We know that
2 liters of pure water = 0 % of sugar
8 liters of syrup = 48% of sugar

Water = (2 liters x 0%) = 0 total sugar liters
Syrup = (8 liters x 48%) = 3.84 total sugar liters
Total liter mix =8+2-----> 10 liters

Total liters of sugar = 0 + 3.84 = 3.84
if 10 liters-----------> 100%
3.84 liters--------> x
X=3.84*100/10-----> x=38.4%

the answer is
38.4%

a play court on the school playground is shaped like a square joined by a semicircle.the perimeter around the entire play court

Drupady [299]

Answer:

Step-by-step explanation:

Perimeter of square = 182.8 ft

Perimeter of semicircle = 62.8 ft

Let teh side of the square is a and the radius of semi circle is r.

Perimeter of square = 4a

4a = 182.8

a = 45.7 ft

perimeter of semicircle = π r

π r = 62.8

r = 20 ft

Area of square part = a² = 45.7 x 45.7 = 2088.5 ft²

Area of semicircle = πr²/2 = 3.14 x 20 x 20 /2 = 628 ft²

Total area of the play court = 2088.5 + 628 = 2716.5 ft²

The first three steps in determining the solution set of the system of equations algebraically are shown in the table. y = −x2 +

lianna [129]

You have a system of equations $\left \{ {{y = -x^2+2x-9} \atop {y =-6x+6}} \right.$ .

1. Substitude right side of second equation into the left side of the first equation: $-6x+6=-x^2+2x-9$ .

2. Solve this equation:
$x^2-2x+9-6x+6=0, \\ x^2-8x+15=0, \\ D=(-8)^2-4\cdot 1\cdot 15=64-60=4, \\ \sqrt{D}=2, \\ x_{1,2}=\dfrac{8\pm 2}{2 } =3,5$ .

3. Find y:
for $x_1=3, y_1=-6\cdot 3+6=-18+6=-12$ ,
for $x_2=5, y_2=-6\cdot 5+6=-30+6=-24$ .

4. The solutions of the system are: (3,-12) and (5,-24).
Answer: Correct choice is A.
