I need an equation that equals 20 like pre algebra

In linear equation , The company which has the best buy is company C, they sell 1 lion for $2.77 (highest selling price among the three companies.

What in mathematics is a linear equation?

Company A = 16 lions for $45.60

Price per lion = $45.60 / 16

= $2.85

Company B = 18 lions for $50.76

Price per lion = $50.76 / 18 eagles

= $2.82

Company C = $34.44 for 12 lion

Price per lion = $34.44 / 12 lion

= $2.87

Answer:

========================

Let the weekly salary is x.

Since both options end up with same amount, it can be shown as:

The matching choice is C.

The correct option is option C.

T(x) = 2.9(1.05)⁴ˣ ⁺ ⁵

Given the number of cities in a region is represented by the function:

C(x) = 2.9(1.05)ˣ

The approximate number of people per city is represented by the function P(x) = (1.05)³ˣ⁺⁵

we are asked to determine T(x), the approximate population in the region = ?

combine C(x) and P(x)

therefore, T(x) = C(x)P(x)

T(x) = 2.9(1.05)ˣ(1.05)³ˣ⁺⁵

During multiplication, when bases are same then powers are added.

T(x) = 2.9(1.05)³ˣ⁺ˣ⁺⁵

T(x) = 2.9(1.05)⁴ˣ⁺⁵

Hence we get the approximate function of T(x) as T(x) = 2.9(1.05)⁴ˣ⁺⁵

Step-by-step explanation:

The sum of the numbers as a product of their GCF is 5 x ( 5 + 7 ).

Given,

25 + 35.

We need to find its GCF and another sum.

It is the greatest factor common to both 25 and 35.

Example: 8 and 24

- 4 x 2 = 8

- 4 x 6 = 24

4 is the GCF.

Find the GCF of 25 and 35.

5 x 5 = 25

5 x 7 = 35

5 is the GCF of 25 and 35.

Now,

25 + 35 = 60

5 x ( 5 + 7 ) = 5 x 12 = 60

The sum of the numbers as a product of their GCF is 5 x ( 5 + 7 )

Thus,

The sum of the numbers as a product of their GCF is 5 x ( 5 + 7 ).

What is the 10% of number in which the 14% is 160

Although "pct," "pct," and occasionally "pc" are also used as abbreviations, the percent symbol "%" is most usually used to denote it. A% is a number that has neither dimensions nor a defined unit of measurement.

being that,

14% × x = 160

14/100 × x = 160

x = 160 × 100/14

x = 1142.86

The current value is 1142.86.

10% of the total number must be located.

to say,

10% x 1142.86 = 10 / 100 x 1142.86

= 114.286

Consequently, 114.286 is the value of the 10% of the number.

The initial amount and rate of change given a table for a linear function are $65 and $86, respectively

The table of linear function represents the given parameter

On the table, we have the following points

(x, y) = (6, 476) and (10, 736)

The rate of change is calculated as

Rate = (y2 - y1)/(x2 - x1)

So, we have

Rate = (736 - 476)/(10 - 6)

Evaluate

Rate = 65

This means that the rate of change is $65

The initial amount is calculated as

y = m(x - x1) + y1

Where

m = 65

So, we have

y = 65(x - x1) + y1

Using one of the points, we have

y = 65(x - 6) + 476

Set x = 0

So, we have

y = 65(0 - 6) + 476

Evaluate

y = 86

Hence, the initial amount and rate of change given a table for a linear function are $65 and $86, respectively

The amount of money left with them is $12,800.

The first step is to determine the amount left after 1/4 of the budget is spent on food stalls.

Budget left : (1 - 1/4) x amount of budget

3/4 x 32,000 = 24,000

The second step is to determine how much of the budget is left after spending on games and activities :

(1 - 3/10) x 24,000

7/10 x 24,000 = 16,800

The equation of a line which is perpendicular to [y = (4x - 11)] and passes through the point (-2, 1) will be [(4y + x) = 2].

As per the question statement, a line is perpendicular to [y = (4x - 11)] and passes through the point (-2, 1).

