1TV x 100watt x 12jam x 30hari = 100 x 360 = 36000Wh

48000Wh + 36000Wh
= 84000Wh
= 84kWh

Jdi 1 kWh = Rp 1000
= 84 kWh x Rp 1000
= Rp 84.000,00
