Answer:
1875L = 1.875x10^6 mL
multiply by density to get 2.14x10^6
multiply by percentage to get 6.63x10^4 g of NaCl (66.3 kg)
Step-by-step explanation:
Answer:
Step-by-step explanation:
The two x angles on the right are supplementary which means they add up to 180 degrees
5x + 12 + 7x - 24 = 180
12x - 12 = 180
12x = 192
x = 192/12
x = 18
5x + 12 and y are corresponding angles and are therefore equal
5(18) + 12 = 90 + 12 = 102
Therefore y = 102
They are the zeros have no meaning
So do 21/7 to give you how much they do in a day. The answer is three so they do 3 aceres in a day.
Answer: 4%
