What are the central angles of the sectors representing nuclear energy in both the years?( you may round the numbers before find
xeze [42]

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 = \frac{6}{100}*360 = \frac{6}{10}*36

= \frac{216}{10} = 21.6

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 = \frac{10}{100}*360 = \frac{1}{1}*36

= \frac{36} = 36

Central angle representing nuclear energy in 2005 = 36°.

Two cars are driving to the same place.
Dafna1 [17]

Answer:

The graph in the upper left  

Step-by-step explanation:

We can answer this question by elimination.

The answer can't be the two graphs on the right, because the two lines will never cross.

It can't be the graph at the lower left, because this shows both cyclists starting at Mile 0.

It must be the graph in the upper left. It shows one cyclist starting 45 mi ahead of the other, with the faster cyclist catching up after about 2.5 h.
