8x + 30=110
110-30=80/8=10
Your answer is x = 10
1) linear <span>III. y=2x+1
2) x-int, </span><span>y=3x+5, y=0, 0=3x+5, 3x=-5, x=-5/3
</span><span> B.) (-5/3,0)
3)
</span><span>maybe question was : What is not a function?
I. x^2+y^2=1 not function
II. y=x^2 function
III. y=4x-10 function
IV. 1/2y=3x function</span>
Answer: the length of the needle is 8.49 inches.
Step-by-step explanation:
The diagram of the clear cube is shown in the attached photo. From the diagram, a right angle triangle ABC is formed.
BC represents the diagonal of a face of the cube.
AB represents the the side length of the clear cube.
AB = h represents the length of the needle
To determine AB, we would apply Pythagoras theorem which is expressed as
Hypotenuse² = opposite side² + adjacent side²
Therefore
AB² = 6² + 6² = 72
AB = √72
AB = 8.49
