The required value in (36,25,x) is an O'Hara triple, of x is 11.

Three positive integers a, b, and x form an O'Hara triple (a,b,x) if and only if √a+√b=x. For example, (1,4,3) is an O'Hara triple because √1+√4=3. If (36,25,x) is an O'Hara triple,  To determine the value of x.

In mathematics, it deals with numbers of operations according to the statements.

From example,
(1,4,3) is an O'Hara triple because √1+√4=3, in the example sum of the square roots of the first two numbers is equal to the third number. so the value of x in  (36,25,x)  can be determined in the same manner.

Following the example,
√36+√25=x
6 + 5 = x
x = 11

Thus, the required value in (36,25,x) is an O'Hara triple, of x is 11.

Answer:

Subtract 24 from both sides.

Step-by-step explanation:

x2+8x=24

Step 1: Subtract 24 from both sides.

x2+8x−24=24−24

x2+8x−24=0

For this equation: a=1, b=8, c=-24

1x2+8x+−24=0

Step 2: Use quadratic formula with a=1, b=8, c=-24.

Answer:

I think A. I got (2,0) and (-0.5,0). Weird.

Step-by-step explanation:

- 4x + 3y = 15

2x + y = -5

I multiply x 3 the second equality

we will get

- 4x + 3y = 15

6x + 3y = - 15

difference of the 2 equalities

- 4x - 6x + 3y - 3y = 15 - (-15)

- 10x = 30

x = -3

so   - 4*(-3) + 3y = 15

3y = 3

y = 1

check

- 4 * (-3) + 3 * 1 = 12 + 3 = 15

Step-by-step explanation:

the degree of a polynomial determines 1:1 the number of solutions.

a quadratic equation (degree 2) has 2 solutions.

the general solution is

x = (-b ± sqrt(b² - 4ac))/(2a)

in our case

a = -4

b = -4

c = -1

so,

x = (4 ± sqrt((-4)² - 4×-4×-1))/(2×-4)

when we look at the square root

16 - 16

we see that it is 0.

the square root of 0 is 0, and there is no difference between -0 and +0.

so, we get only one (real) solution : 4/-8 = -1/2

but : formally, there are still 2 solutions (as this is a quadratic equation). they are just identical.

so, I am not sure what your teacher wants to see in this case as answer.

my answer would be 2 real identical solutions.

Answer:

[tex]\displaystyle [7x - 2][3x + 7][/tex]

Step-by-step explanation:

Find two quantities that when differed to 43, they also multiply to 294. Those will be 6 and 49. The TINIER quantity gets the minus symbol because the B-value is 43, therefore 49 gets the plus symbol, leaving 6 with the minus symbol. In extension, sinse we have a leading coefficient greater than one, we need to take extra procedures. Here is how it is done:

[tex]\displaystyle 21x^2 + 43x - 14 \\ \\ [21x^2 - 6x] + [49x - 14] \\ 3x[7x - 2] + 7[7x - 2] \\ \\ \boxed{[7x - 2][3x + 7]}[/tex]

Answer:

522 times

Step-by-step explanation:

a peach chew was chosen 6 out of 23 times so we can create a proportion out of 2000 based on that ratio:

'p' = times peach is chosen out of 2000

6/23 =p/2000

cross-multiply to get:  

23p = 12000

p = 12000/23

p = 522 times

Answer:

522 times

Step-by-step explanation:

From this experiment, Skylar selects a peach chew 6/23 of the time. 6/23*2000=522. This works because 6/23 is the amount of chance Skylar has of selecting a peach chew if she selects one chew. If she selects 2000 chews, therefore, her odds of getting a peach chew would mean that she would get about 522 peach chews.

The situation involves combination

There are 45 possibilities of choosing the 3 side dishes from the menu

The given parameters are

The keyword choose means that the situation involves combination.

Given that you want at least one vegetable and one starch, the selections are:

(Vegetable, Starch) = (1,2) and (2,1)

So, the number (n) of ways the dishes can be selected is:

n = 5C1 * 3C2 + 5C2 * 3C1

Apply the combination formula on each expression

n = 5 * 3 + 10 * 3

Evaluate the sum

n = 45

Hence, there are 45 possibilities of choosing the 3 side dishes from the menu

Answer:

[tex]y-2 = -3(x-2)[/tex]

Step-by-step explanation:

Find the diagram to the question attached.

The standard equation of a line in point-slope form is expressed as:

[tex]y-y_0 = m(x-x_0)[/tex] where:

m is the slope of the line

[tex](x_0, y_0)[/tex] is coordinate point on the line

First is to get the slope of the line.

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

If after buying 2 lattes, she has $2 left, hence one of the coordinate of the line is (2, 2). We can get the other coordinates from the graph. From the graph, it can be seen that when x = 0, y = 8. Hence the other coordinates is (0, 8)

[tex]m = \frac{8-2}{0-2}\\m = \frac{6}{-2}\\m = -3[/tex]

Hence the slope is -3

Substitute m = -3 and the point (2, 2) into the formula to get the required equation (note that any of the points can be used)

[tex]y-y_0 = m(x-x_0)\\y-2 = -3(x-2)[/tex]

Hence the equation of the line in point-slope form is [tex]y-2 = -3(x-2)[/tex]

The probability  that the dart lands inside the square but not on the circular dartboard is 0.215

The chances of the happening of any event are called the probability.

The dartboard is in the form of a square and the circle is inscribed in it

The area of the dartboard is  [tex]a_d=54\ inch^2[/tex]

Since the circle is inscribed on the dashboard so the diameter of the circle will be the length of the square  

[tex]a_d=s^2=64[/tex]

[tex]s=\sqrt{64}=8\ inch[/tex]

Thus the diameter of the circle

[tex]d=8\ \ \ r= \dfrac{8}{2} =4 \ inches[/tex]

Now we will calculate the area of the circle

[tex]a_c=\pi r^2[/tex]

[tex]a_c=\ 3.14\times 4^2=50.24\ inch^2[/tex]

The area of the square outside the circle will be the difference of the area of the square and the area of the circle

[tex]64-50.24=13.76\ inch^2[/tex]

Now to find out the probability of the dart hitting outside the circle will be calculated as.

[tex]\rm Probability = \dfrac{Area \ outside \ circle }{Area \ of \ square}[/tex]

[tex]P= \dfrac{13.76}{64} =0.215[/tex]

Thus the probability  that the dart lands inside the square but not on the circular dartboard is 0.215
