GM= ( II i = 1 xi) 1/N
for example, {3,4,2,6}.
GM = (3*4*2*6) 1/4
GM = 144*1/4
GM ~ 3.464
A) it would be a ratio of 5:1, y=5x
B) if x is 12, it has doubled, so you do the same to y, so it would be 60
I think its A 93 cm because when i work out the problem i get 93
Answer:
137 ft²
Step-by-step explanation:
The shop is rectangular in shape. The area of a rectangle is given by:
Area = length * width
Since the length of the shop = 20 ft and the width = 10 ft, therefore:
Area of the shop = length * width = 20 ft * 10 ft = 200 ft²
The part that would not be tiled is of triangular shape. The area of a triangle is given as:
Area = (1/2) * base * height
The base of the triangle = 18 ft, the height = 7 ft. Hence:
Area of non tiled part = (1/2) * base * height = (1/2) * 18 ft * 7 ft = 63 ft²
The total square feet of tile needed to complete the job = Area of shop - Area of non tiled part
The total square feet of tile needed to complete the job = 200 ft² - 63 ft² = 137 ft²
