Two angles of a quadrilateral measure 260° and 15º. The other two angles are in a ratio of 7:10. What are the measures of those two angles?

Answer:

statement 1 is true

statement 2 is true

statement 3 is false

statement 4 is false

statement 5 is also false cause parallelogram has 2 pair of congruent sides

Answer:

n = 8

Step-by-step explanation:

to solve this equation you must first isolate the variable

that is n

so first

add 2n to both sides to get rid of n on one of the sides

-4n + 2n + 14 = -2 - 2n + 2n

-2n + 14 = -2

now subtract 14 to both sides to isolate n

-2n + 14 - 14 = -2 - 14

-2n = -16

now divide everything by -2 to isolate n completely

(-2n)/(-2) = (-16)/(-2)

n = 8

that is your answer

Answer:

[tex]\boxed{\sf n=8}[/tex]

Step-by-step explanation:

[tex]\sf -4n+14=-2-2n[/tex]

Subtract 14 from both sides:-

[tex]\sf -4n+14-14=-2-2n-14[/tex]

Simplify:-

[tex]\sf -4n=-2n-16[/tex]

Add 2n to both sides:-

[tex]\sf -4n+2n=-2n-16+2n[/tex]

Simplify:-

[tex]\sf -2n=-16[/tex]

Divide both sides by -2:-

[tex]\sf \cfrac{-2n}{-2}=\cfrac{-16}{-2}[/tex]

Simplify:-

[tex]\sf n=8[/tex]

Annual nominal rate compounded monthly has the account earned is 0.84% .

In the question ,

it is given that ,

An employee opened a credit union account ,

amount deposited each month (PMT) = $90

number of period (n) = 2 years = 24 months

Future value after 2 years (FV) = $2177.48

let the rate of interest  compounded monthly has the account earned be "r"

we know that the future value formula is

Future Value = PMT× [tex](\frac{(1+\frac{r}{12})^{n} -1 }{\frac{r}{12} } )[/tex]

Substituting the value of n = 24 , PMT = 90 and FV = 2177.48 in the Future Value Formula ,

we get ,

2177.48 = 90 × [tex](\frac{(1+\frac{r}{12})^{24} -1 }{\frac{r}{12} } )[/tex]

[tex](\frac{(1+\frac{r}{12})^{24} -1 }{\frac{r}{12} } )[/tex] = 2177.48/90

( 1 + r/12 )²⁴ -1 = (r/12) × 24.194

A rectangular container with a square base, an open top, and a volume of 4,000 cm³. The minimum surface for the container is 1,200 cm².

The result is obtained by using the derivative.

These are the specified parameters:

Volume container is 4,000 cm³.

Let side of square base = a, and height of the container = h, so:

Volume = a × a × h

4,000 = a² h

       h = [tex]\displaystyle \frac{4000}{a^2}[/tex]     ... (1)

Surface area with a square base, an open top is area of a square + 4 times the vertical side.

Surface area (A) = a² + 4ah

Substitute the value of h = [tex]\displaystyle \frac{4000}{a^2}[/tex] into surface area.

A = a² + 4ah

A = a² + 4a ([tex]\displaystyle \frac{4000}{a^2}[/tex])

A = a² + [tex]\displaystyle \frac{16000}{a}[/tex]

So that the surface area is minimal, when the derivative and equate to 0.

A = a² + 16000 a⁻¹

A' = 0

2 a²⁻¹ + (-1) 16000 a⁻¹⁻¹

2a - 16000 a⁻²  = 0

2a - [tex]\displaystyle \frac{16000}{a^2}[/tex] = 0

2a = [tex]\displaystyle \frac{16000}{a^2}[/tex]

2a³ = 16000

 a³ = [tex]\displaystyle \frac{16000}{2}[/tex]

 a³ = 8000

 a = ∛8000

 a = 20

Surface area with a square base, an open top.

Substitute the value of a = 20

A = a² + [tex]\displaystyle \frac{16000}{a}[/tex]

A = 20² + [tex]\displaystyle \frac{16000}{20}[/tex]

A = 400 + 800

A = 1200

The minimum surface for the container is 1,200 cm².

