Step-by-step explanation:

Cost - 500

Marked Up - 250

Margin - 71.4286

MxCxMA= $1,750

This may seem confusing, but its $1,750 for the new price, and the equation is:

M= Marked

C= Cost

MA= Margin

The new price of the television is $1750.

To determine the quantity or percentage of something in terms of 100, use the percentage formula. Per cent simply means one in a hundred. Using the percentage formula, a number between 0 and 1 can be expressed. A number that is expressed as a fraction of 100 is what it is. It is mostly used to compare and determine ratios and is represented by the symbol %.

Given:

A television that costs $500 is marked up 250%.

So, the new price is

= 500 + 250% of 500

= 500 + 250/100 x 500

= 500 + 1250

= $1750

Hence, the new price of the television is $1750.

Answer:

pen = $1.20,  pencil = $0.50

Step-by-step explanation:

let x = pen

let y = pencil

create system of equations:

3x + 6y = 6.60        [can be simplified to be x + 2y = 2.20]

5x + 8y = 10.00

substitution method:

x = 2.2 - 2y

5(2.2 - 2y) + 8y = 10

11 - 10y + 8y = 10

-2y = -1

y = 1/2

solve for 'x':

3x + 6(1/2) = 6.6

3x + 3 = 6.6

3x = 3.6

x = 1.2

∠TAR =  35°

Step-by-step explanation:

∠TAR = ∠CAR - ∠CAT = (9x + 7) - 5x = 4x + 7

AT bisect ∠CAR       ∠TAR = ∠CAT

4x + 7 = 5x

x = 7

follow a few exponent rules and you can figure this out

when expoenents are to the power of something you can mutilply the expoents.. and when there is a minus sign in the exponent.. it's like the reciprocal   [tex]x^{-2}[/tex]  is  1/[tex]x^{2}[/tex]    soooo...

mutilply the  -2/3 by each of the exponents in the question the 8 is tricky b/c it has an invisible 1 on it :o

= [tex]8^{-2/3}[/tex][tex]w^{-14/3}[/tex][tex]x^{10/3}[/tex][tex]y^{-6/3}[/tex][tex]z^{18/3}[/tex]

= 1/[tex]\sqrt[3]{8*8}[/tex] * 1/[tex]w^{14/3}[/tex] * [tex]x^{10/3}[/tex] * 1/[tex]y^{2}[/tex] * [tex]z^{6}[/tex]

Answer:

[tex]\dfrac{48}{4}=12[/tex]

Step-by-step explanation:

Given that:

Dylan plays basketball.

In the season, he scored 48 points in total in the first four games of the season.

To find:

The equation to represent the average number of points scored per game.

Solution:

Average is the term used to find one number which can be used to represent a list.

It is usually the mid value.

Average can be found by using the following formula:

[tex]\text{Average =} \dfrac{\text{Sum of all the observations}}{\text{Number of observations}}[/tex]

Here, Sum of all the observations is the total score which is given as 48.

Number of observation is nothing but the number of games which is given as 4.

Therefore, the equation to find the average can be written as:

[tex]Average = \dfrac{48}{4}\\ \Rightarrow \bold{Average = 12}[/tex]

Answer:

9.74c-5.48p-64.8

Step-by-step explanation:

(9.74c-250.50)+(-5.48p+185.70)

9.74c-250.50-5.48p+185.70

Combine like terms

-250.50+185.70= -64.8

-64.8+9.74c-5.48p

Reorder them (variables first <alphabetically> then, a number)

Answer:

[tex]r=\frac{1}{4}\\\\r=-\frac{5}{4}[/tex]

Step-by-step explanation:

Geometric Sequences

The geometric sequence is given as:

[tex]a_1, a_1r, a_1r^2, a_1r^3,..., a_1r^{n-1}[/tex]

Where n is the number of the term, n≥1, and r is the common ratio.

The sum of n terms of the geometric sequence is given by:

[tex]\displaystyle S_n=a_1\frac{r^n-1}{r-1}[/tex]

We are given: S3=252, a1=192, thus substuting:

[tex]\displaystyle 252=192\frac{r^3-1}{r-1}[/tex]

Dividing by 12:

[tex]\displaystyle 21=16\frac{r^3-1}{r-1}[/tex]

Recall that:

[tex]r^3-1=(r-1)(r^2+r+1)[/tex]

Substituting:

[tex]\displaystyle 21=16\frac{(r-1)(r^2+r+1)}{r-1}[/tex]

Simplifying:

[tex]21=16(r^2+r+1)=16r^2+16r+16[/tex]

Rearranging:

[tex]16r^2+16r+16-21=0[/tex]

16r^2+16r-5=0

Rewriting:

[tex]16r^2-4r+20r-5=0[/tex]

Factoring:

[tex]4r(4r-1)+5(4r-1)=0[/tex]

[tex](4r-1)(4r+5)=0[/tex]

Solving:

[tex]r=\frac{1}{4}\\\\r=-\frac{5}{4}[/tex]

Both solutions are valid
