La longitud del jardín es [tex]l \approx 44.72\,m[/tex]. (Opción A) (The length of the garden is [tex]l \approx 44.72\,m[/tex]) (Option A)

Step-by-step explanation:

El largo del jardín se calcula por el Teorema de Pitágoras (The length of the garden is now calculed by the Pythagorean Theorem):

[tex]l = \sqrt{(60\,m)^{2}-(40\,m)^{2}}[/tex]

[tex]l \approx 44.72\,m[/tex]

Answer:

A)  x = 44,72 m

Step-by-step explanation:

A rectangular shape means two dimensions width (w) and length (l)  and the internal angles are of 90⁰; therefore if we know one of its side, and a diagonal (d)  we can calculate the other side, using Pytagoras Theorem, then:

x² +  l²  = d²

x²  =  d² - l²    ⇒  x²  =  (60)²  - (40)²    ⇒   x² =  3600 - 1600

x²  =  2000

x = √2000

x = 44,72 m

The school has collected $1050.

The width of the base of the rectangular pyramid is 6 inches, which is found by rearranging and simplifying the formula for the volume of a pyramid using the given values for the pyramid's volume, height, and length.

The student has asked about finding the width of the base of a rectangular pyramid with a known volume, height, and base length. To find the width (w), we use the formula for the volume of a pyramid: V = (1/3) × base area × height. The base area is the product of the base length (l) and width (w), so we can rewrite the equation as V = (1/3) × l × w × h, where

Given that V = 1512 in³, h = 12 in, and l = 21 in, the equation becomes 1512 = (1/3) × 21 × w × 12. Simplifying, we find w = 1512 /​ (1/3 × 21 × 12), which calculates to 6 in. Hence, the width of the base of the pyramid is 6 inches.

Answer:

Probability that the card Connor chooses has a number on it that is even or divisible by 5 is (3/5) or 0.6.

Step-by-step explanation:

We are given that Connor randomly chooses a card from a deck of numbered cards. the cards are numbered 1 through 10, and each number appears only one time.

And we have to find the probability that the card Connor chooses has a number on it that is even or divisible by 5.

Let the Probability that card Connor chooses has a number on it that is even = P(A)

Probability that card Connor chooses has a number on it that is divisible by 5 = P(B)

Probability that card Connor chooses has a number on it that is even and divisible by 5 =  [tex]P(A\bigcap B)[/tex]

Probability that card Connor chooses has a number on it that is even or divisible by 5 =  [tex]P(A\bigcup B)[/tex]

Here, Even numbers are = {2, 4, 6, 8, 10} = 5

Numbers divisible by 5 = {5, 10} = 2

Also, Number which is even and also divisible by 5 = {10} = 1

Total numbers = 10

Now, Probability that card Connor chooses has a number on it that is even =  [tex]\frac{5}{10}[/tex]  = 0.5

Probability that card Connor chooses has a number on it that is divisible by 5 =  [tex]\frac{2}{10}[/tex]  = 0.2

Probability that card Connor chooses has a number on it that is even and divisible by 5 =  [tex]\frac{1}{10}[/tex]  = 0.1

Now,     [tex]P(A\bigcup B) = P(A) +P(B) -P(A\bigcap B)[/tex]

                             =  0.5 + 0.2 - 0.1

                             =  0.6  =  [tex]\frac{3}{5}[/tex]

Hence, probability that the card Connor chooses has a number on it that is even or divisible by 5 is 0.6.

The solution to the system of equations y = 1/2x - 4 and y = 2x - 9 is x = -2 and y = -5.

To find the solution to the system of equations y = 1/2x - 4 and y = 2x - 9, we need to find the values of x and y that satisfy both equations. We can do this by finding the points of intersection between the two lines graphically or by solving the equations algebraically.

Graphically, we can plot the two lines on a graph and see where they intersect. The points of intersection are (-2, -5) and (2, -3).

