find geometric probability​

Answers

Answer: 67%

Step-by-step explanation:

Since we're not solving for area I would just divide this circle into 6 equal parts. 3 on both sides of the diameter. The orange parts take up about 120/180 on one sides of the circle. So 2/3 of half the circle are covered in orange which means 2/6 of the whole circle is covered in orange. Which leaves us with 4/6 blank or white area. 4/6 as a decimal is 0.6666667 or 67%

Answer:

66.67 % (Rounded to the nearest hundreth)

66.666..%  or 66 2/3 %

Step-by-step explanation:

The area of the whole circle with radius 4 is 50.27

The white area is 4/6 =  2/3 of the total area = 33.51333333

The geometric probability is the    favorable area divided by the total area

   33. 513333 / 50.27 = 0.6666666   = 66.666666%

A tablecloth is 82 inches long. What is the length in feet and inches?

Answers

Answer: 6 feet and 10 inches

Step-by-step explanation:

Each foot has 12 inches in it

You can either divide 82 by 12 or

1 foot: 12 inches

2 foot: 24 inches

3 foot: 36 inches

4 foot: 48 inches

5 foot: 60 inches

6 foot: 72 inches

7 foot: 84 inches

Since 7 foot is too much you can now take 6 feet (72 inches) and subtract it from 82

82-72=10

10 meaning 10 inches

6 feet and 10 inches

You may also divide but you will get a decimal like this:

6.83333333

Unit conversion is a way of converting some common units into another without changing their real value. The length of the table cloth is 6 ft 10 inches.

What is Unit conversion?

Unit conversion is a way of converting some common units into another without changing their real value. for, example, 1 centimetre is equal to 10 mm, though the real measurement is still the same the units and numerical values have been changed.

In terms of measurement, one foot is 12 inches.

1 ft = 12 inches

Given that the table cloth is 82 inches long. Therefore, the length in feet and inches are,

Length = 82 inches

            = 82 / 12 foot

            = 6 10/12 foot

            = 6 ft 10 inches

Hence, the length of the table cloth is 6 ft 10 inches.

What is centroid of a triangle and its coordinates?

The point of intersection of a triangle's medians is its centroid (the lines joining each vertex with the midpoint of the opposite side).

If the triangle has its vertices as  [tex](x_1, y_1), (x_2, y_2) , \: (x_3, y_3)[/tex], then the coordinates of the centroid of that triangle is given by:

[tex](x,y) = \left( \dfrac{x_1 + x_2 + x_3}{3} + \dfrac{y_1 + y_2 + y_3}{3} \right)[/tex]

The vertices of ΔJKL lies in first quadrant because the coordinated of the vertices are positive which means the vertices are in the form of (x,y).

If the ΔJKL reflects along the x-axis then the vertices are in the form of (x,-y). Now the  ΔJKL reflects along the y-axis then the vertices are in the form of (-x,-y).

The given coordinates of the the vertices after transformation is J(−3, 4), K(3, 0), and L(−5, −4).

The equation of the median to J is y=0.

(-3 + 3 - 5 / 3 , 4 + 0 - 4/ 3) = (-5/3 , 0)

Answer:

2) 62°

Step-by-step explanation:

since there is a straight line (can also be called as a semi-circle), that gives us an idea that it is a 180 degree, because a whole circle is 360 degrees.

180-118 = 62°

Answer:

59° and 62°

Step-by-step explanation:

here's your solution

=> in the first picture , we know that sum of all angle on a straight line is 180°

=> so, angle ( ? + 121 ) = 180°

=> ? = 180° - 121°

=> ? = 59°

now , in second picture

=> ( x + 118° ) = 180°

=> x = 180° - 118°

=> x = 62°

Answer:

P' = (2, -6)

Step-by-step explanation:

In this translation, you just need to substitute x and y into the given translation to find what P' is. (x is -6 since it's the x-value of P, and y is -2 since it's the y-value of P):

where T(x, y) = (x + 8, y - 4) and x = -6 and y = -2,

T(-6, -2) = ((-6) + 8), (-2) - 4) (substitute x and y into the translation)

T(-6, -2) = (2, -6) (add and subtract)

So, P' = (2, -6)
