Answer: 4 horas

Step-by-step explanation:

Una semana (de lunes a viernes) contiene 5 días

Si se entrena 1 hora por día:

1 x 5 = 5 horas (total de horas de entrenamiento de lunes a viernes)

Ese total más el número de horas que se entrena el sábado (x) dividido por 6 (numero de días en la semana incluyendo sábado) debe ser igual a el promedio de horas entrenadas en los 6 días (1.5)

(5+x) /6 =1.5

Despajando x:

5+x =1.5 x 6

5+x =9

x =9-5

x = 4 horas

#6: Tell whether the function below is 1 point<br> linear or exponential.<br> *<br> f(x) = -1/4x + 5
Pachacha [2.7K]

Answer:

Linear function

Step-by-step explanation:

Given

f(x) = -\frac{1}{4}x + 5

Required

Linear or Exponential

A linear equation has the form: f(x) = mx + c;

An exponential has the form: f(x) = ab^x

By comparing both functions to: f(x) = -\frac{1}{4}x + 5

The linear function is similar to f(x) = -\frac{1}{4}x + 5

<em>Hence, the given function is a linear function.</em>

<h2>Options A, B and C are correct choices. :) !!</h2>

Step-by-step explanation:

We have been given that Mael 15 ml of bleach with 3.75 liters of water to make a sanitizing solution for a daycare.

Let us see our given options one by one to find which could be combinations of volumes of bleach and water for Mael's sanitizing solution.

Let us compare our given volume proportions with volume proportion of Mael's sanitizing solution.  

A. 12 ml bleach and 3 liters of water.

We can see that both proportions are equal, therefore, option A is a correct choice.

B. 6 ml bleach and 1.5 liters of water.

We can see that both proportions are equal, therefore, option B is a correct choice.

C. 3 ml bleach and 0.75 liters of water.

 

We can see that both proportions are equal, therefore, option C is a correct choice.

D. 20 ml bleach and 5.5 liters of water.

 

We can see that our both proportions are not equal, therefore, option D is not a correct choice
