A farmer is building a fence to enclose a rectangular area against an existing wall, shown in the figure below.
A rectangle labeled, Fenced in Region, is adjacent to a rectangle representing a wall.
A rectangle labeled, Fenced in Region, is adjacent to a rectangle representing a wall.
Three of the sides will require fencing and the fourth wall already exists.
If the farmer has 164 feet of fencing, what is the largest area the farmer can enclose?
9514 1404 393
Answer:
3362 ft²
Step-by-step explanation:
As we saw in https://brainly.com/question/22284853, the long side of the area will be half the length of the fence: 82 feet. The remaining two sides will be 41 feet each, so the largest area that can be enclosed is ...
A = LW
A = (82 ft)(41 ft) = 3362 ft²

Erica decides to paint the birdhouse. She has a pint of
paint that covers 32.5 ft2 of surface. How can you tell that Kali has
enough paint without calculating?
Answer:
Step-by-step explanation:
If the birdhouse is a cube that is 2 ft on each edge, the surface area is 6×2² = 24 ft². That's a pretty large birdhouse, and it will need about ¾ of a pint of paint.

What is the hypotenuse and how do I get it?
Step-by-step explanation:
by Pythagoras theorem:
perpendicular² + base²= hypotenuse²
(1/√2)²+ (1/√3)² = H²
1/2+1/3= H²
5/6 = H²
√(5/6 )= H
√5/√6 = H

7.2.9-T Question Help Here are summary statistics for randomly selected weights of newborn girls: n= 157, x = 33.6 hg, s = 6.2 hg. Construct a confidence interval estimate of the mean. Use a 98% confidence level. Are these results very different from the confidence interval 32.3 hg
Answer:
The 98% confidence interval estimate of the mean is between 32.45 hg and 34.75 hg.
32.3 is not a part of the confidence interval, which means that yes, these results are very different from the confidence interval 32.3 hg
Step-by-step explanation:
We have that to find our [tex]\alpha[/tex] level, that is the subtraction of 1 by the confidence interval divided by 2. So:
[tex]\alpha = \frac{1 - 0.98}{2} = 0.01[/tex]
Now, we have to find z in the Ztable as such z has a pvalue of [tex]1 - \alpha[/tex].
That is z with a pvalue of [tex]1 - 0.01 = 0.99[/tex], so Z = 2.327.
Now, find the margin of error M as such
[tex]M = z\frac{\sigma}{\sqrt{n}}[/tex]
In which [tex]\sigma[/tex] is the standard deviation of the population and n is the size of the sample.
[tex]M = 2.327\frac{6.2}{\sqrt{157}} = 1.15[/tex]
The lower end of the interval is the sample mean subtracted by M. So it is 33.6 - 1.15 = 32.45 hg
The upper end of the interval is the sample mean added to M. So it is 33.6 + 1.15 = 34.75 hg
The 98% confidence interval estimate of the mean is between 32.45 hg and 34.75 hg.
Are these results very different from the confidence interval 32.3 hg
32.3 is not a part of the confidence interval, which means that yes, these results are very different from the confidence interval 32.3 hg

Answer:
885.2m²
Step-by-step explanation:
a is the side length of the square at the base
h is the height of the pyramid
Given
a = 18m
Get the height using the pythagoras theorem
h² =18²-9²
h² = 324 - 81
h² = 243
h = √243
h = 15.5884m
Area of the triangle = 1/2 * 18 * 15.5884
Area of the triangle = 9 * 15.5884
Area of the triangle = 140.2956m²
Area of the 4 triangles = 4(140.2956)
Area of the 4 triangles = 561.1824m²
Base area = 18 * 18
Base area = 324m²
Total surface area = Base area + Area of the 4 triangles
Total surface area = 324 + 561.1824
Total surface area = 885.1824
Total surface area = 885.2m² (to the nearest tenth)

3(7 + 13)
3(13 + 30)
7(3 + 13)
13(3 + 7)
Answer:
The last one is the answer
Step-by-step explanation:
39+91=130
13(10)=130
130=130
Answer:
13(3 + 7)
Step-by-step explanation:
First do 3 + 7 and that is 10.
Then do 10 x 13 and that is 130.
Finally compare 91 + 39 = 130 to 13(3 + 7)

The cable for a certain suspension bridge is modeled by a parabola with vertex (0,0) at the center of the bridge. At a point that is 150 ft from the center of the bridge, the height of the cable is 30 ft. Which equation represents the height of
the cable at a distance x feet from the center?
Answer:
Step-by-step explanation:
h(x)=ax^2
Given h=30 when x=150 we get
a(150)^2=30
a=30/22500=1/750 so
h(x)=x^2/750
The equation [tex]\rm h(x)= \frac{1}{750} x^2[/tex] represents the height of the cable at a distance x feet from the center.
It is given that the cable for a certain suspension bridge is modeled by a parabola with vertex (0,0).
It is required to derive the equation that represents the height of cable at a distance x feet from the center.
What is a parabola?It is defined as the graph of a quadratic function that has something bowl-shaped.
We have the bridge is modeled by a parabola with vertex (0,0)
We know the general equation of parabola:
[tex]\rm y= a(x-h)^2+k[/tex] with vertex (h,k)
Here the value of h = 0 and k = 0
[tex]\rm h(x)= ax^2[/tex] ( ∵ y = h(x) represented the function in terms of height)
We have h = 30 at x = 150 (From the question)
Putting the value of h and x in the parabola equation, we get:
[tex]\rm 30 = a(150)^2[/tex]
[tex]\rm a = \frac{1}{750}[/tex]
Putting the value of 'a' in the parabola equation, we get:
[tex]\rm h(x)= \frac{1}{750} x^2[/tex]
Thus, the equation [tex]\rm h(x)= \frac{1}{750} x^2[/tex] represents the height of the cable at a distance x feet from the center.
