An ordered pair equation, do you know (x,y)?

The pH of the solution is 12.81.

1) [OH⁻] = 0.065 M

2) [H₃O⁺] = 1.54 x 10⁻¹³ M.

3)  pH = 12.81.

HCl is completely dissociated into its ions in solution:

KOH + H₂O  → H₃O⁺ + K⁺ + OH⁻,

1) [OH⁻] = 0.065 M.

2) [H₃O⁺]:

∵ [H₃O⁺][OH⁻] = 10⁻¹⁴.

∴ [H₃O⁺] = [tex]\frac{10^{-14}}{OH^-}[/tex] = [tex]\frac{10^{-14}}{0.065}[/tex] = 1.54 x 10⁻¹³ M.

3) pH:

Typically, a pH meter is used to measure pH, which converts the difference in electromotive force (electrical potential or voltage) between appropriate electrodes put in the solution under test into pH measurements. A pH meter's basic components are a voltmeter connected to an electrode that responds to pH and an electrode that is constant. The reference electrode is typically a mercury-mercurous chloride (calomel) electrode, however a silver-silver chloride electrode is occasionally used. The pH-responsive electrode is often made of glass.

For strong acids like HCl:

pH = - log[H₃O⁺] = - log[1.54 x 10⁻¹³ M] = 12.81

Answer:

2/5, 8/25, 3/20, 37/100, 24/25

Step-by-step explanation:

A percentage is a ratio or a number expressed in the form of a fraction of 100. Percentages are often used to express a part of a total.

If we know that percentages are fractions of 100, we can convert these percentages:

Simplifying these fractions:

Therefore, the percentages as simplified fractions are listed above.

The system of equations are solved graphically and the value of x and y are -1 and -1 respectively

The equation of a line is expressed as y = mx + b where m is the slope and b is the y-intercept

And y - y₁ = m ( x - x₁ )

y = y-coordinate of second point

y₁ = y-coordinate of point one

m = slope

x = x-coordinate of second point

x₁ = x-coordinate of point one

The slope m = ( y₂ - y₁ ) / ( x₂ - x₁ )

Given data ,

Let the first equation be be P

y = 3x + 2   be equation (1)

Let the second equation be Q

y = -x - 2   be equation (2)

Now , the slope of the line P is m₁ = 3

The slope of the line Q is m₂ = -1

On simplifying the equations , we get

3x + 2 = -x - 2

Adding x on both sides , we get

4x + 2 = -2

Subtracting 2 on both sides , we get

4x = -4

Divide by 4 on both sides , we get

x = -1

Substitute the value of x in equation (1) , we get

y = -3 + 2

y = -1

Hence , the equations are plotted on the graph value of x and y are ( -1 , -1 )

(a)The probability that the selected individual owns shares in the balanced fund is 8%, that is 0.08.

(b)The probability that the selected individual owns shares in a bond fund is 26%.

(c)The probability that the selected individual does not own shares in a stock fund is 57%.

(a) A probability is a number that indicates how likely an event is to occur. In this case, the event is the selected individual owning shares in the balanced fund. The percentage of customers who own shares in the balanced fund is given as 8%. This means that if 100 customers own shares in just one fund, 8 of them would own shares in the balanced fund.

(b) To find the probability that the individual owns shares in a bond fund, we need to add up the percentages of customers who own shares in each of the bond funds:

Short bond: 14%

Intermediate bond: 7%

Long bond: 5%

Total bond funds: 14% + 7% + 5% = 26%

So, the probability that the selected individual owns shares in a bond fund is 26%.

(c) To find the probability that the selected individual does not own shares in a stock fund, we need to find the complement of the probability that the individual owns shares in a stock fund. The probability that the individual owns shares in a stock fund is the sum of the percentages of customers who own shares in each of the stock funds:

Moderate-risk stock: 25%

High-risk stock: 18%

Total stock funds: 25% + 18% = 43%

So, the probability that the selected individual does not own shares in a stock fund is 1 - 43% = 57%.

The measure of angle fge is 53.13°.

The equation used to find the measure of angle fge is the Law of Cosines. The Law of Cosines states that for any triangle, the square of the length of any side is equal to the sum of the squares of the other two sides, minus twice the product of those sides and the cosine of the angle opposite the side.

Using the Law of Cosines, we can solve for the measure of angle fge as follows:

[tex]fge = cos-1((a^2 + b^2 - c^2) / 2ab)[/tex]

For example, if the length of side a is 3, the length of side b is 4, and the length of side c is 5, then the measure of angle fge can be calculated as follows:

fge =[tex]cos-1((3^2 + 4^2 - 5^2) / 2(3)(4))[/tex]

fge = [tex]cos-1(1/6)[/tex]

fge = 53.13°

Therefore, the measure of angle fge is 53.13°.

Answer:

Step-by-step explanation:

To increase a number by a certain percentage, we can multiply the number by (1 + the percentage as a decimal).

To find 25% of 28, we can convert 25% to a decimal by dividing by 100:

25% = 25/100 = 0.25

Now, to find what 28 is increased by 25%, we can multiply 28 by (1 + 0.25):

28 * (1 + 0.25) = 28 * 1.25 = 35

So, the result when 28 is increased by 25% is 35.

Answer: 35

Step-by-step explanation:

we know 28 / 4 = 7

so, 7 is 25% of 28, therefore, we can add 7 to 28 and the answer is 35.

If one could fund the entire federal budget by working a single 8-hour work day, approximately 3,085.35 seconds of that working day would be devoted to paying the amount earmarked for public broadcasting.

Scientific notation is a method of writing extremely large or extremely small numbers. When a number between 1 and 10 is multiplied by a power of 10, it is written in scientific notation.

Here,
To put the amount earmarked for public broadcasting into perspective, we can compare it to the total annual federal budget and calculate how much time would be spent working to pay for it.

First, let's convert both amounts to the same unit of measurement, such as dollars per second. If we assume an 8-hour work day,
8 * 60 * 60 = 28,800 seconds,

Then the federal budget can be funded at a rate of,
= 4.75 × 10¹²/ 28,800 seconds
= 165,278.47 dollars per second.

Next, we can divide the amount earmarked for public broadcasting by the rate of funding to find the number of seconds devoted to paying for it,

= 510 × 10⁶ / 165,278.47 dollars per second
= 3,085.35 seconds

Exterior angles of a right-angled triangle are calculated by the sum of the opposite interior angles. It can also be calculated by using the sum of angles in a triangle, followed by using the sum of angles on a straight line to determine the exterior angles.

Here, m < 1 = 42°, and the other angle is 90°

Thus, if the sum of the two opposite interior angles equals the exterior angles, then:
