Hi there! :)

Let x = number of pounds of grapes and y = cost in dollars:
Find the constant of proportionality by finding the price per pound:

Therefore, the constant of proportionality is H. 2.19
Answer:
We just finished this in geometry and i hated it lol but i think <DBA and <CBA are equal and AD=AC
The answer is 0.525 m per s
We would get this by adding up the total distance which was 10.5 and dividing by the total time which is 20 minutes.
Answer:
I think x is 1/2.
Step-by-step explanation:
Because the triangles are similar, you can set 9x + 1 = x + 5. Subtract x and 1 from both sides to get 8x = 4. divide and you get x = 1/2.
(double check me though.)
Answer:
5575 cm³
Step-by-step explanation:
The volume of a sphere is V = (4/3)πr³. If we substitute r = (d/2 where r is the radius and d the diameter), this formula becomes:
πd³
V = (4/3)π·d³/8, or V = -------------
6
and so, if d = 22 cm, the volume is:
π(22 cm)³
V = ------------------- = 5575 cm³
