Answer:

Step-by-step explanation:

[tex]\frac{-33}{9}+2=\frac{-33}{9}+\frac{2*9}{1*9}\\\\\\=\frac{-33}{9}+\frac{18}{9}\\\\= \frac{-33+18}{9}\\\\=\frac{-15}{9}[/tex]

GCF of 15 and  9 is 3. so divide both numerator and denominator by 3

Answer:

4,200

Step-by-step explanation:

Tenemos un total de:

4 libros de matemáticas

3 libros de biología

3 libros de religión

10 libros en total.

Ahora vamos a contar la cantidad de opciones que tenemos para cada posicion.

Primer libro (tenemos 10 opciones)

segundo libro (tenemos 9 opciones, porque ya colocamos un libro)

tercer libro (tenemos 8 opciones, porque ya colocamos dos libros)

Con esto ya podemos estimar el número de opciones para cada posicion, y sabemos que el número total de combinaciones es igual al producto entre los números de opciones para cada caso. El número total de combinaciones es:

C = 10*9*8*7*6*5*4*3*2*1 = 10!

Ahora si asumimos que no podemos diferenciar los libros de matemáticas, entonces no debemos contar sus permutaciones (si tenemos 4 libros de matemáticas, tenemos 4*3*2*1 permutaciones = 4! permutaciones). Debemos dividir al numero total de combinaciones por 4!.

Y lo mismo pasa para las 3! permutaciones de los libros de biología y las 3! permutaciones de los libros de religión.

Entonces el número total de combinaciones diferentes es:

[tex]C = \frac{10!}{3!*4!*3!} = \frac{10*9*8*7*6*5*4*3*2*1}{(3*2*1)*(4*3*2*1)*(3*2*1)} = 4,200[/tex]

Step 2. Identify what you are looking for.

We are looking for the number of student and adult tickets.

Step 3. Name. Represent the number of each type of ticket using variables.

We know the number of adult tickets sold was  

5

 less than three times the number of student tickets sold.

Let  

s

 be the number of student tickets.

Then  

3

s

−

5

 is the number of adult tickets.

Multiply the number times the value to get the total value of each type of ticket.

 each and  

136

 adult tickets at

Answer:

She made eight 2 pointers

She made four  3 pointers

Step-by-step explanation:

2x + 3y = 28

x + y    = 12                 Multiply this equation by 2

2x + 2y =24

Write the first and third equations underneath each other,

2x + 3y = 28

2x + 2y = 24              Subtract.

        y = 4

x + y = 12

x + 4 = 12                     Subtract  4 from each side

Step-by-step explanation:

Answer:

178.98 ft2

Step-by-step explanation:

The approximate area of the path is 179 ft².

The area of the smaller circle is calculated as follows;

A₁ = πr₁²

Where;

A₁ = π x 8²

A₁ = 201.088 ft²

A = πr₂²

Where;

A₂ = π x (11)²

A₂ = 380.18 ft²

A = A₂  - A₁

A = 380.182 ft²  -  201.088 ft²

A = 179.094 ft²

Thus, the approximate area of the path is 179 ft².

AB= 16❤

Step-by-step explanation:

OB= 10

EB²+6²= 10²

EB²= 64

EB=8

2×8=16

The length of line AB in the intersecting chords is determined as 16 units.

The length of line AB is calculated by applying intersecting chord theorem as follows;

The radius of the circle = 10

Applying Pythagorean theorem as follows;

EB² + 6²= r²

where;

EB² + 6²= 10²

EB² = 10² - 6²

EB² = 100 - 36

EB²= 64

EB = √ 64

EB = 8

Since EB is the half of length AB, then the value of the length AB is calculated as;

AB = 2 x 8

AB = 16 units

K is Center, Radius KJ KI,KI, JR diameter.

Here we have given a diagram from the given diagram

Center :- The center of a circle is the point equidistant from the points on the edge

Therefore center is k.

Radius:-The distance from the center of the circle to any point on it's circumference

Radius is KJ,KL,KI

Chord :-The chord of a circle can be defined as the line segment joining any two points on the circumference of the circle.

chord is J and I
