The circle's shaded area, which has a sector angle of 50 degrees and an arc length of 5/3 pie, has a surface area of 15.67m2.

A circle is created in the plane by each point that is a specific distance from another point (center).  Every pair of points in a circle's closed, two-dimensional plane are evenly spaced apart from the "center." A circular symmetry line is made by drawing a line through the circle. Additionally, it is rotationally symmetric about the center at every angle.

given

A / θ = πr² / 2π

A / θ = r² / 2

A = r² * θ / 2

So, the indicated value of the subject using direct capitalization is $995,909.09.

To find the indicated value of the subject property using direct capitalization, you need to use the following formula:

NOI / Cap Rate = Indicated Value

The overall capitalization rate is 6.00% and the projected first-year NOI is $247,000.

Therefore, Indicated value can be calculated as:

Indicated Value = $247,000 / 0.06 = $4,116,666.67

Another way to find the indicated value is using the Going-out cap rate, which is 22.0% and fifth-year NOI $218,300.

Indicated Value = $218,300 / 0.22 = $995,909.09

It's important to note that a pro forma is a projection and not a guarantee of future results. Also, the value obtained from using direct capitalization method is an indication, not the actual value, as it's based on certain assumptions and it may not reflect the current market conditions.

Answer:

Sandy's experimental probability was exactly the same as the theoretical probability for all three experiments.

Figure A is replicated in scale in Figure B. A figure that is geometrically identical to the original figure is called a scale copy.

Given are two triangular figures, Figure A and Figure B.

The scale factor from figure A to figure B is requested of us.

As a result, Figure B is the last figure and Figure A is the first figure.

Any figure's scale factor is described as stated in equation (1)

[tex]Scale Factor =\frac{\text { Final Dimension }}{\text { Initial Dimension }} \ldots \ldots . . .(1)$[/tex]

We can see from the preceding figures that while figure A uses 4 squares to represent the length of a pair of one parallel sides, figure B only needs 2 squares to represent the same length.

As a result, we can write that using equation (1).

[tex]Scale factor =\frac{\text { Dimension of figure } \mathrm{B}}{\text { Dimension of figure } \mathrm{A}}=\frac{2}{4}=\frac{1}{2}=0.5$[/tex]

Since the scale factor is smaller than 1, the figure is contracted, and the scale factor from Figure A to Figure B is therefore 0. 5.

Irene's measuring error is 12.5% when she believes she has space for a 45-inch-wide bookcase but only has enough for a 40-inch-wide bookcase.

A data value's approximation error is the difference between an exact value and some approximation to it. This inaccuracy can be stated as either an absolute or relative error. A computing machine accuracy or measurement mistake can generate an approximation error. The difference between the estimated and real values in relation to the actual value is indicated as a percentage. In other words, the relative error multiplied by 100 equals the percent error. The percentage error compares an estimate to the true amount and expresses the difference as a percentage. This statistic enables analysts to determine the magnitude of the inaccuracy in relation to the real value.

Here,

percent error,

=(45-40)/40*100

The volume of the cylinder-shaped candle is 157 in³ which diameter and height are 5 inches and 8 inches.

What is cylinder ?

A cylinder is a three-dimensional geometric shape that has two parallel bases that are circular in shape and a curved lateral surface connecting the bases. The bases are located at the top and bottom of the cylinder. The distance between the bases is the height of the cylinder and the distance across the base is the diameter of the cylinder.

The volume of a cylinder is given by the formula V = [tex]\pi r^{2}h[/tex], where r is the radius and h is the height ,

To find the volume of the cylinder-shaped candle, we first need to find the radius. The diameter is given as 5 inches, so we can divide that by 2 to find the radius,

r = 5 inches / 2 = 2.5 inches

Now we can plug this value of r and the given height of 8 inches into the formula:

V = [tex]\pi r^{2}h[/tex] = π(2.5 inches)^2(8 inches) = 3.14 * 6.25 * 8 = 157 in³.

Hence , The volume of the cylinder-shaped candle is 157 in³ which diameter and height are 5 inches and 8 inches.

As per the given mass the potential energy of the ball will be equal to 450 J when it reaches the top to its ascent.

Here we have given that Mass of ball is 1.0kg

And we need to find the value of the kinetic energy  and here we also know that the velocity of the ball is 30m/s

As we all know that Kinetic energy is the energy possessed by a moving object. It is measured in joules, and then it depends on the mass (m) of the object and the velocity (v) by which it moves, then it can be written as,

=> K.E = 1/2mv²

=> KE = 1/2 x 1.0kg x (30m/s)²

when we simplify this then we get

=> KE = 0.5 x 1.0 x 900

Then the value of KE is  450J

Therefore the potential energy of the ball is 450 joules.

The score on his next test must be at least 97 to get an average score of at least 85.

Average value of a set of numbers is a single number which represents the whole numbers in the set.

Average value of a set of numbers is calculated by dividing the sum of all the numbers by the number of values in the set.

Here is is given that,

Jerrod had scores of 75, 82, 94 and 77 on his first four history tests.

We need to find the score of his next test such that the average of all is at least 85.

Let x be the score of his next test.

(75 + 82 + 94 + 77 + x) / 5 ≥ 85

75 + 82 + 94 + 77 + x ≥ 85 × 5

The common ratio of the given geometric sequence is 0.5

We know that for any geometric sequence,

aₙ = arⁿ⁻¹

where aₙ is the nth term of the sequence

a is the first term of the sequence

r is the common ratio.

Hence when we say that the third term is 100 we can conclude that for the series

ar³⁻¹ = 100

or, ar² = 100                                                                                      [1]

Also, we have been given that the eight-term is 3.125

Answer:  Arc EG/GE = 135°

Step-by-step explanation:

Given:

∠EGF = 80°

Arc FG = 65°

Since ∠EGF = 80°, the value of Arc EF = 2(∠EGF)

Therefore, Arc EF = 2(80°) = 160°

The arc measure of an entire circle is 360°.

Therefore,

360° = EF + FG + GE

360° = 160° + 65° + GE

GE/EG = 135°

The measure of the angle m<ROS = 14°.

What is the angle?

An angle is a geometric figure that is defined by two rays that have the same endpoint. The rays are called the sides of the angle and the common endpoint is called the vertex of the angle. The angle is the amount of rotation between the two rays, measured in degrees or radians.

In the given figure,

m<QOS = 46, m<POR = 58 and m<POQ = 26

m<POR = m<POQ + m<QOR

58 = 26 + m<QOR

m<QOR = 32

m<QOS = m<QOR + m<ROS

46 = 32 + m<ROS

m<ROS = 14

Additive inverse is a mathematical term that refers to when two numbers are combined and their sum is equal to zero. To calculate the additive inverse of a fraction, you need to change the sign of the numerator and denominator. In the case of 19 /- 6, the -6 is already negative, so you just need to change the sign of the numerator from 19 to -19. Similarly, for 2 3, you need to change the sign of the numerator from 2 to -2.
