(It might also have helped immensely if you had been listening when this was being explained in class.)
The first pipe fills 1/20 of the tank each minute. The second pipe fills 1/30 of the tank each minute.
Operating together, the two pipes fill ( 1/20 + 1/30 ) of the tank each minute.
In order to add these fractions (or any fractions), you need a common denominator. For these particular ones, ' 60 ' is a good choice.
( 1/20 + 1/30 ) = ( 3/60 + 2/60) = 5/60 = 1/12
The rate of work is 1/12 tankful per minute .
The most sensible choice for the time is 12 minutes.
R x T = W
( 1/12 tankful per minute ) x ( 12 minutes ) = 1 full tank
Two pipes can fill a tank together in 12 minutes. The rate of work for both pipes combined is 12 1 tank per minute. The time required to fill the tank is 12 minutes.

Jawaban:Untuk menghitung biaya total apabila berproduksi 5.000 unit, kita perlu menghitung biaya tetap, biaya variabel, dan total penerimaan. 1. Penerimaan Total:\text{Penerimaan Total} = \text{Harga per unit} \times \text{Jumlah unit} = Rp 10,00 \times 5.000 = Rp 50.0002. Biaya Variabel:\text{Biaya Variabel} = 40\% \times \text{Penerimaan Total} = 0,40 \times Rp 50.000 = Rp 20.0003. Biaya Total:\text{Biaya Total} = \text{Biaya Tetap} + \text{Biaya Variabel} = Rp 4.000 + Rp 20.000 = Rp 24.000 Jadi, biaya total apabila berproduksi 5.000 unit adalah Rp 24.000. Jika Anda ingin gambaran visual dari perhitungan ini, saya akan menghasilkan gambar untuk Anda.
