A chemist wants to mix a solution of 20% chlorine with a solution of 60% chlorine to make 120 liters of 30% solution of chlorine
Mama L [17]

Answer:

90 and 30 liters

Step-by-step explanation:

1) if solution of 20% is 'x' and of 60% is 'y' liters, then

2) the pure chlorine is: for solution of 20% - 0.2x, for solution of 60% - 0.6y and

3) the mix of the two solutions is 120=x+y.

4) using these items it is possible to make up the system of two equations:

\left \{ {{x+y=120} \atop {0.2x+0.6y=0.3(x+y)}} \right.

5) finally, x=90 liters of 20%; y=30 liters of 60% solution.

What is the best prediction of the amount of money earned when the lemonade stand has been open for 9 hours
abruzzese [7]

Answer:  $50

Step-by-step explanation:  Draw a line through the apparent center of the scattered dots. See where that line intersects 9 in the time scale (x-axis numbers) and the dollars earned scale (y-axis numbers)

It could be 50 or 55, but since there are a few more dots below the apparent midline, it may be best to use the lower estimate.

In the square below, the two semi-circles are congruent. Find the area of the shaded region. If necessary, round your answer to
Jobisdone [24]
Let's start with the area of the square
area \: square = s \times s = 8 \times 8 = 64
now let's subtract the are of the two half circles.
two half circles are the same as one circle, and we know that the diameter of the circle is 8 (same as the side of a square) so it's radius is 8/2= 4 inches

area \: circle = \pi {r}^{2}  = \pi \times  {4}^{2}  = 16\pi
now we just subtract and our answer is

64 - 16\pi = 64 - 16 \times (3.14) = 13.73
