Answer:
k > -9
Step-by-step explanation:
Subtract 12 from both sides as we want to isolate k-
30 - 12 = 18
-2k < 18
Divide both sides by -2
18/-2 = -9
k > -9
Could you show the problem, please? :)
Density of water = 1000 kg/m^3
1 m^3 = 1000 litres
Therefore,
1000 kg/1000 l => 1 kg/l => 1000 g/l
Then, 300 g of water = 300/1000 l = 0.3 l
The concentration of the syrup = mass/amount of water = 60 g/0.3 l = 200 g/l
Answer:
14.4
Step-by-step explanation:
To find 40 percent of 36, here's how I do it. Just divide 36 by one hundred (move the decimal point two times to the left), giving you 0.36. Then multiply that by 40, and you get 14.4! Of course, there are multiple ways to do it, but that's just mine. If it doesn't work for you, try and search some formulas.
