Answer: [tex]\frac{5}{8}[/tex] yard.

Step-by-step explanation:

You have the following information given in the problem:

- You have 3/4 yard of felt.

- You used 1/8 yard,

Therefore, to find the fraction of a yard of felt that you have left over (which you can call x), you only need to subtract 3/4yard and 1/8 yard, as you can see below:

[tex]x=\frac{3}{4}yard-\frac{1}{8}yard\\\\x=\frac{5}{8}yard[/tex]

Answer:

[tex]Area = (30 + x)(20 + x)[/tex]

Step-by-step explanation:

By definition, the area of a rectangle is the product of its length multiplied by its width.

Initially the dog run has a length of 30 ft long and 20 ft wide.

If you want to expand the track, increase the length of each side by a factor x. So, the dimensions of the expanded dog run will be:

[tex]Length = 30 + x\\Width = 20 + x[/tex]

Then, the area is:

[tex]Area = Length * Width[/tex]

[tex]Area = (30 + x)(20 + x)[/tex]

The total area of an expanded rectangular dog run, after increasing each side by the same amount x, is calculated using the formula A = (l + 2x)(w + 2x), where l is the original length and w is the original width. The new area after expansion is 4x^2 + 100x + 600 square feet.

The student is asking how to calculate the total area of an expanded rectangular dog run after increasing each side by the same amount, x. To solve this, we can use the formula A = lw, where A is the area, l is the length, and w is the width of the rectangle. In the original dimensions, the dog run has a length of 30 ft and a width of 20 ft. After expanding, the new dimensions will be (30 + 2x) ft for the length and (20 + 2x) ft for the width, since each side is increased by x on each end.

Expanded Dog Run Area Calculation:

First, we write out the new dimensions:

Then, we calculate the new area:

A = (30 + 2x)(20 + 2x)

A = 600 + 60x + 40x + 4x^2

A = 4x^2 + 100x + 600

The expanded area of the dog run will be 4x^2 + 100x + 600 square feet.

the answer to the question is multiplication

The given equation is :

[tex]24x^{3}y^{2} -4x^{2}y +84x^{4}[/tex]

Now taking [tex]4x^{2}[/tex] common from all the terms, we get

[tex]4x^{2} (6xy^{2} -y+21x^{2} )=0[/tex]

Writing the equation in standard form we get:

[tex]21x^{2} +6xy^{2} -y=0[/tex]

Now we will use the formula of quadratic equations to solve this,

[tex]x1,2 = \frac{-b+\sqrt{b^{2}-4ac }} {2a}[/tex] and

[tex]x1,2 = \frac{-b-\sqrt{b^{2}-4ac }} {2a}[/tex]

Now putting a = 21, b = 6y² and c = -y and solving the equations, we get

[tex]x=\frac{-6y^{2}+\sqrt{36y^{4}+84y }}{42}[/tex] and

[tex]x=\frac{-6y^{2}-\sqrt{36y^{4}+84y }}{42}[/tex]

Ivan walked  on the first day = 15 miles .

Ivan walked  on the second day = 25 miles .

Ivan walked in 2 days = 15 + 25 = 40 miles .

So, Ivan have left to walk  = 60 -40 = 20 miles .

Therefore , Ivan have left to walk  = 20 miles .

Answer:

3 m^2

Step-by-step explanation:

The shaded area = Area of Sector - Area of Triangle

First we find area of sector = [tex]\frac{\theta}{360}*\pi r^2[/tex]

We know the angle is 60° (vertical angles are equal) and the radius is 6, so we find the area of sector to be:

[tex]\frac{\theta}{360}*\pi r^2\\\frac{60}{360}*\pi (6)^2\\=18.85[/tex]

Secondly, we find area of triangle (isosceles) = [tex]\frac{1}{2}abSinC[/tex]

where

a and b are the two sides bordering the known angle, so a=b=6, and

C is the angle which is 60°

Now we find the area to be:

[tex]\frac{1}{2}(6)(6)Sin(60)\\=15.59[/tex]

Hence, area of shaded = [tex]18.85 - 15.59=3.26[/tex]

Rounding to nearest whole number, area of shaded region = 3m^2

Final answer:

The surface area covered by the banner is 27,000 square meters. The side length of a square with the same area would be approximately 164.3 meters.

Explanation:

The office building is a right rectangular prism with a height of 200m, a length of 60m, and a width of 40m. The upper quarter of each vertical face needs to be covered with a large banner.

To find the surface area covered by the banner, we need to calculate the surface area of each vertical face. The surface area of a rectangular prism is given by the formula 2lw + 2lh + 2wh. Since we need to cover the upper quarter of each face, we can consider only three quarters of the height, resulting in a formula of 2lw + (3/4)lh + 2wh.

Plugging in the given values, we get:

Surface area = 2(60)(40) + (3/4)(200)(60) + 2(40)(200)

Simplifying the expression, we get the surface area covered by the banner to be 27,000 square meters.

If we want to represent the area as a square with the same area, we can take the square root of the surface area. In this case, the side length of the square representing the area would be approximately 164.3 meters.

Adjacent terms have a common ratio of -6, so they comprise a geometric sequence.

Answer:

x^2 - 10x + 25 = 17

Step-by-step explanation:

Please use " ^ " to denote exponentation:

x^2 - 10x = -8

x^2 - 10x + 25 = 17

x^2 - 10x + 25 = -8

x^2 - 10x - 25 = -33

Begin with x^2 - 10x = -8.  Here's the process for completing the square:

1.  Take half of the coefficient of x and square the result:

    (1/2)(-10) = -5, and then (-5)^2 = + 25

2.  Add this 25 to the first two terms of x^2 - 10x = -8 and also to the      constant -8:    x^2 - 10x + 25 = -8 + 25, or     x^2 - 10x + 25 = 17

3.  Match this result to one of the given possible answers.  Turns out that the given possible answer matching our result is the first one:

x^2 - 10x + 25 = 17

Answer:

a) The volume of the dunking booth = 98 feet³

b) They will need 84 feet³ of water to fill 6/7 of dunking booth

Step-by-step explanation:

* Lets talk about the rectangular prism

- It has 6 rectangular faces each two opposite faces are congruent

- It has three dimensions Length, Width and Height

- Its volume = Length × Width × height

* In our problem the dunking booth is a rectangular prism

 with dimensions:

- Width = 3.5 ft

- Length = 3.5 ft

- Height = 8 ft

∴ Its volume = 3.5 × 3.5 × 8 = 98 feet³

a) The volume of the dunking booth = 98 feet³

* They want to fill 6/7 of the dunking booth with water

∴ The volume of the water will be 6/7 from the volume

   of the dunking booth

∵ The volume of the dunking booth = 98 feet³

∴ The volume of the water = 6/7 × 98 = 84 feet³

b) * They will need 84 feet³ of water

a) 98

b) 84

Oh that question

Parallel sides

Opposite sides are congruent

And diagonals bisect each other

A rectangle is a four-sided quadrilateral with four right angles, opposite sides are parallel and of equal length, and the area is the product of its base and height. Rectangles typically have a larger perimeter than a square with the same area and can form larger rectangles when equal rectangles are combined. The golden rectangle has sides in the golden ratio, considered aesthetically pleasing.

A rectangle is a geometrical figure with some specific properties. First, it is a quadrilateral, meaning it has four sides. A defining characteristic of a rectangle is that it has four right angles (90°). Due to this property, opposite sides of a rectangle are parallel and equal in length. The area of a rectangle can be calculated by multiplying its base (length) by its altitude (height). A square is a special type of rectangle where all four sides are of equal length.

In terms of perimeter, a rectangle has a larger perimeter compared to a square of the same area, because it will have two longer sides and two shorter sides, whereas a square has four sides of equal length. This also means that in geographic terms, a rectangle would represent a larger coastline if used to approximate a peninsula. When constructing a golden rectangle, which is a rectangle with aesthetically pleasing proportions found in nature and art, the ratio of the longer side to the shorter side is known as the golden ratio.

Another important fact about rectangles is that by placing equal rectangles together, we can form a larger rectangle with sides that simply are multiples of the corresponding sides of the original rectangles. This principle is used in various mathematical proofs and constructions.

[tex]\huge\text{B. $\boxed{x+(y-z)}$}[/tex]

First, let's take a look at the terms in the original expression. Since its just addition and subtraction, we can get rid of the parentheses, leaving behind just [tex]x+y-z[/tex].

As long as an answer is made up of a positive [tex]x[/tex], a positive [tex]y[/tex], and a negative [tex]z[/tex], its correct!

Removing the parentheses in choice A leaves us with [tex]z+x+y[/tex], which has a positive [tex]z[/tex] rather than a negative [tex]z[/tex], so it's incorrect.

Removing the parentheses in choice B on the other hand gives us [tex]x+y-z[/tex], which means it's the correct answer! This is a good example of the associative property of addition in action.

The correct expression that is equivalent is option B.  x +(y − z)

Let's simplify each expression to see if they are equivalent to (x + y) - z:

A. ( z + (x + y))

We can rearrange the terms:

z + (x + y) = (x + y) + z

This is not equivalent to (x + y) - z  because the terms are added in a different order.

B. (x + (y - z))

We can expand the expression:

[tex]\[ x + (y - z) = x + y - z \][/tex]

This expression is indeed equivalent to (x + y) - z because the terms are arranged in the same order and operations are consistent.

So, the correct answer is:

[tex]\[ \text{B. } x + (y - z) \][/tex]

Answer:

y = 6.4

Step-by-step explanation:

1.1 = 13.9 - 2y

-12.8 = -2y

6.4 = y

Answer:

y = 6.4

Step-by-step explanation:

Simplifying

1.1 = 13.9 + -2y

Solving

1.1 = 13.9 + -2y

Solving for variable 'y'.

Move all terms containing y to the left, all other terms to the right.

Add '2y' to each side of the equation.

1.1 + 2y = 13.9 + -2y + 2y

Combine like terms: -2y + 2y = 0

1.1 + 2y = 13.9 + 0

1.1 + 2y = 13.9

Add '-1.1' to each side of the equation.

1.1 + -1.1 + 2y = 13.9 + -1.1

Combine like terms: 1.1 + -1.1 = 0.0

0.0 + 2y = 13.9 + -1.1

2y = 13.9 + -1.1

Combine like terms: 13.9 + -1.1 = 12.8

2y = 12.8

Divide each side by '2'.

y = 6.4

Simplifying

y = 6.4

Step-by-step explanation:

There were a total of 435 people in the House. 9 were neither Republican nor Democratic. Divide 9/435. multiply that by 100

Answer:

The answer is C.

Step-by-step explanation:

In 1997 U.S. House of Representatives there were 222 Republicans, 204 Democrats, 2 Independents, and 7 undecided.

So total number in the House = 222 + 204 + 2 + 7

= 435

Total number who is neither Republican nor Democrat = 2 + 7

= 9

Percentage of the total is neither Republican nor Democrat

= 9 / 435 * 100%

= 2.1%

Answer:

V = 240 in ^3

SA = 2(lw+lh+wh)

SA = 236 in^2

Step-by-step explanation:

Volume = l*w*h where l=length, w= width and h =height

We know l=6, w=5 and h =8

V = 6*5*8

V = 240 in ^3

The formula for surface area of a rectangular prism is

SA = 2(lw+lh+wh)  where l=length, w= width and h =height

We know l=6, w=5 and h =8

Substituting into the equation

SA = 2(6*5+6*8+5*8)

     = 2 (30+48+40)

     =2(118)

     = 236 in ^2

Hey there!

Let’s turn everything into yards (instead of feet) so we can determine which is greater

To do this, all we have to do is divide 3 (that’s how many feet are in a yard) by 429 & 460 (these are the 2 lengths that are represented by feet)

429 ÷ 3 = 143

460 ÷ 3 = 153.333... (let’s round to 153)

Now, we determine which is greater:

150 yards > 143 yards

So, 150 yards is greater than 143 yards (or 429 feet)

130 yards < 153 yards

So, 130 yards is less than 153 yards (or 460 feet)

Hope this helps you!

God bless ❤️
