106 because, 85 plus 21 = 106

The answer is 112 because the number in between keeps going up by three. I know that sounds confusing but here is my logic.

61-40=21 21+3=24 and 61+24=85 so this means that if we add 3 to 24, we will get 27 and if you add 27 to 85 you get 112. Then after that add 3 to 27 and get 30. Then add 30 to 112 and get 142.

So basically the answer is 112 because the number being added to the other numbers goes up by 3 every time. Hope that helped:)

I think you mean six-hundred and seventy six.

6 ÷ 576 = 0.010416

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 $ft^{2}$
