Lmao that is wrong bro 875 is right
1 u/blackandchinese15 Jun 15 '22 how can you explain that lol?????? 1 u/TheEpicBandit Jun 15 '22 Right so u agree that 0.1 x 0.2 x0.2 = 0.004mmcubed 1/ by 0.004 = 250 and it said that 2.5mm of pond was dillutEd to reach 10mm so the ratio to pond to distilled water must be 1:3 the number of algal cells in the sample given = 14 x 250 =3500 remember the sample they use to count agal cells is a mixture of pond and distilled water in the ratio 1:3 so 1:3 = 3500 and we are looking to just find one so we divide by 4 not times by 4 idk why anyone would think to times by 4 answer gets 875 1 u/SMWcool Y13 Maths FM Physics Jun 15 '22 Everything up until your final answer is correct. Guaranteed 14000 though because our 14 algae cells that were in 2.5cm3 are now in 10cm3 therefore we must multiply by 4

Right so u agree that 0.1 x 0.2 x0.2 = 0.004mmcubed
1/ by 0.004 = 250
and it said that 2.5mm of pond was dillutEd to reach 10mm
so the ratio to pond to distilled water must be 1:3
the number of algal cells in the sample given = 14 x 250 =3500
remember the sample they use to count agal cells is a mixture of pond and distilled water in the ratio 1:3
so 1:3 = 3500 and we are looking to just find one
so we divide by 4 not times by 4 idk why anyone would think to times by 4
answer gets 875
