It would take 21 8/ 12 seconds to fill 2 tires

Proportion can be defined as the comparison between two numbers or elements

It is also an equation with two ratios draw equal to each other.

From the information given,

If 31/ 3 tires (10/ 3 ) tires is filled in 3 1/4 seconds ( 13/ 4)

Then 2 tires = x seconds

cross multiply

x = 13 / 4 × 2 ÷ 10/ 3

x = 26/ 4 × 3/ 10

x = 260/ 12

x = 21 8/ 12 seconds

Thus, it would take 21 8/ 12 seconds to fill

The percentage of the company’s employees are both female and over 6 feet tall is 3.75%

Let the total number of employees in the given company be x. So, the number of female employees in the company are : 75% × x

Number of female employees in company = 0.75x

Now, calculating number of female employees that over 6 feet tall = 0.75x × 5%

The number of female employees that over 6 feet tall = 0.0375x

Percentage of the company’s employees are both female and over 6 feet tall = percentage of female and tall employees ÷ total number of employees × 100

Percentage of the company’s employees are both female and over 6 feet tall = (0.0375x÷x)×100

Percentage of the company’s employees are both female and over 6 feet tall = 3.75%

Therefore, the percentage of the company’s employees are both female and over 6 feet tall is 3.75%

You can make 106.67 L of 25% v/v acid solution by mixing 6.67 L of pure acid with 100 L of 20% v/v acid solution.

Acids are a type of chemical that can either absorb electrons or give off protons or hydrogen ions. An anion and a cation can form in water when a hydrogen atom that is bonded to an acid releases (dissociates). How acidic a substance is and how acidic its solution pH is depends on how many hydrogen ions it produces.

The word acid stems from the Latin words acidus or acere, which suggest "sour," because one of the characteristics of acids in water is a sour taste (e.g., vinegar or lemon juice).

How thoroughly an acid splits into its ions after being dissolved in water indicates whether it is strong or weak. A strong acid, like hydrochloric acid, completely dissociates into its ions in water.

100 liters * (20/100) = 20 liters acid

Let's assume that the number x represents the amount of pure acid you need to add to your initial solution. The volume of acid will increase by x because you are working with pure acid.

V(acid) = 20 +x

V(solution) = 100+ x

As a result, the percent concentration by volume of the target solution will be equal to

{V(acid)/V(solution)} * 100 = 25%

{(20+x)/(100+x)} * 100 = 25%

(20 +x) 100 = 25(100+x)

2000+100x = 2500 + 25x

75 x = 500

x = 6.67 liters

A committee of size less than or equal to n can also be formed with a chairperson by selecting the chairperson first, followed by the members of the committee. The chairperson can be chosen from among n options. The picker has two options for the remaining n-1 individuals: to include them or not.

The  measures are possible for the other two angles are 70 degrees respectively

An isosceles triangle is a triangle that has 2 of its sides and angles to be equal.

Let the measure of the other possible angles be x and y such that x = y

Since the sum of angle in a triangle is 180 degrees, hence;

x+y +40 = 180

x+x+40=180

2x+40=180

2x=180-40

Answer:

I think that the answer is D.

Step-by-step explanation:

Using the distance between two points formula to calculate the side lengths, it is found that the figures are not congruent.

Congruent figures are figures that have the same outer side lengths.

We are given the vertices for this problem, hence we use the distance between two points formula to calculate the lengths.

Suppose that we have two points, [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex]. The distance between them is given by:

[tex]D = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

This formula is derived from the Pythagorean Theorem, as the points form a right triangle in the xy-plane, with the hypotenuse being the distance between them.

For Triangle LMK, the side lengths are given as follows:

For Triangle XYW, the side lengths are given as follows:

Due to different side lengths, the figures are not congruent, and nothing can be stated about the transformations that were used.

3x² - 1 = 0

3x² = 1

x² = 1/3

x = ±√(1/3)

  = -1/√3, 1/√3.

So, -1/√3 is a zero of 3x² - 1 .

Yes, x = -1/√3 is a zero of the polynomial 3x² - 1 because substituting the value results in zero, confirming its solution to the equation.

To verify whether x = -1/√3 is a zero of the polynomial 3x² - 1, we need to substitute this value into the polynomial and check if it results in zero.

Given polynomial: 3x² - 1

Now, substitute x = -1/√3 into the polynomial:

3(-1/√3)² - 1

Now, simplify:

3(1/3) - 1

1 - 1

The result is zero. Since the expression evaluates to zero when x = -1/√3, this means that x = -1/√3 is indeed a zero of the polynomial 3x² - 1.

The point (1,1) represents 1+i in the two dimensional complex plane. Absolute value of 1+i = [tex]\sqrt{2}[/tex].

Given the complex number, z = 1+i

The general form of a complex plane is x+iy, where x and y are real numbers.

We can place any complex number into a two-dimensional complex plane with two axes - X and Y.

For z = 1+i, x = 1 and y = 1. So the point (1,1) will represent z = 1+i in the two dimensional complex plane.

The absolute value of a complex number z = x+iy is given by ,

The measure of angle J is 116°

Linear pair of angles are angles formed when two lines intersect at a single point.

Angles are said to be linear if they are adjacent to each other with the intersection of the two lines.

Note that the sum of angles of a linear pair is equal to 180°.

From the information given, we have that;

But we have the expression as;

Angle R + Angle J = 180°

substitute the values into the equation

3x - 5 + 5x + 1 = 180°

collect like terms

8x - 4 = 180°

8x = 180 + 4

8x = 184

To determine the value of x, divide both sides by the 8

8x/8 = 184/8

Divide through

x = 23

But we have that;

Angle J = 5x + 1

Angle J = 5(23) + 1

Angle J = 115 + 1

Angle J = 116°

Thus, the measure of angle J is 116°
