The first thing we need to know is how much grass the grasshopper needs to eat.
We have:
"must eat half its body weight in grass each day":
(2 grams) * (1/2) = 1 gram
Then,
"1 blade of grass weighs 0.1grams"
Then the amount you need to eat is given by:
N = (1) / (0.1)
N = 10 blades of grass
Answer:
the grasshopper needs to eat 10 blades of grass each day
Answer:
-1/4
Step-by-step explanation:
- -1/2+1/4=-1/4
- -1/4+1/4=0
- 0+1/4=1/4
- 1/4+1/4=1/2
But in reality, it is going from positive to negative, so the answer is -1/4.
we know that
