Which expression represents a rational number?
Please help right now!!!

Answer:

B

Step-by-step explanation:

x^2 + 4x + 2 = 0; a=1, b=4, c=2

D= b^2 - 4ac = 16 - 8 = 8>0

-> x1/2= (-b +/- √D)÷2×a= (-4 +/- √8)÷2= 2(-2 +/- √2)÷2

= -2 +/- √2

×1=-2+ √2 ≈ -0.59

×2=-2- √2 ≈ -3.41

therefore, b)

THIS IS HOW YOU CAN FIND ANY MISSING ANGLE - ALSO SOLVES FOR X IN THIS QUESTION.

So, a traingle is 180 degrees.

A line is also 180 degrees.

We know that the angles that make up the triangle are 46, 90, and a missing angle

We need to find the missing angle to find x

To find the missing angle, we must subtract the known angles by the 180 degrees of the traingle.

So:

180-90

=

90

90-46

=

44

So we know the missing angle is 44 degrees.

Let subtract the missing angle(44 degrees) by the 180 degrees of the line:

180-44

=

136

THIS IS WHAT ANSWERS THE OPTION METHOD THAT GIVES THE ANSWER

So x equals 136. This is the missing angle x.

So, remember, both the line and the traingle are 180 degrees.

They both need to find the missing value, which we know is 44

The rest of both the triangle and line is 136 degrees.

Well, 136 degrees on the triangle is the known 90+46 degrees.

Since this will be the same on the line, we can think of x as:

90+46

This looks like answer 1.

Hope this helps! :)

Answer:

If the diameter or radius of one circle is the same as another circle they are congruent.

Answer:

The required height is equal to 5.33 feet.

Step-by-step explanation:

Given that,

Diameter, d = 10 feet

Volume, V = 419 ft.³

We need to find the height the support poles crossed with some of the tepee correctly. Let the height is h.

The tepee is in the form of a  cylinder. The volume of a cylinder is given by :

[tex]V=\pi r^2 h\\\\h=\dfrac{V}{\pi r^2}\\\\h=\dfrac{419}{3.14\times 5^2}\\\\h=5.33\ ft[/tex]

So, the required height is equal to 5.33 feet.

Answer:

6000 m^3

Step-by-step explanation:

The basic formula for the area of a pyramid is 1/3 * b * h

where b is the base and h is the height.

The base is a square, so, we can find the area by squaring the side:

30^2 = 900.

Now, we can plug the values we have into the formula from above:

1/3 * 900 * 20

6000 m^3

Penny's Pickles divide their company into 10,000 shares of stock. If you buy 200 of these shares then you will have  [tex]2\[/tex]  percent of Penny's Pickles.

Percentage a is a number or ratio expressed as a fraction of 100. It is often denoted using the percent sign, [tex]\%[/tex].

Percentage [tex]=\frac{ You\ owned}{Total \ share} * 100[/tex]

We have,

Total shares of Penny's Pickles [tex]=10,000[/tex]

You owned shares   [tex]= 200[/tex]

So,

Using above formula,

Percentage [tex]=\frac{ You\ owned}{Total \ share} * 100[/tex]

Percentage of shares I owned [tex]=\frac{200}{10000} * 100[/tex]

                                                    [tex]= 2 \%[/tex]

So, the shares you owned are [tex]2\ \%[/tex] of total share of the Penny's Pickles.

Hence, we can say that Penny's Pickles divide their company into 10,000 shares of stock. If you buy 200 of these shares then you will have  [tex]2\[/tex]  percent of Penny's Pickles.

Answer: 5

Step-by-step explanation:

You see 2x2 = 4 right and since this is operation 2 / 10 = 5  and 6-5 = 1 so add 1 and that gives you 5

2x2 = 4 /  10/2 = 5 /  6-5 = 1 +4 = 5

Answer:

= 4x + -4

Step-by-step explanation:

Let's simplify:

[tex]2x(2) + 6 -10 \\ = 4x + 6 - 10[/tex]

Combine Like Terms:

[tex]=4x+6+−10

\\ =(4x)+(6+−10) \\ =4x+−4[/tex]

length = 3 + width

perimeter = 34

34 ÷ 2 = 17

width = x

3 +x + x = 17

3 + 2x = 17

2x = 14

x = 7

width = 7

it's good to write it out

length = 5 + width

area = 150

width = x

length = 5 + x

area = length * width

so

(5 + x) (x) = 150

5x + x^2 = 150

x^2 + 5x - 150 = 0

following you have to guess what 2 numbers when multiplied male 150 and when added make 5

and they are 15 and 10

(x +15) (x-10)

x = -15

x = 10

so the dimensions are

length = 15

and

width = 10

Answer:

-3x^2+16x+64

Step-by-step explanation:

First, you need to find the area of both areas (the total area and the area of the unshaded part). Let's find the total area.

(x+8)(x+8)=x^2+16x+64

The total area is x^2+16x+64

(2x)(2x)=4x^2

The area of the unshaded part is 4x^2

Now we have to subtract to find the area of the shaded part.

x^2+16x+64-4x^2

-3x^2+16x+64

That is the answer

Step-by-step explanation:

To find the perimeter of a rectangle, add the lengths of the rectangle's four sides. If you have only the width and the height, then you can easily find all four sides (two sides are each equal to the height and the other two sides are equal to the width).

Answer:

48 ounces

Step-by-step explanation:

Answer:

64 ounces.

Step-by-step explanation:

combined weigh = weight of cat 1 + weight of cat 2

combined weigh = 17 + 12 = 29 pounds

The difference in weight of the Dog's weigh by the combined cat's weigh is the subtraction between the two, so we have:

Difference in weigh = 33 - 29 = 4 pounds

We now have to convert it to ounces, since 1 pound contains 16 ounces we can multiply the value of the weigh in pounds by 16 to obtain the final value:

Difference in weigh = (4 pounds)* 16 = 64 ounces

Answer:

first option

Step-by-step explanation:

Given

y = 2(x - 3)² + 1

Rearrange making x the subject

Subtract 1 from both sides

y - 1 = 2(x - 3)² ( divide both sides by 2 )

[tex]\sqrt{\frac{y-1}{2} }[/tex] = (x - 3)² ( take the square root of both sides )

± [tex]\sqrt{\frac{y-1}{2} }[/tex] = x - 3 ( add 3 to both sides )

± [tex]\sqrt{\frac{y-1}{2} }[/tex] + 3 = x

Change y into terms of x with x being the inverse, that is

[tex]f^{-1}[/tex] (x) = ±[tex]\sqrt{\frac{x-1}{2} }[/tex] + 3
