4 0

Answer:

  y = 4/3

Step-by-step explanation:

The two equations can be added to eliminate x:

  (0.1x +0.5y) + (-0.1x -0.2y) + (1.2) +(-0.8)

  0.3y = 0.4 . . . . . simplify

Divide by the coefficient of y to find y:

  y = 0.4/0.3

  y = 4/3

For the following problem state the objective function and the constraints. DO NOT solve:
Mama L [17]

Answer:

If we define S as the number Sprinkle's umbrellas, and H as the Hurricane's umbrellas, the profit P can be expressed as:

P=3S+5H

The restriction for cloth can be written as:

S+2H\leq500

The restriction for metal can be written as:

2S+3H\leq600

The restriction for wood can be written as:

4S+7H\leq800

The condition for S and H to be positive is:

S, H \geq0

Step-by-step explanation:

We have an objective function that, in this case, we want ot maximize.

This function is the Profit (P).

If we define S as the number Sprinkle's umbrellas, and H as the Hurricane's umbrellas, the profit can be expressed as:

P=3S+5H

We have 3 restrictions, plus the condition that both S and H are positive.

The restriction for cloth can be written as:

S+2H\leq500

The restriction for metal can be written as:

2S+3H\leq600

The restriction for wood can be written as:

4S+7H\leq800

The condition for S and H to be positive is:

S, H \geq0

All you need to do is solve it
\frac{1}{2} ^{2} or \frac{1}{2}  x \frac{1}{2}
When solved your answer is 0.25 or 1/4
------------------------
What I did to solve it was....

1. Divide top fraction by bottom fraction to get decimal
1 ÷ 2 = 0.5

2. Then multiply 0.5 by its self (the same as putting it to the ^2)
0.5 x 0.5 = 0.25
