Answer:
2/3 liter
Step-by-step explanation:
3.00 g/cm³ = 3.00 kg/L . . . . . . . 1000 g = 1 kg; 1000 cm³ = 1 L
For a mass of 2.00 kg, you need ...
(2.00 kg)/(3.00 kg/L) = 2/3 L ≈ 0.667 L
Answer:
what do u mean, never mind answer is square units
If the mean height of 15 girls is 1.65m, the sum of the girls’ heights is 15×1.65=24.75m.
If the mean height of 10 boys is x metres, the sum of the boys’ heights is 10x m.
The sum of all 25 srudents’ heights is 25×1.682=42.05m.
Therefore, 24.75+10x=42.05, x=(42.05-24.75)/10=1.73m, the mean height of the boys.
