A two digit number is such that, the sum of its digit is 13.When the digits are interchange, the original number is increased by 9. Find the original number.​

Answers

Answer:

Concept: Mathematical Representation

You have a two digit # __ The sum of the two digit # = 13The original # increased by 9 Hence we must find values that sum to 13. *Note they must be independently standing.8+5, 9+6, 7+6 , 6+7 , and etcThe value must also increase by 9 So logically it would be any result that when switched that value would be 76-67= 9.So the value must be 67

Answers

r = -1

Step-by-step explanation:

So first, we need to get this is order of: ax^2 + bx + c

3r^2 - 6 - 3r

3^2 - 3r - 6

the formula is: -b ± √b^2 -4ac/2a

"ax^2 + bx + c" = "3^2 - 3r - 6"

a = 3

b = -3

c = -6

-b ± √b^2 -4ac/2a

-(-3) ± √(-3)^2 -4(3)(-6)/2(3)

3 ± √9 + (-12)(-6)/6

3 ± √9 + (72)/6

3 ± √9 + 72/6

3 ± √81/6

A rectangle is 3 cm longer than it is wide. The diagonal is 15 cm. Find the dimensions of the rectangle?

Answers

Answer:

The length is 12 cm, and the width is 9 cm.

Step-by-step explanation:

The length and width of a rectangle as legs form a right triangle with the diagonal of the triangle as the hypotenuse.

We can use the Pythagorean theorem to write an equation.

Let the width = w = leg a

The length = w + 3 = leg b

The diagonal = the hypotenuse = 12 = c

a^2 + b^2 = c^2

w^2 + (w + 3)^2 = 15^2

w^2 + w^2 + 6w + 9 = 225

2w^2 + 6w - 216 = 0

w^2 + 3w - 108 = 0

(w + 12)(w - 9) = 0

w + 12 = 0   or   w - 9 = 0

w = -12   or   w = 9

Since a width cannot be a negative number, we discard the solution w = -12.

width = w = 9

length = w + 3 = 9 + 3 = 12

Answer: The length is 12 cm, and the width is 9 cm.

A photography studio charges $50 for a sitting fee and 6 prints. Luigi increased his order to 11 prints and paid $65. Write an equation in point-slope form.

HELP ME PLEASEEEE!!!

Answers

Answer: Sitting fee - 32$

Step-by-step explanation:

This is a system of equations(let x represent the sitting fee)

x+6y=50

x+11y=65

You want to isolate the x variable - x+6y-6y=50-6y ; x = 50-6y

Input this into the 2nd equation: 50-6y+11y=65 ; 50+5y=65

Subtract 50 from both sides. 5y=15 (Divided 5y on both sides) ; y=3

Now that y = 3 input this into any equation I choose the 1st one.

x+6(3) = 50 ; x + 18 = 50 (Subtract 18 on both sides to get x)

x = 32

Prove: 32 + 6(3) = 50 ; 32+18 = 50 ; 50 = 50 True

x= 3 y

Step-by-step explanation:

Let's make system of equations for the given information.

Let x number of bracelets and y number of necklaces made.

So, for the information

She makes a total of 40 bracelets and necklaces, we can set up equation as

Calculate the average time it took the car to travel 0.25 and 0.50 meters with two washers attached to the pulley. Record the averages, to two decimal places, in Table C of your Student Guide.

What is the average time it took the car to travel 0.25 meters?

seconds

What is the average time it took the car to travel 0.50 meters?

seconds

Answers

Answer:

1.92 second at 0.25 meters.

2.61 second at 0.50 meters.

Step-by-step explanation:

the average 2 washers  on time travel of:

0.25 m : 1.94 / 1.95 / 1.87 = 1.92 second

0.50 m: 2.69 / 2.72 / 2.42 = 2.61 second

In this exercise we have to calculate the time that a car makes in a certain distance, in this way we find that:

A) In 0.25 meters in 1.92 second.

B) In 0.50 meters in 2.61 seconds.

