The water level in Rocky's lake changes on an average of -7/16 every 3 years. Based on the rate of the level, how much will the water level change after a year

-7/ 48

Step-by-step explanation:

Given that:

Average change in water level per 3 years = - 7/16

This means the water level decreases by - 7/16 on average every 3 years

The change in water level after a year will be ;

-7/16 = 3

x = 1

Cross multiply ;

3x = - 7/16

Divide both sides by 3

x = -7/16 ÷ 3

x = - 7/16 * 1/3

x = - 7 / 48

Hence, water level will change by - 7/48 after a year.

not only in mathematics, scientific proof also are required in the other field of science. also maths proofs are of particular structure, containing steps and logics. so proving is like doing science, it is science. that's why it is important to prove. 

an inaccurate proof leads to errors, or stating results that are not accurate.  which wil mess the probelm up you dont want this
