429.99 + 0.34m or in slope intercept format y = 0.34x + 429.99
The answer is 6.25 pi cm squared
Answer:
9.08 hours
Step-by-step explanation:
in order to fill 1 pool
fill rate by pipe = 1 pool / 15 hours = 1/15 pool per hour
fill rate by hose = 1 pool / 23 hours = 1/23 pool per hour
combined rate = fill rate by pipe + fill rate by pool
= 1/15 + 1/23 = 38/345 pool per hour
since:
38/345 pool -----------> will take 1 hour
1 pool --------------------> will take 1 hour x (345/38) = 9.08 hours
The slope-intercept of the line is
y= -2/3x + 2
Going up 2, left 3
Change in y
------------------
change in x
