Part A: The final volume of the new solution is 150 mL.

Part B: The concentration of the new solution is 0.125 M.

The volume of liquid is defined as the amount of liquid in a three-dimensional container. Volume is the quantity of three-dimensional space occupied by a liquid.

Given that the molarity of NaCl solution is 0.150 M, the volume of NaCl solution is 125 mL, the volume of water added is 25 mL.

Part A:

The final volume of the new concentrated solution is calculated as given below.

[tex]V = 125 + 25[/tex]

[tex]V = 150 \;\rm mL[/tex]

The final volume of the new solution is 150 mL.

Part B:

The mole of the NaCl solution is calculated using the molarity formula.

Molarity of NaCl solution = 0.150 M

Volume of NaCl solution = 125mL or 0.125 L

Molarity = Mole of NaCl solution / Volume of the NaCl solution

[tex]0.150 = \dfrac {Moles}{Volume}[/tex]

[tex]0,150 = \dfrac {Moles}{0.125}[/tex]

[tex]Moles \;= 0.01875[/tex]

The moles of NaCl solution is 0.01875 mole which remains same when water is added. Thus, the molarity of the new concentration can be calculated as given below.

Molarity = Moles of NaCl / Volume of new solution

Molarity = [tex]\dfrac {0.01875}{0.150}[/tex]

Molarity = 0.125 M

Hence we can conclude that the concentration of the new solution is 0.125 M.

Answer:

x = 2[tex]\sqrt{6}[/tex]

Step-by-step explanation:

Using Pythagoras' identity in the right triangle

x² = ([tex]\sqrt{12}[/tex] )² + ([tex]\sqrt{12}[/tex] )² [ the 2 legs are congruent ]

x² = 12 + 12 = 24 ( take square root of both sides )

x = [tex]\sqrt{24}[/tex] = [tex]\sqrt{4(6)}[/tex] = [tex]\sqrt{4}[/tex] × [tex]\sqrt{6}[/tex] = 2[tex]\sqrt{6}[/tex]

Answer:

1. Ursula = y

2. Alma = y - 3 (3 meters behind)

3. Carly = y - 6 (3 meters behind Alma)

4. Lani = y - 8 (2 meters behind Carly)

5. Isabel = y - 10 (2 meters behind Lani)

6. Betty = y - 12 (2 meters behind Isabel)

Step-by-step explanation:

We are going to use different letters to represent the meters run by the girls:

Alma beat isabel by 7 meters, if A is x then Isabel is x - 7

A = x

I = x -7

Ursula beat  Betty be 12 meters. Let's call Ursula y, then:

U  = y

B = y - 12

Alma finished 5 meters ahead of Lani but 3 meters behind Ursula. Let's call Lani z.

L = z

A = z + 5 = y - 3 (since Ursula was "y" and Alma finished 3 meters behind Ursula)

We're going to leave Carly until the end since she finished halfway between the first and the last girls.

Now we can see that Alma is represented by equations with 3 different letters:

A = x = z + 5 = y -3

Therefore we know that

x = y -3

⇒A = y - 3

And we'll proceed to express all the other girls distances in terms of "y"

We know that Isabel = x - 7. Therefore we can substitute x = y - 3 and we get that

Isabel = x - 7 = (y - 3) - 7 = y - 10

⇒I = y - 10

We already have Ursula and Betty expressed in terms of y.

⇒U = y

⇒B = y - 12

Now let's go back to Alma equation (A = x = z + 5 = y -3) and we see  that:

z + 5 = y - 3.

Therefore z = y - 3 - 5 = y - 8.

⇒z = y - 8

We have Lani left who was L= z = y - 8

⇒ L = y - 8

The first girl would be Ursula = y

And the last girl would be Betty = y - 12.

⇒Therefore, Carly finished halfway them both and that would be C = y - 6

So, the order in which they arrived was:

Ursula = y

Alma = y - 3 (3 meters behind)

Carly = y - 6 (3 meters behind Alma)

Lani = y - 8 (2 meters behind Carly)

Isabel = y - 10 (2 meters behind Lani)

Betty = y - 12 (2 meters behind Isabel)

Answer:

Step-by-step explanation:

x + 70 = 180   {Linear pair}

       x = 180 - 70

       x = 110

y + 82 = 180 {linear pair}

      y = 180 -82

      y = 98

x - 4 = 110 - 4 = 106

2y - 40 = 2*98 - 40

            = 196 - 40

            = 156

Sample size is the number of subjects that are included in research or survey. The sample space for this action is CC, CA, AC, and AA.

Sample size can be defined as the number of subjects that are included in research or survey.

As it is given that there are two customers, and each of the customers buys any one of the two tickets, a classic ticket (C), or an autograph event ticket (A).

Now, as each of the customers has two choices, therefore, the sample space for this action can be written as,

CC - When both of the customers buy a classic ticket.

CA - When the first customer buys a classic ticket(C) while the other buys an autograph event ticket (A).

AC - When the first customer buys an autograph event ticket (A) while the other buys a classic ticket(C).

AA - When both of the customers buy an autograph event ticket (A).

Hence, the sample space for this action is CC, CA, AC, and AA.

Answer:

70 inches²

Step-by-step explanation:

We can break this shape up into 5 different shapes.

Two triangles, and three rectangles.

The three rectangles will be A = L * W and are all the same size,

A = L * W

A = 3(L * W)

A = 3(10 * 2)

A = 3(20)

A = 30 inches²

Now, we need to find the area for the two triangles. Usually, you would take the base times the height and divide by two, but since we have two triangles of the same size we do not need to divide by two,

A = B * H

A = 10 * 4

A = 40 inches²

Last, we will add the two areas for the triangles and rectangles together,

40 inches² + 30 inches² = 70 inches²

Answer: Triangle 3
