Choosing the coaches of the basketball teams is independent because which girl he chooses does not influence nor is it influenced by the choice for the boy
The non perfect square is 24
First, we convert it into a unit like this
20 workers × 30 days = 600 units work
After leaving the 5 workers, we have 35 days to complete the work.
In 35 days only 15 workers will do the work.
So the work completed in 35 days by 15 workers = 35 ×15 =525 units
Remaining unit = 600 -525 =75 units
This unit would do by 5 workers in (75/5) = 15 days.
So after 15 days, 5 workers should leave the job.
<span>2x^2+10x= -8
</span><span>2x^2+10x+8 = 0
2(x^2 + 5x + 4) = 0
2(x + 4)(x + 1) = 0
x + 4 = 0; x = -4
x + 1 =0; x = -1
answer
x = -4 and x = -1</span>
Answer:
It will leave the sprinkler at speed of
Step-by-step explanation:
We have given internal diameter of the garden hose
So radius
So area
Water in the hose has a speed of 4 ft/sec
So
Number of holes n = 36
Diameter of each hole
So radius
So area
From continuity equation
