Use PENDAS it helps a lot.
Percent means parts out of 100
18%=18/100=1.8/10=0.18
0.18<0.70
18%<0.7
0.7 is larrger because math
1. The answer is d
2. The answer is a
3. The answer is a. The slope of a constant function is always 0.
S= (pi times r times l) + (pi times radius squared)
Factor out the pi times r
S= (pi times r) l + r
Divide
S/(pi times r)= l + r
Find common denominator and subtract
(S- pi times r)/(pi times r) = l
The answer therefore is A
Answer:
C because that's the only one that works
