tolong Ya kak No 1-7 Sama caranya

1.
72 × 11 ÷ 9 + 335 - 148
= 792 ÷ 9 + 335 - 148
= 88 + 335 - 148
= 423 - 148
= 275

Jawaban : d. 275

2.
504 = 2³ × 3² × 7

Jawaban : a. 2³ × 3² × 7

3.
3 = 3
4 = 2²
6 = 2 × 3

KPK = 2² × 3
KPK = 4 × 3
KPK = 12

08 : 00 + 12 : 00
= 20 : 00

Jawaban : c. 20 : 00

4.
³√512 × ³√343 ÷ ³√64
= 8 × 7 ÷ 4
= 56 ÷ 4
= 14

Jawaban : b. 14

5.
36 = 2² × 3²
84 = 2² × 3 × 7
120 = 2³ × 3 × 5

FPB = 2² × 3
FPB = 4 × 3
FPB = 12

Jawaban : d. 12

6.
Rusuk Kubus :
Kubus = 12r
r = 288 ÷ 12
r = 24

Volume Kubus :
V = r³
V = 24³
V = 13.824 cm³

Jawaban : d. 13.824

7.
Volume Balok :
V = p × l × t
V = 75 × 50 × 64
V = 240.000 cm³

Debit :
D = V ÷ W
D = 240.000 cm³ ÷ 15 menit
D = 240 liter ÷ 15 menit
D = 16 liter/menit

Jawaban : d. 16

Maaf Kalau Salah

1. D.
    72 x 11 : 9 + 335 - 148
    = 792 : 9 = 88 + 187 = 275

2.A
   504 = 2³ x 3² x 7

3. C.
   KPK dari 3,4,6 = 12 (jam)
   08.00 + 12 jam = 20.00

4. B.
   8 x 7 = 56 : 4 = 14

5. D.
    36 = 2² x 3²
    84 = 2² x 3 x 7
    120 = 2³ x 3 x 5
FPB = 2² x 3 = 12

6.D
  Banyak rusuk kubus = 12
  Panjang 1 rusuk kubus = 288 : 12 = 24
  Volume = rusuk x rusuk  x rusuk = 24 x 24 x 24 cm = 13.824 cm3

7.D.
   Volume = 75 cm x 50 cm x 64 cm = 240.000 cm3 = 240 liter
   Waktu = 15 menit
   Debit = V : W = 240 : 15 = 16 liter/menit
