Tina is planning to fence in an area for her dog. She wants to create a rectangular area of 1,600 square feet for her pet and can afford to purchase 160 feet of fence. In two or more complete sentences, explain the algebraic model, calculations and reasoning necessary to determine the dimensions of the rectangular area.

Answers

Answer 1

The dimensions of the rectangular area of Tina's fence is 40 ft by 40 ft

Area of a rectangle:area = lw

where

l = length

w = width

She wants to create a rectangular area of 1,600 square feet for her pet . Therefore,

area = 1600 ft²

lw = 1600

Therefore,

perimeter = 160 ft

Then,

perimeter of rectangle = 2(l + w)

160 = 2(l + w)

l + w = 80

Let's combine the equations

lw = 1600

l + w = 80

l = 80 - w

Therefore,

w(80 - w) = 1600

80w - w² = 1600

Therefore,

w² - 80w + 1600 = 0

w² - 40w - 40w + 1600 = 0

w(w - 40) - 40(w - 40) = 0

(w - 40)(w - 40) = 0

w = 40 or 40

Therefore, the dimensions can be calculated as follows:

lw = 1600

40l = 1600

l = 1600 / 40

l = 40 ft

Therefore, the dimensions are 40ft by 40 ft

A semicircle is drawn onto one of the shorter sides of a rectangle. The shorter side of the rectangle measures 4 centimeters. The area of the figure is 41.4 square centimeters.

What is the length of the longer side of the rectangle?

Use 3.14 for π.

Enter your answer as decimal in the box.

Answers

Answer:

8.78 cmSolution:

We are given that :

A semicircle is drawn onto the shorter side of rectangle.Shorter side of rectangle measures 4cm. i.e; the diameter of the circle is 4cmArea of the figure is 41.4 cm²

Using Formulas:

Area of rectangle:

[tex] \quad\hookrightarrow\quad{\pmb{ \mathfrak {length\times breadth }}}[/tex]

Area of semicircle:

[tex] \quad\hookrightarrow\quad{\pmb{ \mathfrak{ \dfrac{\pi r^2 }{2}}}}[/tex]

We have to find the length of longer side of rectangle!

Here, we can know that the figure is composed of one rectangle and one semicircle. Therefore by combining the areas of rectangle and circle and taking the length of rectangle as a variable , we will finds its value ;

[tex] \quad\dashrightarrow\quad \sf {Area_{\tiny { total}} = Area_{\tiny {rectangle}}+ Area_{\tiny {semicircle}}}[/tex]

[tex] \quad\dashrightarrow\quad \sf {A = ( l \times b ) + \dfrac{\pi r^2 }{2} }[/tex]

[tex] \quad\dashrightarrow\quad \sf {41.4 = ( l \times 4 ) +\dfrac{3.14\times 2^2}{2} }[/tex]

[tex] \quad\dashrightarrow\quad \sf { 41.4= ( l \times 4 )+ \dfrac{ 3.14\times 4}{2}}[/tex]

[tex] \quad\dashrightarrow\quad \sf { 41.4=( l \times 4 )+ \dfrac{12.56}{2}}[/tex]

[tex] \quad\dashrightarrow\quad \sf { 41.4= (l \times 4 )+ 6.28}[/tex]

[tex] \quad\dashrightarrow\quad \sf {l \times 4 = 41.4-6.28 }[/tex]

[tex] \quad\dashrightarrow\quad \sf { l\times 4 = 35.12}[/tex]

[tex] \quad\dashrightarrow\quad \sf { l =\dfrac{35.12}{4}}[/tex]

[tex] \quad\dashrightarrow\quad \underline{\underline{\pmb{\sf {l = 8.78\:cm}}} }[/tex]

The length of the longer side of the rectangle will be 8.78 cm.

What is the area?

The area of a two - dimensional figure is the area that its perimeter encloses. The quantity of unit squares that occupy a closed figure's surface is its region.

On one of a rectangle's shorter sides, a semicircle is drawn. The rectangle's shorter side is 4 cm long. The figure has a surface area of 41.4 square centimeters.

Then the length of the rectangle is calculated as,

A = πr² / 2 + l × b

41.4 = (3.14 / 2) × (4/2)² + 4l

41.4 = 6.28 + 4

l = 8.78 cm

The length of the longer side of the rectangle will be 8.78 cm.

4. If the area of a rectangle is 6 m2, then the dimensions must be 2 meters by 3 meters. oh

Answers

Answer:

False.

Step-by-step explanation:

The formula that is used to find the area of a rectangle is given by :

A = l×b

Where,

l is length and b is breadth

If area of a rectangle is 6m², it means we need to find the factors of 6. The factors of 6 are 2 and 3. If we multiply 2 and 3, we get 6.

Other possibility can be 1 m by 6 m because if we muliply 1 m and 6 m, we get 6m².

It means there are more than one possibiliy about the length and breadth of the rectangle.

Hence, the given statement is not true.

This figure has two intersecting lines and a ray. What is the value of x?




108°


72°


19°


37°

Answers

Answer: The answer is 37

Step-by-step explanation:

If you subtract 71 from 108 the answer is 37

Since the angles of (x + 71)º is opposite to the same vertex to the angle of 108º, it is found that x = 37º.

The ray generated two angles, xº and 71º.Adding these angles, there is an angle of (x + 71)º, which is opposite to the same vertex to the angle of 108º, meaning that they have the same measure.

Applying the equality:

[tex]x + 71 = 108[/tex]

[tex]x = 108 - 71[/tex]

[tex]x = 37[/tex]

Thus, x = 37º.

These are values that show the position of an object, these values often include a number for the x-axis (horizontal axis) and one for the y-axis (vertical axis).

What are the positions of the referee, the back judge, and the field judge?

If we consider the ball as 0 or the starting point the coordinates are:

While reviewing last month's finances, Oscar noticed that he had spent $200 on a wedding cake and deposited $500 that he had earned from selling books to a used bookstore. ​ ​Then, he again spent $127 to buy some new books. Which integer represents the change in Oscar's savings?

Answers

Answer:

$173

Step-by-step explanation:

Given the following :

Amount spent on wedding cake = $200

Amount deposited = $500

Amount spent on new books = $127

Change in savings :

Amount deposited - total amount spent

Total amount spent = ($200 + $127).= $327

Hence,

Change in saving = $500 - $327

= $173

The average number of customers that visited a particular store during the past year is 200 per day and a standard deviation of 25 customers per day. The probability that x>200 is:

Answers

Answer:

0.5

Step-by-step explanation:

Considering we are given a mean and standard deviation, the distribution of the data is likely to be a normal or Gaussian distribution, i.e. a symmetrical, bell-shaped distribution of probability density, peaked at the mean;

Such a distribution has 0.5 probability each side of the mean;

So, if the mean is 200 then, the probability that the number of customers is greater than 200 (x > 200), according to this mean, is 0.5;

As a normal distribution is symmetrical, this is also the probability of a number of customers less than 200.
