hurry i'm doing a test so
what is the value of x in the equation 5.5x = 17.6?

The answer is B, I just answered this question on my quiz.

Step-by-step explanation:

The given equation or expression is used to determine the total cost of buying carnival tickets.

the total cost is y

Also from the expression the cost of a ticket is $2.5

and x represents the number of tickets

now say x=5, that is 5 tickets, then the cost of buying the 5 tickets is given as

y=2.5(5)

y=12.5

Hence the cost of 5 tickets is $12.5

Answer:

the answer is the answer the answer is x=55 degrees because the angle sum for a triangle is 180 degrees and because we are told angle A and angle C are congruent that means you can simply take 180 - 70 to get 110 and i simply divided that by 2 and got 55 degrees

Step-by-step explanation:

Answer:

A: The area of it would be the equation (10x8)x(26)= 2,080 Inches

The perimeter would be (10+32+10+20)= 72

B: Perimeter on the top part of the frame

C: The area of it would be the equation (10x8)x(26)= 2,080 Inches

D: (10+32+10+20)= 72

Answer:

the answer is 0.4 The reason is because 0.4 x8=0.32

Step-by-step explanation:

Let the number be x .

Reciprocal of x :-

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

An equation to find x :-

[tex]2 \times \frac{1}{x} = 16 \times \frac{1}{20} [/tex]

[tex] \frac{2}{x} = \frac{16}{20} [/tex]

[tex]16 \times x = 20 \times 2[/tex]

[tex]16x = 40[/tex]

[tex]x = \frac{16}{40} [/tex]

[tex]x = \frac{4}{10} [/tex]

[tex]x= \frac{4 \div 2}{10 \div 2} [/tex]

[tex]x = \frac{2}{5} [/tex]

Reciprocal of x :-

[tex] = \frac{5}{2} [/tex]

Which means the number :-

[tex] = \frac{5}{2} [/tex]

We can check it by :-

[tex]2 \times \frac{2}{5} = \frac{16}{20} [/tex]

[tex] \frac{4}{5} = \frac{16}{20} [/tex]

[tex] \frac{4}{5} = \frac{16 \div 4}{20 \div 4} [/tex]

[tex] \frac{4}{5} = \frac{4}{5} [/tex]

LHS = RHS

Which means we have found the correct number .

Therefore , the value of the number , whose reciprocal multiplied by 2 gives 16 times the reciprocal of 20 is :-

Explicación paso a paso:

Como no dijimos qué calcular, también podemos encontrar el tiempo que tarda el automóvil en viajar por la carretera.

Velocidad = Distancia / Tiempo

Tiempo = Distancia / Velocidad

Dado

Distancia = 200 km

Velocidad = 120 km / h

Sustituir

Tiempo = 200/120

Tiempo = 20/12

Tiempo = 1,67 horas

Por tanto, el tiempo que tarda el coche en recorrer la carretera es de 1,67 horas.

Se tarda aproximadamente 1.67 horas en viajar por la autopista de Arabia Saudita.

La velocidad es la relación entre la distancia total recorrida y el tiempo total empleado. Está dado por:

Deje que el tiempo necesario para viajar Arabia Saudita sea t. Por eso:

t = 200/120

Se tarda aproximadamente 1.67 horas en viajar por la autopista de Arabia Saudita.

Answer:

[tex]A = (32.7,47.7)[/tex]

Step-by-step explanation:

Given

[tex]M = (25.5,60.1)[/tex]

[tex]C = (18.3,72.5)[/tex]

Required

Determine the coordinates of A

Midpoint is calculated as thus:

[tex]M(x,y) = (\frac{A_x + C_x}{2}, \frac{A_y + C_y}{2})[/tex]

Substitute the given values

[tex](25.5,60.1) = (\frac{A_x + 18.3}{2}, \frac{A_y + 72.5}{2})[/tex]

Multiply through by 2

[tex]2 * (25.5,60.1) = (\frac{A_x + 18.3}{2}, \frac{A_y + 72.5}{2}) * 2[/tex]

[tex]2 * (25.5,60.1) = (A_x + 18.3, A_y + 72.5)[/tex]

