Out of 290 racers who started the marathon, 259 completed the race, 28 gave up, and 3 were disqualified. What percentage did not complete the marathon?

10.68%

Step-by-step explanation:

Total no of racers = 290

No of racers that completed the race = 259

No of racers that gave up = 28

No of racers that were disqualified = 3

No of racers that did not complete the marathon = 28 + 3 = 31

We need to find the percentage of the racers did not complete the marathon. It can be given by :

So, the percentage of the racers that did not complete the marathon is 10.68%.

5=812a+9+3

step 1: simplify both sides of the equation.

5=812a+9+3

5=(812a)+(9+3)(combine like terms)

5=812a+12

5=812a+12

step 2: flip the equation.

812a+12=5

step 3: subtract 12 from both sides.

812a+12−12=5−12

812a=−7

step 4: divide both sides by 812.

812a /812 = -7/812

a= -1/116

so the answer is

a=   -1/116

the formula for the equation of a circle is (x – h)2+ (y – k)2 = r2, where (h, k) represents the coordinates of the center of the circle, and r represents the radius of the circle. if a circle is tangent to the x-axis at (3,0), this means it touches the x-axis at that point.
