Answer: 11
Step-by-step explanation:
If 15 workers can paint 18 houses in 24 days, how many days will 40 workers take to paint 22 houses?
--------------
# of days are inversely related to # of workers and directly related
to # of houses.
--------------
d = kh/w
---
Solve for "k" using "15 workers can paint 18 houses in 24 days"
24 = k*18/15
k = 15*24/18 = 15*(4/3) = 20
--------------
Equation:
d = 20h/w
---
Solve: How many days will 40 workers take to paint 22 houses?
d = 20*22/40
d = 11 days
Answer:
4. (-2 1/2, 4 1/2)
Step-by-step explanation:
Midpoint Formula is (x1+x2)/2, (y1+y2)/2
So (-6+1)/2 , (1+8)/2 = (5)/2, (9)/2 = (2.5,4.5)
And that in fraction form is (-2 1/2, 4 1/2)
