There were 43 children at the playground. Now there are 27 children at the playground. How many children left the playground? Ben says that 13 children left the playground. He thinks that 43 – 30 is easier to subtract than 43 – 27. He subtracts 43 – 30 and gets 13. Why is Ben's reasoning not correct?

Answers

Answer 1

Ben is incorrect because Ben did not answer the question according to the available information. The fact that subtracting 43 from 30 is easier for Ben does not mean it is the correct answer.

Solve for X.

Answers

Answer:

x = 11/5

Step-by-step explanation:

3-3x = -8x +14

5x = 11

x= 11/5

Use distributive property
3-3x = -8x + 14
Add 8x to both sides
3+ 5x = 14
Subtract 3 from both sides
5x = 11
X = 11/5

Annabelle is ordering a taxi from an online taxi service. The taxi charges $2 just for the pickup and then an additional $1.50 per mile driven. How much would a taxi ride cost if Annabelle is riding for 6 miles? How much would a taxi ride cost that is mm miles long?

Answers

Answer:

$11

Step-by-step explanation:

Step one:

given

Taxi charges =$2

Additional charges =$1.50 per mile driven

Step two:

Required

The cost of the ride for a 6miles long drive

let the number of miles be x

and the total charges be y

The cost function is expressed as

[tex]y=1.5x+2[/tex]------------1

hence for x=6

y=1.5(6)+2

y=9+2

y=11

Therefore the cost of a 6miles drive will be $11

C personalities are organized and controlled. They take their time completing tasks accurately, like to research things thoroughly, and are always prepared.  Because they put so much time and effort into everything they do, they hate to be criticized. They are perfectionists at heart and take even the smallest complaint personally.  This makes them extremely difficult to confront. The best way to approach it is to focus on parts of the problem largely out of the C personality’s control or aspects of the problem they might not have considered.  Make it clear that you appreciate all of their efforts and that you’re bringing something to their attention because it’s a variable that they need to have in the equation in the future. No matter what, don’t frame the conflict as a personal attack. If you do, the C personality will likely become resentful and go out of their way to avoid future interactions with you.%%%%%%%%%%%%%%%

Answers

Answer: angle PST = 129 degrees

==============================================

Explanation:

Because S and T are midpoints of segments PQ and QR, we know that ST is a midsegment of triangle PQR. Consequently, this means ST is parallel to PR.

From the same side interior angle theorem, the angles (11x-3) and (5x-9) are supplementary angles. This is only true because of the parallel lines.

So we can say the following:

(angle P) + (angle S) = 180

(5x-9) + (11x-3) = 180

(5x+11x) + (-9-3) = 180

16x - 12 = 180

16x = 180+12

16x = 192

x = 192/16

x = 12

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

Use this to find angle PST

angle PST = 11x-3

angle PST = 11*12-3

angle PST = 132-3

angle PST = 129 degrees

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

Optionally we can find angle QPR

angle QPR = 5x-9

angle QPR = 5*12-9

angle QPR = 60-9

angle QPR = 51 degrees

As a check, adding the two angles we found should get us 180

(angle PST)+(angle QPR) = 129+51 = 180

The answer checks out.

Answers

Answer:

x² - x - 2 = 0

Step-by-step explanation:

plotting the graph of x and y,we have that the root of the equation is -1 or 2

x = -1 or 2

the eqn therefore is;

x² - (sum of the root)x + (product of the root) =. 0

x² - (-1+2)x + (-1*2) = 0

x² - x - 2 = 0

Applying the Factor Theorem, it is found that the quadratic function is:

[tex]p(x) = x^2 - x - 2[/tex]

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

The Factor Theorem states that if a polynomial [tex]p(x)[/tex] has roots [tex]x_1, x_2, ..., x_n[/tex], it is described by the following equation:

[tex]p(x) = a(x - x_1)(x - x_2)...(x - x_n)[/tex]

In which a is the leading coefficient.

For this quadratic function, the roots are [tex]x_1 = -1, x_2 = 2[/tex], as [tex]y(-1) = y(2) = 0[/tex], thus:

[tex]p(x) = a(x - (-1))(x - 2)[/tex]

[tex]p(x) = a(x + 1)(x - 2)[/tex]

[tex]p(x) = a(x^2 - x - 2)[/tex]

When x = 0, p(x) = -2, and we use this to find a.

[tex]p(x) = a(x^2 - x - 2)[/tex]

[tex]-2 = a(0^2 - 0 - 2)[/tex]

[tex]2a = 2[/tex]

[tex]a = \frac{2}{2}[/tex]

[tex]a = 1[/tex]

Thus, the quadratic function is:

[tex]p(x) = x^2 - x - 2[/tex]
