the text suggests that one key demographic statistic is the percentage of people in a region that are under 15 years of age. why is this statistic important?

Answer:

Below

Step-by-step explanation:

Picture  is     .12   x  .08  m

    2 m / .08 m = 25

    2.4 m / .12 m = 20    <===== limiting factor   ( 20 is less than 25)

      so it would be   20 * (.12)      X      20(.08)   =  3.84 m^2

Answer:

Rounding down to the nearest whole number, we get 5 stories. The correct answer is, therefore (A) the 5th story.

Step-by-step explanation:

To solve this problem, we need to find the number of stories the ladder can reach by dividing the length of the ladder by the height of each story.

The longest ladder on the fire truck reaches 95 feet, and each story is 18 feet high, so the highest story that the ladder can reach is:

95 feet / 18 feet/story = <<95/18=5.28>>5.28 stories

You represent three consecutive odd integers with x, x + 2 and x + 4

From the question, we have the following parameters that can be used in our computation:

Three consecutive odd integers

As a general rule

Odd integers are integers that cannot be divided by 2

Consecutive odd integers have a difference of 2

This means that the three consecutive odd integers are

x, x + 2 and x + 4

Where the least of the integers is x

The elements in sets are separated by commas so they can be read easily.

Instead of describing the constituents of a set, a set-builder notation describes them. The elements are listed, for instance, in the set {5, 6, 7, 8, 9}. We interpret the collection of all x such that x is a counting number between 4 and 10 as the collection of all x.

In mathematics, a set is a logically arranged group of items that can be represented in either set-builder or roster form. Sets are typically denoted by curly brackets {}; for instance, A = {1, 2, 3, 4} is a set.

The sequence of elements (separated by commas) between the curly braces " and "in mathematics form an unordered group of elements known as a set. For instance, the domesticated animals {cat, cow, dog} , the odd numbers {1, 3, 5, 7, 9} and the alphabets {a, b, c, d, e} are all sets. So they can be read or interpreted easily.

(D) We have justified our answers by using the substitution method.

What is a linear equation in two variables?

An equation is said to be a linear equation in two variables if it is written in the form of ax + by + c=0, where a, b & c are real numbers and the coefficients of x and y, i.e a and b respectively, are not equal to zero.

Let x number of tickets sold on Friday and y number of tickets sold on Saturday.

By using the given condition,

x + y = 360 ----------(I)

y =3x -------(II)

Put y = 3x in equation (I), we get

x + 3x = 360

4x = 360

  x = 90

Now put x = 90 in equation (I), and we get

90 + y = 360

y = 270

Hence, 90 tickets were sold on Friday and 270 tickets were sold on Saturday.

Answer:

one solution because when you isolate the x terms:

2x-3x=0 and you combine like terms

-x=0

and divide by negitive one because -x is (-1)(x)

you get x=0

Step-by-step explanation:

Answer:

One solution

Step-by-step explanation:

It appears this problem has no solution, buttt let's look closer.

2x and 3x are like terms, meaning they can be added and subtracted because they both have x!

So let's combine these like terms and see what we get...

2x = 3x

0 = 3x -2x

0 = 1x

x = 0 / 1

x = 0

The only solution is 0! No other number is possible.

Answer: x=2, y=-8

Step-by-step explanation: there are a couple of different methods you can use, my favourite is substitution

to do this, find a value of x or y from one equation and plug it into the other. let's use x in this case

so we have 13x-6y=22 and x=y+6

for the x value of the first equation, plug in x=y+6 from the second equation to get:

13(y+6)-6y=22

then you solve for y,

13y+78-6y=22

7y=-56

y=-8

then to solve for x, plug in your y value to either of the first 2 equations. lets use x=y+6

so you'd have x=(-8)+6 to give you x=2

4 1/3, 4.337, 35/8, 4.44

Step-by-step explanation:

4.337, 4 1/3, 35/8, 4.44

4 1/3 = 13/3 = 4.333

35/8 = 4.375

So, the order from least to greatest is: 4 1/3, 4.337, 35/8, 4.44

Answer:

4 1/3, 4.337, 35/8, 4.44

Step-by-step explanation:

"order from least to greatest" means put the smallest first and each next one bigger and the biggest one last.

Change everything to decimals to compare.

A fraction bar is just a division symbol.

1/3 means 1÷3 which is .33333...

4 1/3 = 4.33333...

35/8 means 35÷8

= 4.375

Smallest is 4.333...

So 4 1/3 goes first.

Then 4.337 and next 35/8 (bc 4.375)

Last is biggest 4.44 so it goes last.

In order from least to geatest is:

4 1/3, 4.337, 35/8, 4.44

4x + 8y ≤ -24 is the example of linear inequality in two variables.

