Answer

Question 18

From the graph, sum up the percentages of energy consumed by residential and commercial sectors.

By visual - inspection, the combined percentage of energy consumed by residential and commercial sectors is approximately 37%.

Answer:

b) 37%

Answer:

b) No. Claudia will not be able to roll her tongue because neither of her parents can roll their tongues.
