Half of the sum of 3x and 4

Answer:

The measure of angle D is of 66º.

Step-by-step explanation:

Vertical Angles:

If two angles are vertical, they have the same measure.

In this question:

Angles C and D are vertical.

Angle C measures 66º.

So the measure of angle D is of 66º.

Answer:

-4x-1

Step-by-step explanation:

combine 4x and -8x to make -4x and combine -2 and 1 to make -1

Answer:

2 = 4/2

Step-by-step explanation:

Well the one for the 2 wholes, Since 2 wholes equal 4/2

because 4/2 simplified is 2 whole it I believe would be 4/2

Answer:4/2,5/2

Step-by-step explanation:

I believe that 4,2 because it's going in order and 4/2= 2 which is shown below. And 5,2 because 5/2=2.5 which is half of 2 and 3.

Answer:

2.5 bottles

Step-by-step explanation:

10 * 500 ml = 5000 ml

5000 ml = 5 l

5/2 = 2.5

2-liter bottles of soda will need 2.5 bottles to fill ten 500 milliliter containers.

A liter is a cubic meter unit of volume which is equal to 1000 cubic centimeters.

1 liter = 1000 milliliters

Ten 500 milliliter containers

10 × 500 ml = 5000 ml

5000 ml = 5 l

2-liter bottles of soda will you need

5/2 = 2.5bottles

Therefore, 2-liter bottles of soda will need 2.5 bottles to fill ten 500 milliliter containers.

Answer:

Solve the equation for x.

The simplified system is the arbitrary solution of the original system of equations.

Y=x+14

y=18−x2

Reorder 18

and −x2.

y=−x2+18

Y=x+14

Solve the equation for Y.

Y=−2y+50

x=36−2y

Reorder 36

and −2y.

x=−2y+36

Y=−2y+50

Step-by-step explanation:

Step-by-step explanation:

given

[tex]y = x + 14 \\ y - x = 14 \\ - x + y = 14[/tex]

as equation 1

and

[tex]x + 2y = 36[/tex]

as equation 2.

We will now use elimination method to solve simultaneous equations.

We will use equation 1 + equation 2 to eliminate x and solve for y.

[tex] - x + x + y + 2y = 14 + 36 \\ 0 + 3y = 50 \\ 3y = 50 \\ y = 50 \div 3 \\ = \frac{50}{3} \: or \: 16 \frac{2}{3} [/tex]

Now substitute y into equation 1.

[tex]y = x + 14 \\ x + 14 = y \\ x = y - 14 \\ x = 16\frac{2}{3} - 14 \\ = 2 \frac{2}{3} [/tex]

Answer:

Options 2, 3, 4, 5 are the solutions.

Step-by-step explanation:

Option 1).

x + 10 = -5

x = -10 - 5

x = -15

Therefore, x = -5 is not the solution.

Option 2).

-x² + 50 = 25

-x² = 25 - 50

-x² = -25

x² = 25

x = ±5

Therefore, x = -5 is a solution

Option (3)

|2x| = 10

2x = ± 10

x = ± 5

Therefore, x = -5 is a solution.

Option (4)

x < 0

Since, -5 < 0

Therefore, x = -5 is a solution.

Option (5)

2x < 10

x < 5

Since, -5 < 5

Therefore, x = -5 is a solution.

Options 2, 3, 4, 5 are the solutions.

T₁₀ = 1/16

S₁₀ = 63,9375

Explicación paso a paso:

Dado el término de un médico de cabecera como 32, 16, 8, 4 ...

El enésimo término de un médico de cabecera se expresa como;

Tn = arⁿ⁻¹

a es el primer término

r es la razón común

n es el número de términos

Dado

a = 32

r = 16/32 = 8/16 = 4/8 = 1/2

n = 10 (ya que necesitamos el décimo término de la secuencia)

Sustituir en la fórmula;

Tn = arⁿ⁻¹

T₁₀ = 32 (1/2) ¹⁰⁻¹

T₁₀ = 32 (1/2) ⁹

T₁₀ = 32 (1/512)

T₁₀ = 32/512

T₁₀ = 1/16

Por lo tanto, el décimo término de la secuencia es 1/16.

La suma de un GP se expresa como se muestra;

Sₙ = a (1-rⁿ) / 1-r para r <1

S₁₀ = 32 (1- (1/2) ¹⁰) / 1-1 / 2

S₁₀ = 32 (1-1 / 1024) / 1/2

S₁₀ = 64 (1 - 1/1024)

S₁₀ = 64 (1023/1024)

S₁₀ = 63,9375

por lo tanto, la suma de los primeros diez términos es 63,9375

Answer:

Answer B

Step-by-step explanation:

You have to use the pythagorean theorm which states that a^2+b^2=c^2

So, 7^2+x^2=9^2

49+x^2=81 subtract 49 from both sides of the equation

x^2=32

x=sqrt(32)

sqrt(32)=sqrt(16)*sqrt(2)

=4*sqrt(2)      

To solve this problem, we should note that there are:

total questions = 100

questions answered correctly = 90

questions that needed additional clues = 10

1. The first question is to find the probability that in the third question, Mary would need additional clue. Therefore this implies that in the first and second questions, Mary would answer it correctly. Therefore:

Probability = (question 1 answered correctly) * (question 2 answered correctly) * (question 3 needed clue)

Probability = (90/100)*(89/99)*(10/98)

Probability = 0.08256 = 8.26%

2. The second question finds for the probability that two consecutive needs additional clue, therefore:

Probability = (question 1 needed clue) * (question 2 needed clue)

Probability = (10/100)*(9/99)

Probability = 9.1*10^-3 = 0.91%

Answer:

1. The estimated probability that it would take at least three questions for Mary to need additional clues is 0.24

2. The estimated probability that Mary needed additional clues to answer two consecutive questions is 0.06

Answer:

1 1/2

Step-by-step explanation:

3/12 * 6

6 is simply 6/1 so

3/12*6/1

multiply from side to side so

3*6=18

and

12*1=12

18/12

simplify to a mixed number

18 goes in 12 once with a remainder of 6, or 18-12=6 so

1 6/12

6/12 can both be simplified by 6 so you divide both by 6

6/6=1 and 12/6=2

1/2

add it back to the whole number

1 1/2
