A farmer owns 30 acres of land on which he wishes to grow corn and barley. The cost per acre for seed corn is $30, and the cost

per acre for barley seed is $20. The farmer can invest a maximum of $600 in seed for the two crops. During the cultivation process, the farmer needs to spray fertilizers and insecticides specific to each crop. This costs $10 per acre for corn and $15 per acre for barley. He can invest only $400 in this process.
Part A: Write the two inequalities that are deciding factors for the number of acres of each crop the farmer will plant, based on the amount of money the farmer will spend on planting and cultivating the two crops.
Part B: Replace the inequality signs in the two inequalities with equal signs. Plot a graph representing the two equations choice of how much of each crop to grow using the Edmentum Graphing Tool and paste it into the box below.
Part C: Should the lines be dotted or solid? Give reasons for both lines. What area should be shaded?

prt a. 30c + 20b ≤

prtb. 5,23

prtc. solid,both equations were less than or equal to some value (non-strict inequality), which means that the boundary value (i.e., the line) is also included in the solution set.

The shaded should be below both lines and above both axes.

Alex777 [14]

Answer:

The number of pair of gym shoes does Mr. king has is 27 pairs .

Step-by-step explanation:

Given as :

Total number of pairs of shoes does king has = 36 pairs

The number of gym shoes = \dfrac{3}{4} of the total pairs of shoes

Let The number of pair of gym shoes = n

<u>According to question</u>

The number of gym shoes = \dfrac{3}{4}  × the total pairs of shoes

Or, n = \dfrac{3}{4}  × 36

i.e n = \frac{3\times 36}{4}

Or, n = 3 × 9

∴   n = 27

So, The number of pair of gym shoes = n = 27 pairs

The area A of a triangle with base b and height h is given by A = = bh. Find the area when b = 18 m (meters) and h = 30 m.
Pie

Answer:

Area = 270m^2

Step-by-step explanation:

Given

A = \frac{1}{2}bh

b = 18m

h = 30m

Required

Solve for A

Simply substitute 18 for b and 30 for h

A = \frac{1}{2}bh

A = \frac{1}{2} * 18 * 30

A = 270

Hence:

The area is

Area = 270m^2
