Answer:

27 Degrees

Step-by-step explanation:

Since 63 and x make 90 degrees, 90-63 is 27 which gives you the answer. The equation is X=90-63.

Answer:

63 + x = 90

Step-by-step explanation:

The desired equation is 63 + x = 90, because the angles 63 and x are complementary (they add up to 90 degrees).

The figure below shows a shaded circular region inside a larger circle:

A shaded circle is shown inside another larger circle. The radius of the smaller circle is labeled as r and the radius of the larger circle is labeled as R. On the right side of the image is written r equal to 3 inches and below r equal to 3 inches is written R equal to 5 inches.

What is the probability that a point chosen inside the larger circle is not in the shaded region?

24%
36%
50%
64%

PLS NO LINK thanks :)

Answers

Answer:

Step-by-step explanation:

here you go it in there

Answer:

Probability is 64%

Step-by-step explanation:

Given the smaller circle which is shaded whose radius is denoted by r and  the largest circle whose radius is denoted by R

                     r = 3 inches

                    R = 5 inches

Step 1 : To calculate the area of shaded region.

Area of circle =

⇒ Area =    

          =   square inches

Step 2 : To calculate the area of larger circle.

Area of circle =

⇒ Area =    

            =  square inches

Step 3 : Calculate the probability that a point chosen from shaded region

Probability = Area of shaded region/Area of larger circle.

                  =  /

                  =  

                  =  0.36 = 36%

Step 4 : calculate the probability that a point chosen inside the larger circle is not in shaded region.

Probability = 1 - 0.36

                  = 0.64 = 64%

Hence the probability is 64%

Y = 2x + 1

Step-by-step explanation:

the slope is;

Change in "y"                     2

-------------------- (over) =     ------ or 2

Change in "x"                     1

The y-intercept is the point in the graph where a point in slope touches the y- axis and.

In this case the point is (0,1) so the y-intercept is 1.
