After the hole is cut, 248  square feet of blue feet of blue surface remain.

What is the surface area of the given cube?

The formula for surface area is equal to six times of square of the length of the sides of the cube. It is represented by 6a², where a is the side length of the cube. It is basically the total surface area.

We have given,

the cube of side length 6 ft,

the shape of a 2-by-4-by-6-foot rectangular prism is cut out of the cube,

to find: After the hole is cut, how many square feet of blue feet of blue surface remain?

area of an original cube is:

= 8 * 6 * 6

= 288 ft²

the area of the cube, after the hole, is cut.

remaining area = original cube area - 2 * 4 *4

= 288 -  32 ft²

= 248 ft²

Hence, After the hole is cut, 248  square feet of blue feet of blue surface remain.

Variables:  A = Adult tickets, C = Children tickets, S = Senior tickets

Expression for number of adult tickets sold: A = 15 + 3C

Expression for number of children's tickets sold: C = S/3

Let's define our variables:

A = Adult tickets

C = Children tickets

S = Senior tickets

We know that Joey sold 15 more adult tickets than children tickets. This means that the number of adult tickets (A) is 15 more than the number of children tickets (C). We can write this as an expression: A = 15 + C

We also know that Joey sold 3 times as many senior tickets as children tickets. This means that the number of senior tickets (S) is 3 times the number of children tickets (C). We can write this as an expression: S = 3C

Now, we can combine these two expressions to solve for the number of adult tickets sold. We can substitute the expression for S (3C) into the expression for A (15 + C) and solve for C.

Substituting 3C for S in A = 15 + C, we get: A = 15 + 3C

This expression tells us that the number of adult tickets sold (A) is equal to 15 plus 3 times the number of children tickets sold (C).

To solve for the number of children tickets sold (C), we can use the expression for S (3C). We can divide both sides of the equation by 3 to solve for C.

Dividing both sides by 3, we get: C = S/3

This expression tells us that the number of children tickets sold (C) is equal to the number of senior tickets sold (S) divided by 3.

An expression that represents the total area of Meiling's new deck is  4.3x + 29.67.

A quadrilateral with parallel sides that are equal to one another and four equal vertices is known as a rectangle.

Given:
An architect plans to build an extension to Meiling's rectangular deck.

Let x represent the increase, in meters, of her deck's length.

The expression 4.3(x+ 6.9) represents the area of the deck,

Yes, we can make the rectangle has sides of length n and n, and all four vertices have the same color

A rectangle is a two-dimensional shape with four sides, two of which are parallel and equal in length, and the other two sides are also parallel and equal in length.

In this case, the objects are the points in the plane with integer coordinates, and the available spaces are the six colors.

Since there are an infinite number of points with integer coordinates and only six colors, it follows that there must be a color that appears at the vertices of a rectangle.

In other words, we can color the points in a manner such that there will be a rectangle in which all four vertices are the same color. This is because, if we divide the points into six different regions, there must be at least one region that contains more points than the others.

When we look for a rectangle, we look for two points in this region that are the farthest apart from each other. The rectangle that connects these two points will have all four vertices the same color.

In conclusion, we can make the statement stronger by limiting the size of the purported monochromatic rectangle.

Answer:a=275 b =525

Step-by-step explanation:

Hi there, here's your answer:

Given:

a and b are integers

a + b = 800 ....(i)

b = a + 250

Putting value of b in (i)

a + (a + 250) = 800

2a + 250 = 800

2a = 800 - 250

Or

2a = 550

Therefore, a = [tex]\frac{550}{2}[/tex] = 275

Since b is 250 greater than a,

b = 250 + 275 = 525

The height of ball which is droped from 2m and rises to 75% after third bounce is equals to the 0.843 meters.

