Wright a real world problem that involves classifying a quadrilateral. Then solve the problem.

Answers

Answer 1
An amusement park ride has a moving platform attached to four swinging arms. The platform swings back and forth, higher and higher, until it goes over the top and around in a circular motion. In the diagram below, AD and BC represent two of the swinging arms, and DC is parallel to the ground (line l). Explain why the moving platform AB is always parallel to the ground.


The shape of quadrilateral ABCD changes as the moving platform swings around, but its side lengths do not change. Both pairs of opposite sides are congruent, so ABCD is a parallelogram by Theorem 8.7.By the definition of a parallelogram, AB DC . Because DC is parallel to line l, AB is also parallel to line l by the Transitive Property of Parallel Lines. So, the moving platform is parallel to the ground.

see the attached picture:
  1st find the median, which would be the middle of the data set. Since there are 9 numbers the median would be the middle number of the set, this would give you the same amount of numbers on each side of it. The numbers to the left would be the lower and the numbers on the right would be the upper
 so in the given data set the median is 29

the lower quartile is the median of the lower numbers, in this case the numbers below 29 are 20, 22 , 25, 28
 since there is an even amount of numbers you need to add the 2 middle numbers together and divide by 2 to find the lower quartile so 22 +25 = 47, 47 / 2 = 23.5 this is the lower quartile
 the upper quartile is found the same way, but using the upper numbers so in this case using 30, 32, 33 , 34
 add the 2 middle numbers 32 +33 = 65 divide by 2 = 65/ 2 = 32.5 this is the upper quartile
 the inter quartile range is subtracting the lower quartile from the upper quartile: 32.5 - 23.5 = 9
 9 is the inter quartile range






According to the information we can infer that the Lower Quartile is 23.5, the upper quartile is 32,5, and the interquartile range is 9.

How to calculate these information?

Arrange the data in ascending order: 20, 22, 25, 28, 29, 30, 32, 33, 34.

Calculate the position of the lower quartile using the formula: (n + 1) / 4, where n is the number of data points.

(9 + 1) / 4 = 10 / 4 = 2.5

Since 2.5 falls between the 2nd and 3rd data points, you need to find the average of these two values:

(22 + 25) / 2 = 47 / 2 = 23.5

Upper Quartile (Q3):

Calculate the position of the upper quartile using the formula: 3 * (n + 1) / 4.

3 * (9 + 1) / 4 = 30 / 4 = 7.5

Since 7.5 falls between the 7th and 8th data points, find the average of these two values:

(32 + 33) / 2 = 65 / 2 = 32.5

Interquartile Range (IQR):

Calculate the IQR by subtracting Q1 from Q3:

IQR = Q3 - Q1 = 32.5 - 23.5 = 9.

So, the lower quartile (Q1) is 23.5, the upper quartile (Q3) is 32.5, and the interquartile range (IQR) is 9.

Answers

The interquartile range is 12.5.

We first find the median.  To do this, order the data from least to greatest and find the middle value:
72, 80, 81, 84, 92, 92, 94, 95

There are 8 data values.  The median is between 84 and 92:
(84+92)/2 = 176/2 = 88

The median splits the data into two halves.  The lower quartile is the median of the lower half; this is between 80 and 81:
(80+81)/2 = 161/2 = 80.5

The upper quartile is the median of the upper half; this is between 92 and 94:
(92+94)/2 = 186/2 = 93

The interquartile range is found by subtracting these:
93-80.5 = 12.5

Answer:

upper quartile is 93

lower quartile is 80.5

The picture below shows a container that Rene uses to freeze water: A cylinder is shown with base diameter of 6 centimeters and the height as 8 centimeters. What is the minimum number of identical containers that Rene would need to make 2000 cm3 of ice? (Use π = 3.14.)

Answers

The cylinder has base diameter of 6 centimeters and the height, [tex] h [/tex], of 8 centimeters.

Since the base diameter of the cylinder is 6 cm, therefore, it's radius, [tex] r [/tex], will be 3 cm.

Now, we know that the volume, [tex] V [/tex], of such a cylinder will be:

[tex] V=\pi r^2h [/tex]

Plugging in the values given we get the volume to be:

[tex] V=\pi(3)^2\times 8=3.14\times9\times8=226.08 [/tex] [tex] cm^3 [/tex]

Since Rene needs to make 2000 [tex] cm^3 [/tex] of ice and one cylinder's volume is 226.08 [tex] cm^3 [/tex], Rene would need...

[tex] \frac{2000}{226.08}\approx8.846\approx\boldsymbol{9} [/tex] such identical cylindrical containers.


Final answer:

To make 2000 cm3 of ice, Rene would need a minimum of 9 identical containers, given the volume of one container is 226.08 cm3.

Explanation:

To determine the number of identical cylindrical containers needed to make 2000 cm3 of ice, we must first calculate the volume of one container. Given that the diameter of the base is 6 centimeters, the radius (r) is half of that, which is 3 centimeters. We're also given the height (h) of 8 centimeters. We can use the formula for the volume of a cylinder, V = πr2h.

Plugging in the values, we get:

V = 3.14 × (3 cm)2 × 8 cm

which simplifies to V = 3.14 × 9 cm2 × 8 cm = 226.08 cm3.

