Answer:
The mass of half a liter of water is 500g, that is, 0.5kg.
Step-by-step explanation:
Density is mass divided by the volume, that is:
Here, we have to be careful. Since the density is in grams per cm³, m has to be in grams and v in cm³.
We have that:
What is the mass of half a liter of water?
One liter is 1000 cm³.
So half a liter is 1000/2 = 500 cm³, which means that 
Then
The mass of half a liter of water is 500g, that is, 0.5kg.
Answer:
36 and 54
Step-by-step explanation:
54-36=18
54+36= 90
Answer:
(38.1,88.6)
Step-by-step explanation:
We are given the following in the question:
Sample mean, 
= 38.3
Sample size, n = 695
Alpha, α = 0.05
Population standard deviation, σ = 3.6
95% Confidence interval:
Putting the values, we get,
20m measurement that’s what is equal to 10
Step-by-step explanation:
equation.
2(m+10)=4(m−15)
(2)(m)+(2)(10)=(4)(m)+(4)(−15)(Distribute)
2m+20=4m+−60
2m+20=4m−60
Step 2: Subtract 4m from both sides.
2m+20−4m=4m−60−4m
−2m+20=−60
Step 3: Subtract 20 from both sides.
−2m+20−20=−60−20
−2m=−80
Step 4: Divide both sides by -2.
−2m−/2=−80/−2
m=40
