In a work division of 45 employees 20 or male 30 of the employees are at least 40 years old and six of the females are less than 40 years of age referring to the above information how many males are at least 40 years of age

 The correct option is (d).

Step-by-step explanation:  Given that Jamaal spent x minutes today practicing his guitar and y minutes today on homework.

We are to select the inequality that best represents his practice time if the total time he spent on both is 45 minutes or more.

Since Jamaal spent 'x' min practicing guitar and 'y' min on homework, so the total time spent by him on both will be

Since he can spend 45 minutes or more on both, so (x+y) will be either greater than or equal to 45.

Therefore, the inequality that best represents his practice time is

Thus, the required inequality is

Option (d) is correct.
