Calculate the perimeter of a rectangle which is 11 metres long and 4 metres wide
mote1985 [20]
To calculate the perimeter of a rectangle what you would do is add the parallel sides together so 11+11=22 and then 4+4=8 so we would add 22+8=30

So your answer would be 30

The graph shows the feasible region for the system with constraints:
Dimas [21]

Answer:

The vertices feasible region are (0 , 15) , (10 , 15) , (20 , 5)

The minimum value of the objective function C is 125

Step-by-step explanation:

* Lets look to the graph to answer the question

- There are 3 inequalities

# y ≤ 15 represented by horizontal line (purple line) and cut the

  y-axis at point (0 , 15)

# x + y ≤ 25 represented by a line (green line) and intersected the

  x-axis at point (25 , 0) and the y- axis at point (0 , 25)

# x + 2y ≥ 30 represented by a line (blue line) and intersected the

  x-axis at point (30 , 0) and the y-axis at point (0 , 15)

- The three lines intersect each other in three points

# The blue and purple lines intersected in point (0 , 15)

# The green and the purple lines intersected in point (10 , 15)

# The green and the blue lines intersected in point (20 , 5)

- The three lines bounded the feasible region

∴ The vertices feasible region are (0 , 15) , (10 , 15) , (20 , 5)

- To find the minimum value of the objective function C = 4x + 9y,

  substitute the three vertices of the feasible region in C and chose

  the least answer

∵ C = 4x + 9y

- Use point (0 , 15)

∴ C = 4(0) + 9(15) = 0 + 135 = 135

- Use point (10 , 15)

∴ C = 4(10) + 9(15) = 40 + 135 = 175

- Use point (20 , 5)

∴ C = 4(40) + 9(5) = 80 + 45 = 125

- From all answers the least value is 125

∴ The minimum value of the objective function C is 125

HELP! NEED DONE IN 24 MIN.
Gala2k [10]

Answer:

37.8

Step-by-step explanation:

Set up a proportion using the values given in the diagram of similar triangles.

31.5/15 = x/18

Cross-multiply.

31.5(18) = 15x

Multiply.

567 = 15x

Divide both sides by 15.

37.8 = x

Estimate the difference. 9 1/2- 1 6/7
Sav [38]

Answer:

= 7 \frac{9}{14}  \\

Step-by-step explanation:

9 \frac{1}{2}  - 1 \frac{6}{7}  \\   \frac{19}{2}  -  \frac{13}{7}  \\  \frac{133 - 26}{14}  \\  =  \frac{107}{14}  \\  = 7 \frac{9}{14}

hope this helps

brainliest appreciated

good luck! have a nice day!
