Jenny won the race as she finished the race much more quickly and has greater average speed than Lester.

\sf \boxed{\sf speed:\frac{distance}{time \ taken} }

Jenny: distance/time = 100/15.2 = 6.58 m/s = 6.6 m/s

Lester: distance/time = 100/15.7 = 6.37 m/s = 6.4 m/s

What is the angle of rotation of the minute hand of a clock moving from 6:10 to 7:00?
igomit [66]
Because the movement of the minute han of a clock is clockwise ↓, then the angle of rotation will be negative.

1) we calculate the number of minutes from 6:10 to 7:00

number of minutes=7:00-6:10=6:60 - 6:10=50 minutes.

2)
We know that:
60 minutes of a clock have turned -360º
Then:

60 minutes of a clock------------------------- -360º
50 minutes of a clock-------------------------      x

x=(50 minutes of a clock * (-360º))/60 minutes of a clock=-300º


Answer:  A. -300º

Find the slope of the line that passes through the points (0, -3) and (-4,1).
kozerog [31]

The formula for slope is \frac{y_{2} -y_{1} }{x_{2} -x_{1} }

In this case:

y_{2} = 1\\ y_{1} }= -3\\x_{2} = -4\\x_{1} = 0

so...

\frac{1 - (-3)}{-4 - 0}

\frac{4}{-4}

-1 <<<The slope

Hope this helped!
