Answer:

heyy Vrooo....

alr ans is 49

Step-by-step explanation:

see let number be x

so as per ques.. product of x and 9/7 = 9x/7

which is 63

so [tex]\frac{9x}{7}[/tex] = 63

9x = 63*7

x = [tex]\frac{63*7}{9}[/tex]

x = 7*7 = 49

x/2 > 5

Answer:

It's a (space) lot,... haha na I just kidding,... you're good,... I mean I'm not kidding cause it is correct,... but you are good,... like totally cool,... anyway,...

Step-by-step explanation:

By x the just mean what number,... so,...

what number + 6 = 7,

6 + what number = 7,

2 + what number + 5 = 7,

1 + what number = 7,

what number + 4 + what number = 7,

So that is what it mean,... hope it helps, alot LOL,... and,... Chow

Number of subset= [tex]2^{n}[/tex]

Her, n is the number of elements in the set.

{p , e , t}

n = 3

Number of subset = 2³ = 2 * 2 *2 = 8

360 grms of 6kg

answer,

first convert 6kg into grms.

6kg = 6000grms.

now,

360 grms of 6kg= (360/6000)×100•/•

= 6 •/•

The first choice can be aby one of the 4 colors.

    For each of these . . .

The 2nd choice can be any one of the 3 remaining colors.

    For each of these . . .

The 3rd choice can be either one of the 2 remaining colors.

So there are (4 · 3 · 2)  =  24 different ways to order the colors.

If everybody you ask thinks the same way, you'd expect all of the possible combinations to be chosen equal numbers of times . . . that is, every choice would be chosen once in every group of 24 people.

In 1,000 people, there are (1000/24) = (41 and 2/3) groups of 24 people.

So you'd expect any one possible preference order to be chosen by 41 or 42 viewers, if all of the viewers think the same way, and their preferences are perfectly random.

Answer:

d.{(8,1),(−4,1),(3,5),(0,4),(−1,2)} - function

Step-by-step explanation:

a.{(2,4),(2,6),(2,8),(2,10),(2,12)}

Each value of x goes to more than one value of y- this is not a function

b. {(−5,−4),(−4,−3),(−3,−2),(−4,−5),(−2,−1)}

The value of x at -4 goes to more than one value of y- this is not a function

c.{(0,3),(−6,8),(−3,5),(0,−3),(7,11)}

The value of x at 0 goes to more than one value of y- this is not a function

d.{(8,1),(−4,1),(3,5),(0,4),(−1,2)}

 Each value of x goes to only one value of y- this is a function

Answer:

B

Step-by-step explanation:

22/33 = 0.667

14/21 = 0.667

Since both quantities both have the ratio of 2:3, they are proportional

The other choices are not proportional

25/28 = 0.893

5/7 = 0.714

16/13 = 1.231

13/16 = 0.813

48/60 = .8

35/42 = .833

Answer:

a) 72

Step-by-step explanation:

The rightmost digit, 5, is in the ones place, so its value is 5.

The next digit to the left, the 4 is in the sixes place, so its value is 4 * 6 = 24.

The next digit to the left, the 2, is in the 36 place, so its value is 2 * 36 = 72.

Answer: a) 72

Answer:

[tex] \frac{ \sin {}^{3} A - \cos {}^{3} A }{ \sin A - \cos A} \\ \\ { \sf{ = \frac{ {( \sin A - \cos A)}^{3} + 3 \sin A \cos A( \sin A - \cos A)}{ \sin A - \cos A} }} \\ \\ = { {( \sin A - \cos A)}^{2} + 3 \sin A \cos A} \\ { \sf{ = ( \sin {}^{2} A + \cos {}^{2} A) - 2 \sin A \cos A + 3\sin A \cos A}} \\ = { \sf{1 +\sin A \cos A }} [/tex]

#hence proved

Let y = √x, so the limit can be rewritten as

[tex]\displaystyle \lim_{y\to\infty}\left(\frac{\sqrt{y^6+y^2}}{y^2+3} - \frac{\sqrt{y^4+1}}{y+4}\right)[/tex]

