Answer:
a)
Thus, there are 22 minutes per lap
b)
Thus, there are 0.5 laps per minute
c)
If Lin runs 21 laps at the same rate, it would take 42 minutes to do so.
Step-by-step explanation:
Lin runs 5 laps around a track in 10 minutes.
i.e. 5 laps in 10 minutes.
so
5/10 = 1/2 laps per minute
- unit rate = 0.5 laps / per minute
a)
Thus, there are 22 minutes per lap
b)
Thus, there are 0.5 laps per minute
c)
Unit rate = 0.5 laps per minute
If Lin runs 21 laps at the same rate, it would take 42 minutes to do so.
Answer:
$420
Step-by-step explanation:
130x12=1560
165x12=1980
1980-1560=420
There is 360 degrees in a full revolution.
There are 7 sides/edges/vertices in a heptagon.
360/7 = 51.42857143
The degree of an angle in a regular heptagon is thus 51.42857143 degrees.
The sample space would be the number of students, so 1200.
The outcome the compose the event would be drawing one name at random.
The probability of Sophia winning would be 1 out of 1200, as a fraction: 1/1200, as a decimal: 0.00083
Because there is 1200 students, the probablity would be unlikely, since the sample is a large number.
Unfortunately, there is no given table. However, assuming no air resistance, the projectile moves in constant acceleration in the y-axis, while constant velocity in the x-axis. If the total time of flight is 6 seconds, then at 3 seconds the reaches its maximum height. Also, there is no given initial velocity, which means any useful calculation is impossible.
