75/100 = 0.75
--------------------
12 x 0.75 = 9
* The mine elevator travels a
distance of 9 metres per minute.
---------------------
After 2 minutes, the mine elevator
would've travelled 18 metres,
therefore your answer is:
A: -18 metres
Answer:
(x + 2/3)^2 + (y + 3/4)^2 = 5^2 (or 25).
Step-by-step explanation:
Start with the general equation of a circle with center at (h, k) and radius r:
(x - h)^2 + (y - k)^2 = r^2
Substitute -2/3 for h and -3/4 for k, and also 5 for r:
(x - [-2/3])^2 + (y - [-3/4])^2 = 5^2, or
(x + 2/3)^2 + (y + 3/4)^2 = 5^2 (or 25).
Geometry
You need to find the area of the square first.
8x8=64un^2
Then you must find the area for the four triangles.
8x6=42un^2
42un^2/2=21un^2
Then multiply this by four to find the area of all the triangles.
21un^2x4=84un^2
Then add the areas of the triangles and squares.
84un^2+64un^2=148un^2
