If Car A is moving 10 m/s east and Car B is moving 15 m/s west.

Car A is moving at a speed of 25 m/s east relative to Car B.

Let O denote an observer. Then

v_{A/B}=v_{A/O}+v_{O/B}=v_{A/O}-v_{B/O}

where v_{X/Y} denotes the velocity of a body X relative to another body Y. We're told that

v_{A/O}=10\dfrac{\rm m}{\rm s}

and

v_{B/O}=-15\dfrac{\rm m}{\rm s}

where we take east to be to the positive direction. Then

v_{A/B}=(10-(-15))\dfrac{\rm m}{\rm s}=25\dfrac{\rm m}{\rm s}

What percent of students ran the mile in 12 minutes or less?
otez555 [7]
41% of students ran in 12 minutes or less.

Using the histogram we see that there were 2+12+11+9=34 students that ran.  Out of those, 2+12=14 ran in 12 minutes or less (the first two bars).

14/34 = 0.411 = 41%.

Explain to me in words how you would find the slope of this line and explain answer
Andrews [41]
Answer:
7/3

Explanation:
The slope of the line is equal to the rise/run, or in other words, the number of units the line travels upwards over the number of units the line travels to the right.

We can identify the slope using any two points on the line. Here, we can use the two points that are marked on the picture. The second point is 7 units above the first and 3 units to the right of the first, so the slope of the line is equal to 7/3.

Another way to calculate the slope of the line is the use this formula:

(y2-y1)/(x2-x1)

The first point is at the coordinate (1,-4) and second point is at the coordinate (4,3). When we plug these two coordinates into the equation, we get this:

(y2-y1)/(x2-x1)
->(3-(-4))/(4-1)

When we simply the fraction, we would get 7/3 and that would give us the slope.