Now we can divide the total volume of ice Rene wants to make by the volume of one container:

2000 cm3 ÷ 226.08 cm3 = approx 8.85.

Since Rene cannot use a fraction of a container, she would need a minimum of 9 identical containers to make at least 2000 cm3 of ice.

Two roast beef wraps is $4.50 * 2 = $9.
One soup added to that is $11.25, plus the fries is $12.75.
Two coffees is $ 1.80, so your total meal cost by its self was $14.55.
Multiply that by 1.05 for tax to get $15.2775.
Multiply $14.55 by 0.15 to get $2.1825.
Add $15.2775 and $2.1825 to get $17.46.
Subtract $ 17.46 from $20 to get $2.54.
Answer:

Part A:

The most expensive item on the menu is roast beef wrap at $4.50

6% tax on it becomes: [tex]4.50+(0.06\times4.50)=4.77[/tex] dollars

15% tip on it becomes: [tex]4.77+(0.15\times4.77)=5.485[/tex] dollars

The least expensive item on the menu is coffee at $0.90

6% tax on it becomes: [tex]0.90+(0.06\times0.90)=0.954[/tex] dollars

15% tip on it becomes: [tex]0.954+(0.15\times0.954)=1.097[/tex] dollars

So, the difference between roast beef wrap and coffee cost is :

[tex]5.485-1.097=4.388[/tex] dollars nearest to $4.36

Option B is the answer.

Part B:

You and your friend ordered two roast beef wraps, one soup, one fries, and two coffees.

Total becomes:

[tex](2\times4.50)+(2.25)+(1.50)+(2\times0.90)[/tex]

= [tex]9+2.25+1.50+1.8=14.55[/tex] dollars

Sales tax of 5% and 15% tip means 20% more on $14.55

[tex]14.55+(0.20\times14.55)=17.46[/tex] dollars

Change you will receive = [tex]20-17.46=2.54[/tex]dollars

Tom bought 7 books. He has space only for 3 books in his bookshelf. In how many ways can he arrange the 3 books?

Answers

That's 7P3, or 7!/4!, or 210.

The required, Tom can arrange the 3 books in the combination of 35 different ways on his bookshelf.

The number of ways to choose a subset of 3 books from a set of 7 books can be calculated using the combination formula:

C(n, k) = n! / (k!(n-k)!)

Where n is the total number of items and k is the number of items we want to choose.

In this case, Tom wants to arrange 3 books out of a set of 7 books. Using the combination formula, we have:

C(7, 3) = 7! / (3!(7-3)!)

= 7! / (3!4!)

Calculating the factorials:

7! = 7 * 6 * 5 * 4 * 3 * 2 * 1 = 5040

3! = 3 * 2 * 1 = 6

4! = 4 * 3 * 2 * 1 = 24

Substituting these values into the formula:

C(7, 3) = 5040 / (6 * 24)

= 5040 / 144

= 35

Therefore, Tom can arrange the 3 books in 35 different ways on his bookshelf.

Suppose you have two hyperbolas that are the same except that the transverse axis and conjugate axis are switched. How does switching the axes affect the equations of the asymptotes for the two hyperbolas? Why?

Answers

check the picture below.

assuming both hyperbolas at centered at the origin, the values for the numerator and denominator will switch, so that the slope of one is the reciprocal of the other's slope.

Final answer:

Switching the axes of two hyperbolas affects the equations of the asymptotes.

Explanation:

When the transverse axis and conjugate axis are switched in two hyperbolas, it affects the equations of the asymptotes. The equations of the asymptotes are determined by the ratio of the coefficients of x² and y² in the hyperbola equation. When the axes are switched, this ratio changes, resulting in different equations for the asymptotes.

For example, let's consider two hyperbolas with equations:

1) 8x² + 10xy - 3y² - 2x - 4y - 2 = 0

2) 8y² + 10xy - 3x² - 2x - 4y - 2 = 0

In the first hyperbola, the ratio of the coefficients of x² and y² is 8/(-3), which determines the equation of the asymptotes. In the second hyperbola, the ratio is (-3)/8, leading to different equations for the asymptotes.

A rectangular field is four times as long as it is wide. if the perimeter of the field is 340 ​yards, what are the​ field's dimensions

Answers

let the width of the field =  x.
Then the length = 4x 
Now the perimeter = 2 * length + 2 * width, so we have the equation:-
 2*4x + 2x = 340
8x + 2x = 340
10x = 340
x = 34 yards  = width
4x =  length = 136
Answer: the width is 34 yards and length is 136 yards. 

The required dimensions of the rectangular field are 34 yards by 136 yards.

What is the perimeter of the rectangle?

The perimeter of a rectangle is defined as the addition of the lengths of the rectangle's four sides.

The perimeter of a rectangle = 2(L+W)

Where W is the width of the rectangle  and L is the length of the rectangle

Let's represent the width of the field x. Since the field is four times as long as it is wide, the length of the field is 4x.

The perimeter of the field is the sum of all four sides of the field. This can be written as:

2(x) + 2(4x) = 340

Solving this equation for x, we find that the width of the field is x = 34 yards.

Since the length of the field is four times the width of the field, the length of the field is 4 × 34 = 136 yards.

Therefore, the width of the field is 34 yards, and the length of the field is 136 yards.
