Answer:
(a) 72 tiles
(b) 54 tiles
Step-by-step explanation:
Total perimeter of the pool = 6 + 6 + 4.8 + 4.8 = 21.6 meter.
The tiles are in centimeters so...21.6 m x 100 = 2160 cm.
(a) 2160 divided by 30 = 72
(b) 2160 divided by 40 = 54
Top/Bottom = 12
Sides = 15
Front/Back = 20
20 + 15 + 12 = 47
47 / 1/2 = 23.5
x + 3 = 0.
One would be:
x + 3 = 0 Subtract 3 from both sides:
x + 3 - 3 = 0 - 3
x = -3
72 degrees
