Answer:

x = -9 ; x = 7

Step-by-step explanation:

We have to find two numbers whose product is -63 and whose sum is 2

the two numbers are 9 and -7

(x+9)(x-7) = 0

x = -9

x = 7

Answer:

the answer is 2x-14.

Step-by-step explanation:

because 2 multiply both the number 2 and x

Answer: 11.20

Step-by-step explanation:

Divide. 56.00 ÷ 5 = 11.20 therefore each shirt cost 11.20 Hope that helps!

Answer:

Divide.

Answer : option B

Step-by-step explanation:

Cost             Number of shirts

 56                      5

  x                        1

 [tex]\frac{56}{x} = \frac{5}{1}[/tex]

[tex]5 \times x = 56 \times 1\\\\x = \frac{56}{5} = 11.20[/tex]

Answer:

the value of x = 3 and y = 3

Step-by-step explanation:

2x + y = 9 ------------ (1)

-2y -2x = -22 ------------ (2)

Subtract (1) from (2)

-2x -2y = -22

2x + y = 19

----------------------

       -y = -3

        y = 3

Put the value of y in equation 1

2x + y = 9

2x + 3 = 9

2x = 9 - 3

2x = 6

x = 6/2

x = 3

Therefore, the value of x = 3 and y = 3

Answer:

On average, customer spends approximately  98 min at Little’s Law Firm

Step-by-step explanation:

Given the data in the question;

Arrival rate λ = 6 per 8 hours =  6 / ( 8 × 60 )min = 6 / 480 = 0.0125 per minute

Service rate δ = 1 / 50 min = 0.02 per minute

Standard deviation σ = 20 min

Now,

Utilization rate U = Arrival rate / Service rate

U = 0.0125 / 0.02

Utilization rate = 0.625

Number of people in Queue will be;

⇒ ( (λ² × σ²) + U² ) / ( 2 × ( 1 - U )

we substitute

⇒ ( (0.0125² × 20²) + 0.625² ) / ( 2 × ( 1 - 0.625 )

⇒ ( 0.0625 + 0.390625 ) / ( 2 × 0.375 )

⇒ 0.453125 / 0.75

Number of people in Queue = 0.6042

Now

Wait in the Queue = Number of people in Queue / λ

= 0.6042 / 0.0125 = 48.336

Wait Time in Office = Wait in the Queue + ( 1 / δ )

= 48.336 + ( 1 / 0.02 )

= 48.336 + 50

Wait Time in Office = 98.336 ≈ 98 min

Therefore, On average, customer spends approximately  98 min at Little’s Law Firm

Hi there, I like your pfp!

The correct answer should be 11 1/2!

Step-by-step explanation:

-48/-8 = 6 4/8 = 6 1/2

6 1/2 + 5 =

11 1/2

Anyways, hope this helped!

Answer:

if iam not mistaking the answer would be 25

Answer:

82° because

98° + 70° = 168°

360° - 168° = 192°

192° is for two angles, so it can't be 192°, 220°

it's not VERY obtuse angle. So it remains only 82°

Geometry

This makes a cube because a cube has 6 faces, 8 vertices, and 12 edges.

Answer: 8

Step-by-step explanation

Answer:

$8

Step-by-step explanation:

If we just keep track of the money in the account, we can solve this pretty quickly. If the balance is -20, and we subtract another 10 from it, it gives us -30. $38 is then deposited into the account, giving us a balance of $8.

[tex]-20-10+38=8[/tex]

Given :

The volume of a cone is 202.92 cubic units. The cylinder has the same height and radius as the cone.

To Find :

The length of height and radius .

Solution :

Volume of cone is given by :

[tex]V = \dfrac{\pi r^2 h}{3}\\\\V = \dfrac{\pi r^3}{3}\\\\r = \sqrt[3]{\dfrac{3V}{\pi}} \\\\r = \sqrt[3]{\dfrac{3 \times 202.92}{\pi}}\\\\r = 5.79 \ units[/tex]

Hence, this is the required solution.

Answer:5

Step-by-step explanation:

Answer:

Marina recibe 30 euros, Alejandra recibe 40 euros y Jorge recibe 50 euros.

