Please help me now.....

Answers

Answer 1
Answer: -9= 2x-5

Add 5 to both sides

-4= 2x

Divide by 2

-2=x or x=-2

Answer:

  Look at the graph of the relationship. Find the y-value of the point that corresponds to x = 1. That value is the unit rate.

Step-by-step explanation:

The unit rate is the change in y for a 1-unit change in x. Since the graph of a proportion will go through the origin, it is appropriate to look at the y-value for x = 1 (one unit from the origin).

___

The ratio of units up to units to the right is also the unit rate when the fraction is reduced to lowest terms. It is a "unit" rate when the denominator of the fraction is 1 unit.

A company produces two products, A and B. The sales volume for A is at least 80% of the total sales of both A and B. However, the company cannot sell more than 110 units of A per day. Both products use one raw material, of which the maximum daily availability is 300 lb. The usage rates of the raw material are 2 lb per unit of A, and 4 lb per unit of B The profit units for A and B are $40 and $90, respectively. Determine the optimal product mix for the company

Answers

Answer:A=100 , b=25

Step-by-step explanation:

Let sales of A be x and sales of  B be y

Thus x\geq 0.8(x+y)

x\geq 4y

Also maximum A available is 110\geq x

300\geq 2x+4y

150\geq x+2y

We have find the optimal solution for

z=40x+90y

Optimal solution points

(100,25) z=40* 100+90* 25=6250

(110,20) z=40* 110+90* 20=6200

(110,0) z=40* 110+90* 0=4400

Thus for A=100 and B=25 Optimal solution is obtained

Final answer:

The optimal product mix problem involves maximizing profit given certain constraints. The constraints can be expressed in terms of inequalities which can be solved using linear programming techniques such as the corner point theorem or the simplex method.

Explanation:

The subject of this problem is to determine the optimal product mix of two products, A and B, produced by a company. This is guided by several constraints including sales volumes, maximum output, raw material availability, and profit units.

From the problem, we have two constraints. Firstly, sales of A must be at least 80% of the total sales of A and B, and no more than 110 units of A can be sold per day. Secondly, the company cannot use more than 300 lbs of the raw material per day with usage rates of 2 lbs per unit of A and 4 lbs per unit of B.

Let the quantity of A and B sold per day be x and y respectively. The profit is given by the expression 40x + 90y. We need to maximize this expression based on the constraints. The constraints can be expressed as follows:

  1. x ≥ 0.8(x + y), this is the sales volume constraint.
  2. x ≤ 110, this is the maximum sales constraint.
  3. 2x + 4y ≤ 300, this constraint arises from the raw material availability.

These constraints form a linear programming problem. By plotting these inequalities on a graph and finding the feasible region, we can use the corner point theorem or simplex method to find the optimal solution.

HOw far away can a person live from a radio station and hear its broadcast if the signal covers a circular area of 40000 square miles?

Answers

Answer:

The radio station is at the center of a circle with an area of 40,000 square miles.  The furthest point that you could hear the broadcast would be on the outer edge of the circle or at the end of the radius of the circle.  The formula for the area of a circle is:

Area = πr^(2)

So we take what we know and work the formula in reverse.

40,000 = πr²

40,000 / π = r²

12,732.4 = r²

√12,732.4 = √r²

112.84 = r

The radius of a circle with an area of 40,000 square miles is 112.84 miles.  This is the furthest point that you would be able to hear the broad cast.
