Answer:
42%
Step-by-step explanation:
The computation of the percentage is shown below:
Here we assume that there are 100 students
So according to the question
60% of the students would pack the lunch i.e. 60 students
And, 40% of the students buy a lunch i.e. 40 students
Now the students who pack the lunch they have 70% of cookie
So, 70% of 60 students = 42 students
Now the percentage is
= 42 students ÷ 100 students
= 42%
En un parque hay una tienda donde se alquilan patines a 0,50€ la hora, monopatines a 1€ la hora y bicicletas a 2€ la hora.
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

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 function y=-0.2x^2+1.9x models the path of a kicked soccer ball.The height is y,the distance is x, and the units are meters.How high does the soccer ball go?
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.

The measure of the third side of the triangle will fall between 5 and 29.
What is the Triangle Inequality Theorem?Triangle Inequality Theorem is that for two sides of a triangle, the third side cannot be equal to or greater than the third side's length.
From the Triangle Inequality Theorem,
The sum of the lengths of any two sides of a triangle must be greater than the third side, then the third side of this triangle must be strictly less than 29.
But we can't make the length of the third side too small, either.
If x is the length of the third side, then x + 12 > 17, which means that x > 5
Therefore, the length of the third side must fall between 5 and 29.
Hence, the measure of the third side of the triangle will fall between 5 and 29.

Each bag of rice has a mass of 1.2 kg.
In kilograms, what's the mass of each bag of flour?
The mass of each bag of flour is 2 kg.
What is mass?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).
How to solve this problem?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.