Algebraically, we can set the two equations equal to each other and solve for x:

1/2x - 4 = 2x - 9

Now solve for x:

x = -2

Then substitute the value of x back into one of the original equations to find the value of y:

y = 1/2(-2) - 4 = -5

So the solution to the system of equations is x = -2 and y = -5.

Answer:

900,000 books.

Step-by-step explanation:

The volume of the container = 24 * 9 * 8

= 1728 m^3

The volume of each book = 20*16*6 = 1920 cm^3

There are 100*100*100 = 1,000,000 cm^3 in 1 m^3.

So the number of books the container can hold

=   (1728 * 1000000) / 1920

= 900,000.

Final answer:

To organize the results into a two-way frequency table, fill in the known values and calculate the remaining values based on the total number of students.

Explanation:

To organize the results into a two-way frequency table, we can use the information given. First, we know that 6 students play both a musical instrument and a sport. We also know that 3 students play neither a musical instrument nor a sport. Furthermore, we know that a total of 14 students play a sport. From this information, we can fill in the table:

Plays a sport Does not play a sport

Plays a musical instrument 6 To be filled

Does not play a musical instrument To be filled 3

We can calculate the values for the empty cells by subtracting the known values from the total. So, the number of students who play a musical instrument but do not play a sport is 24 - (6 + 3 + 14) = 1. Likewise, the number of students who do not play a musical instrument but play a sport is 24 - (6 + 3 + 14) = 1.

Step-by-step explanation:

20 divided by 8 20 being the plants 8 being the length gives u 2.5

Rounding to the nearest hundredth, the distance between each plant will be approximately 1.26 feet.

To find the distance between each plant when they are evenly spaced around the edge of the circular garden, we can use the formula for the circumference of a circle:

[tex]Circumference (C) = \pi * diameter[/tex]

Rounding to the nearest hundredth, the distance between each plant will be approximately 1.26 feet.

Given that the diameter of the circular garden is 8 feet, we can calculate the circumference:

[tex]C = \pi * 8[/tex]

Now, let's calculate the circumference:

[tex]C = \pi * 8[/tex]

[tex]C = 3.14 * 8[/tex]

[tex]C = 25.12 feet[/tex]

Now, since there are 20 plants evenly spaced around the circumference, we can divide the circumference by 20 to find the distance between each plant:

[tex]Distance between plants = Circumference / Number of plants[/tex]

[tex]Distance between plants =25.12 / 20[/tex]

[tex]Distance between plants = 1.256 feet[/tex]

Without the bar chart data, the exact total profit for Milk & Cookies' from July through September cannot be calculated. Normally, you would add the monthly profits to find the total profit for the quarter.

To determine Milk & Cookies' total profit from July through September, we would need to examine the provided bar chart that lists profits for each month. However, since the actual bar chart data is not included in the question, we cannot calculate the exact total profit.

In a typical situation, you would add the profit of each month: Profit in July + Profit in August + Profit in September to find the total profit for that quarter.

If the total profits for July, August, and September are positive when added together, then Milk & Cookies has made a profit over these months.

If the sum is zero, the business broke even, and if the sum is negative, the business incurred a loss during that period. The profits from the bar chart are essential to conduct this analysis.

Answer:

Step-by-step explanation:

The measure of ∠X is approximately 47.9 degrees to the nearest tenth of a degree.

To find the measure of ∠X in triangle WXY, you can use the trigonometric relationship of the tangent function.

Given that ∠Y is a right angle (90°), and you have the lengths of two sides, WX and XY, you can use the following relationship:

tan(∠X) = opposite/adjacent

In this case:

Opposite side to ∠X = WX

Adjacent side to ∠X = XY

So, you have:

tan(∠X) = WX / XY

tan(∠X) = 7.9 feet / 6.7 feet

Now, you can find ∠X by taking the arctan (inverse tangent) of this value:

∠X = arctan(7.9 / 6.7)

Using a calculator, you can find:  

∠X ≈ 47.9 degrees (rounded to the nearest tenth of a degree)

Answer:

the degree of homogeneity is 20.

