Find the area of the plot of land:
40 x 40 = 1600 square meters.
Now divide total area by parts:
1600 / 64 = 25 square meters.
Answer: 25 square meters
Answer: No, it is not a right triangle.
Explanation:
9^2 + 7^2 (?) 12^2
81 + 49 (?) 144
130 = 144
Since 12^2 = 144, and the square root of 130 is 11.4^2, it is not a right triangle.
A beam of light (travelling at the speed of light) would take 65 years to go and 65 years to come back from aldebaran, i.e. 130 years. You can send and receive a radio message (travelling at the speed of light, being electromagnetic radiation) taking so 130 years.
Answer: A Person's age is usually considered a discrete variable.
Step-by-step explanation: lets say a person was born in November 2000 and the date is currently September 2020 if asked their age the person would say 19 because they have not turned 20 yet. therefore no matter what date anytime between their 19th birthday up until their 20th birthday they would say they are 19 making age a discrete variable.