We are required to determine the equation of the above mentioned line.

Now, we know that, the standard equation of a line goes as [y = (mx + c)] where, "m" is the slope of the line while "c" is the y-intercept.

Comparing [y = (4x - 11)] to the standard form, we can identify that (m = 4), i.e., slope of the given line is 4.

Since the products of the slopes of two perpendicular lines is (-1), and considering the slope of our required line to be "m₁", we can say that,

[tex]4*m_{1}=(-1)\\ or,m_{1}=\frac{-1}{4}[/tex]...[since our required line is perpendicular to [y = (4x - 11)]

                        and slope of [y = (4x - 11)] is 4]

That is, slope of our required line is [tex](\frac{-1}{4})[/tex].

Another concept we need to know about forming the equation of a line is that, the equation of a line can be written as  [tex][(y-y_{1})=m(x-x_{1})][/tex], if the line passes through the point (x₁, y₁).

Here, our concerned line passes through the point (-2, 1) and has a slope of [m =  [tex](\frac{-1}{4})[/tex]].

Therefore, equation of our concerned line can be written as

[tex](y-1)=(\frac{-1}{4})[x-(-2)]\\or,(y-1)=(\frac{-1}{4})(x+2)\\or,(y-1)=(\frac{-x}{4})+(\frac{-1}{4}*2)\\ or,(y-1)=(\frac{-x}{4})+(\frac{-1*2}{4})\\or,(y-1)=(\frac{-x}{4})+(\frac{-1}{2})\\or,y=(\frac{-x}{4})+1+(\frac{-1}{2})\\or,y=(\frac{-x}{4})+(1-\frac{1}{2})\\or, y=(\frac{-x}{4})+\frac{1}{2}\\or,4y=(-x)+2\\or,4y+x=2[/tex]

Answer-  A) 59,600 ; B) 4.12% per year.

Explanation

84,200 minus 24,600 is 59,600. This means the originally cost put into the account was 59,600.

Next we have to divide the amount of interest earn into the number of years that the amount was accumulated. 24,600 divided by 10 is 2460. This means that each year 2,460 were earned in interest. 59,600 divided into 2,460 is 0.0412751678. This rounds to .0412 If we move our decimal to a percentage this leaves us with 4.12% This means that annual interest on the investment is 4.12%

The 12th term in the sequence is -26.

Given,

B (n) = -4 – 2(n – 1)

We have to find the 12th term in the sequence:

To find the nth term in an arithmetic sequence:

An arithmetic sequence's nth term is determined by the formula a = a + (n - 1)d. The common difference, or d, is the difference between any two consecutive terms in an arithmetic series; it can be calculated by deducting any pair of terms starting with a and an+1.

Here,

First term, a = -4

Common difference, d = -2

nth term = 12

Now, let’s find 12th term

B(n) = -4 -2(n – 1)

B(12) = -4 – 2(12 – 1)

B(12) = -4 -2(11)

B(12) = -4 -22

B(12) = -26

That is, the 12th term in the sequence is -26.

The amount of money that Gary can withdraw each month is equal to $4026.18.

Given the following data:

APR is an acronym for annual percentage rate and it can be defined as a measure of an amount of money based on a yearly rate of interest, which a borrower must pay on a loan or credit card.

This ultimately implies that, the annual percentage rate (APR) would be calculated by dividing the rate of interest by twelve (12).

Rate of interest, r = APR/12

Rate of interest, r = 0.05/12

Rate of interest, r = 0.0041667

Next, we would calculate the present value of this ordinary annuity by using this formula:

Present value, PV = [P ÷ [1 - (1 + r)^{-nt}]/r]

Substituting the given parameters into the formula, we have;

Present value = [750,000 ÷ [(1 - (1 + 0.0041667)^{-30 × 12})/0.0041667]

Present value = [750,000 ÷ [(1 - (1.0041667)^{-360})/0.0041667]

Present value = [750,000 ÷ [(1 - 0.2238239)/0.0041667]

Present value = [750,000 ÷ [0.7761761/0.0041667]

Present value = 750,000 ÷ 186.280773754
