Answer:

n=12

Step-by-step explanation:

13 less than 9 times a number: 13 less than 9n, 9n-13

11 more than 7 times a number: 11 more than 7n, 7n+11

9n-13=7n+11

2n=24

n=12

Answer:

1000

Step-by-step explanation:

I guess, something went wrong with the text up there.

I assume it should say 2cm×2cm×2cm cubes. right ? because a cube has 3 dimensions, not just 2.

otherwise an infinitely large number of "just squares" would fit into the box ...

so, the box is

1m×20cm×4cm = 100cm×20cm×4cm = 8000 cm³

a single cube would be

2cm×2cm×2cm = 8 cm³

therefore,

8000 / 8 = 1000 cubes can be packed into that box, since the dimensions of the box in relation to the dimensions of the cubes do not force to have some empty left over space. the box can be packed tightly.

Answer:

x = 8[tex]\sqrt{2}[/tex]

Step-by-step explanation:

The triangle is isosceles with legs congruent, both x

Using Pythagoras identity in the right triangle

x² + x² = 16²

2x² = 256 ( divide both sides by 2 )

x² = 128 ( take the square root of both sides )

x = [tex]\sqrt{128}[/tex] = [tex]\sqrt{64(2)}[/tex] = [tex]\sqrt{64}[/tex] × [tex]\sqrt{2}[/tex] = 8[tex]\sqrt{2}[/tex]

Step-by-step explanation:

[tex]v = \frac{\pi r {}^{2}h }{3} [/tex]

[tex]3v = \pi {r}^{2} h[/tex]

[tex] \frac{3v}{\pi h} = {r}^{2} [/tex]

[tex] \sqrt{ \frac{3v}{\pi h} } = r[/tex]

Answer:

196 in/cm/m²

Step-by-step explanation:

Given that the scale factor is a : b , then the area factor is a² : b² Here the scale factor is 1 : 7 , thus area scale factor is 1² : 7² = 1 : 49 That is the area of the dilated square is 49 times the original square. area of dilated square = 4 × 49 = 196 in/cm/m²

Answer:

A) Net A (see explanation)

B) AB = 3 in. | BC = 5 in. | CD = 7.2 in.

C) SA = 98.4 in²

Step-by-step explanation:

Part A

Net A is the correct net for the prism. If you look at the way the folds are, the flaps on the top and bottom would fold up to make the side of the prism. On net B, the flaps wouldn’t fit the shape correctly.

Part B

AB = This is the height of the prism.

= 3 in.

BC = This is the slant on the front of the prism.

= 5 in.

CD = This is the length of the prism.

= 7.2 in.

Part C

* First we’ll solve for the two triangles. They are the same shape and size, so we just need to solve one then duplicate it.

One triangle:

A = 1/2bh

= 1/2 (4) (3)

= 6 in²

Back rectangle:

A = bh

= 7.2 (3)

= 21.6 in²

Front rectangle:

A = bh

= 7.2 (5)

= 36 in²

Bottom rectangle:

A = bh

= 7.2 (4)

= 28.8 in²

Total:

A = 6 + 6 + 21.6 + 36 + 28.8

= 98.4 in²

Answer: Distance = √17

Concept:

Here, we need to know the concept of the distance formula.    

The distance formula is the formula, which is used to find the distance between any two points.

Distance Formula = [tex]Distance=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

If you are still confused, please refer to the attachment below for a clear version of the formula.

Solve:

Given information

(x₁, y₁) = (-2, 5)

(x₂, y₂) = (2, 6)

Given formula

[tex]Distance=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

Substitute values into the formula

[tex]Distance=\sqrt{(2+2)^2+(6-5)^2}[/tex]

Simplify value in the parentheses

[tex]Distance=\sqrt{(4)^2+(1)^2}[/tex]

Simplify exponents

[tex]Distance=\sqrt{16+1}[/tex]

Simplify by addition in the square root

[tex]\boxed{Distance=\sqrt{17}}[/tex]

Step-by-step explanation:

Circumference = 76cm

Circumference = 2(π)(r)

r -> radius

=> 2(π)(r) = 76

=> (π)(r) = 76/2

=> (π)(r) = 38

=> 3r = 38

=> r = 38/3

=> r = 13cm (Approx.)

