Question

Tolong dijawab no.16 & 17 ..
yg gk bisa jwb nggk ush jwb

Answer 1

16) volume = debit*waktu
=> (28 + 24) * 35
=> 1820
volume sisa = 2400 - 1820 = 580 liter (d)

17) volume akhir - volume awal
= 2148 - 420 = 1728 dm3

3/5 jam = 3/5 * 60 = 36 menit
debit = volume/waktu
=> 1728/36 = 48 liter/menit
jumlah pipa = 2
debit tiap pipa
= 48 / 2 = 24 liter/menit (B)
#note : dm3 = liter


THANKS!

Answer 2

Nomor 16
Diketahui:
Volume = 2.400 liter
debit 1 = 24 liter/menit
debit 2 = 28 liter/menit
waktu = 35 menit

Penyelesaian
sisa = volume awal - volume yang berkurang
sisa = 2.400 - debit x waktu
sisa = 2.400 - (24+28) x 35
sisa = 2.400 - 52 x 35
sisa = 2.400 - 1.820
sisa = 580 liter
JAWABAN D.

Nomor 17
Diketahui:
Volume awal= 420 dm³
debit 1 = debit 2 = debit
Volume akhir = 2.148
waktu = 3/5 jam
waktu = 3/5 x 60 menit
waktu = 36 menit

Penyelesaian:
debit = volume : waktu
debit 1 + debit 2 = volume : waktu
debit 1 + debit 1 = volume : waktu
2 × debit 1 = volume : waktu
2 × debit = (2.148-420) : 36
2 × debit = 1.728 : 36
2 × debit = 48
debit = 48/2
debit = 24 dm³/menit
debit = 24 liter/menit
JAWABAN B.
