To figure this out you could use trial and error. I started with trying 60 mph for the freight train which means the passenger train would go 180 mph. This gave me too big of a difference (540-180 after they each travel three hours).

Then I tried 50 mph and 150 mph, and it was still too big(450-100).

When I did 40 mph it was 120 travel miles for the freight train, and 360 travel miles for the passenger train. This was the difference of 240 miles that was needed.

So the freight train traveled 40 mph and the passenger train traveled 120 mph.

The table below shows the amount of lemon juice and sugar needed to make three different-sized batches of lemonade using the sam
mash [69]

Answer:

<u>j = 2.5s</u>

Step-by-step explanation:

1. Let's review the information given to us to answer the question correctly:

                Lemon juice (mL)      Sugar (gr)

Batch A        500                             200

Batch B         750                             300

Batch C       1,500                             600

2. Write an equation to describe the relationship between j, the amount of lemon juice in mL, and s, the amount of sugar in g.

Ratio = Amount of lemon juice/Amount of sugar

Ratio = 500/200 = 750/300 = 1,500/600

Ratio = 2.5

Now, we can write the equation, this way:

<u>j = 2.5s</u>

taurus [48]
For this case what you should know is that the distance between two points can be thought of as a line. To find the length of this line, you can use the formula:
 d: √ [(x2 - x1) ^ 2 + (y2 - y1) ^ 2]
 Example,
 for points (1.0, 2.0) and (1.0, 5.0):
 d: √ [(1 - 1) ^ 2 + (5 - 2) ^ 2]
 d: 3.0
 Answer:
 the distance between point (x1, y1) and point (x2, y2) is:
 d: √ [(x2 - x1) ^ 2 + (y2 - y1) ^ 2]

The length of the diagonal of a rectangle is √181 inches. ​ ​Which statement describes the length of the diagonal?
lakkis [162]

Answer:

The correct option is (B).

Step-by-step explanation:

The length of the diagonal of a rectangle is \sqrt{181} inches.

Compute the value of \sqrt{181} inches as follows:

The number 181 is not a square of a whole number.

So, the square root of 181 must lie between two whole numbers.

Consider the following squares:

12^{2}=144

13^{2}=169

14^{2}=196

It is quite clear that the 181 lies between the square of 13 and 14.

So, it can be said that the square root of 181 is between the square of 13 and 14.

Thus, the length of the diagonal of a rectangle is between 13 and 14 inches.

The correct option is (B).
