your answer is 5 bc you want to rearrange the numbers like this (5i - 5i) - (3 -(-2)) so (5i - 5i)= 0 and 3 - (-2) is 5

2 divided by 1 and 6/7

ale4655 [162]

This problem, as written, requires a bit of guessing regarding your intentions. My interpretation is that you want to do this division:

----------

1 6/7

If that's correct, here's what to do: rewrite 1 6/7 as 13/7 (an improper fraction).

Then divide:

-------- This is equivalent to the multiplication (2/1)(7/13) = 14/13 (answer)

13/7

the boundary of a rectangular farm field in ireland has a straight rock wall along one side and fences along its other three sid

Inessa [10]

Answer:

781250 $ft^{2}$

Step-by-step explanation:

Let y is the length of the farm field

Let x is the width of the farm field

Given that, no fencing is necessary along the rock wall, so we can find the perimeter of the farm is:

2x + y = 2500 feet

<=> y = 2500 -2x

The are of the farm has the following formula:

A = x*y

<=> A = x(2500 - 2x)

<=> A = 2500x -2 $x^{2}$

To have the maximum area of field in square feet, we need to use differentials to estimate:

$\frac{dA}{dx}$ = 2500 - 4x

Set $\frac{dA}{dx}$ = 0, we have:

2500 - 4x = 0

<=> x = 625 feet.

=> y = 2500 - 2*625 = 1250 feet

So the maximum area of field is:

A = x*y = 625*1250 = 781250 $ft^{2}$
