Nikki notice she needed 1/10 of a can of paint to paint one wall. The second wall needed 8/9 of a can of paint. How much paint was used to cover the walls?

i just need points

Step-by-step explanation:

Step-by-step explanation:

- Dynamic flexibility tests involves measure the amount of stress on a muscle that is in motion.

- Static flexibility tests involves measure the amount of stress on a muscle that is stationary.

- Dynamic study is subjected to infinitely many solutions with singularities ( Points where solutions may not exist ) or entail paradoxes. This makes Dynamic study both hard and subjective to measurements. Usually an experimental techniques are adopted with data acquisition systems.

- Despite the subjectivity of dynamic study to measurements and more prone to experimental errors it provides a closest approximations to realistic situations.

- Since, many solutions exist for dynamic flexibility tests with uncertainties and singularities it is rather difficult to standardized the results; however, numerical approximations and empirical results are developed for different conditions.
