Using Hamilton method for apportioning, the total artists will be 200.

Using Hamilton method for apportioning :

total artists = 94+51+55 = 200

booths = 39

booths for group = (artists in group) / (total artists / no. of booths)

= (artists in group) / (200/39)

booths for painters = (94) / (200/39) = 18.33

= 18 {rounded to nearest integer}

booths for sculptors = (51) / (200/39) = 9.945

= 10 {rounded to nearest integer}

booths for weavers = (55) / (200/39) = 10.725

Answer:

Possibly A

Step-by-step explanation:

Answer:

76.93

Step-by-step explanation:

The measure of the angle ∠P is given by the law of sines and ∠P = 46°

Given data ,

Let the triangle be represented as ΔMNP

Now , the measure of side MP = 46

The measure of side MN = 34

And , the measure of ∠MNP = 78°

Now , from the law of sines , we get

So , a / sin A = b / sin B = c / sin C

On simplifying , we get

34 / sin P = 46 / sin 78°

Multiply by sin P on both sides , we get

sin P ( 46 / 0.97814760073 ) = 34

sin P = 0.72297866

Taking inverse on both sides , we get

sin⁻¹ ( 0.72297866 ) = 46.30°

Hence , the measure of angle is P = 46°

The solution of the triangle is shown below;

Angle A - 26.98°

Angle C - 118.6°

Side c -  47.98

If you know the length of one side and the measure of the opposite angle, or the length of two sides and the measure of the angle between them, you can use the Law of Sines to find the other parts of the triangle.

Using the sine rule;

a/Sin A = b/Sin B

aSin B = bsinA

Sin A = bSinB/a

A = Sin-1( bSinB/a)

A = Sin-1(30.9 * Sin 34.42/38.5)

A = 26.98°

Then;

C = (180 - 26.98 + 34.42)

C = 118.6°

Using the sine rule again;

b/sinB = c/Sin C

c = bSin C/Sin B

c = 30.9 * Sin 118.6/Sin 34.42

c = 27.12/0.565

c = 47.98

It would be 603.2 square inches.

If a triangle has a right angle (90 degrees), it is called a right triangle. The side opposite the right angle is called the hypotenuse, and it is the longest side of the triangle. The other two sides are called the legs.

To find the length of the third side of a right triangle, we can use the Pythagorean theorem, which states that in a right triangle, the sum of the squares of the two legs is equal to the square of the hypotenuse.

The Pythagorean theorem can be written as:

a^2 + b^2 = c^2

where a and b are the lengths of the two legs, and c is the length of the hypotenuse.

But you already know c, and with that c^2, you want to find a through a^2(you can also look for b, it would be the same)

If you rearrange the equasion you get a^2=c^2-b^

Once we have these lengths

c=15,so c^2 is 15^2=15*15=225

b=10,so b^2 is 10^2=10*10=100

we can plug them into the Pythagorean theorem and solve for the unknown side.

a^2=c^2-b^2

a^2=225-100=1125

Rigid transformation refers to a type of geometric transformation that preserves the shape and size of an object. In other words, the transformed object is congruent to the original object.

Rigid transformations can be of two types -

Translation refers to moving an object in a straight line, while rotation refers to turning an object around a fixed point.

Rotation, in particular, has the effect of changing the orientation of the object. However, the length of each side and the angles between them will remain the same.

In a rigid transformation, the position of every point in the object is changed, but the distances between points remain unchanged, as well as the angles between lines and the area of the object.

The measure of angle x is 114.6°

Here, the central angle of sector of circle is represented by x.

We know that the formula for the area of sector.

A = θ/360 × πr²

where  θ is the central angle

and r is the radius of the circle

Here, the area of the sector is equal to the area of the square.

Using the formula for the area of square,

A = side²

A = r²

Since area of sector = area of square,

x/360 × πr² = r²

x = 360/π

In other words, it is a process that takes one or more inputs and produces a corresponding output. Functions are commonly represented using equations, graphs, or tables. They are used in various branches of mathematics, science, engineering, and technology to model real-world phenomena, make predictions, and solve problems.

The volume of a sphere whose diameter is 18 centimeters is 972π cubic centimeters. If its diameter were reduced by half, its volume would be 1/8 of its original volume. So, correct options are D for both blanks.

The diameter of a sphere is 18 cm, so its radius is half of the diameter, which is 9 cm. The formula for the volume of a sphere is (4/3)πr³, where r is the radius of the sphere.

Using this formula, we can calculate the volume of the sphere as follows:

V = (4/3)π(9³)

V = (4/3)π(729)

V = 972π cubic cm

Therefore, the volume of the sphere is 972π cubic cm.

Now, if the diameter of the sphere is reduced by half, the new diameter would be 9 cm, which means the new radius would be half of 9 cm, which is 4.5 cm. Using the same formula for the volume of a sphere, we can calculate the new volume of the sphere as follows:

V' = (4/3)π(4.5³)

V' = (4/3)π(91.125)

V' = 121.5π cubic cm

To find the ratio of the new volume to the original volume, we can divide the new volume by the original volume:

V'/V = (121.5π) / (972π) = 1/8

Therefore, the answer to the first part of the question is option (d) 972π cubic cm, and the answer to the second part of the question is option (d) 1/8.

The maturity value at the end of 6 years is $37,098 (option a).

To calculate the maturity value of Ariana's loan, we can use the formula for compound interest. The formula for compound interest is:

A = P(1 + r/n)ⁿˣ

Where:

A = the maturity value

P = the principal amount borrowed

r = the annual interest rate (as a decimal)

n = the number of times interest is compounded per year

x = the length of time the loan is taken out for

In this case, Ariana borrowed $31,500 for 6 years at an interest rate of 2.9%. We know that interest is compounded annually, so n = 1. Substituting these values into the formula, we get:

A = 31,500(1 + 0.029/1)¹ˣ⁶

A = 31,500(1.029)⁶

A = 31,500(1.1945)