Diameter = 2r = 2(13) = 26cm

Area = π(r)^2

        = 3(13)^2

        = 3(169)

        = 507 cm^2

Answer

d=25.34cm

a=160.53cm

cf=12.67cm

Step-by-step explanation:

circumference=cf

diameter=d

radius=r

area=a

d=2r

=2×12.67cm

=25.34cm

cf=2πr

76cm=2(3)r

76cm=3r

2

38cm=r

3

r=12.66^cm

r=12.67cm

find the area

a=πr^2

a=12.67×12.67πcm

a=160.53πcm(it is near to this)

Answer:

60

Step-by-step explanation:

let X be the total number of students.

48÷x *100 = 80

4800= 80x

X = 60 students

the negative will shift the graph right, so x = 1/2

the negative 2 will shift the graph down, so y = -2

Thus, the vertex is (1/2, -2)

Answer:

180 children and 175 adults

Step-by-step explanation:

Let it be that the amount of children who visited the park that day was x, the rest was adults. It means the quantity of adults equals 355-x.

The payment from the children is 1.5*x (because each children payed 1.5 dollars, the amount of money from children is the fee from one child multiplied by the quantity of children). The money earned by the park's owners from adults are equal to the fee from one adult multiplied by the quantity  4* (355-x)= 1420 -4x

If we add the money from chilren and adults we get the summary profit of park (it is equal to 970 dollars)

1.5x+ 1420-4x= 970

1420-2.5x= 970

x=180- children

355-180=175adults

The expression that represents the perimeter P as a function of x is 14x + 14

The perimeter can simply be defined as the part or portion surrounding a shape or boundary. The formula for calculating the perimeter of the rectangular yard is expressed as:

The perimeter of the rectangular yard = 2(L+W) where:

L is the length

W is the width

Given the following parameters

Length = 5x + 2

Width = 2x

Substitute the given parameters into the formula above:

Perimeter = 2(5x+2+2x)

Perimeter = 2(7x + 2)

Perimeter = 14x + 4

Hence the expression that represents the perimeter P as a function of x is 14x + 14

[tex]2x^3-9x^2+7x+6[/tex]

Step-by-step explanation:

The standard form of a polynomial is a method of writing a polynomial such that the terms are organized by degrees. In essence, the first term, or the left-most term has the highest degree or largest exponent. The right-most term or last term has the lowest degree or smallest exponent. One is given an expression in factored form. Distribute, multiply every term by another in the parenthesis, then simplify. Repeat this process until there are no more factored terms. Finally, rewrite the expression in standard form.

[tex](2x+1)(x-3)(x-2)[/tex]

Distribute,

[tex](2x+1)(x-3)(x-2)[/tex]

[tex]((2x)(x)+(-3)(2x)+(1)(x)+(1)(-3))(x-2)[/tex]

Simplify,

[tex]((2x)(x)+(-3)(2x)+(1)(x)+(1)(-3))(x-2)[/tex]

[tex](2x^2-6x+x-3)(x-2)[/tex]

[tex](2x^2-5x-3)(x-2)[/tex]

Distribute,

[tex](2x^2-5x-3)(x-2)[/tex]

[tex](2x^2)(x)+(-5x)(x)+(-3)(x)+(-2)(2x^2)+(-2)(-5x)+(-3)(-2)[/tex]

Simplify,

[tex](2x^2)(x)+(-5x)(x)+(-3)(x)+(-2)(2x^2)+(-2)(-5x)+(-3)(-2)[/tex]

[tex]2x^3-5x^2-3x-4x^2+10x+6[/tex]

[tex]2x^3-9x^2+7x+6[/tex]

This polynomial is already in standard form, thus there is no need to reorganize it. The leading term or the left-most term has the highest degree, three, the succeeding terms are in respective order of decreasing exponents.

ANSWER: The glass window will cost $252.00 for window replacement.

EXPLANATION:

The area of a square is given by the formula:

s^2

where s is the side length.

If we were to replace the glass window, and it will cost $7.00 per square foot, the total price will be:

FIND AREA OF THE GLASS WINDOW:

6^2 = 36 square feet

$7 per square foot so:

36 x 7 = 252

Therefore it will cost $252.00 to replace the glass window.
