This coal bag has a minimum weight of 2.925 kilograms.

We must determine the coal's minimum weight, which is 30 pieces.

One piece of coal weighs 100 g, accurate to the closest 5 g. As a result, the actual weight of a piece of coal may range between 97.5 g to 102.5 g.

We can multiply the minimum weight of one piece of coal (97.5 g) by 30 to determine the minimum weight of 30 pieces of coal:

Minimum weight of 30 pieces of coal = 97.5 g x 30 = 2925 g

Therefore, The sticker can be finished as follows:

The value of x will be 18.67 for the given data of the triangle.

We have,

Thale's theorem:

When a line parallel to one side of a triangle intersects the other two sides in distinct points, the other two sides are divided in the same ratio.

Given that the sides of the triangle are divided into two parts,

For the left part the parts will be x and x + 7 for the right side the parts will be 16 and 22.

The ratio will be the same according to Thale's theorem. The value of x will be calculated as:-

x / ( x + 7 ) = 16 / 22

22x = 16x + 112

6x = 112

x = 112 / 6

Step-by-step explanation:

Square root of 64 = 8

The lateral surface area of the square pyramid is  176 in².

The first thing we need to do is find the slant height of the pyramid, which is the height of each of the triangular faces. We can use the Pythagorean theorem to do this:

slant height² = height² + (1/2base)²

slant height² = 7² + (1/28)²

slant height² = 49 + 16

slant height² = 65

slant height = √(65)

Now that we have the slant height, we can find the lateral surface area by multiplying the perimeter of the base by half the slant height. The perimeter of the base is simply 4 times the length of one of the sides, which is 8 inches.

lateral surface area = (perimeter of base * slant height) / 2

lateral surface area = (4 * 8 * √(65)) / 2 lateral surface area = 16 * √(65)

To simplify the radical, we can factor out any perfect squares that are factors of 65:

lateral surface area = 16 * √(65)

lateral surface area = 16 * √(513)

lateral surface area = 16 * √(5) * √(13)

lateral surface area = 16 * √(5) * √(43.25)

lateral surface area = 16 * √(5) * (2 * √(3.25))

lateral surface area = 64 * √(5) = 176.42 square inches.

The given angle measurements are same side interior angles. Therefore, the summation of the two angle measurements will equal 180° (Forming a straight line).

Set the two angle measurements equal to 180:

[tex](3x + 3) + (45) = 180[/tex]

Simplify. First, combine like terms. Like terms are terms that share the same amount of the same variables. In this case, combine 3 with 45:

[tex]3x + 3 + 45 = 180\\3x + (3 + 45) = 180\\3x + (48) = 180[/tex]

Next, isolate the variable, x. Note the equal sign, what you do to one side of the equation, you do to the other. Do the opposite of PEMDAS.

PEMDAS is the order of operations, and stands for:

Answer:

To determine the day and time 7777 hours later in Washington, D.C., we first need to determine the time difference between Portland, Oregon, and Washington, D.C. Portland is in the Pacific Time Zone, while Washington, D.C., is in the Eastern Time Zone. The time difference between the two zones is 3 hours, with Eastern Time being ahead of Pacific Time.

So, if it is 7:00 a.m. in Portland, it would be 10:00 a.m. in Washington, D.C.

Next, we need to calculate the number of days that pass in 7777 hours. Since there are 24 hours in a day, we can divide 7777 by 24 to get the number of days:

7777 ÷ 24 = 324 remainder 1

So, 7777 hours is equal to 324 days and 1 hour.

Finally, we can add 324 days and 1 hour to the current time in Washington, D.C.:

10:00 a.m. on March 1 + 324 days and 1 hour = 11:00 a.m. on January 20 of the following year.

Therefore, 7777 hours later in Washington, D.C., would be 11:00 a.m. on January 20 of the following year.

f(x) = x² and g(x) = 3(x + 1)² have the same minimum y-value and axis of symmetry, but they have different y-values at x = -2.

We have the function:

f(x) = x² and g(x) = 3(x + 1)² are both quadratic functions.

1. Minimum y-value:

For f(x) = x², the minimum y-value occurs at the vertex of the parabola, which is at (0, 0). The minimum y-value is 0.

