There were 60 runners to start a race. In the first half of the race, 23 of them dropped out. In the second half of the race, 34 of the remaining runners dropped out. How many runners finished the race?

3

Step-by-step explanation:

Total no. of runners = 60

After the first round: 23 of them are dropped

Therefore No. of runners after the first round is 60-23= 37

After the second round: 34 of them are dropped

Therefore no. of runners after 2nd round is

37-34 = 3

The no. of runners finishing th race is 3

Hope this answer helps...

the thermometer is precise but not accurate

step-by-step explanation:

-3

step-by-step explanation:

a drawing really does here:

so i draw the horizontal line y=2 and the vertical line x=-2 at this intersection i put b (this is where my right angle is going to be).   so point b is at (-2,2).   point a is 5 units long and is also on y=2 so this point has to be (3,2) or (-7,2) -doesn't matter i will go with (3,2).

now we know c is at (-2,y) we don't know the y yet bet we know that c is on x=-2.

we have the area of the triangle is .5bh=12.5

we know the base length is 5 (ab)

we have the height is (2-y) if you look at your

plug in

.5(5)(2-y)=12.5

solve for y to get the y-coordinate for c

2.5(2-y)=12.5

divide both sides by 2.5 giving:

2-y=5

now subtract 2 on both sides

-y=3

y=-3
