6+24=30

Answer:

B. 5.0 × 10⁻¹² moles per liter.

Step-by-step explanation:

In this exercise we have to calculate the pH levels associated with respective hydrogen ion concentration based on the following formula:

[tex]pH=-\log [H^{+}][/tex]

Where [tex][H^{+}][/tex] is the hydrogen ion concentration, measured in moles per liter.

a) 3.5 × 10⁻¹⁶ moles per liter:

[tex]pH=-\log [3.5\times 10^{-16}][/tex]

[tex]pH \approx 15.456[/tex]

The substance is above the upper bound for alkaline substances.

b) 5.0 × 10⁻¹² moles per liter:

[tex]pH=-\log [5.0\times 10^{-12}][/tex]

[tex]pH \approx 11.301[/tex]

The substance is alkaline.

c) 1.0 × 10⁻⁷ moles per liter:

[tex]pH=-\log [1.0\times 10^{-7}][/tex]

[tex]pH= 7[/tex]

The substance is not acid nor alkaline.

d) 1.1 × 10⁻⁴ moles per liter:

[tex]pH=-\log [1.1\times 10^{-4}][/tex]

[tex]pH \approx 3.959[/tex]

The substance is acid.

Thus, we concluded that correct answer is B.

Answer:

x=-8

Step-by-step explanation:

First you should add 5x+67 and 5x+61 together which is 10x+128

Then you set that equal to 3x+72 which would be: 10x+128=3x+72

After that subtract 3x from both sides which leaves you with: 7x+128=72

Then subtract 128 from 72 which gives you: 7x=-56

Then divide by 7 which gives you x equals negative eight

Answer:

D. y = { -x + 2 x ≥ 1}

          { x + 1  x < 1}

Step-by-step explanation:

First is to eliminate A and C, why?

This is because of the end points shown on the graph.

As shown, if you look at the point of (2,1) it is black, this means that not only is it closed but it is also means ≤ or ≥ symbol.

You are now left with B and D

The difference between these two is the symbols; they are facing the opposite directions.

While B says x ≤ 1, and x > 1

While D says x ≥ 1, and x < 1

The direction of the symbols depends on the direction of the lines and what is part of it (some what like a shaded area)

So you answer would be D

Answer:

x=3

Step-by-step explanation:

Okay so there are 5 small blocks! We need to get 11,but how? 5 + 6 equals eleven can we split 6 into 2? Yes we can. 6 divided by 2 equals 3 therefore our answer is the X represents 3, each tall shape is equivalent to 3 small shapes!

Answer:

What I would do is to basically just find what b equals.

Answer:

22

Step-by-step explanation:

Just plug in

2(15 - 5) + 2 (Solve what's in the parenthesis)

2(10) + 2 (multiply 2*10)

20 + 2 (collect like terms)

22

The evaluation of the expression, 2(a - 5) + 2 when a = 15 is; 22

According to the question;

To evaluate 2(a - 5) + 2. when a = 15.

Answer:

E is the same distance from A and B. ⇒ D

Step-by-step explanation:

Let us explain the meaning of perpendicular bisector

If line m is the perpendicular bisector of line n, then

∵ Line CD is the perpendicular bisector of segment AB

∴ Line CD intersects segment AB at the mid-point of AB

∵ Line CD and segment AB intersected at point E

→ That means E ∈ CD and E ∈ AB

∴ Point E is the mid-point of line AB

∴ Point E divides line AB into 2 equal parts

→ That means point E is at the same distance from points A and B

∴ E is the same distance from A and B.

Answer:

Plug value of the slope and point (2,3) in y= mx+b

3.00 = -6 + b

b= 3 -6

b= 9

So the equation will be
