Which system of inequalities is shown?

Answer:

[tex]n[/tex].

Step-by-step explanation:

Assuming that [tex]n \in Z^{+}[/tex], then all number less than [tex]n+1[/tex] are

[tex]n+1-1=n[/tex]

Notice that the "plus one" indicates that the whole number shown by the expression [tex]n+1[/tex] indicates a whole number greater than [tex]n\\[/tex] by one unit. So, we just subtract one whole unit to achive a number less than the given expression.

Therefore, the answer is [tex]n[/tex].

Answer:

10

Step-by-step explanation:

The distance between the points  (-3, -6) and (3, 2) is  10 units.

The distance formula between two points (x₁, y₁) and (x₂, y₂) is given by,

D = [tex]\sqrt{(x_2 - x_1)^2 + (y_2 - y_1_)^2[/tex].

Given, We have to determine the distance between the points (- 3, - 6) and (3, 2).

Let, (x₁, y₁) is (- 3, - 6) and (x₂, y₂) is (3, 2).

Therefore,

D = [tex]\sqrt{(3 + 3)^2 + (2 + 6)^2[/tex].

D = [tex]\sqrt{(6)^2 + (8)^2[/tex].

D = [tex]\sqrt{(36 + 64)[/tex].

D = [tex]\sqrt{100}[/tex].

D = 10 units.

Step-by-step explanation:

It is mandatory (required) to use " ^ " for exponentiation:

(3x – 5)^2 = 4

Taking the square root of both sides, we get

3x - 5 = ±2, or

3x = 5 ±2, or

(a) 3x = 7 => x = 7/3, and

(b) 3x = 3, or x = 1

Answer:

392

Step-by-step explanation:

I got it correct! :)

The surface area of the design is 392 square inches.

The correct option is B.

A cuboid is a solid in three dimensions with six rectangular faces, eight vertices, and twelve edges. Three dimensions, including length, breadth, and height, define a cuboid. A cuboid with integer edges is referred described as being perfect.

Given:

The shape is a cuboid.

The surface area of the cuboid,

= 2lw+2lh+2hw,

where l is the length, w is the width and h is the height.

The height of the upper cuboid,

= 10-4 = 6 inches.

The surface area of the upper cuboid,

= 2lw+2lh+2hw

= 2(36) + 2(36) - 2(36)

= 144 square inches.

The surface area of the lower cuboid,

= 2lw+2lh+2hw

= 2(40) + 2(24) + 2(60)

= 248 square inches.

The total surface area,

= 392 square inches.

Therefore, the surface area of the design is 392 square inches.

Answer:

Perimeter = 55.1 ft

area = 236.625 ft2

Step-by-step explanation:

radius = 15 / 2 = 7.5

Perimeter = perimeter of 2 half circle + 4+4

                = perimeter of 1 circle +4 +4

                = 2*7.5* pi + 4 + 4 = 55.1 ft

area = area of 2 half circle + area of 1 rectangle

        = area of 1 circle + area of 1 rectangle

        = pi *7.5*7.5 +4*15

        = 236.625 ft2

Answer:

x=9.5

Step-by-step explanation:

In order to find the answer, we know that 6x + 4x - 5 = 90

Next we want to combine like terms: 10x - 5 = 90.

Now we have to add 5 to 90 in order to get x on its own.  10x = 95

Now solve for x by dividing 95 by 10: x=9.5

Answer:

x = 7°

<GDH = 112°

<FDH = 192°

<FDE = 135°

Step-by-step explanation:

If DE bisects <GDH this means that <GDE = <EDH

Given <GDE = (8x+1)° and <EDH = (6x+15)° then;

8x+1 = 6x+15

8x-6x = 15-1

2x = 14

x = 7°

Since <GDH = <GDE + <EDH

<GDH = 8x-1+6x+15

<GDH = 14x+14

<GDH = 14(7)+14

<GDH = 98+14

<GDH = 112°

For <FDH,

Note that sum of angle on a straight line is 180°

<FDH = <FDG + <GDE + <EDH

<FDH = <FDG + <GDH

<FDG = 180-(43+8x+1)

<FDG = 180-44-8x = 136-8x

<FDH = 136-8x+112

<FDH = 248-8x

<FDH = 248-8(7)

<FDH = 248-56

<FDH = 192°

For <FDE;

<FDE = <FDG + <GDE

<FDE = 136-8x+8x-1

<FDE = 135°

Answer:

4

Step-by-step explanation:

You can cross multiply.

first i would simplify x/12=3/9 to x/12=1/3

so then it would be equal to x*3=1*12

then i would simplify it to 3x=12

then you solve for x and i would get 4

Answer:

x = 4

Step-by-step explanation:

[tex]\frac{x}{12} =\frac{3}{9} \\[/tex]

Simplify [tex]\frac{3}{9} = \frac{1}{3} \\[/tex]

What is a third of 12?

4

x = 4

The equation would be x² + x = 42 which represents "the sum of a number and its square is 42". The correct answer would be an option (A).

Algebra is the analysis of mathematical representations, while logic is the manipulation of those symbols.

We have been given that the sum of a number and its square is 42.

Let's assume the required number would be x

According to the given question, translate the phrase into an algebraic form:

The number = x

The number's square = x²

Thus, the sum of a number and its square is 42 will be as:

⇒ number + number's square = 42

⇒ x +  x² = 42

Therefore, the equation would be x² + x = 42 which represents "the sum of a number and its square is 42".

Hence, the correct answer would be option (A).

Step-by-step explanation:

1. We know that the 2 lines are not parallel. If they were, it would be marked on the graph. Therefore, corresponding angles (5 and 6 in this case) are not equal.

2. Angles 1 and 2 are corresponding angles, and because the 2 lines are parallel, they must be equal. Therefore, ∠1 = ∠2 = 60°.
