Length of a circle=2πr
r=40 m
Length of the circular track=2*π*40m=80π m.
The athelete jogs each day 10 laps
1 lap-------------------80π m
10 laps------------- x
x=(10 laps * 80π m) / 1 lap=800π m
Calculate how far he jog eache week (5 days).
1 day------------------800π m
5 days---------------- x
x=(5 days*800π m)/1day=4000π m=4000m * 3.141592...≈12566,37 m
solution: 12566 m
Answer:7
Step-by-step explanation:
Simplifying, 6x-2x-8 = 6 + 2x
4x -8 = 6 + 2x
2x =14
x=7
You're given a table of x values and an equation. To solve, plug in the values for x.
First box: y=2(-3)-1=-7
Second box: y=2(-2)-1=-5.
See if you can solve the third one.
Events are mutually exclusive only if they cannot both be true.
Only C is alright.
4 is a multiple of two so it can't be right.
Same logic works for B.
And then 2 is prime so then D is out too.
