One concert performance would be $275n. The concert hall owner's profit would be the net income, after subtracting any expenses, or what the person who played the concert hall charged. Therefore, before finding the net income, the equation for the total money gained would be $275n.
4.4354 rounded to 2 decimal places is 4.44
Answer: Lshonda will earn $23.
Step-by-step:
The equation would be (4•4.7) + (1•4.2)
4 multiplied by 4.7 is 18.8
1•4.2 is 4.2
18.8+4.2=23
hope this helps! :)
Answer:
13
Step-by-step explanation:
We can consider the complex number 
as point with coordinates 
where 
is real part of the complex number and 
is an imaginary part of the complex number.
The distance between two complex numbers is exactly tha distance between two points corresponding to each number.
Now find the distance between A and B:
Start with a proportion, to get the number of degrees in 30 seconds:
(150 degrees / 5 seconds) = ('D' degrees / 30 seconds) .
Cross multiply the proportion: (150 x 30) = 5 x D
4,500 = 5 x D
Divide each side by 5 : 900 = D
The globe turns 900 degrees in 30 seconds.
How many rotations is that ?
Each rotation is 360 degrees.
So 900 degrees is
(900 / 360) = <em>2.5 rotations</em> in 30 seconds.
