Farmer planting corn and soybeans: A farmer has a 320 acre farm on which she plants two crops: corn and soybeans. For each acre

of corn planted, her expenses are $50 and for each acre of soybeans planted, her expenses are $100. Each acre of corn requires 100 bushels of storage and yields a profit of $60; each acre of soybeans requires 40 bushels of storage and yields a profit of $90. If the total amount of storage space available is 19,200 bushels and the farmer has only $20,000 on hand, how many acres of each crop should she plant in order to maximize her profit? What will her profit be if she follows this strategy?

Answer:

Let x represents acres of corn to be planted.

Let y represents acres of soybeans to be planted.

A farmer has a 320 acre farm on which she plants two crops. We get;

x+y\leq 320

Other equations as per scenario becomes:

x\geq 0

y\geq 0

50x+100y\leq 20000

100x+40y\leq 19200

We have to find the profit. So let the profit be p. We can give this by:

p(x,y)=60x+90y

When we graph these functions, we get the following.

(0,200) putting these in p(x,y)=60x+90y we get profit as $1800

(140,130) , we get $20,100

(192,0) we get $11520

In the graph, we have points (240,180) but this is not possible as x+y\leq 320 so, we have (140,130) to get the maximum profit.

sinE is 0.5

What are similar triangles?

Two triangles will be similar if the angles are equal (corresponding angles), and sides are in the same ratio or proportion (corresponding sides). Similar triangles may have different individual lengths of the sides of triangles, but their angles must be equal and their corresponding ratio of the length of the sides must be the same.

Clearly, given triangle AFB and triangle DFE are similar.

We know that Similar Triangles have the same corresponding angle

We can find sinE as show below:

From diagram clearly

∠A=∠E

and ∠B=∠D

Since, ∠A=∠E

Taking sin on both sides

sinA=sinE

Give, sinA=0.5

sinA=sinE=0.5

⇒ sinE=0.5

Hence, sinE is 0.5

In order for the parallelogram to<br> be a square, x=?
iren [92.7K]

Answer:

<h2>7°</h2>

Step by step explanation

We know that the diagonals of a square bisects it's angles and every angles of square are 90°

m<BCD = 90°

m<BCA = m< DCA = 4x + 17

m<BCA + m<DCA = m <BCD

4x + 17 + 4x + 17 = 90

4x + 4x + 17 + 17 = 90

8x + 34 = 90

8x = 90 - 34

8x = 56

X = 56/8

x = 7

Hope this helps...

Good luck on your assignment...
