Is it true that when we multiply a number by 3, we get the same value as if we added 6 to that number.

Answer:

Set theory is the branch of mathematical logic that studies sets, which can be informally described as collections of objects. Although objects of any kind can be collected into a set, set theory, as a branch of mathematics, is mostly concerned with those that are relevant to mathematics as a whole.

Step-by-step explanation:

A character’s direct speech in a literary text is called as dialogue, so option 2 is correct.

In a literary text, a character's direct speech is referred to as "dialogue."

Dialogue is a literary device that involves a conversation between two or more characters.

It is the written representation of the spoken words between characters in the story.

Dialogue allows readers to understand the interactions, emotions, thoughts, and personalities of the characters through their words and interactions with each other.

Hence, a character’s direct speech in a literary text is called as dialogue, option 2 is correct.

Answer:

Part A) $202.50=9

Part B) $292.50=11

Step-by-step explanation:

Part A) y is the total cost, x is the total number of students. Therefore, y=x.

Which makes $202.50=9

Part B) since $202.50= 9 students,

1 student= $202.50÷9 = $22.50

Since 4 students joined,

4 students= $22.5 × 4= $90.00

4+9= 11 students

So 11 students= $202.50+$90.00 =$292.50

the total cost will now be $292.50

Answer:

If h > 0, then the graph of y = f (x – h) is a translation of h units to the RIGHT of the graph of the parent function. If h<0,then the graph of y=f(x–h) is a translation of |h| units to the LEFT of the graph of parent function

Answer:

135°

Step-by-step explanation:

In a hexagon, sum of all angles = 720

x + x + x + x + 90 + 90 = 720

4x + 180 = 720

4x = 720 - 180

4x = 540

x = 135°

Answer: 3 & 1/3

whole part = 3

fractional part = 1/3

=======================================================

Work Shown:

4/6 = x/5

4*5 = 6*x

20 = 6x

6x = 20

x = 20/6

x = (18+2)/6

x = (18/6) + (2/6)

x = 3 + (1/3)

x = 3 & 1/3

Side note: The first equation mentioned is only valid when we have parallel lines like this. This in turn leads to similar triangles and helps set up the ratio.

Calculator Use

This online calculator will calculate the various properties of a right circular cone given any 2 known variables. The term "circular" clarifies this shape as a pyramid with a circular cross section. The term "right" means that the vertex of the cone is centered above the base. Using the term "cone" by itself often commonly means a right circular cone.

Units: Note that units are shown for convenience but do not affect the calculations. The units are in place to give an indication of the order of the results such as ft, ft2 or ft3. For example, if you are starting with mm and you know r and h in mm, your calculations will result with s in mm, V in mm3, L in mm2, B in mm2 and A in mm2.

Below are the standard formulas for a cone. Calculations are based on algebraic manipulation of these standard formulas.

Circular Cone Formulas in terms of radius r and height h:

Volume of a cone:

V = (1/3)πr2h

Slant height of a cone:

s = √(r2 + h2)

Lateral surface area of a cone:

L = πrs = πr√(r2 + h2)

Base surface area of a cone (a circle):

B = πr2

Total surface area of a cone:

A = L + B = πrs + πr2 = πr(s + r) = πr(r + √(r2 + h2))

Circular Cone Calculations:

Use the following additional formulas along with the formulas above.

Given radius and height calculate the slant height, volume, lateral surface area and total surface area.

Given r, h find s, V, L, A

use the formulas above

Given radius and slant height calculate the height, volume, lateral surface area and total surface area.

h = (3 * v) / (πr2)

Given radius and lateral surface area calculate the height, slant height, volume and total surface area.

Given r, L find h, s, V, A

s = L / (πr)

h = √(s2 - r2)

Given radius and total surface area calculate the height, slant height, volume and lateral surface area.

Given r, A find h, s, V, L

s = [A - (πr2)] / (πr)

h = √(s2 - r2)

Given height and slant height calculate the radius, volume, lateral surface area and total surface area.

Given h, s find r, V, L, A

r = √(s2 - h2)

Answer:

x = 8.45

Step-by-step explanation:

5.4 + 0.2x = 7.09

Subtract 5.4 from both sides to leave 0.2x alone

0.2x = 1.69

Divide by 0.2 on both sides to isolate x

x = 1.69/0.2

x = 8.45

Answer:

x = -4

Step-by-step explanation:

2(x - 4) = 6x + 8

2x - 8 = 6x + 8

-4x - 8 = 8

-4x = 16

x = -4

Answer:

x = - 5.33

Step-by-step explanation:

2(x - 4) = 6x + 8                  Remove the brackets

2x - 8 = 5x + 8                    Subtract 2x from both sides

2x-2x - 8 = 5x - 2x + 8       Combine

- 8 = 3x + 8                         Subtract 8 from both sides

-8 - 8 = 3x + 8 - 8                Combine

- 16 = 3x                              Divide by 3

-16/3 = 3x/3

-5.33 = x

Step-by-step explanation:

5x + 3y ≥ -3

5x ≥ -3

x ≥ -3/5

5x + 3y ≥ -3

3y ≥ -3

y ≥ -3/3

y ≥ -1

Solution

x ≥ -3/5 and y ≥ -1

Answer:

x=-2

Step-by-step explanation:

first, remove the parenthesis.

3x-2x+1=7x-3+5x-x+24

collect like terms

x+1=11x+21

subtract x from both sides

1=10x+21

subtract 21 from both sides

-20=10x

divide both sides by 10

-2=x
