Mary put new tiles on her kitchen floor. The floor measures 6 feet long by 5 feet wide. she used 10 tiles to cover the entire fl
balu736 [363]

Answer:

30 square feet

Step-by-step explanation:

Number of tiles used for covering the kitchen floor = 10

Area covered by the floor = 6 * 5 feet^2                                                

                                        = 30 square feet

Length of each tiles = 3 feet

Width of each tiles = w feet

Area covered by each tiles = 3w square feet

Then the equation can be written as

3w * 10 = 30

30w = 30

w= 30/30      

   = 1 feet

10 *3w = 30

Find the minimum value of the function for the polygonal convex set determined by the given system of inequalities.
lutik1710 [3]

Answer:

Option b (4,1)

Step-by-step explanation:

The region given by the system of inequalities is shown in the graph. We must look within this region for the point that minimizes the objective function f(x, y) = 8x + 8y

The minimum points are found in the lower vertices of the region.

These vertices are found by equating the equations of the lines::

3x+2y=14\\-5x +5y=10

-------------------

x = 2\\y = 4

-8x + 3y = -29\\3x + 2y = 14

---------------------

x = 4\\y = 1

The lower vertices are:

(4, 1) (2, 4)

Now we substitute both points in the objective function to see which of them we get the lowest value of f(x, y)

f(4, 1) = 8(4) +8(1) = 40\\f(2, 4) = 8(2) + 8(4) = 48

Then the value that minimizes f(x, y) is (4,1).

Option b
