Answer: 60 in
Step-by-step explanation:
Hi, to answer this question, first we have to calculate the diameter of one flotation device:
Circumference of a circle C = (3.14) (diameter)
Replacing with the values given:
62.8 =3.14 d
Solving for d (diameter)
62.8 /3.14 =d
20in = d
Now, since the three flotation devices are identical, we simply have to multiply the diameter of one device by 3 , to obtain length of the flotation devices lined up.
20x3 =60 in
Feel free to ask for more if needed or if you did not understand something.

it shows two points for each x, meaning its not a function.
Answer: 271.
Step-by-step explanation:
When the prior population proportion of success is not available, then the formula to find the sample size is given by :-
Given : Significance level : 
By using the standard normal distribution table ,
Critical value : 
Margin of error : 
Then , the required minimum sample size will be :-
Hence, the required minimum sample size is 271.
To get your answer you need to get the average the plane goes and then multiply it by 35 hours. hope this helps:)
Answer:
Length = 24 and width = 6.
Step-by-step explanation:
2L + 2W = 60 where L = length and W = width.
The length must be in the 20's to make a perimeter of 60, as there's no number in the 10's or 30's that has 2 consecutive even integers and 40 something is impossible.
The only length which fits the given conditions is 24.
Then the width would be (60 - 2(24)) / 2 = (60 - 48) / 2
= 6.
That's the answer.
