6:15 to 7:15 = $12 for the hour
7:15 to 7:45 Is a half hour = $6
So total $12 + $6 = $18
For the answer to the question above, <span>Well, first let us put up a functional equation. </span>
<span>Since this is an exponential function, it'll be: f(t)=54,000*1.03^t </span>
<span>But we want to know how many wolves there were 10 years ago. </span>
<span>For that, we simply "turn time around", as in: f(t)=54,00*1.03^-t </span>
<span>This displays a decreasing number of wolves, as you turn back time. </span>
<span>Now we simply calculate 54,000*1.03^-10 </span>
<span>which is approximately 40,200?</span>
First you would multiply left to right. So 50*3 is 150 and then 150*3 is 450. 450*20 is 9000. 9000 is your answer.
First covert 39.5% to a decimal to get 0.395.
0.395 written as a fraction is

to get
Is each line parallel, perpendicular, or neither parallel nor perpendicular to a line whose slope is −6?
Parallel, slope is the same, perpendicular slope is opposite and reciprocal
so
line n, with slope −6 , same slope -----> Parallel
line p, with slope 1/6 , opposite and reciprocal -----> Perpendicular
line q, with slope −1/6 , -----> Neither
line m, with slope 6, -----> Neither
