There is a 3 hour difference in travel time.
So if x is the speed of the freight train and distance is 240 miles...
3(3x)-3x=240
9x-3x=240
6x=240
x=240/6
x= 40mph for the freight train..
passenger train is 3 times faster than the freight..
3×40=120mph

<em>Ohhh, interest problems. I haven't done an equation like this in a long time, but I will attempt.</em>

<em>I would say that the answer is the 2nd option. The equation is i = (5200)(0.06)(2.5).</em>

<em>The traditional interest formula is I = (P)(R)(N).</em>

<em>P = the original amount of money given</em>

<em>R = interest rate</em>

<em>N = the amount of time</em>

<em>I hope this answers your question (and that I understood the question correctly!).</em>

For the first problem, the answer is D, because every year, the graph goes down by about $4,500.
For problem two, 
a. It's located in quadrant one because x and y are both positive (I've attached a graph with labeled quadrants for reference)
I'm unsure about b and c but I hope I helped with the others!

7. Patrick tosses a penny and a number cube, with faces numbered 1 through 6, at the
lions [1.4K]

Answer:

B. 1/3 or 33.3%

Step-by-step explanation:

<em>H-</em> 1 ,2 ,3, 4, 5, 6

<em>T-</em> 1, 2, 3, 4, 5, 6

Multiples of <em>3:</em> 3, 6, 9, 12, etc..

<em>2/6 simplified is 1/3 </em>

So, the probability that the penny will land on heads and the number cube will land on a multiple of 3, is 1/3 or 33.3%
