Answer:

10%

Step-by-step explanation:

Given:

Total number of racers = 270

Number of racers completed the race = 243

Number of racers gave up = 20

Now,

The number of racers who did not complete the race

= Total number of racers - Number of racers completed the race

= 270 - 243

= 27

Therefore,

The percentage of racers who did not complete the race

= \frac{\textup{number of racers who did not complete}}{\textup{Total number of racers}}\times100\%

= \frac{\textup{27}}{\textup{270}}\times100\%

= 10%

The equation of a circle is ( x - 3) 2 + ( y + 2) 2 = 25. The point (8, -2) is on the circle.
Shtirlitz [24]

Answer:

x =8 is the equation of the tangent.

Step-by-step explanation:

Here the equation of the given circle is: (x-3)^{2}  + (y+2)^{2}  = 25

Now, comparing it with the general equation of circle: (x-h)^{2}  + (y -k)^{2}  = r^2

we get the central coordinates (h,k)  = (3,-2)

So, the slope of the line joining center and (8, -2) = \frac{-2 -(-2)}{8-3} = \frac{0}{5} = 0

Since the slope of line = 0, line is parallel to x axis.

Now, as tangent and the line is perpendicular to each other

⇒Slope of the tangent = -1/ slope of the line = \frac{-1}{0}

Now, by point slope formula: the equation of the tangent is

(y-y0)  = m (x-x0)

or, (y +2) = \frac{-1}{0} (x -8)

or x =8 is the equation of the tangent.

Please tell me answer not by directly step by step please don't write answer only please please please
irinina [24]

Step-by-step explanation:

Given,

y=2x=,z=3x,r=4x

Now,

x+y+z+r=360°(complete turn)

x+2x+3x+4x=360°(given)

10x=360°

x=360°/10

x=36°

Hence,

x=36°

y=2x=2×36°=72°

z=3x=3×36°=108°

r=4x=4×36°=144°
