Answer:
A.
Step-by-step explanation:
Let A and B be the mL of each solution needed.
quantity equation
A + B = 360
concentration equation
0.5A + 0.6B = 0.53(360)
use A = 360 - B for substitution in the other equation.
0.5(360 - B) + 0.6B = 190.8
180 - 0.5B + 0.6B = 190.8
180 + 0.1B = 190.8
0.1B = 190.8 - 180
0.1B = 10.8
B = 10.8/0.1
B = 108 mL
then A+B = 360
A + 108 = 360
A = 360 - 108
A = 252 mL

Y=2x+3
Y=2(0)+3
Y=3
Answer:
B
Step-by-step explanation:
since the strongest correlation is either 1 or negative 1, and weakest is closer to 0,
now, lets order from weakest to strongest:
-0.52,0.65, 0.8, -0.87
Since -0.87 is closest to negative one than others to -1 or 1, it has the strongest linear relationship
14p^2+14q+13p^2
(14p^2 + 13p^2)+(14q)
14+13=27
27p^2 + 14q
