Max has a rectangular plot that is 63 square meters in area. he keeps his 7 goats, his 18 chickens and his brown and white horse in the plot which is enclosed on all four sides by a white picket fence. the length of the plot is 9 meters. so the total length of the white picket fence is

The total length of the white picket fence is 32 m.

Step-by-step explanation:

Length of plot = 9 m

Let the breadth of the plot be x

So, Area of Plot =

                         =

We are given that Area of rectangular plot is 63 sq.m.

So,

All four sides are enclosed by a white picket fence.

Perimeter of plot =

                            =

                            =

So, the total length of the white picket fence is 32 m.

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth

step-by-step explanation:

answer: a video game has three difficulty levels: easy, medium, and expert. the game's scoring works in such a way that a player has to score a fixed number of points to advance to the next level, and then the scoring starts over. the total score needed to clear all three difficulty levels is 7,500. two times the number of points needed to clear the easy level is 500 more than the number of points needed to clear the medium level. twice the number of points needed to clear the medium difficulty level is 1,500 more than the number of points needed to clear the expert level. if x, y, and z represent the easy, medium, and expert levels, respectively, and a is the coefficient matrix of the system of equations modeling this situation, identify the inverse matrix, a-1, and the solution matrix, x, of the system of equations.
