Answer:
First = Poppy seed = 3x10^-4 grams = 0.0003 grams
Second = sesame seeds = 3.64x10^-6 grams = 0.00364 grams
third = 250 pumpkin seeds 21 grams = one seed 0.084 grams
Step-by-step explanation:
3.64x10^-6 kilograms *1000gr/Kilograms = 0.00364 grams
21/250 = 0.0084 grams one seeds
The answer to this would be 34.5
Answer:
144π
Step-by-step explanation:
we need the radisu
circumference formula: 2πr
2πr=24π
12=r
area formula:
πr²
12²π= 144π
Work backwards. If there were 14 at the end, then multiply this by 3/2 because 2/3 of the marbles were given to Sam. so 14 times 3/2 is 21. There were 28 total because if you add 1/3 to 1/6 you get 1/2. So they they lost 1/2 of the marbles and got 1/4 of the original amount back, which was 21.
So the original number was 28. Hope this helps!
Answer:
C) I and III only
Step-by-step explanation:
Let full pool is denoted by O
Days Hose x takes to fill pool O = a
Pool filled in one day x = O/a
Days Hose y takes to fill pool O = b
Pool filled in one day y = O/b
Days Hose z takes to fill pool O = c
Pool filled in one day z = O/c
It is given that
a>b>c

Days if if x+y+z fill the pool together = d
1 day if x+y+z fill the pool together 
I) d < c
d are days when hose x, y, z are used together where as c are days when only z is used so number of days when three hoses are used together must be less than c when only z hose is used. So d < c
III) 
Using (1)

Similarly

So,
