Answer:
Step-by-step explanation:
y=ax²+bx+c
x=0,y=0,c=0
y=ax²+bx
2=9a+3b (×-5)
3=25a+5b(×3)
add
9-10=75a-45a+15b-15b
30a=-1
a=-1/(30)
2=9×(-1/30)+3b
3b=2+3/10=23/10
b=23/30
y=-1/30 x²+23/30=-1/30(x²+23x+(23/2)²)+1/30 ×(529/4)
y=-1/30(x+23/2)²+529/120
the bottle of waters costs 0.09 cents per ounce.
It's 7/24 so about 0.292
therefore it will be close to 1/4
or you calculate 1/8 = 0.125 and 1/6 = 0.1666 adds up close to 1/4
Answer:
3/4
Step-by-step explanation:
for every 2 yellows there will be 3 pinks for every 3 pinks there will 5 blues C = 4 ÷ t = 3/4 :)
hehehe i don't even know what the freak i just said
Step-by-step explanation:
Putting the value of r
3 ( 1/6) 2
So 3 × (1/6) = 0.5 × 2 = 1
