D=(1/2)*a*t²
Multiply both sides by 2
2d= a*t²
Divide both sides by a
2d/a=t²
Now take square root both sides. You will get t in terms of d and a

You just divide 0.72 by 0.36 which gives you 2. then you multiply that by 2 which gives you an answer of 4
Answer:
1000.
Step-by-step explanation:
We need 4 weights where 3 of them add up to
900, 1400, 1600 or 1800g.
Not sure of the method for doing this!
Lets assume that the answer is 1000 g.
Then the 3 that make 1800 could be
1000 500 and 300
- then to make 900 we need a 100g tomato giving:
1000 500 300 and 100 grams
So the 1400 will be the 1000, 300 and 100 tomato
and the 1600 will be 1000, 500 and 100.
That seems to fit !!
