The whole field is square, and its total area is 25 acres. 
It's divided up into 25 little sections. 
Each little section is a square, and its area is 1 acre. 

So the whole thing looks like a square tray with 25 little square blocks in it.
The blocks are in 5 rows, and there are 5 blocks in each row.

There are 16 blocks around the edge of the square tray, and 9 in the middle
that don't touch the edge.

Every block costs $1,200 to start out.  But the ones around the edge are
more expensive.  Anything on the edge costs an extra $150 for each side
of the little block that touches the edge.

Most of the 16 little blocks around the outside have only 1 side that touches
the edge.  But the ones in the <em>corners</em> of the tray have 2 sides along the edge.

You may want to have a look at the picture I attached.

That should be plenty to put you in a position to work out the costs.

A line passing (a,3) and (5,5) is perpendicular to a line passing through (0,0) and (1,a) Find the value of a.
vodka [1.7K]

Answer:

a = -5

Step-by-step explanation:

(5 - 3)/(5 - a)

2/(5 - a)

perpendicular of 2/(5 - a) = -(5 - a)/2

(a - 0)/(1 - 0) = -(5 - a)/2

a/1 = -(5 - a)/2

2a = -5 + a

a = -5

Step-by-step explanation:

<u>Step 1: Define</u>

<em>Identify</em>

Point (7, 0)

Equation y = x - 7

<u>Step 2: Find</u>

  1. Substitute in point [Equation]:                                                                         0 = 7 - 7
  2. Subtract:                                                                                                            0 = 0

Since 0 = 0 is true, then it would be a solution to the equation.