Step-by-step explanation:

Dado que la abuela de Jorge, cuando llegan las fechas navideñas, reparte 120€ entre los tres nietos de la siguiente forma: Jorge, como es el mayor, recibe 10 € más que su prima Alejandra, y esta 10 € más que la prima pequeña Marina, para determinar cuánto dinero recibe cada uno se debe realizar el siguiente cálculo:

J = A + 10

A = M + 10

M = M

J + A + M = 120

A + 10 + M + 10 + M = 120

M + 10 + 10 + M + 10 + M = 120

3M + 30 = 120

3M = 120 - 30

M = 90 / 3

M = 30

Por lo tanto, Marina recibe 30 euros, Alejandra recibe 40 euros y Jorge recibe 50 euros.

Answer:

The coefficient of variation after the tax is imposed is 0.033

Step-by-step explanation:

Given

[tex]\mu =1000[/tex] --- mean

[tex]\sigma^2 = 1200[/tex] --- variance

[tex]tax = 10\%[/tex]

Required

The coefficient of variation

The coefficient of variation is calculated using:

[tex]CV = \frac{\sqrt{\sigma^2}}{\mu}[/tex]

After the tax, the new mean is:

[tex]\mu_{new} = \mu * (1 + tax)[/tex]

[tex]\mu_{new} = 1000 * (1 + 10\%)[/tex]

[tex]\mu_{new} = 1100[/tex]

And the new variance is:

[tex]\sigma^2_{new} = \sigma^2 * (1 + tax)[/tex]

[tex]\sigma^2_{new} = 1200 * (1 + 10\%)[/tex]

[tex]\sigma^2_{new} = 1320[/tex]

So, we have:

[tex]CV = \frac{\sqrt{\sigma^2}}{\mu}[/tex]

[tex]CV = \frac{\sqrt{1320}}{1100}[/tex]

[tex]CV = \frac{36.33}{1100}[/tex]

[tex]CV = 0.033[/tex]

Answer:

First the mode.  Since 5 popped up the most, 5 is the mode.

Next is the median.  I crossed 1 dot from each side until it shows the last dot, and 5 was the last one.

After that the range.  9-2=7

Finally the worst, the mean... 2+2+3+3+3+4+5+5+5+5+5+6+6+6+8+9+9+9+9

=104/19=5.47

SO, Mode=5 Median=5 Range=7, and the mean is 5.47 (rounded nearest hundred)

Answer:

12 km

Step-by-step explanation:

--------------------------------

time out + time back = total time

d/5 + d/4 = 5.4

multiply both sides by 20 to clear the fractions

4d + 5d = 108

9d = 108

Divide both sides by 9

d = 12 km

Answer:Generally, the algebraic expression should be any one of the forms such as addition, subtraction, multiplication and division. To find the value of x, bring the variable to the left side and bring all the remaining values to the right side. Simplify the values to find the result.

Answer:

what I think it is it's -4

Answer:

n = 3

Step-by-step explanation:

6(8 - 2n) = 2n + 6

48 - 12n = 2n + 6

-12n - 2n = 6 - 48

-14n = -42

n = -42/-14

n = 3

Step-by-step explanation:

Answer:

r = -6

Step-by-step explanation:

Equation of a line:

The equation of a line has the following format:

[tex]y = mx + b[/tex]

In which m is the slope and b is the y-intercept.

Slope 3/4

This means that [tex]m = \frac{3}{4}[/tex], and thus:

[tex]y = \frac{3}{4}x + b[/tex]

(6,3)

This means that when [tex]x = 6, y = 3[/tex]. We use this to find b. So

[tex]y = \frac{3}{4}x + b[/tex]

[tex]3 = \frac{3}{4}(6) + b[/tex]

[tex]b = 3 - \frac{18}{4} = \frac{12}{4} - \frac{18}{4} = -\frac{6}{4}[/tex]

So

[tex]y = \frac{3}{4}x - \frac{6}{4} = \frac{3x - 6}{4}[/tex]

(-6, r)

r is y when [tex]x = -6[/tex]. So

[tex]y = \frac{3(-6) - 6}{4} = -6[/tex]

So r = -6.

Answer:

y =−12 /1 x−3 /5
