Answer:

The elevation of Lucas Oil Field is of 715 feet.

Step-by-step explanation:

Elevation of Sports Authority Field:

Of 5280 ft.

Compared to Lucas Oil Field:

275ft than seven times the Lucas Oil Field elevation of x.

Equation:

$275 + 7x = 5280$

What is the elevation of Lucas Oil Field?

Solving the above equation:

$7x = 5280 - 275$

$7x = 5005$

$x = \frac{5005}{7}$

$x = 715$

The elevation of Lucas Oil Field is of 715 feet.

Answer:

The percentage error of measurement is 5.63 %

Step-by-step explanation:

Given as :

The measure length of the fence = 150 feet

The actual length of the fence = 142 feet

Let the percentage error in measurement = x

So, x = $\dfrac{\textrm measured value - \textrm actual value}{\textrm actual value}$ ×100

Or, x = $\dfrac{\textrm 150 - 142}{142}$ ×100

or, x = $\dfrac{\textrm 8}{142}$ ×100

or, x = 5.63 %

Hence The percentage error of measurement is 5.63 % Answer
