1. The complex number 6 + 7i has
- real part 6;
- imaginary part 7.
2. The complex number 10 + 2i has
- real part 10;
- imaginary part 2.
3. When we add two complex numbers, we add real parts and imaginary parts separately:
(6+7i)+(10+2i)=(6+10)+(7+2)i=16+9i.
Answer: 16+9i
15) x=31/10
16)x=2
17)x=16/3
18)x=-2
19)2.5 hours
20) 32 hours
To find out the answer we divide 0.09 by 10:
÷10=0.009.
Therefore, 0.09 is 10 times as much as 0.009.
To convert cm³ to m³, you can break down the units.
cm³ = cm x cm x cm
Each cm is converted to m so :
m³ = m x m x m
= 1/100 x 1/100 x 1/100
= 0.000001
So, 1cm³ is 0.000001m³, so to convert cm³ to m³ you divide your value by 1,000,000 and vice versa.
1. 0.35m³
2. 8m³
3. 43.34m³
4. 30m³
5. 0.77m³
