Answer:

Step-by-step explanation:

The circles are written in standard form. The standard form squares the radius on the right hand side.

Circle A

radius = sqrt(9)

radius = 3

Circle B

radius = sqrt(8)

radius = sqrt(2 * 2 * 2)

radius = 2 sqrt(2)

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)

Answer:

In order for three numbers to form a triangle, the sum of any of the two numbers must be greater than the third number. In this case, 12+20>24, 20+24>12, and 12+24>20. Therefore, this is a triangle.

c^2_a^2+b^2

24^2_12^2+20^2

576_144+400

576_544

576>544

This is an obtuse triangle, as c^2>a^2+b^2.

Answer:

The time taken is 4.79 minutes.

Step-by-step explanation:

[tex]P = Po(1.4)^{t}[/tex]

initial Population, Po = 400

Final population, P = 2000

Let the time is t.

[tex]2000 = 400(1.4)^{t} \\5 = (1.4)^t\\log 5 = t log 1.4\\0.6989 = 0.146 t \\t = 4.79 minutes[/tex]

Answer :

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]

15/3=5

or

14+5x=29

subtract 14 from both sides

5x=15

divide both sides by 3

x=3

Answer:

Perimeter = 2 ( l + w )

if u r given for rectangle thats the formula

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:

5/12!

Step-by-step explanation:

So, imagine the denominator as the whole classroom, i.e. rephrase __ out of 12 to __/12. To get the total class, just add up both groups, which gets you 12! now, 5 out of the 12 kids are girls, so, put 5 in the last sections blank! i hope this helped!!!

Answer:

Area required for circular hot tube = 6,218 inch² (Approx.)

Step-by-step explanation:

Given:

Diameter of circular hot tube = 89 inches

Value of π = 3.14

Find:

Area required for circular hot tube

Computation:

Radius of hot tube = Diameter / 2

Radius of hot tube = 89 / 2 inches

Area required for circular hot tube = Area of circle

Area of circle = πr²

Area required for circular hot tube = πr²

Area required for circular hot tube = (3.14)(89/2)²

Area required for circular hot tube = (3.14)(7921 / 4)

Area required for circular hot tube = (3.14)(1,980.25)

Area required for circular hot tube = 6,217.985

Area required for circular hot tube = 6,218 inch² (Approx.)

Answer:

I don't have the options but I know parallel lines will never touch, they have the same slope, and the distance between the lines never changes

Answer:

B. 5626.9

Step-by-step explanation:

• volume of cylinder= pi(r)2h

• plug in the values into the equation

• pi(8)2(28)

pi=3.14 so 3.14(8)2(28)

• multiply all the values

• you get 5629. 73

• b is the closest the that answer since it says approximate

Answer:

A) The area of parallelogram 1 is 4 square units greater than the area of parallelogram 2.

The area of parallelogram 1 is 2 square units greater than the area of parallelogram. Option 2 is correct.

The space filled by a flat form or the surface of an item is known as the area.

The number of unit squares that cover the surface of a closed-form is the figure's area. Square centimeters and other similar units are used to measure area.

A₁ is the area of parallelogram 1

A₁ is the area of parallelogram 2

l₁ is the distance between the points (2,6),(0,2)

l₂ is the distance between the points (4,0)(0,2)

b₁ is the distance between the points (2,0),(0,-2)

b₂ is the distance between the points (2,6),(4,-6)

A₁ =  l₁ × b₁

A₁=4.47 ×4.47

A₁  = 19.89 sq.unit

A₂=l₂×b₂

A₂=2.82 × 6.342

A₂=17.88 sq.unit

A₁-A₂ = 19.89 sq.unit - 17.88  sq.unit'

A₁-A₂= 2.01

The area of parallelogram 1 is 2 square units greater than the area of a parallelogram.

Hence,option 2 is correct.

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