Answer:

The amount of cholesterol in 11 ounces of lobster is 220 mg

Step-by-step explanation:

The amount of cholesterol in 11 ounces of lobster can be calculated as follows

The first step is to convert all units of measure from ounce to mg

1 gram = 0.0352 ounce

Divide both sides by 0.0352 to get the value of 1 ounce

[tex]\frac{1}{0.0352}[/tex] gram = [tex]\frac{0.0352}{0.0352}[/tex] ounce

28.35 gram = 1 ounce

Since 1 gram equals 1000 milligrams, then multiply the left side by 1000 and change the unit of measure to milligram

28.35 [tex]\times[/tex] 1000 mg = 1 ounce

28350 mg = 1 ounce

Convert 3.6 ounces to milligrams

3.6 ounces = 3.6 [tex]\times[/tex] 28350 mg

3.6 ounces = 102060 mg

Convert 11 ounces to milligrams

11 ounces = 11 [tex]\times[/tex] 28350 mg

11 ounces = 311850 mg

Since there are 72 mg of cholesterol in a 3.6 ounces serving of lobster, then the ratio equation to follow is

[tex]\frac{72}{102060}=\frac{x}{311850}[/tex]

Where x is the amount of cholesterol in 11 ounces of lobster

Multiply both sides by 311850 to isolate x

[tex]\frac{72}{102060}\times 311850=\frac{x}{311850}\times 311850[/tex]

[tex]\frac{22453200}{102060} =x[/tex]

Simplify the left side of the equation

220 = x

Since the value of x is 220, then the amount of cholesterol in  11 ounces of lobster is 220 mg

The new coordinate after the given composite translation (x,y) → (x-5,y+5) will be (x+3,y+12).

Transformation is rearranging a graph by a given rule it could be either increment of coordinate or decrement or reflection.

Reflection is a mirror image of a graph about any axis.

If we reflect any graph about y = x then the coordinate will interchange it that (x,y) → (y,x).

As per the given translation rule,

(x,y) → (x+8,y+7)

The next translation is (x,y) → (x-5,y+5)

The resultant translation will be,

(x,y) → (x+8,y+7) to (x+8-5,y+7+5)

⇒ (x+3,y+12)

Hence "The new coordinate after the given composite translation (x,y) → (x-5,y+5) will be (x+3,y+12)".

If there are four consecutive odd integers such that five times the second number minus twice the fourth number is the third number subtracted by 252 then the four consecutive integers are -2, -3, -4, -5 (or) -2, -1, 0, 1.

What are consecutive integers?

Whole numbers that follow each other without gaps are known as consecutive integers.

For example, the numbers 15, 16, and 17 are all consecutive integers.

If 'n' is an integer, then the following consecutive integers begin at n, n+1, n+2, n+3, and so on.

Let x be the 1st of the four consecutive integers.

the other three consecutive integers could be

(x + 1) , (x + 2), and (x + 3).

By using the given conditions, we get

From the question,

(x + 1) = (5 * (x + 2)) - (x + 3)

Expand, and subtract like terms:

x + 1 = 5x + 10 - x - 3.

Simplifying the above expression, we get

x + 1 = 4x + 7.

3x = -6.

x = -2.

For the given rectangular playpen, the perimeter of rectangular playpen is 150 feet and its area is at least 1000 square feet. then the length of the rectangular playpen is equal to at least 17.35 feet and at most 57.66 feet.

As given in the question,

For the given rectangular playpen,

Perimeter of rectangular playpen is equal to 150 feet .

Area of the rectangular playpen is equal to at least 1,000 squared feet .

Area = length × width

Let x be the length of the rectangular playpen .

Then its width is equal to 1000 / x.

Substitute the value of length and width in perimeter we get,

Perimeter of rectangular playpen = 2 ( length + width )

⇒ 150 = 2 [ x + (1,000/x)]

⇒ 150 / 2 = ( x² + 1,000 ) / x

⇒ x² + 1000 = 75x

⇒ x² -75x + 1,000 =0

Simplify quadratic equation using discriminant we get,

x = [ -( -75) ± √(-75)² - 4(1) (1,000) ] / 2(1)

⇒ x = (  75 ± √5625 - 4000) /2

⇒ x = (75 ± 40.31) / 2

⇒ x = 57.66 or 17.35

Therefore, for the given rectangular playpen, the perimeter of rectangular playpen is 150 feet and its area is at least 1000 square feet. then the length of the rectangular playpen is equal to at least 17.35 feet and at most 57.66 feet.
