HELP! Water comes out of a garden hose at a constant rate to fill a pool. After 3 minutes, the pool is filled with 30 gallons of water. After 6.5 minutes, the pool is filled with 65 gallons of water

a. Write an equation that represents the number of gallons of water y in the pool after x minutes

b. How long will it take to fill a pool that needs 10,000 gallons

< 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

12

step-by-step explanation:

12 + 5 = 17

12x2=24

24-7=17

236 cm 16 time 12 = 192

6 times 7 = 42

192+42

to find the perimeter, you add up all the lengths of the sides. in this case you would have to add up 18+22+40+80 which equals 160.
