Answer:

The polygon is a triangle, and is not a regular polygon.

Step-by-step explanation:

The polygon is a triangle because of it's three sides. It's also a non regular polygon since it's no equilateral or equiangular.

Step-by-step explanation:

Let x and y denote the cost of one hot dog and the cost of one hamburger.

ATQ,

Five hot dog(s) and four hamburger(s) cost $16.75 and four hot dog(s) and five hamburger(s) cost $17.00

So,

5x+4y = 16.75 ....(1)

4x + 5y = 17 ....(2)

Multiply equation (1) by 4 and equation (2) by 5.

20x+16y = 67 ....(3)

20x+25y= 85 ....(4)

Subtract equation (3) and (4).

20x+16y-(20x+25y) = 67-85

16y-25y = -18

-9y = -18

y = 2

Put the value of y in equation (2).

4x + 10 = 17

4x = 7

x = 1.75

So, the cost of one hot dog is $1.75 and that of cost of one hamburger is $2.

Answer:

The surface area of the composite figure is 1108 square inches.

Step-by-step explanation:

The surface area of the composite figure ([tex]A_{T}[/tex]) is equal to the sum of external faces of the rectangular and triangular prisms, all measured in square inches:

[tex]A_{T} = 20\,in \times 12\,in + 2\times 5\,in \times 12\,in + 2\times 20\,in \times 5\,in + 2\times 20\,in \times 11\,in + 2\times \frac{1}{2}\times 12\,in \times 9\,in[/tex]

[tex]A_{T} = 1108\,in^{2}[/tex]

The surface area of the composite figure is 1108 square inches.

Step-by-step explanation:

7x + 1 isn't equal to 8x

For example:

Addition. In this equation, you can add all of the coefficients (2, 5, and 4) because the variables are the same (a).

2a + 5a + 4a = 11a

Subtraction. In this equation, you can subtract all of the coefficients (11, 5, and 4) because the variables are the same (a).

11a – 5a – 4a = 2a

Answer:

A

Step-by-step explanation:

[tex] \frac{4x - 3}{7} [/tex]

Replace y with x.

[tex]x = \frac{4y - 3}{7} [/tex]

Solve for y.

[tex]7x = 4y - 3[/tex]

[tex]{7x + 3}{} =4 y[/tex]

[tex] \frac{7x + 3}{4} = y[/tex]

Answer:

  1.  monthly: 0.25%; quarterly: 0.75%

  2.  monthly: ≈ 0.45833%; quarterly: 1.375%

Step-by-step explanation:

In each case, the base of the exponential term is the annual growth factor. The annual growth rate (interest rate) is ...

  growth rate = growth factor - 1

Then the monthly rate is ...

  monthly rate = growth rate/12

and the quarterly rate is ...

  quarterly rate = growth rate/4

__

1. monthly rate = (1.03 -1)/12 = 0.03/12 = 0.0025 = 0.25%

  quarterly rate = (1.03 -1)/4 = 0.03/4 = 0.0075 = 0.75%

__

2. monthly rate = (1.055 -1)/12 = 0.055/12 ≈ 0.0045833 = 0.45833%

  quarterly rate = (1.055 -1)/4 = 0.055/4 = 0.01375 = 1.375%

Answer:

[tex]x^3+8x^2+2x+1[/tex]

Step-by-step explanation:

Combine like terms (terms with the same exponent).

[tex]x^3+(3x^2+5x^2)+(x+x)+1=x^3+8x^2+2x+1[/tex]

"Standard form" means to list terms so the exponents go from high to low (descending order).

A) The dimensions are (x+10) by (x+10).

B) The perimeter is given by 4x+40.

C) The perimeter when x is 4 is 56.

The quadratic can be factored by finding factors of c, the constant, that sum to b, the coefficient of x.  Our c is 100 and our b is 20; we want factors of 100 that sum to 20.  10*10=100 and 10+10=20, so those are what we need.  This gives us (x+10)(x+10 for the factored form.  

Since the dimensions are all (x+10), and there are 4 sides, the perimeter is given by 4(x+10).  Using the distributive property we have 4*x+4*10=4x+40.

To find the perimeter when x=4, substitute 4 into our perimeter expression:

4*4+40=16+40=56.

Answer:

A) The dimensions are (x+10) by (x+10).

B) The perimeter is given by 4x+40.

C) The perimeter when x is 4 is 56.

Answer:

b) 9.99 + 1.29n ≤ 50

Step-by-step explanation:

  I think,  this question is incomplete., may be there is typo. To complete the question, it's suppose to be like this  

a)9.99 + 1.29n ≥ 50

b)9.99 + 1.29n ≤ 50

c)9.99 − 1.29n  ≤ 50

d)9.99 − 1.29 n ≥ 50

well,  we have to figure out  the information given  

price of the album: $9.99

each song cost : $1.29

gift card: $50

number of songs : n

The answer  is b) 9.99 + 1.29n  ≤ 50 , because the sum of the price of the album ($9.99) and the songs ($1.29 n) must be less or equal to the value of the gift card ($50). Fore sure it 's correct.....

Answer:

The data is a random sample from the population of interest and The sample size is less than 10% of the population size. ( b )

Step-by-step explanation:

roasted beef protein = 20 grams  ( mean value )

sample size of soybean compound = 5

mean value of their protein = ( 15 + 22 + 17 + 18 + 23)  / 5 = 19

The conditions that have been met are :

The data is a random sample from the population of interest. and

we can say the sample size is less than 10% of population size because we do  know the population size is a large supply

Answer:

Step-by-step explanation:

20 × 400 = 8000

8000 - 7200 = 800

therefore the % mark up is 10%, because 10% of 8000 is 800.

800 + 7200 = 8000

Answer:

Octopus Location: 0

Step-by-step explanation:

If the octopus was swimming 3 ft below the surface, it's considered -3.

The octopus then swam up 3 feet, so we add 3 to the -3 from the previous statement.

-3 + 3 = 0

Answer:

V= 8

x=4.5

BCF =48 CFE=132

V=352.8 =8.4x8.4x5

For the volume one i cant read the number but if the bottom number is 8 then V=803.84

if its 6 then v = 452.16

Step-by-step explanation:

v= 2x2x2 v = 8

x is 11x-9=7x+9 | 4x=18 | x=4.5

15x=180 x=12 | CFE = 11x12=132 | BCF = 4x12=48

Answer:

[tex] \frac{Sin(80)}{RS} = \frac{Sin(52.5)}{7} [/tex]

Step-by-step explanation:

Given:

S = 52.5°

s = QR = 7

Q = 80°

q = RS = ?

Required:

Equation that could be used to find the length of RS

Solution:

We would need the law of Sines which is given as:

[tex] \frac{Sin(A)}{a} = \frac{Sin(B)}{b} = \frac{Sin(C)}{c} [/tex]

Applying the Law of Sines, we would have the following equation:

[tex] \frac{Sin(Q)}{q} = \frac{Sin(S)}{s} [/tex]

Plug in the values

[tex] \frac{Sin(80)}{RS} = \frac{Sin(52.5)}{7} [/tex]

Therefore, the equation that can be used to determine the length of RS is [tex] \frac{Sin(80)}{RS} = \frac{Sin(52.5)}{7} [/tex]

Answer:

  sin(θ) = -12/13

Step-by-step explanation:

The distance from the origin to the given point is ...

  r = √(5² +(-12)²) = √169 = 13

For point (x, y) ⇔ (r; θ), recognize that (x, y) = (r·cos(θ), r·sin(θ)). This translates to ...

  sin(θ) = y/r

  sin(θ) = -12/13
