Worked Solution & Example Answer:The table below shows the percentages of all the different types of energy sources used in each of 13 European countries during 2014 - Leaving Cert Mathematics - Question b - 2020

Step 1

What percentage of the energy used in Denmark in 2014 was renewable?

96%

114 rated

Answer

To find the percentage of renewable energy used in Denmark, we take the renewable percentage, which is 31%.

Thus, the answer is: 31%.

Step 2

Name the four countries that used a lower percentage of renewable energy than Ireland.

99%

104 rated

Answer

The four countries that used a lower percentage of renewable energy than Ireland (6%) are:

  1. Cyprus
  2. Luxembourg
  3. Malta
  4. Bulgaria

Step 3

Name a country which did not use gas as a fuel source.

Answer

A country that did not use gas as a fuel source is Cyprus.

Step 4

Complete the table to show the angle for each energy type.

98%

120 rated

Answer

To find the angles for each energy type, we use the formula:

ext{Angle} = rac{ ext{Percentage}}{100} imes 360

  1. Oil: rac{42}{100} imes 360 = 151.2° ightarrow 151°
  2. Solid Fuel: rac{13}{100} imes 360 = 46.8° ightarrow 47°
  3. Gas: rac{24}{100} imes 360 = 86.4° ightarrow 86°
  4. Electricity: rac{15}{100} imes 360 = 54°

Final table:

TypePercentageAngle
Renewable622°
Oil42151°
Solid Fuel1347°
Gas2486°
Electricity1554°

Step 5

Complete the pie chart below to show the energy types used in Ireland in 2014.

Answer

The completed pie chart will include the following labeled sections:

  • Renewable: 22°
  • Oil: 151°
  • Solid Fuel: 47°
  • Gas: 86°
  • Electricity: 54°

Make sure to label each section clearly on the pie chart.
