Correct question:
The height of a right cylinder is 3 times the radius of the base. The volume of the cylinder is 242 cubic units.
Answer:
6 units
Step-by-step explanation:
Let, radius, r = x
Height, h = 3x
Volume, V = 24π
Volume of cylinder = =πr²h
24π = π * x² * 3x
24π = π* 3x³
24 = 3x³
24 / 3= x³
8 = x³
x = 2
Height, h = 3x
h = 3(2) = 6 units

Which number line shows the solutions to n> 0?
Answer:
Choice A
Step-by-step explanation:
There should be an open circle at 0 since there is no equals in the inequality
n is greater than zero so the line goes to the right.
Choice A

3. Seleccione la gráfica correspondiente a la función de la forma Y=mX , encerrando en una circunferencia el literal correcto:
1)
2)
3)
4)
Answer:
La respuesta esta abajo
Step-by-step explanation:
La pregunta no está completa porque no contiene gráficos, pero te mostraré cómo responderla.
La ecuación de un gráfico de línea recta viene dada por:
y = mx + b; donde y y x son variables, m es la pendiente de la gráfica y b es la intersección en y (que es el valor de y cuando x es 0)
Dado que la ecuación de la gráfica es y = mx, comparando con la ecuación de una línea recta (y = mx + b), podemos concluir que la gráfica con una ecuación y = mx, tiene una pendiente de my una intersección con y de 0.
Esto significa que la gráfica pasa por el origen sin tocar el eje y. Además, la gráfica tiene una pendiente positiva.
Which is an equation for the inverse of y = 4x – 2?

RE
O y=-2x + 4
Answer:
[tex]y=\frac{x+2}{4}[/tex]
Step-by-step explanation:
First, switch the x and the y
[tex]x=4y-2[/tex]
Then add 2 to each side
[tex]x+2=4y[/tex]
Divide 4 to each side
[tex]\frac{x+2}{4}=y[/tex]
The inverse equation of [tex]x=4y-2[/tex] is [tex]y=\frac{x+2}{4}[/tex]
The equation for the inverse of y = 4x - 2 is:
y = (x + 2) / 4
What is a function?A function has an input and an output.
A function can be one-to-one or onto one.
It simply indicated the relationships between the input and the output.
Example:
f(x) = 2x + 1
f(1) = 2 + 1 = 3
f(2) = 2 x 2 + 1 = 4 + 1 = 5
The outputs of the functions are 3 and 5
The inputs of the function are 1 and 2.
We have,
To find the equation for the inverse of y = 4x - 2, we can follow these steps:
Step 1:
Replace y with x and x with y.
x = 4y - 2
Step 2:
Solve for y.
x + 2 = 4y
y = (x + 2) / 4
Step 3:
Write the equation for the inverse.
The inverse of y = 4x - 2 is:
x = (y + 2) / 4
or
y = 4x - 2 can be rewritten as x = (y + 2)/4.
Therefore,
The equation for the inverse of y = 4x - 2 is:
y = (x + 2) / 4

Answer:
Step-by-step explanation:
6. Soil volume = area * height = 1/2*4*4*2.5 = 20 cubic ft
7. Concrete volume = length * width * height = 1.8*1.8*3 = 9.72 cubic ft
Block weight = 95*9.72 = 923.4 lb
8. It is unclear but let's assume the ramp consists of 5 pieces.
The total area = 4*6+3.5*(4+6+7.2) = 84.2 sq ft
So it will require a minimum of 85.2/(4*2) = 10.65 or 11 sheets of plywood
Answer:
Step-by-step explanation:
the skateboard ramp only needs 3 pieces: 2x triangle of 4' by 6' and 1x rectangle of 3.5' by 7.2'.
the 2x triangle require 4x6/4x2 = 3 sheets of plywood
the rectangle require 3.5x7.2/4x2 = 3.15 ~4
so minimum is 7 sheets

what is the value of Q
Answer:
70
Step-by-step explanation:
The three angles should add to 180 degrees because they come from the same straight line. So 180-52-58=70.
Answer:
∠q = 70
Step-by-step explanation:
Angles formed on a straight line add up to equal 180°
Thus, 180 = 52 + 58 + q
52 + 58 = 110
180 = 110 + q
180 - 110 = 70
Hence, q = 70
