Answer:
36 runners finished the race.
Step-by-step explanation:
In the first half of the race, 1/4 of them dropped, so we need to calculate 1/4 of 80:
(1/4) * 80 = 80/4 = 20
If 20 runners dropped out, now we have 80 - 20 = 60 runners.
Then, in the second half, 2/5 of the remaining runners dropped out, so:
(2/5) * 60 = 2*60/5 = 120/5 = 24
If 24 runners dropped out, now we have 60 - 24 = 36 runners.
So, 36 runners finished the race.
The sum of two adjacent sides is 11 inches, so the long sides are 9 inches. The "unknown number" must be 12.
The answer is the first option
3y³-y²+8y-1+5/y-4. is that unless you want the answer smaller
-7/11
Step-by-step explanation:
-8s-4>3s+3=
-8s-3s=3+4
-11s=7
s=-7/11
