Work out the size of angles a and b. Angle a = Not to scale o o 350 b Angle b=​

Answer:

6,6

There are 8 spaces in bettween  point a and b so 8/2 = 4 so 4 up from point a is 6,6

Step-by-step explanation:

Plantearemos una ecuación cuadratica, y resolviendola veremos que Federico tiene 21 años.

Lo primero que debemos hacer es definir la variable que vamos a usar, en este caso usare:

F = edad de Federico.

Dentro de 11 años, la edad de Federico será:

F + 11

Hace 13 años, la edad de Federico era:

F - 13

Reemplazando eso en lo que el problema plantea, tenemos:

(F + 11) = 0.5*(F - 13)^2

Ahora podemos resolver esto para F.

F + 11  = 0.5*(F^2 - 26*F +169)

F + 11 = 0.5*F^2 - 13*F + 84.5

Movemos todo al mismo lado:

F + 11 - 0.5*F^2 + 13*F - 84.5 = 0

-0.5*F^2 + 14*F - 73.5 = 0

Ahora tenemos una ecuación cuadratica, la cual resolvemos usando la formula de Bhaskara:

[tex]F = \frac{-14 \pm \sqrt{(14)^2 - 4*(-0.5)*(-73.5)} }{2*(-0.5)} =\frac{-14 \pm 7}{-1}[/tex]

Esto nos da dos valores:

El problema con el primer valor, es que es inconsistente con el enunciado, ya que en ese caso, Federico hace 13 años tendría una edad negativa. Así que descartamos la primer solución y nos quedamos con la segunda.

F = 21

Federico tiene 21 años.

The quotient is (2x²+10x-5).

Polynomial is an algebraic expression that consists of variables and coefficients. Variable are called unknown. We can apply arithmetic operations such as addition, subtraction, etc. But not divisible by variable.

Given

[tex]3x^4+6x^{2} +2x^{2} +9x+10[/tex] and [tex]x +2[/tex] polynomials.

The division of [tex]3x^4+6x^{2} +2x^{2} +9x+10[/tex] by [tex]x +2[/tex].

[tex]3x^4+6x^{2} +2x^{2} +9x+10[/tex] and [tex]x +2[/tex] polynomials are given.

[tex]3x^4+6x^{2} +2x^{2} +9x+10[/tex] satisfied by [tex]\rm x = -1,\ -2,\ 0.5,\ 0.5[/tex] . then

Then the equation become

(x+1)(x+2)(x-0.5)(x0.5) then divide the polynomial by x - 3.

[tex]\dfrac{3x^4+6x^{2} +2x^{2} +9x+10}{x+2} = \dfrac{(x+1)(x+2)(x-0.5)(x-0.5)}{x+2} \\\dfrac{3x^4+6x^{2} +2x^{2} +9x+10}{x+2} = (x+1)(x-0.5)(x-0.5)[/tex]

And on multiplication we have,

[tex](x+1)(x-0.5)(x-0.5) = (3^{3} +2x+5)[/tex]

Thus the quotient is [tex](3^{3} +2x+5)[/tex].

Answer:

64 complete snack bags.

Step-by-step explanation:

Brandon has $16 maximum to spend. 16 juices come in a pack for $1.75 per pack, so  16 divided by $1.75 ≈ 9. We want to see how many of those 9  packs of 16 juices we can get into the snack bags, so we need to multiply 16 x 9 = 144 juices.

Alex has $21 maximum to spend. 200 almonds come in a can for $2.59 per pack, so 21 divided by $2.59 ≈ 8. We want to see how many of those 8 cans of 200 almonds we can get into the snack bags, so we need to multiply 200 x 8 = 1600 almonds.

This piece of information was omitted from the original question:

[Brandon and Alex are making snack bags for their soccer club. Each soccer player will get a snack bag that will have 2 juice boxes and 25 almonds.]

Based on this omission, only 2 juice boxes can fit in a snack bag and only 25 almonds respectively. Thus, we divide.

144/2 = 72 juices

1600/25 = 64 almonds

Therefore, there would be 64 complete snack bags that can hold 2 juices and 25 almonds without overflow.

Answer:

x = -7

Step-by-step explanation:

Answer:

y=16.

Step-by-step explanation:

Using substitution requires us to substitute a value in place of another value. Luckily we are given the value of x and can use it in the second equation.

First, we substitute 4 for x.

y=2(4)+8

And then we simply solve.

y=2(4)+8

y=8+8

y=16

:)))

Answer:

[tex]16. - 3 + \frac{p}{7} = - 5[/tex]

[tex] - 3 + p = - 5 \times 7[/tex]

[tex] - 3 + p = - 35[/tex]

Answer:

Step-by-step explanation:

folding line in half not the paper

Answer:  Choice D

Fold the paper so that A is on top of B

Or vice versa

===========================================

Explanation:

M is the midpoint of segment AB.

This means that segments AM and MB are the same length, by definition of what it means to be a midpoint.

We have symmetry going on about point M. When we fold the paper, we're introducing symmetry. Point M will be on the folding line, and the folding line is the perpendicular bisector of AB.

It might help to use dark/heavy ink so that you can see the points on either side of the paper.

You can use the fact that left skewed distribution's graph will have upward values first like a mountain but leaned on left side and then plane low value or no values.

The distribution which is left skewed out of the given distributions is

Option D:  A graph shows the horizontal axis numbered 60 to 100. The vertical axis is numbered 1 to 3. The graph shows an upward then downward trend.

A skewed distribution is a distribution having bias on one of the two sides (either left or right).

It is like leaning mountain on one side(left or right).

A left skewed graph(also called negatively skewed graph) will have upward movement first (and fast) and then downward trend(slowly and sort of elongated)

A right skewed graph(also called positively skewed graph) will have downward movement first(slowly rising) and then upward trend(fast and abrupt like end on the right)

Thus,

The distribution which is left skewed out of the given distributions is

Option D:  A graph shows the horizontal axis numbered 60 to 100. The vertical axis is numbered 1 to 3. The graph shows an upward then downward trend.
