percent ---------------- quantity
Acid type I 60.00% ---------------- x liters
acid type II 30.00% ------ 60 - x liters
Mixture 40.00% ---------------- 60
Total 60 liters
60.00% x + 30.00% ( 60 - x ) = 40.00% * 60
60 x + 30 ( 60 - x ) = 2400
60 x + 1800 - 30 x = 2400
60 x - 30 x = 2400 - -1800
30 x = 600
/ 30
x = 20 liters 60.00% Acid type I
40 liters 30.00% acid type II

Answer:
x=77
Step-by-step explanation:
The answer is B. <R is congruent to <X.
Answer:
10
Explanation:
The average rate of change is calculated using
∣∣
∣
∣∣¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯aag(b)−g(a)b−aaa∣∣∣−−−−−−−−−−−−−−−
here a = 1 and b = 3
g(3)=2(3)3−4(3)2=54−36=18
and g(1)=2(1)3−4(1)2=2−4=−2
⇒ average rate of change =18−(−2)3−1=202=10
Hope this helped
