Answer:
40+2s=60-3s
Step-by-step explanation:
The red balloon starts 40 feet off the ground and rises 2 feet per second. This means the height of the red ballon is 40+2s.
The blue balloon starts 60 feet off the ground at starts falling 3 feet per second. This means the height of the blue balloon is 60-3s.
Because we want to find out when the balloons will be the same height, we set them equal to each other.
40+2s=60-3s
Answer:
what are the numbers at my guy
N = N₀* 
where N is how much you currently have
N₀ is the starting amount
t is the time
and h is the half life of the substance.
A cause you just gotta think about it and realize you got it
A = bh
A = 5.4 x 3.8 = 20.52
20.52 x 4 = 82.08
So, the answer is 82.08 m^2
