It will take 0.556 seconds for an echo to reach one's ears
<h3>Calculating the time to hear an echo</h3>
From the question, we are to determine how long it would take an echo to reach one's ears
From the formula,
NOTE: To hear an echo, the sound will travel to and fro, hence, it will cover twice the distance
From the given information,
Distance = 92.0 m
NOTE: Speed of sound in air at 0 °C ≅ 331 m/s
Putting the parameters into the formula, we get
Time = 0.556 secs
Hence, it will take 0.556 seconds for an echo to reach one's ears.

Answer:
17
Step-by-step explanation:
2*6=12
20/4=5
12+5=17
PEMDAS
I agree that the y seemingly abe’s is connected to fry nye
So you have s=(w-10e)/5
To get rid of the 5, multiply the equation by 5, then to the other side.
So now it is 5s=w-10e
Now subtract w. So its now 5s-w=-10e
Now divide the -10. So now it is e=(5s-w)/-10
And it will not simplify because the s and w have different coefficients.
The total perimeter of the chicken coop if the length of one side is 3√5 yards is; 15√5 yards.yards
<h3>How to calculate the total perimeter?</h3>
We are told that Isabelle had a five sided chicken coop in her yard and that the length was equal in all the sides.
Now, we need to find the total perimeter of the chicken coop.
The length of one side of the coop from online sources is 3√5 yards.
Since the coop is 5 sided, it means that it is a pentagon and we know that;
Perimeter of a pentagon = 5a
Where a is length of one side of the pentagon. Thus;
Perimeter = 5 x 3√5
Perimeter = 15 √5 yards
