The first one I THINK is 21 and the second one I THINK is 20. I'm not sure though sorry if I'm wrong
Answer:
700π m ~ 2199 m
Step-by-step explanation:
diameter = d = 200 m
2 min 20s = 140 s
1 round / 40 s
140 = 40 * 3 + 20
so the athlete will cover 3 round and half
1 round = d * π
covered = c = 3 * 200 * π + 200/2 * π = 700 * π
Smart boy you beryyyy smarttt
Answer:
2x^2t + 7xy
Step-by-step explanation:
I'm guessing you want this simplified, since you have not specified what to do,
5xy + 2xy = 7xy
-x^2t + 3x^2t = 2x^2t
= 2x^2t + 7xy
The total would be 24 dollars.
