A 16-ounce bottle of water from Store A costs $1.28. The cost in dollars, y, of a bottle of water from Store B is represented by the equation y=0.07x, where x is the number of ounces. What is the cost per ounce of water at each store? Which store's bottle of water costs less per ounce?

A) The second equation is 2x - 4y +20=0, this system has no solutions.

B) The second equation is  x-2y-11=0, this system has infinite number of solutions.

An equation is a mathematical formula that expresses the equality of two expressions by connecting them with the equals sign =. The term equation and its cognates in various languages may have subtle changes in meaning.

Solving an equation with variables includes determining which variables' values result in equality. The variables for which the equation must be solved are also known as unknowns, and the unknown values that satisfy the equality are known as equation solutions. There are two sorts of equations: identities and conditional equations. An identity holds true for all variable values.

Given equation is,

2x - 4y = 22

A) Let the second equation be

2x - 4y +20=0

∴a₁/a₂=1

b₁/b₂=1

c₁/c₂=-11/10

Therefore, a₁/a₂=b₁/b₂≠c₁/c₂

Hence, the system has no solution.

B) Let the second equation be,

x-2y-11-0

Therefore,  a₁/a₂=b₁/b₂=c₁/c₂=2/1

The amount owed by the debtor is $10865

The given parameters about the compound interest are

Principal Amount, P = $5300

Interest Rate, R = 8%

Time, t = 6 years

To calculate the amount owed, we make use of the following formula

A = P + CI

Where

Compound interest, CI = P(1 + R)^t - P

So, the equation becomes

A = P + P(1 + R)^t - P

Evaluate the like terms

A = P(1 + R)^t

In this question, the formula is given as

A = P(1 + r/n)^nt

Where

n = 12, i.e compounded monthly

Substitute the known values in the above equation

A = 5300 * (1 + 8%/12)^(6*12)

Express 8% as decimal

A = 5300 * (1 + 0.08/12)^(6*12)

Evaluate the sum

A = 5300 * (1.01)^(6*12)

Evaluate the exponent

A = 5300 * 2.05

Evaluate the product

A = 10865

Hence, the value of the amount after 6 years is $10865

Here, d-1 is the largest possible value of N.

Given info,

For an arbitrary Markov chain on a state space consisting of exactly d states, find (with proof) the largest possible positive integer n such that for some states i,j, we have p(n) ij > 0 but p(n) ij.

We will prove that N ≤ d - 1

In light of this, there are states I and j such that the path from I to j has at least N edges, which implies that the path from I to j has at least d edges.

However, since there are only d states, the distance between any two states can be no greater than d-1. N can't thus be bigger than d-1.

Now, d-1 is the largest possible N because if we take a look at a Markov chain, if I is between 1 and d, we can only move to state 2 and if I is already at state d, we can only move to state d-1. However, if I am already at state 1, we can only move to state 1 and if I am already at state 2, we can only move to state i+1.

This sample contains d-1 edges on the way from state 1 to d. N = d-1 hence holds in this situation.

Therefore, N can have a value as large as d-1.

Answer:   m∡Ɪ  = 41.8 °

___

Step-by-step explanation:

Use the following mnemonic for right triangles:
 SOH  CAH  TOA ;

in which:
sin   =  opposite/ hypotenuse ;

cos  =  adjacent/ hypotenuse ;

tan =  opposite/adjacent ;

___
We shall solve for the unknown " m∡Ɪ " ;
 that is:  "the measure of Angle Ɪ ".

From looking at the image attached:
 Let's take at  ∡Ɪ .

  We see that the opposite side = 6 ; and that the hypotenuse = 9 ;
So, from the mnemonic mentioned ^above.

We use the SOH component:
    sin Ɪ = opposite /adjacent ;

             = 6/9 ;

      which can be reduced:
             " 6/9 =  (6÷3)/(9÷3) = (2/3) ."

So:  sin Ɪ = (2/3) ;

To solve for  Ɪ ;  

  We use a calculator; to take the (arcsin) of Each Side of the equation:

     [(arcsin) sin Ɪ ]  = (arcsin) ( [tex]\frac{2}{3}[/tex] ) ;

 to get:  Ɪ = 41.810314895779 ;
      [Source used:  Web2.0 Online Scientific Calculator].

Now, we shall round this calculated decimal number to the nearest tenth;  that is;  to the nearest single decimal point that appears after the non-decimal value.
    We have: 41.81... ;

So:  41.8 ? Or: 41.9 ?  If the digit in the hundredth place [that is, the next occurring decimal] is "4 or lesser" [i.e. "0, 1, 2, 3, or 4"] ; then we round down.  

  If the digit in the hundredth place [that is, the next occurring decimal] is "5 or greater" [i.e. "5, 6, 7, 8, or 9"] ; then we round down.

   In our case, we have:  "41.81..." ;
 →  As such, we round down to "41.8" .

  The correct answer is  " m∡Ɪ  = 41.8 °

Step-by-step explanation:

Answer:

  470 cm³

Step-by-step explanation:

You want the volume of a prism with an L-shaped base.

The volume of a prism is given by ...

  V = Bh

where B is the area of the base, and h is the distance between bases.

The base is has an L-shape. Its area can be found by extending the horizontal line to divide the figure into two rectangles.

The top rectangle is 4cm × 5cm, so has an area of ...

  A = LW = (4 cm)(5 cm) = 20 cm²

The bottom rectangle is 9 cm × 3 cm, so has an area of ...

  A = LW = (9 cm)(3 cm) = 27 cm²

Then the total base area is ...

  B = (top rectangle area) + (bottom rectangle area)

  B = (20 cm²) +(27 cm²) = 47 cm²

Then the volume is ...

  V = Bh = (47 cm²)(10 cm) = 470 cm³

The volume of the prism is 470 cm³.

The range of possible values of X are X>12.5

In mathematics, the range of a function can refer to one of two closely related concepts:

1. The function's codomain

2. The function's image

In mathematics, a function is an expression, rule, or law that explains a relationship between one variable (the independent variable) and another variable (the dependent variable).

A function is a sort of rule that generates a single output for a single input. In mathematics, a function is an expression, rule, or law that explains a relationship between one variable and another variable.  A good example is Y=X². You will only get one output for y if you enter anything for x. We can say that y is a function of X because X represents the input value.

The equation of the line passes through (-2, -1) and parallel to y = -1/3x - 5 is y = - 1 / 3 x - 5 / 3

The equation of a line can be represented in slope intercept form as follows:

y = mx + b

where

The equation of the line passes through (-2, -1) and parallel to y = -1/3x - 5

Therefore, the slope of the line is - 1 / 3.

Parallel lines have the same slopes.

Therefore, let's find the y-intercept using (-2, -1)

y = - 1 / 3 x + b

-1  = - 1 / 3 (-2) + b

b = -1 - 2 / 3

b =  -3 - 2/ 3
