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%

The concentration of the solution, when Maria, added 2 liters of pure water to 8 liters of a 48% sugar syrup is 38.4%.

What is allegation?

Allegation is a method to find the ratio in which two or more indignant are mixed to produce a mixture or solution.

As, Maria added 2 liters of pure water with 8 liters of water, which has 48% sugar syrup. The total amount (in liter) of the mixture is,

$w=8+2\\w=10\rm liters$

Maria has 2 liters of pure water, which has no or zero liters of sugar syrup, and she has 8 liters of water, which has 48% sugar syrup. Therefore, the total amount of sugar syrup is,

$s=0+8\times\dfrac{48}{100}\\s=3.84\rm liters$

There is total 10 liters of water in which 3.84 liters is the amount of sugar syrup. Therefore, the concentration of the resulting solution is,

$c=\dfrac{3.84}{10}\times100\\c=38.4\%$

Hence, the concentration of the solution, when Maria, added 2 liters of pure water to 8 liters of a 48% sugar syrup is 38.4%.

2. angles qrt and qst both measures 156 degrees.

step-by-step explanation:

we have been given a diagram of a circle and we are told that measure of arc qvt is 156 degrees.

we can see from our given diagram that angle qrt and angle qst subtends to arc qvt.

since we know that angles subtended by the same arc at the circumference are always equal.

by angle subtended by same arc theorem, measure of angle qrt and angle qst will be equal to the measure of arc qvt.

$m\angle qrt=156^o$

$m\angle qst=156^o$

therefore, angles qrt and qst both measures 156 degrees and 2nd statement is the correct choice.