Step-by-step explanation:

In a polynomial P (x, y), homogeneous and complete in "x" and "y", the sum of the absolute degrees of all its terms is 420. What is its degree of homogeneity?

A homogeneous polynomial is one in which all monomials have the same degree.

This is an example of a homogeneous polynomial of degree 4 (the degree of all monomials is 4):

x ^ 4 + 3x ^ 3y + 2x ^ 2y ^ 2 + xy ^ 3 + 8y ^ 4.

As you can see, the sum of the exponents of the variables x, y in each monomial is 4.

And the number of terms is 5, that is, it is the degree of homogeneity plus 1.

In relation to the sum of the absolute degrees of all monomials or terms it will be: 4 + 4 + 4 + 4 + 4 = 4 * 5 = 20.

In general, you can say that the sum of the absolute degrees in a homogeneous polynomial will be the degree of each monomial by the number of terms = degree * (degree + 1)

Calling n, the degree of our polynomial, it must be fulfilled:

n (n + 1) = 420

=> n ^ 2 + n = 420

=> n ^ 2 + n - 420 = 0

Factoring:

(n + 21) (n - 20) = 0

=> n = -21 and n = 20.

Only the positive value makes sense, therefore n = 20.

In other words, the polynomial is of the form (excluding the coefficients):

x ^ 20 + x ^ 19 y + x ^ 18 y ^ 2 + x ^ 17 y ^ 3 + .... x ^ 3 y ^ 17 + x ^ 2y ^ 18 + xy ^ 19 + y ^ 20

That polynomial has 21 terms.

So the sum of the degrees will be 20 * 21 = 420, as required in the statement.

Therefore, the degree of homogeneity is 20.

Amount spent on each item is;

brush = $3.50

sketchbook = $14.00

paint set = $21.00

Completed question:

Madison brought $42.50 to the art supply store. She bought a brush, a sketchbook, and a paint set. The brush was 1/4 as much as the sketchbook, and the sketchbook cost 2/3 the cost of the paint set. Madison had $4.00 left over after buying these items. How much is each item.

Step-by-step explanation:

Let x,y and z represent the price of brush, sketchbook and paint set respectively.

The brush was 1/4 as much as the sketchbook,

x = 1/4 × y

y = 4x ....1

the sketchbook cost 2/3 the cost of the paint set

y = 2/3 × z

3y = 2z

z = 3y/2

Substituting equation 1

z = 3(4x)/2 =6x

z = 6x ....2

Total amount spent = amount he brought - amount he left with(remainder)

= $42.50 - $4.00

= $38.50

Total amount spent = x+y+z = $38.50

x+y+z = 38.50

Substituting equation 1 and 2

x + 4x + 6x = 38.50

11x = 38.50

x = 38.50/11

x = 3.5

y = 4x = 4(3.5) = 14

z = 6x = 6(3.5) = 21

Amount spent on each item is;

brush = $3.50

sketchbook = $14.00

paint set = $21.00

Height of a cone is 15.2 inches

It is required to find the volume of a cone. The volume of a cone is given in terms of radius r and height h as :

d = 11.5 inches

Radius, r = 5.75 inches

[tex]V=\dfrac{1}{3}\pi r^2 h\\\\V=\dfrac{1}{3}\times 3.14\times (5.75)^2\times 15.2\\\\V=526\ \text{inches}^3[/tex],

So, the volume of a right circular cone is [tex]526\ \text{feet}^3[/tex].

Final answer:

To find the volume of a cone with a given diameter and height, use the formula V = (1/3)πr²h where r is the radius and h is the height.

Explanation:

Volume of a cone:

Given diameter = 11.5 inches, radius = 11.5 / 2 = 5.75 inches

Using the formula V = (1/3)πr²h, plug in radius = 5.75 inches and height = 15.2 inches

Calculate the volume: V = (1/3) × 3.142 × (5.75)² × 15.2 inches³
