How to determine the pH of the coffee?

pH is a measure of hydrogen ion concentration, a measure of the acidity or alkalinity of a solution

Given:  The formula pH= -log₁₀ C,

where is the concentration of hydronium ions in the solution measured in moles per litre

The concentration(C) of Hydronium ions type of coffee is 1.3 x 10⁻⁵ moles per liter

To calculate the pH, we will substitute the value of the concentration (C) into the given formula:

pH= -log₁₀ C                     (C = 1.3 x 10⁻⁵ moles per liter)

pH = -log₁₀(1.3 x 10⁻⁵) = 4.89

In the proportional relationship table, x would represent distance and y, weight.

The complete table is given in the explanation below.

What is a Proportional Relationship?

If two variables that have quantities that vary proportionately are x and y, then the constant of proportionality that lies between both varies can be calculated as k = y/x. The equation for the proportional relationship would be expressed as y = kx.

x represents distance (cm)

y represents weight (newtons).

Using the pair of value that is given in the table, (20, 28), the constant of proportionality, k, would be:

k = y/x = 28/20

k = 1.4

The equation would be y = 1.4x.

Use the equation to complete the table by substituting the value of each missing variables:

Row 2, when x = 55:

y = 1.4(55)

y = 77

Row 3, when y = 140:

140 = 1.4x

140/1.4 = x

100 = x

x = 100

Subtract 2 from both sides :

b = 5

Let's check :

Correct

Hope this helped and have a good day

Answer:

b = 5

Step-by-step explanation:

to solve this you must first combine like terms

-8b + 2 + 6b = -3b + 7

combine (add) -8b and 6b

that makes -2b

-2b + 2 = -3b + 7

now add 3b to both sides to put b on one side

-2b + 2 + 3b = -3b + 3b + 7

b + 2 = 7

now subtract 2 to both side

b + 2 - 2 = 7 - 2

A (b)=12. B+9/2 which equation represents the inverse function b ( a which takes the trapezoids areas and put and returns as output the length of the other base

Answers

Answer:

B(a) = a/6 - 9

Step-by-step explanation:

The equation that represents the function B(a) as the length of the side parallel to the base is B(a) = a/6 - 9, as per the area of a trapezoid.

What is the area of a trapezoid?

If the length of two parallel sides of a trapezoid is 'a', 'b' and the height of that trapezoid is 'h', then the area of a trapezoid can be represented as

= [(a + b)h]/2

Given, the base of the trapezoid is 9 and the height of the trapezoid is 12.

Therefore, 'b' is the parallel side of the base.

The given function that represents the area of the trapezoid is:

A(b) = [12(b + 9)]/2

Let, A(b) = a.

Therefore, a =  [12(b + 9)]/2

⇒ 2a = 12(b + 9)

⇒ a = 6(b + 9)

⇒ a = 6b + 54

⇒ 6b = a - 54

⇒ b = (a - 54)/6

⇒ b = a/6 - 9

If we assume the length of the side parallel to the base 'b' = B(a), therefore, the equation will be:

B(a) = a/6 - 9

The dimensions of a rectangle are 6x-7 and 3x-1. what is the area in square feet?
please help fast!!

Answers

The area of the rectangle is given by the formula below:

A = 18x^2 - 27x + 7

What is the area of the rectangle?

For a rectangle of width W and length L, the area is given by the formula:

A = W*L

Here we know that the dimensions of a rectangle are 6x-7 and 3x-1, then we can define:

L = 6x - 7

W = 3x - 1

Replacing that in the area formula above we will get:

A = (6x - 7)*(3x - 1)

Now we can expand that product:

A = (6x)*(3x) + (6x)*(-1) + (-7)*(3x) + (-7)*(-1)

A = 18x^2 - 6x - 21x + 7

A = 18x^2 - 27x + 7

Answers

The number of yes votes on whether to raise property taxes, using proportions, was of 3345, considering that 6183 total votes.

What is a proportion?

A proportion is a fraction of a total amount, and equations are built with these fractions and the rates in the context of a problem to find the desired measures in the problem using basic arithmetic operations such as multiplication and division.

One application of proportions is for ratio problems, as one ratio between two amounts a and b is given by the division of a by b, and over the total, these rates are:

Fraction of a: a/(a + b).Fraction of b: b/(a + b).

The ratio of yes votes to no votes was 5 to 4, hence the fraction of yes votes is given as follows:

5/(5 + 4) = 5/9.

The total number of votes was of 6183, hence the number of yes votes is calculated as follows:

Answers

The budget of KT's Restaurant for newspaper advertising for the coming year is $58,533,500

Given,

The length of advertisement of KT's Restaurant in Vidalia Times in week days = 5,000

The length of advertisement of KT's Restaurant in Vidalia Times in Saturdays = 10,000

The cost of daily column = $27.55 per column inch

The cost of Saturdays = $29.35 per column inch

We have to find the budget of KT's Restaurant for newspaper advertising for the coming year;

Here,

There are approximately 53 Saturdays in a year.

So,

365 - 53 = 312

Then,

The budget of advertisement on daily column = 312 × 5000 × 27.55 = $42,978,000

The budget of advertisement on Saturday column = 53 × 10,000 × 29.35 = $1,555,500

Juan must add a volume of 7 cubic feet for the enlarged sandbox.

How much sand must we add to an enlarged sandbox?

The volume occupied by the sandbox (V), in cubic feet, is represented by the volume formula for a parallelpiped:

V = w · l · h

Where:

w - Width, in feetl - Length, in feeth - Height, in feet

Juan wants to know the additional amount of sand required for the enlarged sandbox. If we know that the initial volume is equal to a cubic foot and each length is double, then we find that the resulting volume for sandbox is:

V' = (2 · w) · (2 · l) · (2 · h)

V' = 8 · (w · l · h)

V' = 8 · V

V = 8 ft³
