Answer:
1995 => 22°
2005 => 36°
Step-by-step explanation:
Central angle of the sector representing nuclear energy in 1995 = percentage of nuclear energy in 1995 ÷ 100 × 360°
Nuclear energy is approximately 6% (rounded to whole number) in 1995.
Central angle = 

Central angle representing nuclear energy in 1995 ≈ 22° (nearest whole number).
Central angle of the sector representing nuclear energy in 2005 = percentage of nuclear energy in 2005 ÷ 100 × 360°
Nuclear energy is approximately 10% (rounded to whole number) in 1995.
Central angle = 

Central angle representing nuclear energy in 2005 = 36°.
Answer: 4x+8
Step-by-step explanation:
Okay since the area for the block is X, two numbers multiplied together is X.
Since the big block has an area of X^2, then this shows the sides to be X.
This gives the sides of the block with area X to be 1 and X.
Now just add up every side like this : 1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 + x + x + x + x to get 4x+8
Answer:
A: there is not enough information because there are no numbers to incorporate the sizes on it so that would mean that there is <u><em>not enough information!!!</em></u>
