Step-by-step explanation:
To convert the given measurements, we can use the following conversions:
1 km = 1000 m
1 L = 100 cL
1 kg = 100000 cg
1 hm = 10000 Mm
1 mm = 0.1 dm
1 dL = 1000000 UL
1 g = 1000 mg
1 dg = 10 dag
1 hm = 10000 mm
1 nl = 0.000001 L
Let's convert each measurement step by step:
8.90 km to m:
8.90 km = 8.90 * 1000 m = 8900 m
0.00043 L to cL:
0.00043 L = 0.00043 * 100 cL = 0.043 cL
46.90 kg to cg:
46.90 kg = 46.90 * 100000 cg = 4690000 cg
49.05 hm to Mm:
49.05 hm = 49.05 * 10000 Mm = 490500 Mm
0.1547 mm to dm:
0.1547 mm = 0.1547 * 0.1 dm = 0.01547 dm
0.000000343 dL to UL:
0.000000343 dL = 0.000000343 * 1000000 UL = 0.343 UL
4.72x10^-9 g to mg:
4.72x10^-9 g = 4.72x10^-9 * 1000 mg = 0.00000472 mg
6.39x10^-11 dg to dag:
6.39x10^-11 dg = 6.39x10^-11 * 10 dag = 6.39x10^-10 dag
67.3 hm to mm:
67.3 hm = 67.3 * 10000 mm = 673000 mm
1.3x10^-9 nl to L:
1.3x10^-9 nl = 1.3x10^-9 * 0.000001 L = 0.0000000013 L
Now, let's solve the density problems:
1. D = ?
2. D = 0.56 kg/mL
3. D = 1.78 kg/cm3
For the volume calculations:
V = 94.9 mL
V = ?
V = 96.45 cm3
For the mass calculations:
m = 75.45 g
m = 34.76 kg
m = ?
