Let s be standard and h be high-quality versions of the song.
To figure this out, let's make a system of equations:
2.5s + 4.5h = 5740
h = 4s
First substitute the second equation into the first for h.
2.5s + 18s =5740
Then combine like terms.
20.5s = 5740
Lastly, divide each side by 20.5 to get the number of standard downloads:
s = 280
Hope this helps!
You will use trig. Try the phrase “SohCahToa” you will use “Soh” meaning Sin is opposite over hypotenuse. So in this instance, it would be sin(x)=8/11. You will need to take the inverse sine to figure out x. So, x= sin^-1(8/11) which turns out to be approximately 46.65°
In this item, we are asked to identify which among the given choices is a property that is being shown by the equation,
(mn)⁵ = m⁵n⁵
It can be observed that m and n are multiplied to each other, inside the parentheses for the expression written on the left side of the equation. Also in the right hand side of the equation, 5 which is the power, is distributed to the elements m and n.
The property that is being depicted in this number is the power of a product property. Thus, the answer to this item is letter B.
