Answer:
4.333 meters
Step-by-step explanation:
Given:
We are told that the rope is cut into two pieces and that one (longer) piece is twice the length of the other (short) piece
let the length of the short piece = x meters
hence the length of the longer piece = 2x meters
we are also given that the total length of the two pieces is 6.5m
hence,
length of short piece + length of long piece = 6.5 m
in equation form:
x + 2x = 6.5
3x = 6.5 (divide both sides by 3)
x = 6.5/3 meters
we are asked to find the length of the long piece (i.e 2x)
hence
2x = 2 (6.5/3) = 4.333 meters (answer)
Answer:
V = 15/4π = 3.75π
Step-by-step explanation:
V=πr^2h
V=π(1/2^2)15
V=π(1/4)15
V=15/4π
It is a ray. Which is a... please thank me
8(4x+5)=136
Multiply the number outside of the parenthesis(8) with the numbers inside the parenthesis(4x and 5).
32x+40=136
Subtract 40 from both sides
32x=96
Divide both sides by 32 so the only thing remaining on the side of the variable is only the variable itself.
Final Answer: x= 3
