Together a pineapple and a watermelon weighs 6 kilograms 230 grams. if the pineapple weighs1 kilogram 255 grams how much does the watermelon weighs

P + W = 6.230 kg

P = 1.255 kg Therefore,

W = 6.230 kg -P

W = 6.230 - 1.255

W = 4.975 kg or 4 kg   975 grams

he spend 5.1 minutes chatting with his friends

step-by-step explanation:

2/5+1/2=9/10

6/1-9/10=5 1/10

< coa = 150 ( given)

as ba and bc are tangents

so oc and oa is perpendicular to cb and ab respectively because in circle normal passes through centre

so in quadrilateral oabc

< coa + < oab + < ocb + < abc = 360

150 +90+90 + < abc = 360

330 + < abc = 360

< abc = 360 -330 = 30

so < abc = 30