[tex](51,120.2) = (A_x + 18.3, A_y + 72.5)[/tex]

By comparison:

[tex]A_x + 18.3 = 51[/tex]

[tex]A_y + 72.5 = 120.2[/tex]

[tex]A_x + 18.3 = 51[/tex]

[tex]A_x = 51 - 18.3[/tex]

[tex]A_x = 32.7[/tex]

[tex]A_y + 72.5 = 120.2[/tex]

[tex]A_y = 120.2 - 72.5[/tex]

[tex]A_y = 47.7[/tex]

Hence:

[tex]A = (32.7,47.7)[/tex]

Answer:

a. increasing n decreases E

Step-by-step explanation:

The sample size refers to the number (n) of units or observations taken from a population for a study. The results obtained from this sample size can be used to make generalizations about the entire population. The margin of error (E) is a measure of the sampling error or the percentage of the difference between the results obtained from the study and the true population value. The relationship between the sample size (n), and the Margin of error (E) is an inverse. That means

Sample size (n) ∝ 1/E

So, as the sample size increases, the margin of error decreases. This would be even more true if the accurate procedures for the experiment are followed.

Answer:

Step-by-step explanation:

7) ∠1  + 30 = 180                {linear pair}

            ∠1 = 180 - 30

            ∠1 = 150

8)  ∠2 = 30    {Vertically opposite angles are congruent}

9) In ΔLMN,

∠L + ∠N + ∠M = 180   {angle sum property of triangle}

50 + 30 + ∠M = 180

       80 + ∠M = 180

                ∠M = 180 - 80

                ∠M = 100°

10) Sum of exterior angle of a triangle equals to sum of opposite interior angles.

∠B + ∠A = ∠BCD

30 +   ∠A = 80

        ∠A  = 80 - 30

      ∠A = 50

Answer:

28

Step-by-step explanation:

28/1 = 28

Answer:

Step-by-step explanation:

1)

A. 2 meters to centimeters

1 m = 100 cm

[tex]2 m = 2 \times 100 \\2 m = 200 cm = 2 \times 10^2[/tex]

B)108 centimeters to meters

100 cm =1 m

[tex]1 cm = \frac{1}{100} m \\108 cm = \frac{108}{100}=108 \times 10^{-2} m[/tex]

C)2.49 meters to centimeters

1 m = 100 cm

[tex]2.49 m = 2.49 \times 100 = \frac{249}{100} \times 100 = 249 cm[/tex]

D)50 centimeters to meters

100 cm = 1m

[tex]1 cm = \frac{1}{100} m \\50 cm = \frac{50}{100}= 5 \times 10^{-1} m[/tex]

E)6.3 meters to centimeters

1 m = 100 cm

[tex]6.3 m = 6.3 \times 100=\frac{63}{10} \times 100 = 630 cm[/tex]

F)7 centimeters to meters

100 cm = 1 m

[tex]1 cm = \frac{1}{100} m\\\\7 cm = \frac{7}{100} = 7 \times 10^{-2} m[/tex]

2)

a)4 meters to millimeters

1 m = 1000 mm

[tex]4 m = 4000 = 4 \times 10^3 mm[/tex]

b)1.7 meters to millimeters

1 m = 1000 mm

[tex]1.7 m = 1.7 \times 1000= \frac{17}{10} \times 1000=17 \times 10^2 mm[/tex]

7x + 28

Step-by-step explanation:

Line up the columns just like with standard addition.  Keep the x numbers in the same columns and keep the integers in their columns.  It will look like this:

                7x     +     28

Answer:

AUB=2,4,6,8,10 & AnB=1,3,5,7,9

Answer:

Step-by-step explanation:

Given the expression 2y+13=y+5

To get the value of y, we willow the following steps:

Subtract 2y to both sides:

2y+13-2y = y+5-2y

13 = -y+5

subtract 5 from both sides:

13-5 = -y+5-5

8 =  -y

-y = 8

multiply both sides by -1

-(-y) = -8

y = -8

Hence the value of y = -8 not -14

So NO,if you continue to solve, y would not be -14
