B is the midpoint of AC. if AB = x+5 and BC = 2x-11, find the measure of AB

Answers

Answer:

2 is the answer

Step-by-step explanation:

Answer:

AB = 21

Step-by-step explanation:

Since B is the midpoint of AC , then

BC = AB

2x - 11 = x + 5 ( subtract x from both sides )

x - 11 = 5 ( add 11 to both sides )

x = 16

Then

AB = x + 5 = 16 + 5 = 21

Chelsey puts twelve colored pieces of chocolate candy in a bag. Three pieces are green,
four pieces are yellow, two pieces are purple, and three pieces are red. She draws one
piece of candy from the bag at a time and eats it.

order: red, green, yellow? (3 points)
b. What is the probability that Chelsey will draw out three pieces of candy in this
order: green, yellow, red? (3 points)

B) 3/110  

C) 3/110  

D) The order doesn’t matter as long as you are drawing out the same three colors.  The probability doesn’t change.

Step-by-step explanation:  

A) 3/12x3/11x4/10=36/1320= 9/330 = 3/110  

B) 3/12x4/11x3/10=36/1320= 9/330 = 3/110  

C) 4/12x3/11x3/10=36/1320 = 9/330 = 3/110

-100-4√5

Step-by-step explanation:

Given the polynomial expression

p(x) = x³+x²+√5x + √5

p(-5) = (-5)³+(-5)² + √5(-5) + √5

p(-5) = -125 + 25 -5√5 + √5

p(-5) = -100-4√5

Jimy traveled the entire route of the parade, but his suster Jemima only traveled along Elm Street. How much further did Jimmy travel than Jemima?

Answers

Answer:

See Explanation

Step-by-step explanation:

Given

[tex]Jimmy \to[/tex] Entire Route

[tex]Jemima \to[/tex] Elm Street

Required

How much more did Jim travel

The question is incomplete, as the resources to calculate the distance covered by both are not given.

To solve a question like this;

First, calculate the distance by both, then subtract the smaller distance

Take for instance, after calculating the distance, you have:

[tex]Jimmy= 850m[/tex]

[tex]Jemima = 500m[/tex]

The difference d is:

[tex]d = 850m - 500m[/tex]

[tex]d = 350m[/tex]

i.e. Jimmy traveled 350m much more

Angle

= 96° and angle
z

Work out
x

Answers

Answer:

x = 136°

Step-by-step explanation:

We can use a theorem to help us.

Theorem:

The measure of an exterior angle of a triangle is equal to the sum of the measures of the remote interior angles.

For exterior angle x, the remote interior angles are z and <CBD.

From the theorem, we get this equation.

x = z + m<CBD

We know z = 52°.

We need to find m<CBD.

Angles CBD and y are a linear pair. They are supplementary, so the sum of their measures is 180°. We are given y = 96°.

m<CBD + y = 180°

m<CBD + 96° = 180°

m<CBD = 84°

x = z + m<CBD

x = 52° + 84°

x = 136°

Answer:

x = 136°

Step-by-step explanation:

∠ABD = y = 96°, ∠ABD + ∠DBC must be equal to 180° because they form a straight angle.

[tex]y + B = 180\\96 + B = 180\\B = 180 - 96 = 84[/tex]

∠BDC = z = 52° and ∠DBC = B = 84.

Angles ∠BDC, ∠DBC, and ∠BCD must have a sum of 180° because the sum of the interior angles in a triangle is 180°.

[tex]180=(180 - y) + 52 + C\\180=(180 - 96) + 52 + C\\180 - (52 + 84) = C\\C = 44[/tex]

The interior angle at C is 44. Line DCE forms a straight line, therefore having an angle of 180°. To find x, the sum of x and interior angle C is 180°.

[tex]180 = C + x\\180 = 44 + x\\x = 180-44\\x = 136\\[/tex]

Angle ∠BCE = x = 136.

Si la aceleración de gravedad en la superficie de nuestro planeta es de 9,8m/s2, entonces ¿Cuál sería el peso de una persona de 50 kg de masa que se encuentre sobre su superficie?

