Answer:
remainder = 
Step-by-step explanation:
The remainder is the value of the subtraction of the last 2 lines in the procedure.
5x - 9
- (5x - 10)
That is
5x - 5x = 0 and - 9 - (- 10) = - 9 + 10 = 1
over the divisor x- 2 , gives
remainder = 
Answer: The amount of white fabric to coloured fabric as a ratio in its simplest form is 
Step-by-step explanation:
Given :
Amount of coloured fabric used by June = 11 mm = 1.1 cm (1 mm=0.1 cm)
Amount of white fabric used by June = 1 cm
To find : amount of white fabric to coloured fabric as a ratio in its simplest form
To find the ratio in simplest form , the units of both measurements should be same
Thus 
The amount of white fabric to coloured fabric as a ratio in its simplest form is 
A^2 +b^2 =c^2
c^2 will be your hypotenuse
Hope that helps
Answer:

Step-by-step explanation:
Use trigonometry
Recall that cos(x)=adjacent side/hypotenuse
You can remember this with SohCahToa
Also remember that if cos(x)=y then 
In this case, we know the adjacent side and hypotonous
Adjacent side=5000
Hypotenuse=13000
Therefore

Now to solve for x, take the inverse cosine
