We have been that Arelli drank 2/3 liter of water Monday before going jogging. She drank 5/7 liter of water after her jog. We are asked to find the amount of water that Arelli drink altogether.
To find the amount of water that Arelli drink altogether, we will add amounts of water drank before going to jogging and after the jogging.
Let us make a common denominator.
Now we will combine numerators.
Therefore, Arelli drank 
liters of water altogether.
Answer: p = 1
Based on the assumption below.
Step-by-step explanation:
Is this 3p - 2 = 1? I don't quite understand the arrangement of the elements of the equation. I'll assume that since there is no operation sign for the "3," that it implies multiplication.
3p - 2 = 1
3p = 3
p = 1
Answer:
x = 8
Step-by-step explanation:
When cutting the wire we will get two pieces
x and 12 - x
If we build a circle whith x , the lenght of the circle will be x, and if we look at the equation for a lenght of a cicle 2*π*r = x
then r = x/2π
and consequentely A₁ = area of a circle = πr² A₁ = π*x/2π
A₁ = x/2
With the other piece 12 - x we have to make an square so wehave to divide that piece in four equal length
side of the square = s
s = 1/4 ( 12 - x ) and the area is A₂ = [1/4 ( 12 - x)]²
A₂ = ( 12 - x )²/16
Then A₁ + A₂ = A(t) and this area as fuction of x
A (x) = x/2 + 1/16 ( 144 + x² -24x) A (x) =[ (8x + 144 + x² -24x)]/16
Taken derivatives in both sides
A´(x) = 8 + 2x - 24 = 0
2x -16 = 0 x = 8 and s = 12 - 8 s = 4
