if a 25 ft rope is cut into two sections with one section four times as long as the other section, how long is the shorter piece
2 answers:
Total length of rope = 25 feet
Let us say one part of the rope is x, then the other part will be 25-x.
We are given that one section of the rope is four times as long as the other.
So let us make an equation using this information,
x=20
So one part is 20 feet and the second part is 25-20= 5 feet.
Answer: The shorter part of the rope is 5 feet long.

<h2>$3448.81</h2>Step-by-step explanation:
Using the compound interest formula to calculate the amount compounded after 10years.
P = principal = $2000
r = rate (in %) = 5.6%
t = time (in years) = 10years
n = 1year = time used in compounding
Amount compounded after 10 years is $3448.81
Answer with Step-by-step explanation:
We are given that
We have to explain that why the function is discontinuous at x=2
We know that if function is continuous at x=a then LHL=RHL=f(a).
LHL=Left hand limit when x <2
Substitute x=2-h
where h is small positive value >0
Right hand limit =RHL when x> 2
Substitute
x=2+h
LHL=RHL=
f(2)=1
Hence, function is discontinuous at x=2
The length of the fencing corresponds to the length of the perimeter of the garden:
We also know that the perimeter of a circle is given by:
where r is the radius of the circle.
Putting together the two equations, we have
from which we can find r, the radius of the garden:
