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

Answer: OPTION A

Step-by-step explanation:

To simplify the expression you must multiply the numerator and the denominator of the expression by √3.

As all the square roots have equal index, you can multiply the radicands, which are the numbers inside of the sqaures roots.

You also must keep on mind that:

[tex](\sqrt[n]{a})^n=a[/tex]

Therefore, you obtain:

[tex]\frac{6\sqrt{2}*\sqrt{3}}{\sqrt{3}*\sqrt{3}}=\frac{6\sqrt[]{6}}{3}=\frac{2\sqrt[]{6}}{3}[/tex]

Answer:

The correct answer is option B.  2√6

Step-by-step explanation:

It is given that an expression, 6√2/√3

To simplify the expression

6√2/√3

Multiplying numerator and denominator with √3

6√2/√3 = (6√2 x √3)/(√3 x √3)

  = [ 6 x √(2x3)]/3)                    (√2 x √3 = √(2 x 3)

  = 6√6/3  

  = 2√6

Therefore the simplified form of given expression 6√2/√3 is 2√6.

The correct answer is option B. 2√6

-4 < -12 would be my answer, just from looking at it. If you write it out on a number line, the number -4 is higher than -12. The higher the negative number, the lower it is on the line. So, -4 is greater than -12, not lower than.

The comparison which is not correct is Option (D) -4<-12

The inequality, greater than or lesser than between two numbers indicate that whether one number is greater than the other number or less than the other number. The inequality is represented by ">" and "<".

In number system, when comparing two numbers less than zero then the magnitude of smaller negative number is always greater than the magnitude of bigger negative number. Or in other words it is opposite to the positive number system .

For example,  -10<-4  or  -2<-1

Thus the comparison which is incorrect is Option (D)  -4 < -12.

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

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.

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]

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.

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

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%

[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:

  yes, -6

Step-by-step explanation:

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

Answer:

Yes, it does.

Step-by-step explanation:

Every regular shaped figure will have rotational symmetry, since they are built with identical segments all around.

To find the answer, ask yourself « If I rotate the shape, is there a time where I’ll find the exact same shape again with a different angle? »

So, a square has rotational symmetry, but not a rectangle.

A equilateral triangle has rotational symmetry, but not any other type of triangle.
