Answer:

The number -0.39 ml could be added to 0.40 ml for the level of precision to be 0.01ml.

Step-by-step explanation:

Let x be the number could be added to 0.40ml .

According to question

If the number x added to 0.40 ml then we get precise  level 0.01 ml .

therefore, we make an equation by using of  addition property

      x+0.40=0.01

    x=0.01-0.40

Because when we put a number from left hand side of equal to and put  on right hand side of equal to then the sign of the number changes .

therefore, sign of 0.40 changes in to negative .

Therefore, by solving equation

       we  get x= -0.39

<h3>Hence, -0.39ml  is the number that could be  added to 0.40ml for the level of precision to be 0.01 ml.</h3>

Ana escribe conjuntos de cinco enteros positivos consecutivos con la siguiente propiedad: La suma de tres de los números es tan
Keith_Richards [23]

Answer:

a) 1.

Step-by-step explanation:

Supongamos que el primer número entero positivo es a tal que a ∈ Z⁺.

Luego, el conjunto de los cinco enteros positivos se puede expresar como

A = {a; a+1; a+2; a+3; a+4}

Dada la condición del problema, se debe cumplir que

a + (a+1) + (a+2) = (a+3) + (a+4)

⇒  3a + 3 = 2a + 7

Resolviendo la ecuación resulta

a = 4

Luego, el conjunto A nos resulta

A = {4; 5; 6; 7; 8}

Puede concluirse que sólo un conjunto cumple con esta condición.
