Answer:
About 70 to 80%
Step-by-step explanation:
About 70 to 80% of the world total volcanoes occur along the fire ring, The ring of fire is present near the pacific ocean the countries like Chile ,Japan and the island which are present near the pacific ocean are come under the fire ring , the ring of fire is very active in nature this is the reason most of the volcanoes and earthquakes occur here
Let
x---------> the length of the first piece
y---------> the length of the second piece
z---------> the length of the third piece
we know that
x+y+z=72 -------> equation 1
y=x+6 -----> solve for x
x=y-6 -------> equation 2
z=6+y -------> equation 3
substitute equation 2 and equation 3 in equation 1
[y-6]+y+[6+y]=72
3y=72
y=(72/3)=24 in
<u>Find the value of x</u>
x=y-6 -------> equation 2
x=24-6=18 in
<u>Find the value of z</u>
z=6+y -------> equation 3
z=6+24=30 in
therefore
<u>the answer is</u>
the length of the first piece is 18 in
the length of the second piece 24 in
the length of the third piece is 30 in
