The price of an item has dropped to $39 today. Yesterday it was
Kobotan [32]

Answer:

40% decrease

Step-by-step explanation:

First, let's find the value decrease of the item from yesterday to today

$65 - $39 = $26

That means that $65 was 100% of the price and decreasing it by 26 gets us to 39

We need to find the percentage of 39 in 65

39/65 = 0.6 or 60%

If 39 is 60% of 65, then there was a 40% decrease form 100%

To check we can calculate the percentage of 26 in 65:

26/65 = 40%

There was a 40% decrease

Determine which system below will produce infinitely many solutions. (2 points)
disa [49]
The only system that has infinitely many solutions is NUMBER 2. Where you solve a system, and both sides end up being 0=0, then the system will have infinitely many solutions. Well, in these four choices, Number 2 is the only one that ends up being 0=0 after I solved it.

A particular circle in the standard (x,y) coordinate
matrenka [14]
For any circle with Cartesian equation
(x-a)^2 + (y-b)^2 = r^2,
we have that the centre of the circle is (a,b), and the radius of the circle is r.

So in the case that 
(x-5)^2 + y^2 = 38,
we essentially have that
a = 5, b = 0, r^2 = 38.

So the centre of the circle is (5,0), and the radius is \sqrt{38}.
