Answer:

40 π ft or 125.6ft

Step-by-step explanation:

If the sprinkler can spray water 20 ft, that means the radius is 20 ft and to get the circumference we do 2 r π

or 2r*3.14

The answer is either 40 π ft

or 125.6ft

Answer:

Step-by-step explanation:

6*(17*50) = 6 * (50 * 17)     {Commutative property}

               = (6 * 50) * 17    {Associative property}

               = 300 * 17

               = 5100

Answer:

-36

Step-by-step explanation:

12 * 3 = 36

When you multiply by a negative number, the number becomes a negative therefore, -12*3 = -36

Answer:

-36

Step-by-step explanation:

When multiplying a negative and a positive the answer is always going to be negative.  So 12x3=36 and the 12 is negative and the 3 is positive, so the answer is -36.

Answer:

the hourly pay fro the internship is $7/hr

Step-by-step explanation:

The statement can be written mathematically as below

[tex]18 = 4 + 2x[/tex]

the hourly rate of the internship is [tex]x[/tex]

solving the equation, we have

[tex]18 = 4 + 2x[/tex]

subtract 4 from both sides of the equation

[tex]18 - 4 = 4 +2x -4[/tex]

[tex]14 = 2x[/tex]

[tex]x = 14/2[/tex]

[tex]x = 7[/tex]

the hourly pay fro the internship is $7/hr

Answer: $7

Step-by-step explanation:

According to the question , we have

$18=4+2 (amount of the student earns per hour at an internship)

Let x be the amount of the student earns per hour at an internship, then the equations will be

18 = 4+2x

Subtract 4 from both sides , we get

14 = 2x

Divide both sides by 2, we get

7 = x

Hence, the hourly pay of the intership was $7 .

12x+6=10x+10

12X-10X=10-6

2X=4

X=4÷2=2

Answer:

x = 2

Step-by-step explanation:

Basic proportionality theorem,

[tex]\frac{AB}{BD}=\frac{CB}{BE}\\[/tex]

AB = AD + DB = 4+6 = 10

CB = CE + EB = x + x +1 = 2x +1

[tex]\frac{10}{6}=\frac{2x+1}{x+1}[/tex]

Cross multiply

10*(x+1) = 6*(2x+ 1)

10*x + 10*x = 6*2x + 6*1

10x + 10 = 12x + 6

Subtract 10x from both sides

10x + 10 - 10x = 12x + 6 - 10x

10 = 2x + 6

Subtract 6 form both sides

10 - 6 = 2x + 6 - 6

4 = 2x

Divide both sides by 2

4/2 = 2x/2

2  = x

x = 2

Answer:

{-5, -4, 0, 1, 2}

Step-by-step explanation:

The domain is the inputs or the x values

{-5, -4, 0, 1, 2}

Answer:

See below.

Step-by-step explanation:

The domain of a relation is all of the x-coordinates.

So we have the relation:

{(-5,4), (-4,2), (0,2), (1,3), (2,4)}

This means that the domain will be the following values:

{(-5,4), (-4,2), (0,2), (1,3), (2,4)}

So, our domain is:

[tex]\{-5, -4, 0, 1, 2\}[/tex]

Note that the domain is in ascending order.

Let x be a variable, and f(x) a function of that variable.

f(2) is a number ; it's the value of the function f(x) when x = 2, assuming that value exists.

f(x) = 2 is a statement ; it says there is some value of x for which the function returns a value of 2. Because it's a statement, it can be true or false.

Here's an example:

Define f(x) = sin(x). Then f(2) = sin(2) ≈ 0.909297.

If x is a real number, then the statement sin(x) = 2 is false, because -1 ≤ sin(x) ≤ 1 for all real x.

If we replace 2 with 1, on the other hand, we get

f(1) = sin(1) ≈ 0.84147

and

sin(x) = 1  ==>  x = π/2 + 2nπ

where n is any integer. (So we're talking about numbers like π/2, -3π/2, 5π/2, -7π/2, and so on.) We're saying here that any real number x of the above form satisfies the equation and makes the statement true.

Divide 8 on both sides

-1=b

• Answer:

b = - 1

b = - 1

Answer:

Step-by-step explanation:

So there are 4 chocolate chips and 12 oatmeal. In total, there are 16 cookies.

The probability of selecting a chocolate chip when you reach in for the first time will be 4/16 or 1/4.

The second time, you reach in, however, there would be one less chocolate chip cookie because you would've pulled one out previously. Thus, the probability is now 3/15 or 1/5.

So, the probability of pulling a chocolate chip cookie consecutively is:

[tex]\frac{1}{4}\cdot\frac{1}{5}=\frac{1}{20}[/tex]

Answer:

Supongo que en realidad dice

"... Para llegar de la planta baja hasta el piso 9..."

Ok, el elevador comienza en el piso 0, y llega hasta el piso 9 después de 5 movimientos.

De estos 5 movimientos, 3 suben (los podemos definir como positivos)

y 2 bajan (los escribimos como negativos).

Entonces, comienzo en 0.

0 + A + B + C - D - E = 9.

ahí dice que:

"desde el piso 0, tengo 3 subidas y dos bajadas de tal forma que el resultado final es el piso 9"

Una expresión algebraica matemática consta de variables y constantes junto con operaciones algebraicas. Al resolver problemas de palabras algebraicas, es necesario que los problemas se traduzcan con precisión en ecuaciones y se resuelvan correctamente.

Dado que:

Para configurar una operación que indique el número de pisos que recorrió el ascensor con cada movimiento;

Vamos a considerar

∴

Así, la puesta a punto de la operación que indica el número de pisos que recorrió el ascensor con cada movimiento se puede deducir de la diferencia entre el movimiento de subida y bajada será igual a 9.

Por lo tanto, podemos concluir que la configuración de la operación es:

3a - 2b = 9

Answer:

Domain: [tex]\{x|x\in\mathbb{R}\}[/tex]

Range: [tex]\{y|y\in\mathbb{R},y\leq -2\}[/tex]

Step-by-step explanation:

The domain is the span of x-values the graph covers.

The range is the span of y-values the graph covers.

The given graph is a quadratic. We can see that the x-values will extend infinitely in both directions.

Thus, the domain is all real numbers.

In set notation, this is:

[tex]\{x|x\in\mathbb{R}\}[/tex]

From the graph, we can see that the maximum value is y=-2. The graph won't ever go above this.

So, the range is all real numbers less than or equal to -2.

In interval notation, this is:

[tex]\{y|y\in\mathbb{R},y\leq -2\}[/tex]
