Answer:

16.5

Step-by-step explanation:

A is the correct answer

Step-by-step explanation:

If you plug y=x+10 in for the Y variable you just have to solve by multiplying.

1.) It should look like this:

2x + 3(x +10) = 40

2.) You will distribute the three which will make the equation look like this:

2x + 3x + 30 = 40

3.) Add like terms. Then subtract 30 from both sides. Then divide 5 by both sides to get the variable x alone.

but 16.5 is the answer

It's gonna be an irrational number because the length of the hypotenuse is 6.40312....... cm

[tex] {4}^{2} + {5}^{2} = {41}^{2} [/tex]

[tex] \sqrt{41} = 6.403124237[/tex]

An irrational number cannot be written as a simple fraction and the decimals would keep on going without a pattern (if it was repeating, it would be rational).

Answer:

If the legs are equal to 4 cm and 5 cm, respectively we can rewrite the equation 42+52=c2 -> 16+25=41=c^2 so then, c= the square root of 41, which is an irrational number.

Step-by-step explanation:

The equation of the line that passes through the points

(5,-5) and (-5,-1)  is  y=-2/5x-3.

Answer:

a = 84°

b = 36°

c = 24°

d = 84°

e = 132°

Step-by-step explanation:

The parameters of the workers in the office are;

The number of staffs in the office = 60 staffs

The take-aways are pizza, curry, fish & chips, kebab and other

The frequency for the above take-aways = 14, 6, 4, 14, and 22 respectively

The variables for the angles representing the above take-aways on the pie chart = 'a', 'b', 'c', 'd', and 'e'; respectively

In order to find the size of the angles that represent each group of workers in the pie chart, we find the ratio of the group size to the total number of workers and we multiply the result by 360° as follows;

∠a = 360° × 14/60 = 84°

∠b = 360° × 6/60 = 36°

∠c = 360° × 4/60 = 24°

∠d = 360° × 14/60 = 84°

∠e = 360° × 22/60 = 132°

Answer:

The first six terms of the sequence [tex]f\left(n\right)=\left(-3\right)^n[/tex] are:

[tex]-3, 9, -27, 81, -243, 729[/tex]

Step-by-step explanation:

Given the sequence

[tex]f\left(n\right)=\left(-3\right)^n[/tex]

Here [tex]n[/tex] represents any term number in the sequence

Determining the first term

substitute n = 1 in the sequence to determine the first term

[tex]f\left(n\right)=\left(-3\right)^n[/tex]

[tex]\:f\left(1\right)=\left(-3\right)^1[/tex]

[tex]f\left(1\right)=-3[/tex]

Thus, the first term is -3.

Determining the 2nd term

substitute n = 2 in the sequence to determine the 2nd term

[tex]f\left(n\right)=\left(-3\right)^n[/tex]

[tex]\:f\left(2\right)=\left(-3\right)^2[/tex]

[tex]\:f\left(2\right)=9[/tex]

Thus, the 2nd term is 9.

Determining the 3rd term

substitute n = 3 in the sequence to determine the 3rd term

[tex]f\left(n\right)=\left(-3\right)^n[/tex]

[tex]f\left(3\right)=\left(-3\right)^3[/tex]

[tex]f\left(3\right)=-27[/tex]

Thus, the 3rd term is -27.

Determining the 4th term

substitute n = 4 in the sequence to determine the 4th term

[tex]f\left(n\right)=\left(-3\right)^n[/tex]

[tex]f\left(4\right)=\left(-3\right)^4[/tex]

[tex]f\left(4\right)=81[/tex]

Thus, the 4th term is 81.

Determining the 5th term

substitute n = 5 in the sequence to determine the 5th term

[tex]f\left(n\right)=\left(-3\right)^n[/tex]

[tex]f\left(5\right)=\left(-3\right)^5[/tex]

[tex]f\left(5\right)=-243[/tex]

Thus, the 5th term is -243.

Determining the 6th term

substitute n = 6 in the sequence to determine the 6th term

[tex]f\left(n\right)=\left(-3\right)^n[/tex]

[tex]f\left(6\right)=\left(-3\right)^6[/tex]

[tex]f\left(6\right)=729[/tex]

Thus, the 6th term is 729

Therefore, the first six terms of the sequence [tex]f\left(n\right)=\left(-3\right)^n[/tex] are:

[tex]-3, 9, -27, 81, -243, 729[/tex]

From the question, she saved $5 more than twice here usual amount

twice here usual amount is 2 * x = $2x

So, adding the extra $4; the amount saved will be;

2x + 4

The act of factoring is to reduce numbers down to their prime number.

It is a method for dividing a polynomial into pieces that will be multiplied together. At this moment, the polynomial's value will be zero.

A prime number is a positive integer having exactly two factors that are 1 and the number itself. Any number that does not follow this is termed a composite number.

For example:

Let the number 2310, then the factor of the number 2310 will be

2310 = 2 × 3 × 5 × 7 × 11

Where, 2, 3, 5, 7, and 11 are the prime numbers.

