Yeah,I'm sure you have it right. ;)
The number to which a base is raised to is called the _exponent_ This tells you how many times to multiply the base together.
Answer:
carbon footprint
7.7 tons
Step-by-step explanation:
Given that,
carbon dioxide produced by a car over 7 year period = 53.5 tons
To find,
carbon footprint <em>(tons of carbon dioxide per year)</em>
7 years ------> 53.5 tons
1 year -------> 53.9/7 tons
= 7.7 tons
tons of carbon dioxide produced per year = 7.7
4/5 is a fraction equivalent to 32/40. This is in simplest form.
Another fraction that is equivalent to 32/40 is 16/20.
