Answer:

Step-by-step explanation:
At least 6 hours means that the people took at least 6 hours and at most any number that is greater than 6. Here the greatest no. is 10.
<em><u>So, the range for this will be 6-10</u></em>
No. of People who sleep for 6-8 hours = 9
No. of People who sleep for 8-10 hours = 3
No. of People who sleep for 6-10 hours = 9+3
=> 12 people
20% of 58 = 11.60
so $11.60 is the answer
Answer:
L = 12
W = 20
Step-by-step explanation:
The perimeter of the rectangle is 64.
2L + 2W = 64
The length and width of a rectangle are in a 3:5 ratio.
3 + 5 = 8
64/8 = 8
2L = 8 * 3 = 24
L = 24/2 = 12
2W = 8 * 5 = 40
W = 40/2 = 20
