The scale ratio of a point A to another point B is the division of the length of B by the length of A. The best equation that models the situation is: 
The page dimension is:
The length and the width of Uche's book are equal; this means the pages of Uche's book have the shape of a square
The margin of 0.75 on either sided means the usable dimension is:
The dimension of India is:
The longest side in India's dimension is:
From Uche's book, the longest dimension is:
So, the scale equation is:
k * longest length of Uche's book = longest side of India
This gives:

Find the area of all the sides:
10 x 9 = 90
9 x 8 = 72
1/2 x 6 x 8 = 24
1/2 x 6 x 8 = 24
6 x 9 = 54
Add them up:
90 + 72 + 24 + 24 + 54 = 264 square metres
A) k=55
b) 55t=w
c) It will take elizabeth seventeen minutes.
Answer:
11/60
Step-by-step explanation:
sin x = opp/hyp
cos x = adj/hyp
tan x = opp/adj = (opp/hyp)/(adj/hyp)
tan x = (11/61)/(60/61)
tan x = 11/61 * 61/60
tan x = 11/60
We have that
x²+y²-4x-6y-12=0
Group terms that contain the same variable, and move the constant to the opposite side of the equation
(x²-4x)+(y²-6y)=12
Complete the square twice. Remember to balance the equation by adding the same constants to each side
(x²-4x+4)+(y²-6y+9)=12+4+9
Rewrite as perfect squares
(x-2)²+(y-3)²=25
the answer part A) is (x-2)²+(y-3)²=5²-----> this is the standard form of the equation of a circlePart B) (x-2)²+(y-3)²=5²
the center is the point (2,3) and the radius is r=5 units
Part C)
