To describe three real life quantities that varies jointly with each other.
Answer to Problem 51HP
The three real life quantities that varies jointly with each other are as follows:
1. Distance travelled variation with average speed and time is an example of real life quantities that varies jointly. In this case distance travelled is equals to the product of average speed and time.
2. Annual simple interest variation with principal and rate of interest is also an example of real life quantities that varies jointly. In this case annual simple interest is equals to the product of principal amount and rate of interest divided by 100.
3. Total space acquired in a disc variation with size of each file and number of files is also an example of real life quantities that varies jointly. . In this case total space acquired in a disc is equals to the product of size of each file and number of files.
Explanation of Solution
Given information:
The given statement is that describe three real life quantities that varies jointly with each other.
The three real life quantities that varies jointly with each other are as follows:
1. Distance travelled variation with average speed and time is an example of real life quantities that varies jointly. In this case distance travelled is equals to the product of average speed and time.
2. Annual simple interest variation with principal and rate of interest is also an example of real life quantities that varies jointly. In this case annual simple interest is equals to the product of principal amount and rate of interest divided by 100.
3. Total space acquired in a disc variation with size of each file and number of files is also an example of real life quantities that varies jointly. . In this case total space acquired in a disc is equals to the product of size of each file and number of files.
