The ceiling of Victoria's living room is a square that is 15√2 ft long on each side. To decorate for a party, she plans to hang crepe paper around the perimeter of the ceiling and then from each corner to the opposite corner. Victoria can buy rolls that each contain 30 ft of crepe paper. what is the minimum number of rolls she should buy?

pls show your work

Answers

Answer 1

Answer:

Minimum 5 rolls

---------------------------------------

Total length we need is the sum of the perimeter and two diagonals of the square.

Perimeter:

P = 4s P = 4(15√2) = 60√2 ≈ 85 ft (rounded up to the whole number)

Diagonals:

2d = 2s√2 = 2(15√2)(√2) = 30*2 = 60 ft

Total length:

85 + 60 = 145 ft

Number of rolls:

145/30 ≈ 5 (rounded up to the whole number)

dierent number on each die. The six dice are rolled and the player wins a
prize depending on the total of the numbers which turn up.
(a) Find, as Cardano did, the expected total without nding its distribution.
(b) Large prizes were given for large totals with a modest fee to play the

Answers

As calculated from the data (1/6)² is the probability of getting 5 of same number on all the dice.

b.)If we will limit the number of winners then we will be able to provide them with large prizes and that also by taking moderate rate from everyone.

Actually, the likelihood of winning is closer to one-third (25/72).

Carnival game organizers want you to believe, like I did, that a game is fair so that you will participate.

The likelihood that you would win a game was just about 1/3, so you probably wouldn't squander your money.

Therefore,

The likelihood of getting five of the same number on all six dice is (1/6)².

Probabilities are mathematical representations of the likelihood that an event will occur or that a statement is true.

Probability can also be expressed using a tree diagram.

The tree diagram makes it easier to organize and see all of the potential outcomes. The tree's branches and ends are its two primary locations. On each branch is written the probability, and the ends hold the results in the end.

2 games at day   =    5/1/2023

2 games at day   =    10/1/2023

2 games at day   =    15/1/2023

You are doing a Diffie-Hellman-Merkle key exchange with Aisha using generator 7 and prime 437. Your secret number is 227. Aisha sends you the value 308. Determine the shared secret key.

Answers

Answer:

382^2 mod

Step-by-step explanation:

To determine the shared secret key, we need to use the formula (g^a mod p)^b mod p = (g^b mod p)^a mod p, where g is the generator, p is the prime, a is our secret number, and b is the value sent by Aisha. Plugging in the values, we get (7^227 mod 437)^308 mod 437 = (7^308 mod 437)^227 mod 437.

To solve for the shared secret key, we first need to calculate (7^308 mod 437). This can be done by raising 7 to the 308th power and then taking the remainder when divided by 437. We can do this by repeatedly squaring 7 and taking the remainder each time. This results in the following sequence:

7^2 mod 437 = 49

7^4 mod 437 = 161

7^8 mod 437 = 267

7^16 mod 437 = 9

7^32 mod 437 = 49

7^64 mod 437 = 161

7^128 mod 437 = 267

7^256 mod 437 = 9

7^512 mod 437 = 49

Since 512 is greater than 308, we can stop here and use the value 49 as the result of 7^308 mod 437. We can now plug this value into the formula to calculate the shared secret key: (49^227 mod 437)^308 mod 437 = (49^308 mod 437)^227 mod 437.

To solve for the shared secret key, we need to find the value of 49^308 mod 437. This can be done using the same method as before, by repeatedly squaring 49 and taking the remainder each time. This results in the following sequence:

49^2 mod 437 = 67

49^4 mod 437 = 382

49^8 mod 437 = 221

49^16 mod 437 = 67

49^32 mod 437 = 382

49^64 mod 437 = 221

49^128 mod 437 = 67

49^256 mod 437 = 382

Since 256 is greater than 308, we can stop here and use the value 382 as the result of 49^308 mod 437. We can now plug this value into the formula to calculate the shared secret key: 382^227 mod 437 = 382^227 mod 437.

To find the shared secret key, we need to calculate 382^227 mod 437. This can be done using the same method as before, by repeatedly squaring 382 and taking the remainder each time. This results in the following sequence:

An electric car battery, when fully charged, can travel 260 miles. The car uses 232 miles of charge on a drive.
Enter the percentage of miles the car has left in battery charge?

Answers

The percentage of miles the car has left in battery charge is 10.77%

Total distance traveled when fully charged = 260 miles

The total charged used by the car = 232 miles of charges

The remaining charges left in the car battery = Total distance traveled when fully charged - The total charged used by the car

Here we have to use the subtraction

Substitute the values in the equation

= 260 - 232

= 28 miles of charges

The percentage of miles the car has left in battery charge = (28/260) × 100

= 10.77%

Therefore, 10.77% miles of charge left in the battery

Answers

The number of hours taken by man to paint the whole garage alone is 31.5 hours.

Given that, one man can paint a garage in 28 hours.

What is time and work?

The basic concept of Time and Work is similar to that across all Arithmetic topics, i.e. the concept of Proportionality. Efficiency is inversely proportional to the Time taken when the amount of work done is constant.

Let x be number of hours taken by second man paint the whole garage.

Work done by first man be 1/28

So, work completed by first man =1/28 ×12

= 12/28

= 3/7

Remaining work is 1-3/7 =4/7

1/x ×18 =4/7

⇒ 18/x=4/7

⇒ 4x=126

⇒ x=126/4

⇒ x=31.5 hours

Ms.Jones bought a piece of cloth measuring 3 3/4 meters by 2 2/7. She bought the cloth at $14 per square meter. How much did Ms.Jones pay for the cloth?

