Answer:
1+2+3+4+5+...+=1/12
Step-by-step explanation:
ANSWER IS 12
The total is the 100% and that is 27000, the question is what percentage is 4865
We can use a simple rule of three, direct proportion to solve:
27000 ft^3 --------> 100%
4865 ft^3 ---------> x
x =(4865)(100)/27000
x = 18.02
therefore 4865 ft^3 is 18.02% of 27000 <span>ft^3</span>
Answer:
17.5 + 15.5
Step-by-step explanation:
17+ 15 = 32
.5 + .5 = 1
32 + 1 = 33
A complement angle mean that make with angle E together 90 degrees
7x-12 + angle complement = 90
angle complement = 90 -(7x-12)
angle complement = 90 -7x +12
angle complement = 102 -7x
so choice b. is right sure
