round off 8.20155 to the nearest whole number ​

Answer: 4.2+(−1.2)+(−2.3) = 0.7

Answer:

5---6

Step-by-step explanation:

Given, the package of invitations contain [tex]12[/tex] invitations and package of envelopes contain [tex]10[/tex] envelopes.

Let [tex]x[/tex] and [tex]y[/tex] denote the number of invitation packages bought by Ronnie respectively.

It is given that, Ronnie bought the fewest number of invitations and envelopes so that there is exactly one envelope per invitation with none left over.

That is,[tex]12x-10y=0[/tex].

When, [tex]x=1[/tex] the value of [tex]y[/tex] becomes [tex]1.2[/tex].

It is not possible, since the number package cannot be in decimals.

When, [tex]x=2[/tex] the value of [tex]y[/tex] becomes [tex]2.4[/tex].

This is not possible, since the number package cannot be in decimals.

When, [tex]x=3[/tex] the value of [tex]y[/tex] becomes [tex]3.6[/tex].

This is not possible, since the number package cannot be in decimals.

When, [tex]x=4[/tex] the value of [tex]y[/tex] becomes [tex]4.8[/tex].

This is not possible, since the number package cannot be in decimals.

When, [tex]x=5[/tex] the value of [tex]y[/tex] becomes [tex]6[/tex].

This is not possible, since the number package cannot be in decimals.

Thus, Ronnie bought [tex]5[/tex] packages invitations and [tex]6[/tex] packages envelopes so that there is exactly one envelope per invitation with none left over.

Answer:

46

Step-by-step explanation:

PR = PQ + QR

4x - 10 = x +  2x + 4   {Combine like terms}

4x - 10 = 3x + 4     {Add 10 to both sides}

4x        = 3x + 4 + 10

        4x = 3x + 14              {Subtract 3x from both sides}

4x - 3x  = 14

          x = 14

PR = 4x - 10    {Plugin x = 14}

     = 4*14 - 10

     =  56 - 10

     =  46

Answer:

x = 12.053

Answer:

Step-by-step explanation:

Its like doing a long division with base 10 numbers:

           1110    <----------- Quotient

101)1001010

        101

         1000

            101

               111

                101

                  100

So the answer is 1110 remainder 100.

We can confirm this by converting to decimal numbers

1001010 = 74 and 101 = 5.

74 / 5 = 14 remainder 4.

A general linear equation is given by:

[tex]y = a*x + b[/tex]

Where a is the slope and b is the y-intercept.

Here we will find that the linear equation that represents the situation is

[tex]y = 0.033*x + 1.269[/tex]

And we can expect that the median salary in 2048 is $2.853 million

If the line passes through the points (x₁, y₁) and (x₂, y₂) then the slope can be written as:

[tex]a = \frac{y_2 - y_1}{x_2 - x_1}[/tex]

Here we know that:

in 2007 (x = 7) the median player salary was y = $1.5 million

in 2013 (x = 13) the median player salary was y = $1.7 million.

Then we have two points that we can write as:

(7, 1.5)

(13, 1.7)

Note that the y-value is in millions.

Then the slope of the linear equation will be:

[tex]a = \frac{1.7 - 1.5}{13 - 7} = 0.033[/tex]

So the linear equation is something like:

[tex]y = 0.033*x + b[/tex]

To find the value of b, remember the point (7, 1.5), this means that when we have x = 7, we also have y = 1.5, then we can replace these in the above equation:

[tex]1.5 = 0.033*7 + b\\\\1.5 - 0.033*7 = b = 1.269[/tex]

Then the linear equation is:

[tex]y = 0.033*x + 1.269[/tex]

b) Now we want to predict the median salary in 2048. For 2048 the x-value is x = 48

So we just need to evaluate this in the linear equation:

[tex]y = 0.033*48 + 1.269 = 2.853[/tex]

Then the median salary in 2048 will be $2.853 million

Based on the fact that there are  4 points which are given below, we have to move the trapezoid to the points of B will be (x+1, y-3).

The points on the graph are:

A trapezoid is regarded as a  quadrilateral that has only one pair of opposite sides that are said to be parallel.

It is made up of a right angles (called right trapezoid), and it can also contain a congruent sides (isosceles). Note that in the above, the only way the trapezoid  can fit into the translation movement (Point B)is if it is moved to the points of (x+1, y-3) on the graph.

After translation, the coordinate of point B' is (-4, 1).

Use the concept of coordinate defined as:

A pair of numbers which describe the exact position of a point on a cartesian plane by using the horizontal and vertical lines is called the coordinates.

The given translation is:

(x+1, y-3)

The coordinate of B' is (-5, 4)

Answer:

1/3

Step-by-step explanation:

I guess it's asking for probability of prime number

so we have 3 card and only one of them is prime (5)

so the answer is 1/3

Answer:

i would say 1/5 because it is between 2 and 12

Step-by-step explanation:

There are many examples you could go with, but one is "If a shape is a square, then it is always a rectangle".

The converse has us flip the statement into "If a shape is a rectangle, then it is always a square" which is not true. Some rectangles aren't squares.

------------------------

Another example could be "If it is a dog, then it is an animal" which is always true. The flip of it is "If it's an animal, then its a dog" which is false because the animal could be a cat for instance.

Equation of hyperbola is  [tex]\frac{x^{2} }{4} -\frac{y^{2} }{77} =1[/tex].

Hyperbola is defined as an open curve having two branches which are mirror images to each other.

A plane curve generated by a point so moving that the difference of the distances from two fixed points is a constant : a curve formed by the intersection of a double right circular cone with a plane that cuts both halves of the cone.

Given

Foci: (-9, 0) and (9, 0)

Foci: (±9, 0)

Vertices: (-2,0) and (2,0)

Vertices: (±2, 0)

So, a = ±2, c = ±9

Now [tex]c^{2} =a^{2} +b^{2}[/tex]

[tex]b^{2} =c^{2} -a^{2}[/tex]

[tex]b^{2} =9^{2} -2^{2}[/tex]

[tex]b^{2} =81-4[/tex]

[tex]b^{2} =77[/tex]

Equation of hyperbola is

[tex]\frac{x^{2} }{a^{2} } -\frac{y^{2} }{b^{2} } =1[/tex]

⇒ [tex]\frac{x^{2} }{4} -\frac{y^{2} }{77} =1[/tex]

Hence, equation of hyperbola is  [tex]\frac{x^{2} }{4} -\frac{y^{2} }{77} =1[/tex].

Step-by-step explanation:

3x + 5x  + 8x = 32

taking x common,

(3 + 5 + 8)x = 32

16x = 32

x = 32 / 16

x = 2

Answer: See below

Explanation:

The ultimate method of solving algebra problems will be trying any operations to isolate x, which then gives the value of x.

Operations include combining like terms, dividing and multiplying terms, and etc.

I would be solving [3x + 5x + 8x = 32] as an example.

Solve:

Given

3x + 5x + 8x = 32

Combine like terms through addition

8x + 8x = 32

16x = 32

Divide 16 on both sides to isolate x

16x / 16 = 32 / 16
