The answer is 40 miles per hour. If you divide 1200/30 you would get 40. Hope this helps!
The pH value of a solution is a logarithmic function of the hydronium ion concentration in the solution. Since we are given the pH foe both we can easily calculate the H+ ion concentration as follows:
Aeen
3.3 = -log (H+)
H+ = 0.04 M
Marien
2.7 = - log (H+)
(H+) = 0.07 M
Therefore, Aeen's drink is 0.07/0.04 or 2 times more hydrogen ion concentration than Marien's drink.
Answer:
Y= -1.5x+3
Step-by-step explanation:
(Y-Y1)=m(x-x1)
0-3=m(2-0)
m= -1.5
Y= -1.5x+B
when y=3 and x=0 b=3
Answer:
All systems have 2 real solutions.
Explanation: there are X and Y unknowns.
<span>First let us answer it as if the input is 12. Then the output is 36. F(12)=36 If the input is 13, then the output is 39. F(13)=39 So we know the answer is between 36 and 39 The output of 12.5 is the same as the output of 12 plus the output of .5 F(12.5) =F(12) + F(.5) = 36 + 1.5 =37.5 So the question is really what is the output of .2 F(12.2) = …<span>The same as Y=3X with X being the input.</span></span>