For g(x) = 3(x + 1)², the minimum y-value occurs at the vertex of the parabola, which is at (-1, 0). The minimum y-value is also 0.

Therefore, both functions have the same minimum y-value.

2. Axis of symmetry:

For f(x) = x², the axis of symmetry is the vertical line that passes through the vertex of the parabola, which is x = 0.

For g(x) = 3(x + 1)², the axis of symmetry is also the vertical line that passes through the vertex of the parabola, which is x = -1.

Therefore, both functions have different equations but share the same axis of symmetry.

3. Y-value at x = -2:

For f(x) = x², the y-value at x = -2 is f(-2) = (-2)² = 4.

For g(x) = 3(x + 1)², the y-value at x = -2 is g(-2) = 3(-2 + 1)² = 3.

Therefore, the two functions have different y-values at x = -2.

Step-by-step explanation:

Step-by-step explanation:

The total amount of money collected from the ticket sales is:

$5/ticket x 3000 tickets = $15,000

The expected value for a person that buys a ticket can be calculated by adding up the probabilities of winning each prize multiplied by the amount of money for each prize:

E(X) = (1/3000) x $500 + (1/3000) x $250 + (1/3000) x $125 + (1/3000) x $50 - (2996/3000) x $5

E(X) = $0.1666667 + $0.0833333 + $0.0416667 + $0.0166667 - $4.9833333

E(X) = -$4.65

Therefore, the expected value for a person that buys a ticket is -$4.65, which means that on average, a person can expect to lose $4.65 for every ticket they buy.

1/3000 tickets will be worth $125.

1/3000 tickets will be worth $50.

The remaining 2996/3000 tickets will be worth $0. (Nobody else wins.)

So (1/3000)x500 + (1/3000)x250 + (1/3000)x125 + (1/3000)x50 + (2996/3000)x0 = $0.31.

The length of the flat-screen television is approximately 40.01 inches.

Let's assume that the height of the flat-screen television is "h" inches.

From the problem statement, we know that the length of the screen is 175% of its height.

Mathematically, we can write:

Length = 1.75 x Height

We can substitute the value of "h" in this equation to find the length of the screen:

Length = 1.75 x h

Now, we also know that the diagonal length of the screen is 40 inches. Using the Pythagorean, we can write:

(Length)² + (Height)² = (Diagonal)²

Substituting the values we have, we get:

(1.75h)² + h² = (40)²

Expanding and simplifying:

3.0625h² = 1600

Dividing both sides by 3.0625:

h² = 522.24

Taking the square root of both sides (and ignoring the negative root since we're dealing with lengths):

h = 22.86 inches

Now we can use the equation we derived earlier to find the length:

Length = 1.75 x h

Length = 1.75 x 22.86

Length = 40.01 inches (rounded to two decimal places)

When a scalar quantities is multiplied by a matrix of size 9x10, the resulting matrix will also be of size 9x10.

If we perform the matrix computation cM, where c is a scalar and M is a matrix of size 9x10, the resulting matrix cM will also be of size 9x10.

This is because when we multiply a scalar by a matrix, each element in the matrix is multiplied by the scalar.

Therefore, the resulting matrix has the same dimensions as the original matrix.

To see why this is the case, consider a single element in the resulting matrix cM. Let's say the element is located at row i and column j.

Then, it is given by cM[i,j] = c*M[i,j]. Since M[i,j] is just a single element in the original matrix, multiplying it by the scalar c produces a new scalar.

Therefore, cM[i,j] is also a single element in the resulting matrix cM.

Since each element in the original matrix M is multiplied by the scalar c, the resulting matrix cM will have the same dimensions as the original matrix, i.e., 9x10.

Answer:

We can use the formula for compound interest to solve this problem. The formula is:

A = P * (1 + r/n)^(n*t)

where:

A = the amount of money after t years

P = the principal amount (the initial investment)

r = the annual interest rate (as a decimal)

n = the number of times the interest is compounded per year

t = the number of years

In this case, P = $5000, r = 0.03, n = 12 (since the interest is compounded monthly), and t = 10. Plugging these values into the formula, we get:

A = 5000 * (1 + 0.03/12)^(12*10)

A = 5000 * (1.0025)^120

A ≈ $6,621.36

So the investment will be worth approximately $6,621.36 after 10 years.