We know that some information is given in the statement as:

In 0.25 meters the car speeds are: 1.94/ 1.95/ 1.87In 0.50 meters the car speeds are: 2.69 / 2.72 / 2.42

Knowing that the formula for calculating time is given by:

[tex]Time= Distance/Speed[/tex]

So we have:

A) [tex](1.94 +1.95 + 1.87)/3= 5.76\\0.25/5.76=1.92 s[/tex]

B)  [tex]2.69+ 2.72 + 2.42= 7,83\\0.50/7,83=2,61[/tex]

Answer:

[tex]x=3\sqrt{2}\\[/tex]

Step-by-step explanation:

Since the smaller triangles have a side of the same length, they share one side, and the included angle is 90°, the triangles are congruent.

This means the length of the side to the left is also x as shown in the image below.

The bigger triangle is also right and has side lengths of x, x, and 6 (the hypotenuse), thus:

[tex]x^2+x^2=6^2[/tex]

Operating:

[tex]2x^2=36[/tex]

[tex]x^2=18[/tex]

Since 18=9*2

[tex]x=\sqrt{9*2}[/tex]

It didnt work, but it has proved to be a much loathed and admired analysis of human affairs from a coldly realist point of view. When Machiavelli speaks of a prince, he does not mean the son of a king, but is using the word in its older meaning the first, or the ruler of a territory. Italy was divided into many small city-states and other domains, which were in constant competition with each other. From Chapter 17: On cruelty and compassion, and whether it is better to be loved than to be feared, or the contrary Descending next to the other qualities mentioned before, I say that each prince ought to desire to be believed compassionate, and not cruel, nonetheless he must be alert not to use this compassion badly. Cesare Borgia was believed cruel; nonetheless, that cruelty of his restored the Romagna, unified it, and led it back to peace and to faith . . . A prince, therefore, must not care about the infamy of cruelty in keeping his subjects united and faithful, because if he makes a very few examples, he will be more compassionate that those who, through too much compassion, allow disorders to occur from which arise killings and robberies. For the latter usually harm an entire population, but those executions that come from the prince harm a particular person . . . From the above a debate arises whether it is better to be loved than feared or the contrary. The answer is that one would want to be both the one and the other, but because it is difficult to join them together, it is much safer to be feared than loved, if one has to do without one of the two. For the following may be said generally about men; that they are ungrateful, changeable, pretenders and dissemblers, avoiders of dangers, and desirous of gain, and while you do them good they are wholly yours, offering you their blood, their property, their life, and their children, as I said above, when the need is far off, but when it comes close to you they revolt. And that prince who has founded himself wholly on their words, because he finds himself naked of other preparations, is ruined. For the friendships that are acquired at a price, and not with greatness and nobility of spirit, are paid for but they are not possessed, and when they come due they cannot be used. Men have less fear of offending one who makes himself loved than one who makes himself feared, since love is held in place by a bond of obligation which, because men are wretched, is broken at every opportunity for utility to oneself, but fear is held in place by a fear of punishment that never abandons youNevertheless, the prince must make himself feared in such a way that, although he does not acquire love, he avoids hatred; because he can endure very well being feared whilst he is not hated, which will always be as long as he abstains from the property of his citizens and subjects and from their women. But when it is necessary for him to proceed against the life of someone, he must do it on proper justification and for manifest cause, but above all things he must keep his hands off the property of others, because men more quickly forget the death of their father than the loss of their patrimony. Besides, pretexts for taking away the property are never wanting; for he who has once begun to live by robbery will always find pretexts for seizing what belongs to others; but reasons for taking life, on the contrary, are more difficult to find and sooner lapse. But when a prince is with his army, and has under control a multitude of soldiers, then it is quite necessary for him to disregard the reputation of cruelty, for without it he would never hold his army united or disposed to its duties.ScoreEssay Prompt: Write a 4-5 paragraph essay answering the question, who was Machiavelli and what was his opinion on the way a leader should rule; through love or through fear?
