Answer:

x=3

Step-by-step explanation:

First distribute the 3!

3x+6+2x=21

Then, combine like terms.

5x+6=21

Move the 6 to the other side

5x=15

Divide each side by 5

x=3

Answer:

The estimated distance is 8.1cm.

The actual distance is 8.106cm.

Step-by-step explanation:

Given that the Pythogorean Theorem, c² = a² + b². Then substitute the following values into the formula :

[tex] {c}^{2} = {a}^{2} + {b}^{2} [/tex]

Let a = 5.1cm,

Let b = 6.3cm,

[tex] {c}^{2} = {5.1}^{2} + {6.3}^{2} [/tex]

[tex] {c}^{2} = 26.01 + 39.69[/tex]

[tex] {c}^{2} = 65.7[/tex]

[tex]c = \sqrt{65.7} [/tex]

[tex]c = 8.106cm \: (3d.p)[/tex]

Answer:

Both coordinates are negative

Answer:

The x-coordinate is negative, and the  y-coordinate is negative.

Step-by-step explanation:

It's a bite hard to explain it without a xy-plane. I don't want to upload it, so I will try to draw it:

            [tex]\left[\begin{array}{ccc}a&|&b\\-&-&>\\c&|&d\end{array}\right][/tex]

We have point [tex]a[/tex] in the coordinates [tex](-x, y)[/tex]

We have point [tex]b[/tex] in the coordinates [tex](x, y)[/tex]    

We have point [tex]c[/tex] in the coordinates [tex](-x, -y)[/tex]        

We have point [tex]d[/tex] in the coordinates [tex](x, -y)[/tex]

A point with a positive x-coordinate and a negative y-coordinate is reflected over the y-axis.

This point is [tex]d[/tex]. Once it is reflected over the y-axis, it turns to be point [tex]c[/tex].

Answer:

V 8 on 8 D

Step-by-step explanation

Answer:

a ) Surface Area ⇒ 222 cm^2, Volume ⇒ 180 cm^3

b ) Surface Area ⇒ 372 cm^2, Volume ⇒ 360 cm^3

c ) Surface Area Increase ⇒ ( About ) 67.56 %, Volume Increase ⇒ 100 %

Step-by-step explanation:

a ) Consider dividing the figure into parts, first solving for the area of the base, using the attachment below for guidance;

As you can see, in the picture I have made it so that the base is nested in a rectangle with dimensions 8 by 5. Calculating the area of this rectangle, subtracting the area of a square with dimensions 2 by 2 cm, we can derive the area of the base in a much quicker manner;

[tex]Area of Base - ( 8 cm * 5 cm ) - ( 2 cm* 2 cm ) = 40 square cm - 4 square cm = \\Solution; Base = 36 square cm[/tex]

Now let us imagine adding the another dimensions to this two dimensional base. That would make a 3 - d prism, with surface area equivalent to mini rectangles and squares with a common dimension being the length of the height; 5 cm

[tex]Area of 1 Square = 5 cm * 5 cm = 25 square cm,\\Area of 2 Square = 25 square cm,\\Area of 1 Rectangle = 3 cm * 5 cm = 15 square cm,\\Area of 2 Rectangle = 15 square cm,\\Area of 3 Rectangle = 2 cm * 5 cm = 10 square cm,\\Area of 4 Rectangle = 10 square cm,\\Area of 5 Rectangle = 10 square cm,\\Area of 6 Rectangle = 8 cm * 5 cm = 40 square cm\\Area of Base 2 = 36 square cm,\\\\Surface Area of Figure = 25 + 25 + 15 + 15 + 10 + 10 + 10 + 40 + 36 + 36 = 222 square cm\\Volume = 36 square cm * 5 cm = 180cubiccm[/tex]

b ) We have calculated the area of the base before, now let us solve for all the " mini shapes " given a new height of 10 cm;

