What is the value of x, the acid concentration of the first solution?
bezimeni [28]

Answer:

A) 0.05

Step-by-step explanation:

Let's summarize into an equation the information we can get from that table.

We have 4 liters of an acid of an unknown concentration, let's call it (4x).

We have 10 liters of an acid with known concentration of 0.40.

And we have a total of 14 liters overall with a concentration of 0.3o.

That's like a weighted average formula: 4x + 10 y = 14z  

Let's replace the concentration values we know and solve this:

4x + 10 (0.4) = 14 * 0.3  

4x + 4 = 4.2

4x = 0.2

x = 0.05

So, the concentration of the 4 liters of acid on concentration X are in fact of concentration of 0.05.

Select all expressions that are equivalent to 4x+2(2x-5)-(3-5x)
Arada [10]

For this case we have the following expression:

4x + 2 (2x-5) - (3-5x)

Applying distributive property to the terms within parentheses taking into account that:

- * + = -\\- * - = +

We have:

4x + 4x-10-3 + 5x =

We add similar terms taking into account that:

Equal signs are added and the same sign is placed.

4x + 4x + 5x-10-3 =\\13x-13

Thus, an equivalent expression is:

13x-13

Answer:

13x-13

Stacy rolls a pair of six-sided fair dice.
Nutka1998 [239]

Answer:

The probability that the sum of the numbers rolled is either a multiple of 3 or an even number is 24/36 = 2/3

The two events are mutually exclusive

Step-by-step explanation:

we first need to create a table of the sample space from the experiment, the sum of the numbers rolled. Find the attached for a depiction of the possible outcomes.

The probability that the sum of the numbers rolled is either a multiple of 3 or an even number will be given by counting the numbers that are either even or multiples of 3 and then dividing by the number of possible outcomes, 36.

In our case this will be;

24/36 = 2/3
