Let's make ;
A = ounces solution A
B = ounces solution B
total number of ounces:
A + B = 120
concentration:
0.65A + 0.80B = 0.7(120)
Substitute A for 120 - B in the second equation to combine them.
0.65(120 - B) + 0.80B = 84
78 - 0.65B + 0.80B = 84
0.15B = 84 - 78
0.15B = 6
B = 6/0.15
B = 40 ounces
Then... A = 120 - 40
A = 60 ounces
B. It increases the genetic diversity. Sexual reproduction provides genetic diversity because the egg and sperm produced contain different combinations.
Acceleration is defined as velocity per unit time.
Here, a=acceleartion,
v=velocity=36 m/s
t=time=12 s
A car at rest ends accelerates for 12 seconds. After this time the car is going 36 m/s. So acceleration that is a=3 ms⁻².