If an object is thrown from high and has a bouncing feature, each bouncing is less than the initial height until it stops. Each bounce reduces the growth rate until it reaches zero. In order to calculate the height of each bounce, so we can estimate what percentage the object will reach after each bounce. If we get the percentage of each bounce, we can easily determine the height of each bounce. We have, a ball is droped from 2 meters and bounce up to 75%. That is height of first bounce is determined by using percentage, height is 2 m × 75% = 2 m×0.75 = 1.5 m

In second bounce, height is 1.5 m × 75%

= 1.5 m×0.75 = 1.12 m

In third bounce, 1.12 m× 75%

= 1.12 m×0.75 = 0.843 m

So, the sequence is:

7, 4. 2, 2. 52, 1. 512, 0.9072,  0.54432,  0.326592

A geometric sequence is a sequence in which each term is found by multiplying the preceding term by the same value. Its general term is. a n= a 1 r n – 1. The value r is called the common ratio. It is found by taking any term in the sequence and dividing it by its preceding term.

The sequence is:

7, 4. 2, 2. 52, 1. 512,.

We have to find the next three terms.

To find r divide the 2nd term by the first:

4.2/7 = 0.6

To check if this is the same ratio for each number divide it by the ratio to get the number before it:

2.52/4.2 = 0.6

1.512/ 2.52 = 0.6

To find the next three terms multiply the last number by the ratio then repeat

(1.512)(0.6) = 0.9072

If the tax rate at this restaurant is 9. 5% and some other person’s sales tax is $1. 61 then their subtotal is $18.56

Here, some other person’s sales tax is $1. 61

Let us assume that for the amount of 'p' dollars, the sales tax is  is $1. 61

Here, the tax rate at this restaurant is 9. 5%

This means, 9.5 percent of m dollars is $1.61

m × (9.5 / 100) = 1.61

m × 9.5 = 1.61 × 100

m × 9.5 = 161

The number of units produced does not affect net operating income when using absorption costing.

All production expenses, including direct materials, direct labour, and both variable and fixed overhead costs, are included in the cost of each unit produced in absorption costing. This means that as more units are manufactured, the total manufacturing cost is distributed over a greater number of units, resulting in a reduced cost per unit.

Variable costing, on the other hand, includes only variable production expenses, such as direct materials, direct labor, and variable overhead costs, in the cost of each unit produced. Fixed manufacturing overhead costs are considered period expenses and are not included in the product cost.

Answer:

Step-by-step explanation:

Answer:

1 - cos² 15° - cos² 75° can be simplified as follows:

Using the identity cos² x = 1 - sin² x, we can write the expression as:

1 - (1 - sin² 15°) - (1 - sin² 75°)

= sin² 15° + sin² 75° - 1

Using the identity sin 2x = 2sin x cos x, we can write sin 15° and sin 75° in terms of sin 30° and sin 45°:

sin 15° = sin (30° - 15°) = (1/2) * sin 30°

sin 75° = sin (45° + 30°) = sin 45° + sin 30°

Substituting these values in the above expression, we get:

sin² 15° + sin² 75° = (1/4) * sin² 30° + sin² 45° + sin 30° * sin 45°

= (1/4) * (2 * (1/2)²) + (2 * (1/2) * (1/2)) + (1/2) * (1/2)

= (1/4) + 1/2 + 1/4 = 1

So, 1 - cos² 15° - cos² 75° = sin² 15° + sin² 75° - 1 = 1 - 1 = 0.

After 7 years, the balance of the savings account will be $1069.39.

An account balance is the amount of money in a financial repository at any particular time, such as a savings or checking account. The account balance is always the net amount after all debits and credits are subtracted.

The formula to calculate the balance after t years is A = P(1 + r/n)^(nt), where A is the balance (final amount), P is the principal (starting amount), r is the interest rate expressed as a decimal, n is the number of times per year that the interest is compounded, and t is the time in years.

In this case, P = 700.00, r = 0.07, n = 1 (since the interest is compounded annually), and t = 7. Plugging these values into the formula, we get:

A = 700.00 * (1 + 0.07/1)^(1 * 7)

A = 700.00 * (1.07)^7

A = 700.00 * 1.527674

A = $1069.39
