the measure of one interior angle of a regular 90-sided polygon.

Answer:

V = 125.6 in³

Step-by-step explanation:

let V be volume, h the height and r the radius, then the equation relating the quantities is

V = khr² ← k is the constant of variation

To find k use the condition V = 402.12, h = 8, r = 4

402.12 = k × 8 × 4² = 128k ( divide both sides by 128 )

3.14 = k [ note 3.14 is π )

V = 3.14hr² ← equation of variation [ V = πr²h ]

Given r = 2 and h = 10, then

V = 3.14 × 10 × 2² = 3.14 × 40 = 125.6

Answer:

n < -10

Step-by-step explanation:

n+7 < -3

subtract 7 from both sides

n+7-7 < -3-7

n < -10

Answer:

The solution set is (5,6).

Step-by-step explanation:

Given equations are:

-6x + 6y= 6         Eqn 1

-6x + 3y=-12      Eqn 2

Subtracting Eqn 2 from Eqn 1

(-6x+6y)-(-6x+3y)= 6-(-12)

-6x+6y+6x-3y=6+12

3y = 18

Dividing both sides by 3

[tex]\frac{3y}{3}=\frac{18}{3}\\y=6[/tex]

Putting y=6 in Eqn 1

-6x+6(6)=6

-6x+36=6

-6x=6-36

-6x=-30

[tex]\frac{-6x}{-6}=\frac{-30}{-6}\\x=5[/tex]

Hence,

The solution set is (5,6).

Answer:

the wrong answer is C, but the right answer is A

Answer:

The time required to  accumulate simple interest of $ 60.00

from a principal of $ 750.00  at an interest rate of 4% per year  is 2 years.

Step-by-step explanation:

Given

To determine

Time period t = ?

Using the formula

I = Prt

t = I / Pr

substitute I = $60, P = $750 and r = 0.04 in the equation

t = 60 / ( 750 × 0.04 )

t = 2  years

Therefore, the time required to  accumulate simple interest of $ 60.00

from a principal of $ 750.00  at an interest rate of 4% per year  is 2 years.

Answer:

15%

Step-by-step explanation:

First, let's find how many pounds the dog's weight increased by during the year.

80 - 64 = 16

Now, knowing that the dog's weight increased by 16 pounds, we can use that to figure out the percentage of 16 out of 64 (divide them, then multiply by 100 to get a percentage).

[tex]\frac{16}{64}[/tex] • 100 = 0.25 • 100 = 25%

Given that,

Total cost function, C (x) = 43x + $1850

The revenue function R (x) = $80x

To find,

The number of units that must be produced and sold to break even.

Solution,

At break even, cost = revenue

43x + $1850 = $80x

Subtract 80x from both sides.

43x + 1850 -80x = $80x -80x

1850 = 80x-43x

37x = 1850

x = 50

So, the required number of units are 50.

4.3x+5x=16+7-(7)

9.3x=16

x= 1.72

give me a brainliest if possible. please.. tnx

Answer:  1.72.......

Step-by-step explanation:  4.3x + 7 + 5x = 16 + 7

=> 7 + (5x + 4.3x) = 16 + 7

7 + 9.3x = 23

9.3x = 23 - 7    [ 7 becomes -7 when transferred to RHS]

9.3x = 16

x = 16 /9.3    [ 9.3 becomes 1/9.3 when transferred to RHS]

x = 1.72......

Step-by-step explanation:

Answer:

$50

Step-by-step explanation:

Price of the cell phone bought p = $40

% of markup in price = 25%

Selling price of the cell phone = p + (%)p

Selling price of the cell phone = P + (0.25)p

Selling price of the cell phone = p + 0.25p

Selling price of the cell phone = 1.25p

Selling price of the cell phone = 1.25 * $40

Selling price of the cell phone = $50

Answer:

[tex] x = -2 [/tex]   or   [tex] x = -5 [/tex]

Step-by-step explanation:

You need to complete the square before you can take the square root of both sides.

[tex] x^2 + 7x + 10 = 0 [/tex]

Subtract 10 from both sides.

[tex] x^2 + 7x = -10 [/tex]

To complete the square, you need to add the square of half of the x-term coefficient to both sides.

The x-term coefficient is 7. Half of that is 7/2. Square it to get 49/4. Now we add 49/4 to both sides of the equation.

[tex] x^2 + 7x + \dfrac{49}{4} = -10 + \dfrac{49}{4} [/tex]

[tex] (x + \dfrac{7}{2})^2 = -\dfrac{40}{4} + \dfrac{49}{4} [/tex]

[tex] (x + \dfrac{7}{2})^2 = \dfrac{9}{4} [/tex]

Now we use the square root property, if

[tex] x^2 = k [/tex], then

[tex] x = \pm \sqrt{k} [/tex]

[tex] x + \dfrac{7}{2} = \pm \sqrt{\dfrac{9}{4}} [/tex]

[tex] x + \dfrac{7}{2} = \pm \dfrac{3}{2} [/tex]

[tex] x + \dfrac{7}{2} = \dfrac{3}{2} [/tex]   or   [tex] x + \dfrac{7}{2} = -\dfrac{3}{2} [/tex]

[tex] x = -\dfrac{4}{2} [/tex]   or   [tex] x = -\dfrac{10}{2} [/tex]

[tex] x = -2 [/tex]   or   [tex] x = -5 [/tex]

Answer:

[tex]x = - 3[/tex]

Step-by-step explanation:

[tex] - 2(3x - 2) + 2x = - 6x - 10[/tex]

[tex] = > - 6x - 4 + 2x = - 6x - 10[/tex]

[tex] = > - 4x - 4 = - 6x - 10[/tex]

[tex] = > - (4x + 4) = - (6x + 10)[/tex]

[tex] = > 4x + 4 = 6x + 10[/tex]

Keeping all like terms in L.H.S ,

[tex] = > 6x - 4x = 4 - 10[/tex]

[tex] = > 2x = - 6[/tex]

[tex] = > x = \frac{ - 6}{2} = - 3[/tex]

Step-by-step explanation:

m∠LON ≅ m∠M        Property of Parallelogram; Opposite angles are congruent

m∠M = 118°                Given

m∠LON = 118°            Substitution

m∠OLN + m∠LNO + m∠LON  = 180°      Sum of angles in a triangle

m∠OLN + 118° + 22° = 180°                      Substitution

m∠OLN = 40°                                            Algebra