Now,

[tex]\sqrt{y^6+y^2} = \sqrt{y^2\left(y^4+1\right)} = y\sqrt{y^4+1}[/tex]

so we can rewrite the limit further as

[tex]\displaystyle \lim_{y\to\infty}\left(\frac{y}{y^2+3} - \frac1{y+4}\right)\sqrt{y^4+1}[/tex]

Combine the rational terms:

[tex]\dfrac y{y^2+3} - \dfrac1{y+4} = \dfrac{y(y+4)-(y^2+3)}{(y^2+3)(y+4)} = \dfrac{4y-3}{(y^2+3)(y+4)}[/tex]

Then in the limit, we get

[tex]\displaystyle \lim_{y\to\infty}\frac{(4y-3)\sqrt{y^4+1}}{(y^2+3)(y+4)} = \lim_{y\to\infty}\frac{(4y^3-3y^2)\sqrt{1+\dfrac1{y^4}}}{y^3+4y^2+3y+12} \\\\ = \lim_{y\to\infty}\frac{\left(4-\dfrac3y\right)\sqrt{1+\dfrac1{y^4}}}{1+\dfrac4y+\dfrac3{y^2}+\dfrac{12}{y^3}} = \boxed{4}[/tex]

Answer:

The answer to your question would be x=12. Equation is worked out below

Step-by-step explanation:

5 /2 x−7= 3 /4 x+14

5 /2 x-3/4x − 7 =  3 /4 x-3/4x +14

7/ 4 x−7=14

7 /4 x−7+7=14+7

7/ 4 x=21

do the opposite of 7/4x (division)

7/4 / 7/4x = 21 / 7/4

4/7 / 7/4x (cross each other out) = 21 / 4/7

x=12

Answer:

[tex] \frac{5}{2}x - 7 = \frac{3}{4} x + 14 \\ \frac{5}{2} x - \frac{3}{4} x = 14 + 7 \\ \frac{7}{4} x = 21 \\ x = \frac{21 \times 4}{7} \\ x = 12[/tex]

I hope I helped you^_^

Answer:

16.7

Step-by-step explanation:

In a right triangle, a²+b²=c², with c representing the hypotenuse. In a right triangle, the hypotenuse is the side opposite of the right angle, or the angle symbolized by the square. Here, the right angle is opposite of the side with a length of 20, so we can say that

c = 20

Therefore,

a²+b² = 20², with a and b representing the other two sides*. Because 11 is given as another side, we can say

11² + b² = 20²

121 + b² = 400

subtract 121 from both sides

279 = b²

square root both sides

b = √279 ≈ 16.7 as the third side

* for our purposes, it does not matter which side is a and which side is b

Answer: A) The degree of the polynomial is even

We can determine this by noticing that the end behavior is different on both sides. The left end goes downward while the right end goes upward. This opposing nature indicates we have an odd degree function like a cubic. If this was an even degree function, then the left end must also point upward to mirror the right end. That's why choice A is the final answer.

Choice B can be ruled out since it's a true statement. This is because the right end behavior goes to positive infinity. Such end behavior is tied to positive leading coefficients (whether even or odd functions, it doesn't matter).

Choice C is also true and can be ruled out because this function curve does have one relative minimum. It's the location where the curve bottoms out in the valley at around x = 3.5 or so. It's the lowest point in the neighborhood/interval of points.

Choice D can be ruled out for similar reasons as choice C, except this time we're looking at the highest point in a certain neighborhood. That highest point occurs somewhere between x = 1.5 and x = 2 where the peak of the hill is located.

To rephrase those last three paragraphs: choices B through D are true statements, so they can be ruled out.

Answer:

Two choices are correct answer.

y = x   and y = 1/4 x

Step-by-step explanation:

We have given four equations.  

We have to choose the equations that are direct variation function.  

Direct variation function is defined as the relation where one variable vary constant times to the other variable.  

let two variables are x and y.  

y = kx   where k is constant.  

Comparing given equation , we notice that  

y = x is direct variation function where k = 1.  

y = 1/4 x is direct variation function where k = 1/4.