Answer:

24 pounds

Step-by-step explanation:

Step 1: Find out how many pens he bought

12 pens per pack

Charles bought 60 packs

60 packs x 12 pens = 720 pens

Step 2: Find out how much Charles spent

2.80 per pack

Charles bought 60 packs

60 x 2.80 = 168 pounds

Step 3: Find out how many pens Charles sold

Charles sold 2/3 of his pens

2/3 x 720 = 480

Step 4: Find out how manypens he sold

Charles sold the pens for 40p

40p x 480 = 19200p

Step 5: Convert pences to pounds

19200p = 192 pounds

Step 6: Find the profit

192 - 168 = 24 pounds

Step 7: Therefore statement

Therefore he mad 24 pounds of profit

128) Los vertices de esta figura son:

(-2,1) (4,1) (4,-2) (0,-3)

129)  Siempre se busca primero la coordenada horizontal! esa es la coordenada en "x"  . Despues es la coordenada  vertical , que es la coordenada en "y" .

 Por lo tanto , para el punto de arriba , la coordenada horizontal  es 1  y la vertical es 3, por lo tanto  la coordenada del punto es (1,3) .

Las coordenadas de los puntos son entonces.

 [tex](1,3)\\(3,0)\\(2-2)\\(-1,-2)\\(-2,1)[/tex]        

130) Las coordenadas del vertice faltante son  (1,-2)    

131) Tenemos que representar un hexágono concavo en el plano cartesiano.

  Un hexágono concavo es un poligono de 6 lados y 6 ângulos, siendo uno de estos últimos mayor a 180 grados.

Podemos dibujar de la siguiente manera: elegir 5 vertices como si fuera un hexágono irregular cualquiera alrededor del origen de coordenadas, y luego elegir a (0,0) como el ultimo vertice. Esta es una de las varias maneras de resolverlo, no la unica .

Como ejemplo, puede ser el siguiente hexágono:

132) Si tenemos los vertices K y L, una forma de  completar un  triangulo isosceles con un tercer vertice es colocar este  vertice en algun punto de la linea perpendicular a KL y que pasa por su punto medio.

Las coordenadas de M, el punto medio de KL se puede calcular como el  promedio de las coordenadas de los extremos K y L:

[tex]Xm=\frac{xK+xL}{2} =\frac{-1+(-1)}{2} =-\frac{2}{2} =-1\\Ym=\frac{Yk+yL}{2} =\frac{2+(-4)}{2} =\frac{-2}{2} =-1[/tex]

Como la linea definida por KL es una  linea vertical, sus lineas perpendiculares seran lineas horizontales. Entonces ,la recta y=-1 es perpendicular a KL y passa por el punto medio de KL.

Cualquier vertice con coordenadas (x,-1), excepto (-1,-1) , formaran un triangulo isosceles.

Como ejemplo , seleccionemos un vertice en (5,-1):

Como tenemos un eje de  simetria en y=-1 , el triangulo KLM es isosceles.

132) Si tomaremos el ejemplo anterior y nos corrieramos del eje de simetria  obterndriamos un triangulo escaleno, es decir, con 3 lados con distintas longitudes.

NOTA: Tener cuidado que por casualidad no coincidan KM o LM con KL (longitud 6).

Por ejemplo, si corremos M hasta (5,0) obtendremos un triangulo isosceles, dado que el segmento KM tendria  longitud 6, al igual que KL.

Para asegurarnos que los tres lados tengan longitudes diferentes, formamos un triangulo rectangulo con dos catetos con diferentes longitud. Un cateto es KL, de longitud 6, y el otro cateto sera KM , de longitud 3 si colocamos a M en (2,2):

The geometric mean should be rounded to one more decimal place than the original data. If the original data were mixed, round to one decimal place more than the least precise.

4.9

Answer: 4.8x+3

Step-by-step explanation:

The portion of the phone that is not occupied by the screen is 4.9x + 3 cm².

For each three-dimensional geometrical shape, surface area and volume are determined. The area or region that an object's surface occupies is known as its surface area. Volume, on the other hand, refers to how much room an object has. There are numerous shapes and dimensions in geometry, including sphere, cube, cuboid, cone, cylinder, etc. Each form has its own volume and surface area. Nevertheless, we can only estimate the area that two-dimensional figures like a square, circle, rectangle, triangle, etc. cover; there is no volume available.

As per the given data:

The width of the screen = x cm

Height of the screen = 1.9 times the width = 1.9x

Dimensions of the phone are given in the diagram.

The area of the screen = height × width

= 1.9x × x = 1.9x² cm²

The area of the phone = (1.9x + 3)(x + 1)

= 1.9x² + 1.9x + 3x + 3

= 1.9x² + 4.9x + 3 cm²

Area of the phone not occupied by screen:

= area of the phone - area of the screen

= 1.9x² + 4.9x + 3 - 1.9x²

= 4.9x + 3 cm²

Hence, the portion of the phone that is not occupied by the screen is 4.9x + 3 cm².
