Bob bought a broken motor scooter, repaired it, and sold the scooter for $130. That was $50 less than 1.5 times what he paid for it.
Answer: $120
Step-by-step explanation:
Assume the original price is x.
He sold the scooter for $130 and this was $50 less than 1.5 times what he paid for it.
Relevant formula is therefore:
1.5x - 50 = 130
1.5x = 130 + 50
x = 180/1.5
x = $120

Los puntajes obtenidos por un grupo de alumnos en un examen de 10 puntos son 3,5,2,6,5,9,5,2,8,6. Para saber el puntaje máximo que obtuvo el 75% de los alumnos se debe calcular el
Answer:
Para saber el puntaje máximo que obtuvo el 75% de los alumnos se debe calcular el tercer cuartil.
Step-by-step explanation:
Los Cuantiles (cuartiles, deciles, percentiles) son medidas de localización cuya función es informar del valor de la variable que ocupará la posición (en tanto por cien) que interese respecto de todo el conjunto de variables.
Los cuartiles son medidas estadísticas de posición que tienen la propiedad de dividir la serie estadística en cuatro grupos de números iguales de términos.
El primer cuartil o cuartil inferior es aquel valor de la variable tal que la cuarta parte (25%) de las observaciones son inferiores o iguales a él, y el resto (75%) es superior o igual. El segundo cuartil es la mediana, ya que se trata del valor localizado en la mitad de la distribución. Finalmente, el tercer cuartil o cuartil superior es un valor tal que las tres cuartas partes de las observaciones son inferiores o iguales a él.
En otras palabras, el primer cuartil Q1, es el valor en el cual o por debajo del cual queda aproximadamente un cuarto (25%) de todos los valores de la sucesión (ordenada); El segundo cuartil Q2 es el valor por debajo del cual queda el 50% de los datos (Mediana), el tercer cuartil Q3 es el valor por debajo del cual quedan las tres cuartas partes (75%) de los datos. Es decir, Q1, Q2 y Q3 determinan los valores correspondientes al 25%, al 50% y al 75% de los datos respectivamente. Q2 coincide con la mediana.
Para saber el puntaje máximo que obtuvo el 75% de los alumnos se debe calcular el tercer cuartil.

a triangle where one angle 120 degrees and another 50 degrees
I do not understand what you are asking for
I am assuming you want the missing angle, in this case it is 10
Triangle Sum Theorem states that a triangle is equal to 180 degrees
120+50 = 170
180-170
= 10
When ax3+bx-6 is divided by x+3,the remainder is 9. Find term of a only . The remainder when 2x3-bx2+2ax-4 when it is divided by x-2
Answer:
a) a = - ( 5 + b ) / 9
b) no remainder
Step-by-step explanation:
A) ( ax^3 + bx -6 ) / ( x + 3 )
Remainder = 9
determine the value of a
we will use the result of if ( x + a ) divides polynomial g(x) the remainder is g(a)
therefore given that ( x + 3 ) divides f(x) = ax^3 + bx - 6
= f( -3 ) = 9
= a(- 27 ) - 3b - 6 = 9
= -27a = 9 + 6 + 3b
therefore the term 'a' = - ( 15 / 27 + 3b / 27 )
= - ( 5/9 + b/9 )
a = - ( 5 + b ) / 9
b) Find the remainder when (2x^3 - bx^2 + 2ax - 4 ) is divided by (x-2 )
given that ( x -2 ) divides f(x) = 2x^3 - bx^2 + 2ax - 4
also given a = - ( 5 + b ) / 9 from previous polynomial above
= f(2) = ?
= 2(8) -4b + 4a - 4
= 16 - 4b + 4 ( - ( 5 + b ) / 9 ) - 4
= 16 - 4b + (( -20 - 4b ) / 9) - 4
= 16 - 4b - ( 20 - 4b ) / 9) - 4
= 16 - ( 32b - 20 ) / 9) - 4 = ?
therefore the remainder 'b' = ( -108 + 20 ) / 32 = - 2 3/4
since the remainder is negative there is no remainder then

Write the equation in slope-intercept form for each line based on the information given.
The line has a slope of -1 and goes through the point (2,4).
Answer:
y = -1x + 6 or y = -x + 6
Step-by-step explanation:
First, let's identify what slope-intercept form is.
y = mx + b
m is the slope. b is the y-intercept.
We know the slope is -1, so m = -1. Plug this into our standard equation.
y = -1x + b
To find b, we want to plug in a value that we know is on this line: (2, 4). Plug in the x and y values into the x and y of the standard equation.
4 = -1(2) + b
To find b, multiply the slope and the input of x(2)
4 = -2 + b
Now, add 2 from both sides to isolate b.
6 = b
Plug this into your standard equation.
y = -1x + 6
This is your equation.
Check this by plugging in the point again.
y = -1x + 6
4 = -1(2) + 6
4 = -2 + 6
4 = 4
Your equation is correct.
Hope this helps!

Hakan is standing next to a building whose shadow is 15 feet long. If Hakan is 6 feet tall and is casting a shadow 2.5 feet long, how high is the building?
Height of Building = Feet
answer:
Answer:
36 feet long
Step-by-step explanation:
When you get the question it should look like this: 6/2.5 X/15.
Your gonna have to cross multiply 6 and 15 the keep 2.5 and X like this: 2.5x
After that, it should look like this: 2.5x=90, Now your gonna wanna divide 90 and 2.5 which you will get 36.
X= 36 ft long.

What is the height of a cone with a slant height of 16 inches and a radius of 6 inches? Round your answer to the nearest whole number.
Answer:
14.8 inches
Step-by-step explanation:
Given that:
Slant height, l = 16 inches
Radius, r =. 6 inches
Using the relation :
h² + r² = l²
h² + 6² = 16²
h² = 16² - 6²
h² = 256 - 36
h² = 220
h = sqrt(220)
h = 14.832
h = 14.8 inches
