In mathematics, the Riemann hypothesis is a conjecture that the Riemann zeta function has its zeros only at the negative even integers and complex numbers with real part

. Many consider it to be the most important unsolved problem in pure mathematics (Bombieri 2000). It is of great interest in number theory because it implies results about the distribution of prime numbers. It was proposed by Bernhard Riemann (1859), after whom it is named.
Answer: x=64.
Step-by-step explanation:
48=3x/4
Multiply both sides by 4 : 192=3x
Divide both sides by 3. : x=64
Check: 64*3=192; 192/4=48 J=48 So x is 192.
Hope this helps! :p
Mode is the total average median is the middle number
Turning up the edges of the sheet metal will result in the 20 inches of
metal being divided into x inches of the first side, then the unknown
width of the gutter (let's call it "y") and then again x inches for the
second side.
As a picture:
x|______|x/y
As a formula:
20 = x + y + x = 2x + y
Resolving this to y we get:
20 - 2x = y
and switching it around:
y = 20 - 2x,
Now for part b) of your question:
The area of the gutter's cross-section is its width (y) multiplied with its height (x).
A(x,y) = x * y
If we use our result from a) to eliminate y then we can see that
A(x) = x * y = x * (20-2x) = 20x-2x^2
So I'd say that the answer to part b) should be:
A(x) = 20x - 2x^2
In this case, we'll have to carry out several steps to find the solution.
Step 01:
Data
7.1 x 10-3
standard form = ?
Step 02:
standard form
7.1 x 10-3 ====> 0,0071
The answer is:
0,0071
