Answer:

P = 0.637

Step-by-step explanation:

By a small online search, i've found that the image is a circle of radius R = 1in, and a square inside of the circle, such that the distance between the center of the square and the one vertex of the square is one inch.

To solve this problem, we need to find the area of each figure.

The area of a circle of radius R is:

A = 3.14*R^2

Then the area of our circle is:

A = 3.14*(1in)^2 = 3.14 in^2

Now for the square.

If the distance between the center and one vertex is 1 inch, then the distance between two opposite vertex is twice that: 2 inches.

Now we can think of a triangle rectangle, where both catheti are equal to L, the side length of the square, and the hypotenuse is 2 inches.

Using the Pythagoreans theorem, we get:

L^2 + L^2 = (2in)^2

2*L^2 = (2in)^2

L^2 = (2in)^2/2 = 2 in^2

L = √(2 in^2) = √2 in

And the area of a square of side length L, the area is:

A = L^2

Then the area of our square is:

A = (√2 in) = 2 in^2

Then:

Area of the circle = 3.14 in^2

Area of the square = 2 in^2

The area of the circle represents the 100% (if a point is chosen at random in the circle, the probability that the point will be inside the circle is P = 1)

The probability that the point will be inside the square is equal to the quotient between the area of the square and the area of the circle, this is:

P = (2 in^2)/(3.14 in^2) = 0.637

Answer:

(x+7) times (x+3)

Step-by-step explanation:

Because a area of a rectangle is lw and you combine x and 3 to make x+3 and 7 and x to make x+7 and you multiply them together.

The area of the rectangle will be (x² + 10x + 21) unit².

A rectangle is a two dimension figure with 4 sides, 4 corners and 4 right angles. The opposite sides of the rectangle are equal and parallel to each other.

Given that;

The Length of the rectangle = x + 7

And, The width of the rectangle = x + 3

Now,

Since, The Length of the rectangle = x + 7

And, The width of the rectangle = x + 3

We know that;

The area of rectangle = Length × Width

                                  = (x + 7) × (x + 3)

                                  = x² + 3x + 7x + 21

                                  = x² + 10x + 21

Thus, The area of rectangle = (x² + 10x + 21) unit²

Answer:

$12566.25

Step-by-step explanation:

because .25 is 1/4 of $1 all you have to do is divide 50,265 by 4 and that's your answer

you could also just multiply .25 by 50,265 to make it simpler and it'll come with the same answer

Answer:

c

Step-by-step explanation:

since all the tangent(tan) angles are multiplying,

you factor tan out and multiply the numbers. that's : tan( 23+35+60+67+55)

tan(240)

tan(240) =√3

Option 2

Step-by-step explanation:

it easy Add them all up and then you get 47/16 then divide them and convert it to mixed number and then you get 2 15/16

Answer:

2 15/16

Step-by-step explanation:

We need to make sure all fractions have the same denominator.

The LCM (least common denominator) is 16.

Now we have to multiply each nunber except 2 1/16 to get a numerator of 16.

1/2: 1x8= 8, 2x8= 16→ 8/16

3/8: 3x2= 6, 8x2= 16→ 6/16

Now every add everything all up.

8/16 + 6/16 + 2 1/16 = 2 15/16

2 15/16 is our answer.

Answer:

no it's different 30% would be 12 and 40% would be 16 if it was going into 30 now mark as brainliest

Answer:

In both cases you are really multiplying the same numbers together.

Step-by-step explanation:

30% of 40 would be 30 x 40 x 0.01 = 12

or 0.30 x 40 = 12

40% of 30 would be 40 x 30 x 0.01 = 12

or 30 x 0.40 = 12

Answer:

x = 8

Step-by-step explanation:

4(8) + 6(5) = 62

32 + 30 = 62

62 = 62

Answer:

x = 8

Step-by-step explanation:

y = 5 and 4x + 6y = 62

4x + 30 = 62

Subtract 30 from each side:

4x + 30 - 30 = 62 - 30

4x = 32

Divide each side by 4:

4x ÷ 4 = 32 ÷ 4

x = 8

Answer:

vertically opposite angles and alternate pair

so by aa similarity they are similar

Answer: length = 8cm

Width = 4cm

Step-by-step explanation:

Let the width of the rectangle be represented by x.

Since the length of a rectangle is twice as long as the width of the rectangle, then the length will be: = 2 × x = 2x

Note that, Area of a rectangle = Length × Width

Therefore,

2x × x = 32

2x² = 32

Divide both side by 2

2x²/2 = 32/2

x² = 16

x = ✓16

x = 4

Therefore, width = 4cm

Since length = 2x

Length = 2 × 4cm = 8cm

Check: length × width = Area

8cm × 4cm = 32cm²

Y = 15x + 150

Question 3:

Replace x with a positive value and solve for y, which will be larger than the x value

Answer (15,375)

Question 4:

This means for 15 people the total cost for the special rate would be $375

Answer: C. Frank

Answer:

a = 6.8

Step-by-step explanation:

Apply the Law of Cosines

a² = b² + c² - 2bc*Cos A

A = 29°

b = 4

c = 10

Plug in the values

a² = 4² + 10² - 2*4*10*Cos 29

a² = 116 - 69.9696

a² = 46.0304

a = √46.0304

a ≈ 6.8
