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
Answer: $14.85
Step-by-step explanation:
Answer:
B
Step-by-step explanation:
Volume is length · width · height, so you can add another column with the volumes:
8
9
6
3
Then you see that 9 is the highest volume.
Answer:
x=5 and y=5
Step-by-step explanation:
You "plug" one equation into the other, to get a new equation that only has one variable (x or y), then you can simplify that and have your answer.
So let's plug the first into the second:
First, we convert the first equation into an x=... form. For this one, this means moving the +y to the other side:
x = 10 - y
Now we substitute 10-y for x in the second equation:
So 2x+4y=30 becomes:
2(10-y) + 4y = 30
And simplify that:
20 - 2y + 4y = 30
20 + 2y = 30
2y = 30-20
2y = 10
y = 5
This is the first answer! If we put this into the first equation, we get:
x = 10 - 5 = 5
Now we have both answers, x=5 and y=5
We know that
a1----------> <span>grains of rice in the first square
a1=2
n------------> space ubication
the expressions is
an=a1</span>^n----------> an=2<span>^n
for the </span><span>the tenth space n=10
</span>an=2^10---------> an=1024 grains of rice
the answer is
1024 grains of rice
