Answer:
(x y) = (1 2/3, 4 2/3)
Step-by-step explanation:
We're not sure the basis you're intended to use for estimating. Perhaps you're given a graph, or are intended to draw a graph. The attachment from a graphing calculator is able to tell us what the point of intersection is.
(x, y) = (1 2/3, 4 2/3)
__
The only "estimate" we need to make is that 0.667 ≈ 2/3.
Answer:
The Triangle Sum Theorem is also called the Triangle Angle Sum Theorem or Angle Sum Theorem. It says that all the angles <em>inside</em> a triangle add up to 180°.
---------------------------------------------------------------------------------
Take a look at the picture attached. It has a "formula": ∠a+∠b+∠c=180°
Use this as it will help you a lot. You plug in the info you already know (it doesn't matter which angle is a,b,c) and solve for the missing one. :)
Ask in the comments below if you are not sure about something.
I hope that helps you! :D
Answer:
4 acres of wheat and 4 acres of rye.
Step-by-step explanation:
Given: Farmer has only 7 acre, he has plant at least 7 acres.
Farmer has only $1200 to spend.
Each acre of wheat will cost $200 and rye will cost $100.
Planting time is only 12 hours
Wheat planting take 1 hour per hour and rye take 2 hours per acre.
Profit on wheat is $500 per acre and rye $300 per acre.
As to find out maximum profit, we need to plant maximum wheat.
While dividing number of acres of land for wheat and rye for plantation, we need to keep two constraint in the mind; Constraint of cost and time as given.
Lets assume few number considering these constraint to get maximum profit.
First assumption, 5 acres of wheat and 2 acres of rye
Time taken=
Total time taken 7 hours
Amount spent=
Total cost is $ 1200.
Profit=
Maximum profit= $3100.
Second assumption, 4 acres of wheat and 4 acres of rye.
Times taken=
Total time taken is 12 hours
Amount spent=
Total cost is $1200.
Profit=
Maximum profit= $3200.
∴ By using hit and trail method, we can see that we are getting maximum profit when farmer is planting 4 acres of wheat and 4 acres of rye.
