Answer:

the total minutes taken together is 26.25 minutes

Step-by-step explanation:

The computation of the number of minutes that required to fill the tank together is shown below:

\frac{1}{45} + \frac{1}{63} = \frac{1}{x}\\\\\frac{7 + 5 }{315} = \frac{1}{x} \\\\\frac{12}{315} = \frac{1}{x} \\\\12x = 315\\x = 26.25minutes

Hence, the total minutes taken together is 26.25 minutes

The system of inequalities represents the given constraints will be x + y < 20 and 15x + 25y > 375.

<h3>What is inequality?</h3>

Inequality is defined as an equation that does not contain an equal sign. Inequality is a term that describes a statement's relative size and can be used to compare these two claims.

A nursing student works at a doctor's office for $15 per hour and tutors other students for $25 per hour.

Let x be the number of hours for the doctor's office and y be the number of hours for the tutor.

The student cannot work more than 20 hours each week.

      x + y < 20 ...1

15x + 25y > 375 ...2

The system of inequalities represents the given constraints will be x + y < 20 and 15x + 25y > 375.

\qquad \tt \rightarrow \: m \overbrace{DB}  + m \overbrace{TB}  = 180 \degree

[ linear pair ]

\qquad \tt \rightarrow \: m \overbrace{DB}  + 90 \degree  = 180 \degree

\qquad \tt \rightarrow \: m \overbrace{DB}    =  180 \degree    - 90 \degree

\qquad \tt \rightarrow \: m \overbrace{DB}    =   90 \degree
