Hello!
First of all, we can subtract the stretching time. This gives us 20. If we divide by the four laps we get 5 minutes per lap.
Now, one lap is 400 meters (most tracks are), which is equal to 15,748.03 inches. This means it takes her five minutes to walk 15,748.03 inches. This is also equal to 300 seconds, so it takes her 300 minutes per 15,748.03 inches.
But if we round our big inches number to the nearest ten thousandth, we get 16,000, so in a simpler form her pace is 300/16,000. But we need to find in per second. Therefore we will divide by 300 to find how many inches she walks per second. This means she walks about 53.33 inches per second.
I hope this helps!
Answer:
C) 20 hours
Step-by-step explanation:
x = number of hours
A yard cleanup service charges a $380 fee plus $14 per hour.
380 + 14x
Another cleanup service charges a $260 fee plus $20 per hour.
260 + 20x
How long is a job for which the two companies' costs are the same?
380 + 14x = 260 + 20x
380 - 260 = 20x - 14x
120 = 6x
20 = x
Simply put 10 in all of the boxes. There are 5 boxes. And all those boxes equal 50, right? So for every box, there's 10 students. 10 multiplied by 5 is equal to 50.
The answer would be the the top right choice. an outlier is a point that falls outside the data and that choice is the correct one.
