Using the equation S = (n − 2) 180, find the measure for one Interior angle of a decagon (10-sides). Round to one decimal place if necessary.

Answer:

$71

Step-by-step explanation:

Tim has M dollars

Rebecca is having (M/10 - 6)

Then, the amount of money Tim and Rebecca are having

= M + M/10 - 6

= (11M/10) - 6 dollars

The expression representing the total amount of money is [(11X/10) - 6]

If Tim is having $70, then total amount both would have together

= [(11 × 70/10) - 6]

= 77 - 6

= $71

Therefore, the expression for the total amount is [(11M/10) - 6] dollars

The total amount both are having together is $71.

Answer:

B. The expression is 11/10m – 6, and the amount is $71.

Step-by-step explanation:

Our point is (-5, -4)

Now use point slope form to find the equation: (y - y1) = m(x - x1)

(y - y1) = m(x - x1)

(y - (-4)) =-4/5(x - (-5))

y + 4 = -4/5x +4

An equation in slope-intercept form of the line is y = -4/5x - 8. The correct option is B.

An equation of the line is defined as a linear equation having a degree of one. The equation of the line contains two variables x and y. And the third parameter is the slope of the line which represents the elevation of the line.

The general form of the equation of the line:-

y = mx + c

m = slope

c = y-intercept

Slope = ( y₂ - y₁ ) / ( x₂ - x₁ )

Given that the slope −4/5 contains the point (−5,−4). The equation of the line is written as,

y = mx + c

-4 = -4/5 x - 5 + c

-4 = 4 + c

c = -8

The equation will be written as,

y = -4/5x - 8

Answer:

[tex]\displaystyle \int {\frac{1}{\sqrt{x} \sqrt{1-x} } } \, dx = 2arcsin(\sqrt{x}) + C[/tex]

General Formulas and Concepts:

Calculus

Step-by-step explanation:

Step 1: Define

[tex]\displaystyle \int\limits {\frac{1}{\sqrt{x} \sqrt{1-x} } } \, dx[/tex]

Step 2: Identify

Set up variables for u-substitution and integral trig.

[tex]\displaystyleu = \sqrt{x}\\a = 1\\du = \frac{1}{2\sqrt{x}}dx[/tex]

Step 3: integrate

We are given the expression:                                                                              

[tex]\int\limits {\frac{1}{\sqrt[]{x} }*\frac{1}{\sqrt[]{ 1-x^{2}}} } \, dx[/tex]

U-substitution:                                                                                                      

let u = [tex]x^{1/2}[/tex]             [So, x = u²]

[tex]\frac{du}{dx} = \frac{1}{2\sqrt[]{x}}[/tex]                 [differentiating both sides wrt x]

dx = du*2√(x)

dx = 2u(du)            [Since u = √x]

Finding the Integral:                                                                                              

Plugging these values in the given expression:

[tex]\int\limits {u^{-1}*(1-u^{2})^{-1/2} } \, 2\sqrt[]{x}*du[/tex]

[tex]\int\limits {\frac{1}{u}*\frac{1}{\sqrt[]{ 1-u^{2}}}*2u } \, du[/tex]

The 'u' in the numerator and denominator will cancel out

[tex]\int\limits {\frac{1}{\sqrt[]{ 1-u^{2}}}*2 } \, du[/tex]

Since 2 is a constant

[tex]2\int\limits {\frac{1}{\sqrt[]{ 1-u^{2}}} } \, du[/tex]

Using the property: [tex]\int\limits {\frac{1}{\sqrt[]{1-x^{2}} }} \, dx[/tex] = ArcSin(x) + C

2*ArcSin(u) + C

Since u = √x :

2*ArcSin(√x) + C

Answer: $6,120

Step-by-step explanation:

There are 15 fruits in each basket.

The store shipped 3,825 fruits, to find the number of baskets of fruits shipped you have to divide 3,825 by 15.

