Bridgette has 9 dogs. Every day, she feeds them a total of 9/10 of a can of food, where each dog is fed the same amount of food. How many cans of food does Bridgette give to each dog?

Answers

Bridgette gives 1/10 cans of food to each dog.

According to the question,

We have the following information:

Bridgette has 9 dogs. Every day, she feeds them a total of 9/10 of a can of food, where each dog is fed the same amount of food.

Now, we have the following expression:

9 dogs = 9/10 can

Now, we can easily find the cans given to each dog using division. We will divide the total number of cans of food by the number of dogs.

1 dog = 9/(10*9) cans

1 dog = 1/10 cans of food

Hence, Bridgette gives 1/10 cans of food to each dog.

Ester sarai and kurry chose a number esters number is 1/10 of saris kurrys number is 10 times as much as sarais sarais number is 0.09. what number did each person choose?

Answers

Ester, Sarai, and Kurry each selected a number: 0.009, 0.09, and 0.9, respectively.

One of the four fundamental mathematical operations, along with addition, subtraction, and division, is multiplication. Multiply in mathematics refers to the continual addition of sets of identical sizes. For instance, 3+3+3+3+3 can be expressed as 3 5.

the ester's number is equal to one-tenth of the Sarai number.

= 1 / 10 × 0.09 = 0.009

to determine Kurry's number, multiply Sarai's number by 10

= 10 × 0.09 = 0.9

Therefore, it can be inferred that Kurry chose 0.9, Ester chose 0.009, and Sarai chose 0.09.

What is the image of the point (-7,5)(−7,5) after a rotation of 180^{\circ}180

counterclockwise about the origin?

Answers

The coordinates of the image of the point (-7, 5) are (7, -5).

We are given point P. The coordinates of the point P are (-7, 5). We perform a transformation on the given point. We rotate the given point about the origin counter-clockwise. The angle of rotation is 180°. We need to find the coordinates of the image of the point after rotation.

Let the new coordinates of the image of the point after rotation be denoted by (X, Y). If the coordinates of the original point are (x, y), then the relations between the coordinates of the point and the image are given below.

X = x*cosθ - y*sinθ

X = (-7)*cos(180°) - (5)*sin(180°)

X = (-7)*(-1) - (5)*(0)

X = 7

Y = x*sinθ + y*cosθ

Y = (-7)*sin(180°) + (5)*cos(180°)

Y = (-7)*(0) + (5)*(-1)

Y = -5

please help. what is the equation??

Answers

Answer:

y = -x + 4

Step-by-step explanation:

The equation of a line follows the form y=mx+c, where x and y are the coordinates, c is the y-intercept (the value of x where the line crosses the y-axis), and m is the slope.

We are given two points/coordinates - (-3,7) and (1,3) - so we know the following is true for our equation:

7=-3m+c

3=m+c

Rearranging the second equation above, we get c=3-m. Sub this into the first one, and we get

7=-3m+3-m

4=-4m

m=-1

Knowing c=3-m, we can say c=3-(-1)=3+1=4

Having found values for m and c, we can now write our equation:

y = -x + 4

The probability to win two or more tickets in the lottery is 0.118

Therefore, the probability to win a lottery ticket is

The girl here plays the game 12 times. The above distribution is clearly a Binomial Distribution

ⁿCₓ  X  pˣ  X  (1 - p)ⁿ⁻ˣ

We need to calculate the probability to win 2 or more tickets

= 1 - the probability to win at least one ticket

= 1 - P(X = 0) + P(X = 1)

here,

p = 0.05

1 - p = 0.95

P(X = 0)

P(X = 1)

Hence we get

P(X ≥ 2) = 1 - 0.54036 - 0.34128

along a river is to be fenced. suppose that no fence is needed along the river, the fence on the side opposite the river costs $40 per foot, and the fence on the other sides costs $10 per foot. if the field must contain 64,800 square feet, what dimensions will minimize costs?

Answers

The dimensions required to minimize the cost of fencing is 180ft and 360 ft.

According to question

The cost of fence on opposite side of river is $40.

The cost of fence on other sides of river is $10.

Total yield = 64800 sq. feet

Let the length of fence on the opposite side of fence be x and width of fence on the other side be y.

Area of fence = xy = 64800 sq feet

⇒ [tex]y = \frac{64800}{x}[/tex]

Let C be the cost of making fence.

