Answer: 0.82 laps per minute
Step-by-step explanation:
Lin is running 21 laps in 25.6 minutes.
To find out her speed in laps per minute, divide the distance she has ran by the time it took her to run it.

= 21 / 25.6
= 0.82 laps per minute
Go to the google search engine.. take your little fingers and copy and paste this into it. The result will pop up within its calculator.
The area of the large box is x^2 and the area of the small box is 3^2 which is 9. So the area of the leftover part is x^2-9 or (x-3)(x+3).
Hope that helped.

B) 0.60n+1.48n = 176.80
Step-by-step explanation:
0.60 for every spiral wire per book = 0.60*n
0.74 per chipboard cover, 2 needed for each book = 1.48 per book = 1.48*n
Put it together: 0.60n+1.48n = 176.80

Control: No music
Step-by-step explanation:
A control group is the group that receives no changes in a experiment and is used as a benchmark. For example, a experiment where you wanted to know if plants can live without water, one of the treatments would be not giving them water. The control group would be the group that received water, like normal. Back to the question: Usually, music isn't played. Therefore no music would be the control group.
*Since you forgot to put the options, I can't be 100% sure, but I'm almost positive that this should be the answer.*
