Answer: the length of the field is 70 yards. The width of the field is 35 yards

Step-by-step explanation:

Let L represent the length of the rectangular athletic field.

Let W represent the width of the rectangular athletic field.

A rectangular athletic field is twice as long as it is wide. This means that

L = 2W

The formula for determining the perimeter of a rectangle is expressed as

Perimeter = 2(L + W)

If the perimeter of the athletic field is 210 yards, it means that

210 = 2(L + W)

L + W = 210/2 = 105

Substituting L = 2W into L + W = 105, it becomes

2W + W = 105

3W = 105

W = 105/3 = 35

L = 2W = 2 × 35

L = 70

The president of a certain university receives a salary that is three times the salary of one of the department heads. The total
marissa [1.9K]

Answer:

Salary of President =   $180,000

Salary of Dept. Head =  $60,000

Step-by-step explanation:

The question is to find the salary of president and department head.

We let the salary of one of department heads be "x"

Since, the salary of president is THREE (3) TIMES a department head, we can say:

Salary of President = 3x

Now, we know the total of these 2 salaries is 240,000. Thus, we can write:

Salary of President + Salary of Dept. Head = 240,000

3x + x = 240,000

Now, we can solve for x:

3x + x = 240,000\\4x=240,000\\x=60,000

And now the president is "3x", so his salary is:

3(60,000) = 180,000

Thus,

President's salary = 180,000

Dept head's salary = 60,000