[tex]Area of Rectangle 1 = 5 cm * 10 cm = 50 cm^2,\\Area of Rectangle 2 = 50 cm^2,\\Area of Rectangle 3 = 3 cm* 10 cm = 30 cm^2,\\Area of Rectangle 4 = 30 cm^2,\\Area of Rectangle 5 = 2 cm * 10 cm = 20 cm^2,\\Area of Rectangle 6 = 20 cm^2,\\Area of Rectangle 7 = 20 cm^2,\\Area of Rectangle 8 = 8 cm * 10 cm = 80 cm^2,\\\\Surface Area of Figure = 50 + 50 + 30 + 30 + 20 + 20 + 20 + 80 + 36 + 36 = 372 cm^2\\Volume of Figure = 36 cm^2 * 10 cm = 360 cubic cm[/tex]

c ) Solution; Increase of Surface Area ⇒ ( About ) 67.56 %, Increase of Volume ⇒ 100 %

The answer is (4,7)

The coordinates of the midpoint of the segment whose endpoints are A(2, 6) and B(6, 8) will be (4, 7).

Let C be the mid-point of the line segment AB.

A = (x₁, y₁)

B = (x₂, y₂)

C = (x, y)

Then the midpoint will be

x = (x₁ + x₂) / 2

y = (y₁ + y₂) / 2

AB has endpoints at A(2, 6) and B(6, 8). Then we have

(x₁, y₁) = (2, 6)

(x₂, y₂) = (6, 8)

Then the mid-point will be

x = (2 + 6) / 2

x = 8 / 2

x = 4

y = (6 + 8) / 2

y = 14/2

y = 7

Then the coordinates of the midpoint of the segment whose endpoints are A(2, 6) and B(6, 8) will be (4, 7).

Answer:

[tex]\frac{21.05}{0.2}=105.25[/tex]

Step-by-step explanation:

you have to do long division, but there is a number of steps, too many to put in here, but just check on calculator if you want to make sure

21.05 divided by 0.2 equals to 105.25

Division is one of the four basic operations of arithmetic, the ways that numbers are combined to make new numbers.

The process of dividing a number up into equal parts, and finding how many equal parts can be made.

Division is a process of splitting a specific amount into equal parts. For example, we can divide a group of 20 members into 4 groups of 5 members.

Given that, 21.05 divided by 0.2

So, 21.05 ÷ 0.2 = 21.05/0.2

Multiply by 100

= 21.05 x 100 / 0.2 x 100

= 2105/20

= 421/4

= 105.25

Hence, 21.05 divided by 0.2 equals to 105.25

The three correct ways to describe an angle with a measure of 13° are  it turns through 13 one degree angles. It turns through 13/360  of a circle and It is the same size as 13 one degree angles.

What is Angle?

An angle is defined as the figure, in which two rays meet at a common point called the vertex. The angle is denoted using the symbol “∠”.

We have been given an angle with a measure of 13°

Acute: An angle with a measure less than 90° is considered acute. 13° is an acute angle.

Straight: An angle with a measure of exactly 180° is considered straight. 13° is not a straight angle.

Obtuse: An angle with a measure greater than 90° and less than 180° is considered obtuse. 13° is not an obtuse angle.

13° measure means it turns through 13 one degree angles.

It turns through 13/360  of a circle

It is the same size as 13 one degree angles.

Hence, the three correct ways to describe an angle with a measure of 13° are  it turns through 13 one degree angles. It turns through 13/360  of a circle and It is the same size as 13 one degree angles.

Answer:

214°

Step-by-step explanation:

The measure of an arc that sees the center angle of the circle is equal to the very same angle that it sees

Since the measure of circle is 360° and arc AB is given as 146° the measure of arc ACB should be 360 - 146 = 214°

The measure of arc ACB from the given circle is 214 degree.

An arc of a circle is a section of the circumference of the circle between two radii. A central angle of a circle is an angle between two radii with the vertex at the centre. The central angle of an arc is the central angle subtended by the arc. The measure of an arc is the measure of its central angle.

Given that, ∠AOB=146° (Minor sector)

So,  ∠AOB=360°-146°=204°

The measure of an arc that sees the center angle of the circle is equal to the very same angle that it sees

Since the measure of circle is 360° and arc AB is given as 146° the measure of arc ACB is 214°.

Therefore, the measure of arc ACB from the given circle is 214 degree.
