To answer this item, let x be the amount of water. The concentration (in % sugar) of the solution is calculated by dividing the amount of sugar by the total amount. That is,
C = (S/ (S + x))(100%)
Substituting the known values to the equation,
75 = ((0.5/(0.5 + x))(100%)
The value of x from the equation is 0.167.
<em>Answer: 0.167 lbs of water</em>
Answer:
bro there shld be a picture because you said in the figure. Without figure we can't know how will we do
Step-by-step explanation:
i think the ans is 57°
The question above may be answered through the concept of ratio and proportion. The ratio between the population of a certain city and the radius of the circle used should be proportional. Mathematically,
19465000/5 = 37691000/x₁ = 25,675,000/x₂
The values of x₁ and x₂ are 9.7 cm and 6.6 cm, respectively.
Sine (Angle K) / side k = sine (105) / 4.7
Sine Angle K = (2.7 * 0.96593) / 4.7
Sine Angle K =

Angle K = 33.704 degrees
Angle J = 180 -105 -33.704 = 41.296
Sine J / side (j) = sine (105) / 4.7
Sine (41.296) / side (j) = 0.96593 / 4.7
Side (j) = Sine (41.296) / 0.96593 / 4.7
Side (j) = 0.65995 /
