A friend and I disagree about the answer to the simple math question posed by this post on social media, can you give me the correct answer. I think it's 35, she says 70.

Answer:

4 13/20 -> 4.65

Step-by-step explanation:

Well if you mean 4 and 13/20 then your answer is 4.65

IF you mean just 13/20 then your answer is just 0.65

Answer:

The highest height the ball achieves is 4.5125 meters.

Step-by-step explanation:

Vertex of a quadratic function:

Suppose we have a quadratic function in the following format:

[tex]f(x) = ax^{2} + bx + c[/tex]

It's vertex is the point [tex](x_{v}, y_{v})[/tex]

In which

[tex]x_{v} = -\frac{b}{2a}[/tex]

[tex]y_{v} = -\frac{\Delta}{4a}[/tex]

Where

[tex]\Delta = b^2-4ac[/tex]

If a<0, the vertex is a maximum point, that is, the maximum value happens at [tex]x_{v}[/tex], and it's value is [tex]y_{v}[/tex].

In this question:

Quadratic function [tex]y = -0.2x^2 + 1.9x[/tex], which has [tex]a = -0.2, b = 1.9[/tex].

The maximum height of the ball is [tex]y_{v}[/tex].

Then

[tex]\Delta = b^2-4ac = (1.9)^2 - 4*(-0.2)(0) = 3.61[/tex]

[tex]y_{v} = -\frac{3.61}{4(-0.2)} = 4.5125[/tex]

The highest height the ball achieves is 4.5125 meters.

Answer: 9 years old

Step-by-step explanation:

The parts

Moosa= x

Moosa's sister = (3x-6)

and together x+(3x-6)=30

Solve for x to get 9 which means Moosa is 9 and Moosa's sister (older) is 21

area of circle = pi (3.142) x 9squared

answer 254.5 or 81 pi

Answer:

I think its 6 units

Step-by-step explanation:

The area is 30 units so therefore you would divide it by any side so therefore if you would do 30 divided by 5 you would get 6.

Answer:

its clearly 77

Answer:

The two numbers are - 12 and - 12 .

Step-by-step explanation:

Let the two numbers be x and y then

By the question

x * y = 144

or x = 144 / y ....... I)

Again

x + y = - 24

Or 144/y + y = - 24

or, ( 144 + y²) / y = - 24

or, 144 + y² = - 24y

y² + 24y + 144 = 0

y² + ( 12 + 12 ) y + 144 =0

y² + 12y + 12y + 144 = 0

y(y + 12 ) + 12 ( y + 14) = 0

( y + 12 ) ( y + 12 ) = 0

Either

y + 12 =0

y = - 12

Now

x = 144 / - 12 = - 12

Therefore the two numbers are - 12 and - 12 .

The statement is true about the shown figures "Trapezoid ABCD has been dilated using O as the center". which is the correct answer would be an option (A).

A point is transformed when it is moved from where it was originally to a new location. Translation, rotation, reflection, and dilation are examples of different transformations.

here, we have,

A dilation is a transformation that generates an image with the same shape as the original but a different size. The dilation center is a fixed point in the plane. The initial figure is stretched or shrunk through dilatation.

As per the given figures,

Trapezoid ABCD has been expanded to trapezoid A'B'C'D' around the dilation center O. When the figure is expanded, the scale factor exceeds one.

Thus, the statement is true about the shown figures "Trapezoid ABCD has been dilated using O as the center".

Hence, the correct answer would be option (A).

Answer:

x = 46

Step-by-step explanation:

Hello there!

The following angles are corresponding angles

One of the properties of corresponding anlges is that they are congruent

That being said we can use this equation to solve for x

2x + 4 = 4x - 88

step 1 subtract 2x from each side

2x -2x cancels out

4x - 2x = 2x

now we have

4 = 2x - 88

step 2 add 88 to each side

-88 + 88 cancels out

4 + 88 = 92

now we have 92 = 2x

step 3 divide each side by 2

92 / 2 = 46

2x/2= x

we're left with x = 46

The mass of each bag of flour is 2 kg.

In physics, mass is a quantitative measure of inertia, which is a fundamental property of all matter. In the International System of Units, a kilogram is a unit of mass (SI).

Given that the mass of each bag of rice is 1.2 kg. We can see that there are 5 and 3 bags containing rice and flour respectively. First, we have to calculate the total weight of the right side of the weight machine. Then we equate it with the total weight of the left side of the weight machine.

Let, the mass of each bag of flour be y kg.

Now,

Weight of the right side = Weight of the left side

i.e. number of rice bags × mass of rice bags = no. of flour bags × mass of flour bags

i.e. 5 × 1.2 = 3 × y

i.e. 3y = 6.0

i.e. y =6/3=2

So, the mass of each bag of flour is 2 kg.

Pregunta completa:

En un parque hay una tienda donde se alquilan patines a 0,50 € la hora; Patinetas a 1 € la hora y bicicletas a 2 € la hora. ¿Cuál es la ecuación de los costos en función del tiempo empleado en cada uno de los casos?

Respuesta:

C (t) = 0,50 billones de euros; C (t) = € t; C (t) = 2 billones de euros

Explicación paso a paso:

Dada la siguiente tarifa de alquiler:

Patines = 0,50 € por hora

Patinetas = 1 € por hora

Bicicletas = 2 € la hora

La ecuación de costo en función del tiempo en cada caso se puede expresar como:

Costo en función del tiempo; Connecticut)

Donde, t = tiempo

Costo, C (t) = costo por hora * Número de horas

C (t) para patines:

C (t) = 0,50 t €

Costo ; C (t) para patinetas:

C (t) = € t

Costo ; C (t) para bicicletas;

C (t) = 2 billones de euros
