Answer:

The area of the circle is [tex]1\pi[/tex] or approximately 3.14 [tex]km^2[/tex]

Step-by-step explanation:

The formula to find the area of a circle is [tex]\pi r^2[/tex], where [tex]r[/tex] represents the radius of the circle. In this case, the area would be [tex]1^2*\pi[/tex] = [tex]\pi[/tex] ≈ 3.14 [tex]km^2[/tex].

Answer:

He is incorrect. If you want 12 to be half of the book the other number would have to be twenty four.

Answer:

incorrect

Step-by-step explanation:

it has to be 12.5 to be exactly half way done with it

Answer:

4/9

Step-by-step explanation:

Answer:

10

Step-by-step explanation:

distance formula = \sqrt{(x_2 - x_1)^2 + (y_2-y_1)^2}

(x_1, y_1) = (5, 1)

(x_2, y_2) = (-3, -5)

\sqrt{ [(-3) - (5)]^2 + [(-5) - (1)]^2 }

\sqrt{ [-8]^2 + [-6]^2 }

\sqrt{ 64 + 36 }

\sqrt{ 100 }

= 10

Answer:

[tex] Distance = 10 \ u [/tex]

Step-by-step explanation:

Given :-

And we need to find the distance between the two points . We can use distance formula here to find the distance between the two points . The distance formula for two points ,

Distance Formula :-

[tex]\implies Distance =\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

[tex]\implies Distance =\sqrt{\{5-(-3)\}^2+\{1-(-5)\}^2 } \\\\\implies Distance =\sqrt{ (5+3)^2+(1+5)^2}\\\\\implies Distance =\sqrt{ 8^2+6^2}\\\\\implies Distance =\sqrt{64+36}\\\\\implies Distance =\sqrt{100}\\\\\implies Distance = 10\ units [/tex]

Hence the distance between the two points is 10 units .

Answer:

85 degrees

Step-by-step explanation:

Hi there!

<x is an exterior of the triangle ABC. An exterior angle of a triangle is equal to the sum of the two opposite interior angles. Therefore, we could say that x is equal to the sum of 60 and 25:

60+25=x

85=x

Therefore, angle x measures 85 degrees.

I hope this helps!

Answer:

2x+12

Step-by-step explanation:

2x+3(x−2)−3(x−6)

Distribute:

=2x+(3)(x)+(3)(−2)+(−3)(x)+(−3)(−6)

=2x+3x+−6+−3x+18

Combine Like Terms:

=2x+3x+−6+−3x+18

=(2x+3x+−3x)+(−6+18)

=2x+12

Answer:

=2x+12

Answer:

2x + 12

Step-by-step explanation:

distribute numbers inside parentheses

2x + 3x -6 -3x + 18

add x values together and integers together

2x + 3x -3x = 2x

-6 + 18 = 10

simplified to 2x + 12

Answer:

Cost of cell phone in U.S. dollar = 100 U.S. dollar

Step-by-step explanation:

Given:

Cost of cell phone in yen = 8,835.3 yen

1 U.S. dollar = 88.353 yen

Find:

Cost of cell phone in U.S. dollar

Computation:

Cost of cell phone in U.S. dollar = Cost of cell phone in yen[1 /  88.353]

Cost of cell phone in U.S. dollar = 8,835.3[1 /  88.353]

Cost of cell phone in U.S. dollar = 8,835.3 /  88.353

Cost of cell phone in U.S. dollar = 100 U.S. dollar

Answer:

3.9 & 3.3

Step-by-step explanation:

x=3.9 and y=-3.3

Explanation:

Let x and y be the two numbers

x + y = 35

x − y = 36 / 5

Let's solve by elimination

2x = 39 / 5

x=3.9

y=-3.3

[tex] SA= \frac{2}{3} \pi rl+16 \pi r^2[/tex]

Step-by-step explanation:

Surface area of the original cone

[tex] SA= \pi r l + \pi r^2... (1)[/tex]

When, radius is quadrupled and slant height is reduced to one sixth

[tex] i. e. \: \:r = 4r\: \: \&\:\: l= \frac{1}{6}l[/tex]

Plug the above values of r and [tex] l[/tex] in equation (1), new surface area becomes:

[tex] SA= \pi (4r)\times \frac{1}{6} l+ \pi (4r)^2[/tex]

[tex] SA= \frac{4}{6} \pi rl+16 \pi r^2[/tex]

[tex]\huge \purple {\boxed {SA= \frac{2}{3} \pi rl+16 \pi r^2}} [/tex]

Answer:

7/15

Step-by-step explanation:

You have 120 bags. 64 of them in total do not contain buttons.

120 - 64 = 56

You have 56 bags with buttons. The simple answer is,

56/120

You can simplify this down to 7/15

If you're looking for percent, the answer is 46.67%

Answer:

64 + 28 = 92

Step-by-step explanation:

Split the figure in half creating two triangles and a square.

length and width for the square would be 8ft and 8ft. Multiply both for 64 to be the area.

7ft and 4ft are the height and base for the triangles.

In this case, just multiple 7 and 4 because normally you would need to divide the product by 2 however since there are two triangles it negates the step.

Answer:

92ft^2

Step-by-step explanation:

you have to find the are of the triangle and subtract it from the area of the rectangle.

area of the triangle is 28ft^2

area of the rectangle is 120ft^2

120-28 =  92
