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]

Hence total payment for expenses is $46281

Payments refers to outstanding amount to be paid for the liable items. We can also say that banknotes and coins (cash), as well as deposits and credit on an account with a financial institution or a similar entity that can be run using payment instruments, are all examples of means of payment.

annual real estate tax = $1,231

annual insurance         = $1,087

David' monthly house payments=$46821

To calculate total payments we will now add all the payments.

Answer:

V 8 on 8 D

Step-by-step explanation

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.

Step-by-step explanation:

They are Alternate angles so they need to be equal to each other meaning you can right them like this;

[tex]4x + 2 = 86[/tex]

So to work out x you just have to separate x;

[tex]4x = 86 - 2 \\ 4x = 84 \\ x = \frac{84}{4} [/tex]

So

[tex]x = 21[/tex]

Answer:

its not the top right one

Step-by-step explanation:

the other three are right

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:

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 %

B. Kayleigh because she reads at a rate of 6 pages per minute.

Step-by-step explanation:

To find the amount of pages both people read in a minute, we can simply divide:

Jake- 45/9 = 5 pages a minute

Kayleigh- 60/10 = 6 pages a minute

Therefore, Kayleigh reads more pages a minute because 6 > 5.
