A farmer wants to fence in a rectangular plot of land adjacent to the north wall of his barn. no fencing is needed along the bar

n, and the fencing along the west side of the plot is shared with a neighbor who will split the cost of that portion of the fence. if the fencing costs $10 per linear foot to install and the farmer is not willing to spend more than $4000, find the dimensions for the plot that would enclose the most area.

Let the length of the northern side be x and length of the west sides be y. The cost of fence is:
C=10x+10y+5y

and the area enclosed be A=xy
10x+15y=4000
x=400-1.5y
A=400y-1.5y^2
A is maximized when y=400/3 and x=200

What is the measure please help :)
mestny [16]

Answer:

40°

Step-by-step explanation:

m\angle A + m\angle B = 180\degree

(Linear pair angles)

140\degree + m\angle B = 180\degree

m\angle B = 180\degree -140\degree

m\angle B = 40\degree

The bread is on sale for $1.50 so Erica is also going to buy candy or gum. Which can she afford?
Alborosie
Ok, so she started off with $5.00. 


She bought milk for $2.99.

She buys bread, which costs $1.50. 

Subtracting the money she wasted, the total would be $0.51. 

The only thing she could buy is 5 pieces of gum for 25 cents. 

Her change will be $0.26. 

Hope this helps!

A factory makes 640brushes in 4 hours.Does the equation y=150x model the number of brushes made each hour?
adelina 88 [10]

Answer:

No it doesn't

Step-by-step explanation:

The equation we have is

Y = 150x

We have x = 4 hours

This is a simple question. We have to plug in the x = 4 in the equation to find out if we would have 640 brushes. If y = 640, then it models it. But if y is not equal to 640, it doesn't.

So let's solve this to see for ourselves.

Y = 150(x)

We put the value of x

Y = 150(4)

Y = 600

So we can see that the equation does not model the number of brushes made each hour. This equation models 600 brushes and not 640.

A toolbox contains a pile of mixed up pile of wrenches. The wrenches are all labeled with the dimension of their openings in fra
Sergio039 [100]
1.

     a)Two different methods for ordering these wrenches are either
     converting the measurements into decimal or converting them into
     fractions. 

     b) I chose to convert them into fractions with an LCD of 16. The fractions
     are: 8/16, 12/16, 6/16, 10/16, 5/16, 7/16, 11/16

     c) The ordered form of the fractions, from least to greatest, is 5/16, 3/8,
     7/16, 1/2, 5/8, 11/16, 3/4

2. I don't see how I can put them on a number line. 

3. The number line can definitely be used to support the answer from part C (if it is done correctly). That is because if the order on the number line is the same as the order in C, then we know that C is correct. In addition, since the number line includes benchmarks, we can easily see if the answer to C is incorrect.
