Answer:
Step-by-step explanation:
Let l litre of 7 grams of salt per litre is combined with x litres of water which contains y grams of salt per litre to yield a solution with 2 grams of salt per litre.
Thus,
Salt in l litre + salt in x litre = salt in resultant mixture
7l + xy = 2(l +x)
7l + xy = 2l + 2x
7l - 2l = 2x - xy
5l = x(2-y)
Hence, 
litres of 7 gram of salt per litre is mixed.
4 (of whatever your mathematical unit is)
you times 4500 by 0.0575 and then divide 1035 by that number and then you get 4.
Answer:
Measure of the unknown angle is 21°.
Step-by-step explanation:
In the given question,
Measure of opposite side and the measure of hypotenuse have been given.
Therefore, we will use the trigonometric ratio for the unknown angle which has the ratio of opposite side and the hypotenuse.
Therefore, measure of the unknown angle is 21°.