Answers

Answer:

El peso de una persona de 50 kg de masa que se encuentre sobre la superficie del planeta es 490 N.

Step-by-step explanation:

La masa es la cantidad de materia que contiene un cuerpo, mientras que el peso es la acción que ejerce la fuerza de gravedad sobre el cuerpo.

El peso se define como el producto de la masa por la aceleración de la gravedad:  

P= m*g

El peso del objeto variará de acuerdo a la fuerza de gravedad que actúa sobre este.

En el Sistema Internacional de Unidades (SI), la unidad del peso se expresa en Newton (N).

En este caso, la masa es 50 kg y la aceleración de la gravedad es 9,8 [tex]\frac{m}{s^{2} }[/tex]. Reemplazando en la definición de peso:

P= 50 kg* 9,8 [tex]\frac{m}{s^{2} }[/tex]

Resolviendo:

P= 490 N

El peso de una persona de 50 kg de masa que se encuentre sobre la superficie del planeta es 490 N.

To figure this out, you can create a ratio. If we say the first 2000 miles is the 1 in the ratio, the ratio would be 1 : 2.5. Since it took 6 minutes for the first 2000, you have to multiply 6 by 2.5 to get your answer of 15 minutes.

Rhombus ABCD has a diagonal BD¯¯¯¯¯.

m∠ADB=(4x−12)°

m∠CDB=(3x+6)°

What is the m∠ADC ?

Enter your answer in the box

º

Answers

Answer:

Solution given:

m∠ADB=(4x−12)°

m∠CDB=(3x+6)°

m∠ADC =?

Since diagonal BD bisect the angle <ADC

so

m∠ADB= m∠ADC

(4x-12)°=(3x+6)°

4x-3x=6-12

x=12+6

x=18°

again.

<ADB=m∠ADB+ m∠ADC=4×18-12+3×18+6=120°

So

the m∠ADC =120°

As it's a rhoumbus angles are equal

m<ADB=m<CDB4x-12=3x+6x=18

m<ADC

4x-12+3x+67x-67(18)-6126-6120°

Place the indicated product in the proper location on the grid.
(2a^x+1/2b^x)^2

Answers

The expression [tex](2a^x + 1/2b^x)^2[/tex] will generally be located towards the upper right quadrant of the grid, with the term [tex]2a^x[/tex] positioned further to the right and the term [tex]1/2b^x[/tex] positioned further towards the top.

To determine the proper location of the expression [tex](2a^x+1/2b^x)^2[/tex] on the grid, let's analyze the components of the expression and their respective positions.

The given expression is [tex](2a^x + 1/2b^x)^2[/tex]. Breaking it down, we have two terms inside the parentheses: [tex]2a^x[/tex] and [tex]1/2b^x[/tex]. These terms consist of variables (a and b) raised to a power (x), along with coefficients (2 and 1/2) multiplying them.

On the grid, we can assign a specific axis for each variable: the horizontal axis for 'a' and the vertical axis for 'b'. The power 'x' indicates that the values will vary along these axes. Since we don't have specific values for 'a', 'b', or 'x', we cannot pinpoint exact locations on the grid.

However, we can make some general observations. The terms [tex]2a^x[/tex] and [tex]1/2b^x[/tex] will have different positions on the grid due to their coefficients. The term with the coefficient 2 will be relatively larger along the horizontal axis compared to the term with the coefficient 1/2, which will be relatively smaller along the vertical axis.

Hence, on the grid, we can expect the term [tex]2a^x[/tex] to be positioned towards the right side, while the term [tex]1/2b^x[/tex] will be positioned towards the top. The exponent '2' outside the parentheses indicates that the entire expression will be squared, so it will be further enlarged.

What is an equation of the line that passes through the points (0, -3)(0,−3) and (-5, 3)(−5,3)?

Answers

Answer:

y = 6/5 x -3

Step-by-step explanation:

Standard equation of a line is expressed as;

y = mx+b

Slope m = y2-y1/x2-x1

Given the coordinates  (0, -3)and (-5, 3)

Slope m = 3-(-3)/-5-0

Slope m = 6/5

Since the line cuts the y axis at y = -3, hence b = -3