For cost to be minimum, dC/dx should be equal to zero.

C = 40x + 10y * 2

⇒ C = [tex]40x + 10(\frac{64800}{x})*2[/tex]

⇒ [tex]\frac{dC}{dx} = 40 + 20 * 64800 * \frac{-1}{x^{2} } = 0[/tex]

⇒ [tex]40x^{2} = 20 * 64800[/tex]

⇒ [tex]x^{2} = 32400[/tex]

⇒ [tex]x = 180[/tex]

⇒ [tex]y = \frac{64800}{180} = 360[/tex]

So, the dimensions needed will be 180 ft and 360 ft.

5 ft / 20.5 corresponds to 1 actual mile.

5 / 20.5 = 10/41 ft

now, we have 15.5 actual miles, that is 15.5 times the 1 standard actual mile.

and so, this is

10/41 × 15.5 = 155/41 = 3.7804878048780... map ft

1 map m = 14/7 = 2 actual miles.

14 map m = 14×2 = 28 actual miles.

The expression 11! / 9!(11-9)! evaluates to 55

How to evaluate numbers with the factorial sign?

The symbol ! is called factorial in mathematics.

Factorial can be defined as the product of all positive integers less than or equal to a given positive integer and denoted by that integer and an exclamation point.

Thus, factorial five is written as 5! meaning 5×4×3×2×1

It can also be written in shortened form as 5×4! or 5×4×3!

Let's evaluate  11! / 9!(11-9)!  now:

11! / 9!(11-9)! =  11! / 9!(2)!

                    = 11×10×9! / 9!2!

                    = 11×10/ 2                   (Note: 2! = 2×1 =2 )

                    = 110/2

                   =  55

Note: We shortened 11! to 11×10×9! because we want the 9! to cancel out each other. This is usually done to ease the evaluation. Also, note that 0! = 1

Therefore,  the result of the evaluation of the expression 11! / 9!(11-9)! is 55

ABCD is a square. If LABC = (6x - 12)° and CD= (x + 15). Find the length of AD.

Answers

Answer:

  AD = 32

Step-by-step explanation:

You want the length of side AD of square ABCD, when CD = (x+15) and angle ABC is (6x-12)°.

Value of x

The value of x can be found by recognizing that the measure of any angle in a square is 90°.

  (6x -12)° = 90°

  6x = 102 . . . . . . . . divide by °, add 12

  x = 17

Measure of AD

The sides of a square are congruent, so ...

  AD = CD = (x +15) = 17 +15 = 32

The length of AD is 32 units.

What output should result?When might you need to use decision branching? If you used decision branching, did you account for all possible input values?Did you use appropriate indentation and keywords (such as IF, ELSE, CALCULATE, and so on) throughout your pseudocode?Create a flowchart to design a programming solution by organizing a series of steps and using appropriate symbols and arrows. As you create your flowchart, be sure to use appropriate arrows and symbols for each of the following:Start and end pointsInput and outputDecision branchingProcessing stepsNote: You may find the correct shapes to create your flowchart on the Insert menu in Microsoft Word. Or you may draw your flowchart by hand, take a clear picture, and insert the picture into your Word document. Use the add shapes or insert pictures tutorials to help you. You could also use a flowcharting tool that you are familiar with, such as Lucidchart, if you prefer. according to the 2010 u.s. census, which is the only southern state that lost seats in the house of representatives due to population shifts out of the state? What should the writer of a persuasive nonfiction piece do in their conclusion in addition to tying up everything that has been said in the body? A. Reference further reading material. B. Verify their credentials as a writer. C. Provide their reader with a strong feeling. D. Restate their argument. Imagine a scatterplot of a class of 20 students showing the relationship between SAT scores onthe x axis and class grade on the y axis, with 19 of the dots showing a clear positive linearrelationship going from the bottom left to the upper right. However, the 20th student (who scoredvery high on the SAT) hasn't been going to class or doing the homework and so is flunking theclass. Thus, that datapoint is by itself in the bottom right hand corner of the scatterplot. Whatwould be the effect on the correlation between SAT and grades if the slacker dropped the class andhis datapoint was deleted?A. The correlation coefficient (r) would increase.B. The correlation coefficient (r) would decrease.C. The correlation coefficient (r) would not change.D. It is impossible to know.
