How many liters of water must Sharon add to 2 liters of a sugar and water solution that is 36% sugar to create a solution that i
Dahasolnce [82]

The amount of sugar x in the starting solution contributes to a 36% concentration, so we have

\dfrac x2=0.36\implies x=0.64

units of sugar in the solution.

Into this solution, Sharon wants to pour y liters of water to obtain a smaller concentration of sugar in the overall solution:

\dfrac{0.64}{2+y}=0.12\implies\dfrac{16}3=2+y\implies y=\dfrac{10}3\approx3.33

So Sharon needs to add \dfrac{10}3 liters of water to the solution to get the desired concentration.

The table shows the relationship between the average number of hours students studied for a mathematics test and their
lina2011 [118]

Answer:

D

Step-by-step explanation:

I'm going to ponder a guess that the numbers shown, 0, 62, 1, 78, 2 ,etc. are part of a table. Having said that, the answers, when graphed, create a sort of parabola, meaning that the function itself is non-linear. This exterminates option A and B. Now its just a matter of seeing which way it goes, and since 78 is higher than 62, and 85 is higher than 78, it obviously increases, rather than decreases. This makes D our final answer.

Find the measure of each angel if m angle 8 = 115º
zalisa [80]
Lines p and q are parallel.
Corresponding angles are congruent.
Each two adjacent angles are supplementary.
Vertical angles are congruent.

Angles 7 and 8 are adjacent, supplementary angles.
m<7 + m<8 = 180
m<7 + 115 = 180
m<7 = 65

Angles 6 and 8 are corresponding angles and congruent.
m<6 = m<8
m<6 = 115

Angles 1 and 6 are vertical angles and congruent.
m<1 = m<6
m<1 = 115
