Answer:Second Step
Step-by-step explanation:
On the right side in step two you added -3b-15b, and ended up with -12b. This is incorrect. -3b-15b is actually -18b
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
One number is 26 the other is 23
x+y=49
Y=x+3,X (now substitute it in the equation)
x+3+x=49
2x+3=49
2x=46. X=23
Y=x+3. Y=23+3 =26 for checking 23+26=49
15:3 is the only equivalent ratio to 20:4.
Answer: x=1