Linear equations are one-degree equations. It is a straight-line equation. A linear equation with parameters a and b equal to zero has the conventional form ax + by + c = 0.

The graph of a two-variable inequality is the set of points that describe all solutions to the inequality. The coordinate plane is split in half by a boundary line created by a linear inequality, with one-half representing the solutions to the inequality.

It's a line with a shaded side on one side to show which xy pairings are the inequality's solutions.

For example -

Let us take a equation, 4x + 8y ≤ -24

Now, solve the above equation in the form of slope-intercept.

4x + 8y ≤ -24

or, 8y ≤ - 4x - 24

or, y ≤ -(1/2)x - 3

Answer:

D. 12 hours

Step-by-step explanation:

I am guessing that they want you to find the average time together, or the mean.

Add 18 hours and 6 hours together to get 24 hours.

To get the average, you have to divide the total hours by the amount people involved.

Since there are 2 groups (2 people) that have an outcome of 18 hours and 6 hours, 24 hours/2 people is a 12 hour average.

Answer:

Para encontrar a taxa trimestral equivalente à taxa de 1,05% ao mês, basta dividir a taxa mensal por 3, pois um trimestre é composto por 3 meses. Portanto, a taxa trimestral equivalente à taxa de 1,05% ao mês é de 1,05% / 3 = 0,35%.

Para encontrar a taxa anual equivalente à taxa de 1,05% ao mês, basta multiplicar a taxa mensal por 12, pois um ano é composto por 12 meses. Portanto, a taxa anual equivalente à taxa de 1,05% ao mês é de 1,05% x 12 = 12,6%.

2)a) Para calcular a taxa de juros compostos equivalente a uma taxa efetiva de 1% ao mês ao semestre, basta multiplicar a taxa mensal por 6, pois um semestre é composto por 6 meses. Portanto, a taxa de juros compostos equivalente a uma taxa efetiva de 1% ao mês ao semestre é de 1% x 6 = 6%.

b) Para calcular a taxa de juros compostos equivalente a uma taxa efetiva de 1% ao mês ao ano, basta multiplicar a taxa mensal por 12, pois um ano é composto por 12 meses. Portanto, a taxa de juros compostos equivalente a uma taxa efetiva de 1% ao mês ao ano é de 1% x 12 = 12%.

Therefore, the solution to this problem is  (x - 2)(x + 3) are the factors of p(x) (2x - 5).

An equation is a mathematical statement that is created by connecting two expressions using the equivalent sign. An example of an equation is 2x - 5 = 15. By resolving this equation, we may ascertain that the variable x has a value of 5.

Here,

Given, the polynomial in this case is 2x3 - 3x2 - 17x + 30.

It is necessary to factor the polynomial.

Let p(x) equal 2x3, 3x2, 17x, and 30.

P(xconstant )'s term is 30.

Factors of 30 are equal to 1, 2, 3, 5, 6, 10, 15, and 30.

Consider x = 2.

Replace x = 2 in p. (x),

2(2)³ - 3(2)² - 17(2) + 30 =p(2)

=> 2(8) - 34 - 3(4) + 30

= >16 - 16

= 0

So, x - 2 is a factor of 2x³ - 3x² - 17x + 30.

Now splitting the x² and x terms,

2x³ - 4x² + x² - 2x - 15x + 30= 2x³ - 3x² - 17x + 30

=> x(x - 2) - 15(x - 2) +  2x²(x - 2)

= > (x - 2)  *  (2x² + x - 15)

factoring  2[tex]x^{2}[/tex] + x - 15

= 2[tex]x^{2}[/tex] + 6x - 5x - 15

= - 5(x + 3)  +  2x(x + 3)

= (x + 3)(2x - 5)

Therefore, the solution to this problem is  (x - 2)(x + 3) are the factors of p(x) (2x - 5).

As per the rational root theorem, the actual root of the polynomial is  - 5/2

The term polynomial refers the algebraic expression in which the exponents of all variables should be a whole number

Here we have given that  f(x) = 6x⁴ + 5x³ – 33x² – 12x + 20.  and we need to find which is an actual root of f(x).

In order to find the root for the polynomial we have to apply each value as the replacement of x in the polynomial.

And then we have to find in which one makes the polynomial result as zero.

First we have to take the value of x as -5/2, then the polynomial equation be like,

Here we have to substitute x=-5/2, then we get

=> f(-5/2) = 6(-5/2)⁴ + 5(-5/2)³ - 33(-5/2)² - 12(-5/2) + 20

=> f(-5/2) = 6(625/16)-5(125/8)-33(25/4)+30+20

when we simplify this one then we get,

=> f(-5/2)=(1,875-625-1,650+400)/8

=>  f(-5/2)=0/8

Here we know that if we zero by any number we get the result as zero.
