Step-by-step explanation:

Given parameters:

    Temperature at 8pm = 6°C

    Temperature at 2am = decreased by 13°C

Unknown:

Temperature at 2am

Solution:

Since this is a temperature decrease problem, the temperature at 2am should be lesser.

 Temperature at 2am = Temperature at 8pm - Temperature decrease

                                    = 6°C - 13°C

                                     = -7°C

Answer:

820 in profit

Step-by-step explanation:

The artist makes $82 in profit on each painting. 82 x 10 is 820

Given:

For gym A, initiation fee = $12 and cost = $10 per month.

For gym B, initiation fee = $20 and cost = $6 per month.

To find:

The equation that aims to find when these two gyms will cost the same amount of money,

Solution:

Let the number of months be x.

Cost function = Initiation fee + (cost)(x)

Cost function for gym A is

[tex]f(x)=12+10x[/tex]

Cost function for gym B is

[tex]g(x)=20+6x[/tex]

Cost of these two gyms are equal if f(x)=g(x).

[tex]12+10x=20+6x[/tex]

Therefore, the required equation is [tex]12+10x=20+6x[/tex].

On solving this equation, we get

[tex]10x-6x=20-12[/tex]

[tex]4x=8[/tex]

[tex]x=2[/tex]

Hence, after 2 months the cost of these two gyms are same.

Answer:

y = 1500 + 800x

Step-by-step explanation:

This is the answer because Elisa charges 1500 dollars no matter what. That value is not dependant on anything. Every hour she is with the client is 800 dollars. That is why it is represented as 800x. X being the amount of hours. You add the two together to find how much Elisa's services cost.

Answer: 2.456  x 10 to the power 11

Step-by-step explanation: Move the decimal so there is one non-zero digit to the left of the decimal point. The number of decimal places you move will be the exponent on the  10 . If the decimal is being moved to the right, the exponent will be negative. If the decimal is being moved to the left, the exponent will be positive.

Answer:

20 + 16 = 36

Step-by-step explanation:

The conjecture: "The sum of two positive even integers is always an odd integer" can be easily be proven false with a counterexample.

Pick A=20 and B=16, both are positive even integers.

The sum of both A + B = 36 is an even integer. This is a counterexample because being even is the contrary of being odd.

Counterexample: 20 + 16 = 36

In fact, the conjecture is always false, since there cannot be found any pair of positive integers whose sum is odd.

Other possible counterexamples are:

10 + 8, 700 + 40, 12 + 14, etc.

Answer:

The closest to the maximum profit is  [tex]x = \$ 83682[/tex]

Step-by-step explanation:

From the question we are told that

  The  mean is  [tex]\mu = \$66,000[/tex]

   The standard deviation is  [tex]\sigma  = \$ 21000[/tex]

   The percentage of profit is  20%

Generally the closest to the maximum annual profit at a store where the executives conducted an audit is mathematically evaluated  as follows

     [tex]P(X >  x ) =  0.20[/tex]

=>  [tex]P(X >  x ) = P(\frac{X -x}{\sigma }  >  \frac{x -66000}{21000} ) =  0.20[/tex]

From the z-table  the z-score for  0.20  is  

    [tex]z-score = 0.842[/tex]

So

     [tex]\frac{x -66000}{21000} = 0.842[/tex]

=>   [tex]x = \$ 83682[/tex]

Answer:

Step-by-step explanation:

Answer:

185 miles.

Step-by-step explanation:

According to the given situation, the calculation of mile is shown below:-

Assume drive = x miles

Total bill incurred = ($27 + 0.1 x) = $45.5

Now we will solve the above equation:

0.10x = $45.5 - $27

0.10x= 18.5

x = 18.5 ÷ 0.10

x = 185 miles.

So, the correct answer is 185 miles.

Answer:

{2, -3, -3/2}

Step-by-step explanation:

hi! we can set each of the binomials equal to 0 to find the zeros of this polynomial.

x-2=0

x=2

x+3=0

x=-3

2x+3=0

2x=-3

x=-3/2

The set includes all of the zeros for the polynomial would be; {2, -3, -3/2}.

They are mathematical expressions involving variables raised with nonnegative integers and coefficients(constants that are in multiplication with those variables) and constants with only operations of addition, subtraction, multiplication, and nonnegative exponentiation of variables involved.

We have been given the function f(x)=(x-2)(x+3)(2x+3)

Each of the binomials is equal to 0 to determine the zeros of this polynomial.

1. x-2=0

x=2

2. x+3=0

x=-3

3. 2x+3=0

2x=-3

x=-3/2

Hence, the set includes all of the zeros for the polynomial would be; {2, -3, -3/2}.

Step-by-step explanation:

Got Correct On MyPath.

The order of rotational symmetry for a rhombus is 2.

A polygon is a two-dimensional geometric figure that has a finite number of sides. The sides of a polygon are made of straight line segments connected to each other end to end

A rhombus is a special case of a parallelogram, and it is a four-sided quadrilateral.

In a rhombus, opposite sides are parallel and the opposite angles are equal.

All the sides of a rhombus are equal in length, and the diagonals bisect each other at right angles

Rotational Symmetry of a Rhombus has four equal sides but of varying angles.

A rhombus has two lines of symmetry (vertical and horizontal), an order of two, and the angle of rotation of 180 degrees

Hence,  the order of rotational symmetry for a rhombus is 2.
