Total length of the pipe = 125 inches
Let the shorter piece be x inch.
Thus, the longer piece is 4x.
4x + x = 125
5x = 125
x = 25
Therefore, the lengths of the two pieces are 25 inches and 100 inches.
The value of p is -5
Simply use cross multiplication :
The process of multiplying numbers in the shape of a fraction is called cross multiplication. Cross multiplying, also known as cross multiplication, is the process of multiplying the numerator of one fraction by the denominator of the other fraction on the other side of an equal symbol. Cross multiplication is a method for comparing fractions.
Both fractions with like and unlike parts are multiplied across. When employing the cross-multiplication procedure, we multiply the denominators as well as the numerators when a fraction is dissimilar, or when the denominators of two fractions are not alike.

Answer:
n = 45°
Step-by-step explanation:
The sum of the exterior angles of an octagon is equal to 360°. Since there are 8 exterior angles, divide 360 by 8.
The cofunction of cos is sin(90-x)
90 degrees is equal to PI/2
The cofunction becomes sin(PI/2 - 2PI/9)
Rewrite both fractions to have a common denominator:
PI/2 = 9PI/18
2PI/9 = 4PI/18
Now you have sin(9PI/18 - 4PI/18)
Simplify:
Sin(5PI/18)
