Answer:
Adam payed $4.25 for 5 lbs of walnuts. The equation for this is 5.75p-4.50
Step-by-step explanation:
The reason this is the eqaution is because 5.75 is the price per pound. "p" represents how many pounds and -4.50 is the coupon.
6(x+5)² + 5(x+5)-4 = 0
(x+5)(x+5) = x(x+5)+5(x+5) = x² + 5x + 5x + 25 = x² + 10x + 25
6(x²+10x+25) + 5(x+5) - 4 = 0
6x² + 60x + 150 + 5x + 25 - 4 = 0
6x² + 60x + 5x + 150 + 25 - 4 = 0
6x² + 65x + 171 = 0

Answer:
It's C
Step-by-step explanation:
6.292
1kg=9.69
1000g=9.68
650= 9.68/1000x650=0.00968x650
=£6.292
V=hpir^2
d/2=r
so, at first, diameter is 48ft
48/2=24ft is radius
height is 25ft
so volume=25pi24^2 or 14400pi cubic feet
max of 9ft
if we want 9ft height
find r
hmm
14400pi=9pir^2
divide both sides by 9pi
1600=r^2
sqrt both sides
40=r
2r=d
2(40)=80=d
the new diameter is 80ft