Answers

Answer:

$120

Step-by-step explanation:

1) rewrite the mixed numbers into improper fractions. We do this by multiplying the denominator by the whole number, and then adding the numerator. The numerator stays the same:

[tex]3 \frac{3}{4} = \frac{(4 \times 3) + 3}{4} = \frac{15}{4} [/tex]

[tex]2 \ \frac{2}{7} = \frac{(7 \times 2) + 2}{7} = \frac{16}{7} [/tex]

So the length of the cloth = 15/4 meters

width of the cloth = 16/7 meters

2) Calculate the area of the cloth:

area = length × width

[tex]area \: = \: \frac{15}{4} \times \frac{16}{7} = \frac{240}{28} = \frac{60}{7} (simplest form)[/tex]

area = 60/7 m²

3) The cloth costs $14 per square meter, so the total cost of the cloth is:

the area of the cloth × cost of cloth per square meter

[tex]cost \: = \: \frac{60}{7} \times 14 = \frac{840}{7} = 120[/tex]

the cost is $120

Number of magazine lies between 3500 and 3600

Consider μ = 2 and σ = √2

Central limit theorem , we have

z =( [tex]\bar{X}[/tex] - μ )/ σ/√n

[tex]\bar{X}[/tex] = X / n

Probability of total number of magazine reads between ( 3500 to 3600)

28.8 km/hr = 28.8 km/hr * (1 hour / 3600 seconds) * (1000 meters / 1 km)

         = 8 meters/second

We can then use this value to find the time it takes Adil to complete the race:

time = distance / speed

   = 200 meters / 8 meters/second

   = 25 seconds

Since Adil takes 25 seconds to complete the race, and Tom takes 24 seconds, Tom wins the race.

g if the determinant of a matrix is , and the matrix is obtained from by adding times the second row to the first, then

Answers

Therefore the solution to the given matrix problem is  

a)det(B) = det(A) = 3  ,det(B) = 3*det(A) = 9  and c)det(B) = -det(A) = -3

What is matrix ?

A matrix is a rectangular array or table that contains numbers, symbols, or expressions that are arranged in rows and columns to represent a mathematical object or a characteristic of such an entity.

Here,

The following will be demonstrated using determinant properties:

A)Det(B) = 3

B) Det(B) = 9

C) det(B) = -3

Assuming A is a 4x4 matrix, we can see that:

det(A) = 3.

a) In this case, we are adding one row to another row by performing a transformation to the data in A. These operations don't alter the matrix's determinant, therefore in this instance:

det(B) = 3 = det(A)

b) If K is used to multiply a row of A to produce B, then:

B = det(K*det) (A).

In this situation, we have:

det(A) = 3*det(B) = 9

c) If we switch two rows around once (this is an odd permutation), the determinant's sign changes:

det(B) = -det(A) = -3

Answer:

Read carefully below

Step-by-step explanation:

We can use spherical coordinates to represent the points on the sphere. These coordinates are typically denoted as (r, θ, φ), where r is the radius of the sphere, θ is the polar angle, and φ is the azimuthal angle.

In order to find a parametric representation of the part of the sphere that lies inside the given cones, we can use the following approach:

First, we need to find the intersection of the sphere and the cone. This is the set of points that satisfy the equations of both the sphere and the cone.

Then, we can use spherical coordinates to represent these points on the sphere.

Finally, we can use these spherical coordinates as parameters in a parametric equation of the form x = x(r, θ, φ), y = y(r, θ, φ), z = z(r, θ, φ) to represent the points on the part of the sphere that lies inside the cone.

Let's use this approach to find a parametric representation of the part of the sphere that lies inside the cone z = 3(x^2 + y^2) in the first case.

To find the intersection of the sphere and the cone, we need to solve the following system of equations:

x^2 + y^2 + z^2 = 16 (equation of the sphere)

z = 3(x^2 + y^2) (equation of the cone)

Substituting the second equation into the first equation, we get:

x^2 + y^2 + 9(x^4 + y^4) = 16

This equation represents an ellipse in the xy-plane. We can use the parametric equations of an ellipse to represent the points on this ellipse:

x = a * cos(t)

y = b * sin(t)

where a and b are the semi-major and semi-minor axes of the ellipse, respectively, and t is a parameter that varies from 0 to 2π.

We can now use spherical coordinates to represent the points on the part of the sphere that lies inside the cone. We can let r be the radius of the sphere (r = 4), θ be the polar angle (0 ≤ θ ≤ π), and φ be the azimuthal angle (0 ≤ φ ≤ 2π).

The parametric equations of the sphere in spherical coordinates are:

x = r * sin(θ) * cos(φ)

y = r * sin(θ) * sin(φ)

z = r * cos(θ)

Substituting the equations for x and y from the ellipse into the equations for x and y from the sphere, we get:

x = 4 * sin(θ) * cos(φ) = a * cos(t)

y = 4 * sin(θ) * sin(φ) = b * sin(t)

z = 4 * cos(θ) = 3(x^2 + y^2) = 3(a^2 * cos^2(t) + b^2 * sin^2(t))

We can solve for a and b in terms of r and θ:

a = 4 * sin(θ)

b = 4 * sin(θ)

Therefore, the parametric equations for the part of the sphere that lies inside the cone z

What are the degree and leading coefficient of the polynomial?
-9-8w+3w+12w³

Answers

The degree of a polynomial is the highest power of the variable in the polynomial. In this case, the highest power of w is 3, so the degree of the polynomial is 3.

The leading coefficient of a polynomial is the coefficient of the term with the highest degree. In this case, the leading coefficient is 12.

In summary, the polynomial -9-8w+3w+12w³ has degree 3 and leading coefficient 12.
