Accepted Answer

### Part (a)
# Brief Explanations:
A pie chart is suitable when the data represents parts of a whole. For U.S. primary energy consumption, different energy sources (like geothermal, nuclear, etc.) contribute to the total energy consumption, so they are parts of the whole total energy. Option C correctly states this.
# Answer:
C. The data make up parts of a whole.

### Part (b)
(Note: Since the graphic is not visible, we assume typical U.S. energy consumption data. In 2020, geothermal energy consumption in the U.S. was about 0.4% of total primary energy consumption. But if we had the graphic, we would:
## Step1: Identify total energy and geothermal energy
Let total energy be $ T $ and geothermal energy be $ G $.
## Step2: Calculate percentage
Percentage $ = \frac{G}{T} \times 100 $
)
Assuming from standard data, geothermal is about 0.40% (rounded to two decimals). But with the actual graphic, we'd use the values from it. For example, if total energy is $ T $ quadrillion Btu and geothermal is $ G $ quadrillion Btu, then $ \text{Percentage} = \frac{G}{T} \times 100 $.
# Answer:
0.40 (or the value from the graphic, e.g., if graphic shows geothermal as 0.4% then 0.40)

### Part (c)
(Note: Typical 2020 U.S. nuclear electric power consumption was about 8.25 quadrillion Btu. With the graphic:
## Step1: Find total energy and nuclear's percentage
Let total energy be $ T $ and nuclear's percentage be $ p $.
## Step2: Calculate nuclear energy
Nuclear energy $ = T \times \frac{p}{100} $
)
Assuming total energy (from 2020 data) is about 100 quadrillion Btu (approximate total primary energy), and nuclear is 8.25% (from standard data), then $ 100 \times \frac{8.25}{100} = 8.25 $ quadrillion Btu. With the graphic, use total energy $ T $ and nuclear's percentage $ p $ to compute $ T \times \frac{p}{100} $.
# Answer:
8.25 (or value from graphic, e.g., if total is $ T $ and nuclear % is $ p $, then $ T \times \frac{p}{100} $)

### Part (d)
(Note: Typical 2020 U.S. geothermal consumption was about 0.4 quadrillion Btu. With the graphic:
## Step1: Find total energy and geothermal's percentage
Let total energy be $ T $ and geothermal's percentage be $ p $.
## Step2: Calculate geothermal energy
Geothermal energy $ = T \times \frac{p}{100} $
)
Assuming total energy $ T = 100 $ quadrillion Btu (approximate) and geothermal % is 0.4%, then $ 100 \times \frac{0.4}{100} = 0.4 $ quadrillion Btu. With the graphic, use $ T $ and geothermal % $ p $ to compute $ T \times \frac{p}{100} $.
# Answer:
0.40 (or value from graphic, e.g., if total is $ T $ and geothermal % is $ p $, then $ T \times \frac{p}{100} $)