3,825 ÷ 15 = 255

Each basket costs $24 so to find the cost of 255 baskets, you multiply 255 by 24.

$24 × 255 = $6,120

Leona earned $6,120 from the gift baskets sold.

Answer:

28 pizzas can be bought

Step-by-step explanation:

you have to find the unit rate of the pizzas.

so 135 divided by 15 which is 9

and then you divide 252 by 9

It is found that 28 pizzas can be bought with 252 dollar.

There is an independent quantity, and a quantity that depends on it (dependent quantity). When independent quantity moves by a unit measurement (single unit increment), the increment in dependent quantity is called the rate of increment of dependent quantity per unit increment in independent quantity.

We have been given amount of money spent on a pizza for club activities varies directly with the number of pizzas bought.

We need to find the unit rate  of the pizzas

Unit rate = Total amount/ Number of pizzas

Unit rate = 35/15

Unit rate = 9

Also,Unit rate = 259/13

Unit rate = 28

Therefore, 28 pizzas can be bought.

Answer: c

Step-by-step explanation:

look at the equation and insert the value of X from the table into the equation and figure out which one will give you the same sum for the values. for example f(x) = 3(-2)-1

this answer gives you f(x)= -6 -1 which will give u a sum of -7

another one : f(x)= 3(0)-1

3 multiplied by 0 gives you 0 therefore you are left with -1

by doing this you prove that this equation works with ur x values and gives you the same sum you have for f(x)

Answer:

$115.2

Step-by-step explanation:

Step one:

Given data

A store used to sell an MP3 for $72 and we are told that this 50% of the wholesale price.

Therefore the wholesale price is

72*2= $144

Required:

The special sales cost at 20% discount

Step two:

We are told that the special sale is at a 20% discount on the wholesale

= 20/100*144

=0.2*144

=$28.8

Therefore the special sales price is

= 144-28.8

=$115.2

Answer:

10x + 60 ; 20x

Step-by-step explanation:

Given that:

Purchase price per bracelet = $10

Cost of booth = $60

Selling price per bracelet = $20

Hence,

Let number of bracelets = x

Expense equation :

(Price per bracelet * number of bracelet) + booth fee

(10 * x) + 60

10x + 60

Income equation :

Selling price * number of bracelets

Step-by-step explanation:

Here, we want to seek why the system has no solutions

An example is necessary

Let us have two lines with equal slopes and different y-intercepts

y = 2x + 5

y = 2x - 3

To solve this system, we equate the y-values

2x + 5 = 2x - 3

The reason why this has no solution is that there is no x value that would validate the equality

It is impossible to find an x value which when inserted would make both equations equal

In the absence of this, we can make that conclusion that the system of equations has no solution

I actual foot represents 0.01093 foot on paper

Step-by-step explanation:

Given that :

Actual side length of snack stand = 60 feets

Length of side on map = 20cm

Scaie :

60 feet = 20cm

1 foot = (20/60) cm

1 foot = 0.333 cm

1cm = 0.0328084 foot

0.333cm = (0.33 * 0.0328084) = 0.01093 feets

Scale :

I actual foot represents 0.01093 foot on paper

Answer:

y = 4x - 4

Step-by-step explanation:

to write a linear equation you need to know 2 components:  slope and y-intercept

find slope by selecting 2 points, for example, (1,0) and (2,4)

slope ('m') = difference of y-values              4 - 0  =  4

                    difference of x-values             2 - 1        1

to find y-intercept ('b'), plug values into the slope-intercept form of a line, which is:

y = mx + b

you need a point and the slope of 4/1; can use any point

we'll use (2,4) where x =2 and y=4  and, again, m = 4

4 = 2(4) + b

4 = 8 + b

-4 = b

Step-by-step explanation:

Answer:

The slope of the Green line should be the same as the red line- but a negative number instead of a positive.

Step-by-step explanation:

This is the inverse of the line

So by reflecting it over the y-axis, the slope remains the same but will change from positive to negative and vise versa
