You're question asks why the given mixed numbers are equal.
In fact, they're equal.
Lets make it easier for you to understand:
8 4/3 has a improper fraction "4/3", that fraction is over 1 whole.
You could look at 8 4/3 as:
8 + 3/3 + 1/3
The 3/3 turns into 1:
8 + 1 + 1/3
9 + 1/3
9 1/3
You would see that it turns into 9 1/3, therefore they are equal.
The amount of salt in the tank changes with rate according to
which is a linear ODE in 
. Multiplying both sides by 
gives
so that the left side condenses into the derivative of a product,
Integrate both sides and solve for to get
Given that 
, we find
and we get the particular solution
Answer:
angle 1 = 108°
Step-by-step explanation:
because angle 1 and angle 2 are vertical angles and vertical angles are equal.
Answer:
121 degrees
Step-by-step explanation:
The "arc length" formula is s = rФ, where Ф represents the central angle in radians (not degrees).
Here r = 18 ft and s = 38 ft, and so:
38 ft
s = rФ becomes Ф = ------------ = 2.111 radians
18 ft
which, in degrees, is:
2.111 rad 180 deg
------------- * --------------- = 121 degrees, to the nearest degree

<span>Hey there,
x^2 -6x+25=0
Per quadratic formula, roots of ax^2+bx+c are
x=[-b+sqrt(b^2-4ac)]/2a and x=[-b-sqrt(b^2-4ac)]/2a
In this example, a=1, b=-6, and c=25
So, x= [6+sqrt(36-100)]/2 and x= [6-sqrt(36-100)]/2
=> x = [6+sqrt(-64)]/2 and x = [6-sqrt(-64)]/2
=> x = 3+4i and x= 3-4i
Hope this helped you alot!!!!!!!!</span>
