Answer:
Step-by-step explanation:
A) You are painting 5 faces, four sides and the bottom, of the pool because you are not painting the top of the pool.
B) You need 104 square meters to paint the pool.
Assuming the pool is a rectangular prism, use the surface area equation:
SA = wl + 2(hl) + 2(hw)
Note: Do not include times 2 for wl because we are only including the bottom of the pool.
l = 8 meters
w = 6 meters
h = 2 meters
SA = (6)(8) + 2((2)(8)) + 2((2)(6))
SA = 104 square meters
C) The paint with cost $624 total. $104 times 6 square meters equals $624

b) The relative error is given by:
c) The percentage error is:
Answer:0.518518519
Step-by-step explanation:
Answer:
-16
Step-by-step explanation:
Represent the number by n.
Then:
8(n + 18) = 16
Performing the indicated multiplication, we get:
8n + 144 = 16
Subtracting 144 from both sides results in 8n = -128.
Dividing both sides by 8: n = -128/8 = -16
The number was -16.
